[DISCLAIMER] Images are provideded "as is", use at your own risk!
[NOTE] This project is no longer maintained!
Quite a few people seem to end up in non-bootable-states (myself included) when trying to root/app/tweak etc..
So I made a couple of images that will help you trigger Factory Restore on your Nook Simple Touch.
Compability:
Nook Simple Touch - [1.0.0], [1.0.1], [1.1.0]
Requirements:
- A microSD card of atleast 128MB of size (existing data will be lost)
- Make sure your NST is charged! A failed root will drain your NST quickly without you noticing it!
Tools:
- Windows: win32 Disk Imager
- Linux: d'uh .. dd
- Mac: diskutil and dd
Still unsure about tools?, look here
Versions: (You only need one of these depending on how messed up your NST is. Try 0.1 first!)
- Version 0.1 [Without boot partition restoration] n2T-Recovery_0.1.rar (2MB)
- Version 0.2 [With boot partition restoration] n2T-Recovery_0.2.rar (16MB)
Usage:
- Uncompress the image
- Write the image to your mSD card with one of the tools listed above.
- Power up your Nook Touch with the mSD card inserted.
- Follow the instructions displayed on the screen.
If all went well you should see the factory restore screen popping up in 10-20 seconds after reboot, and you'll be back to the version your NST was originally shipped with* when it's finished.
If it doesn't, please share your "detailed" story in this thread and feel free to PM me, I've restored quite a few "hopeless" cases
[*] Factory Restore doesn't wipe your /data
Update:
26.11.2012 - Added new download links
28.01.2012 - Moved files to new server
Changelog:
[0.1]
- Initial release
[0.2]
- Rewrites boot partition before triggering Factory Restore
Credits:
- Based on Nook Simple Touch 1.0.0 boot partition
- Made possible by Noogie image by nookDevs
Scary!
But good solution when everything else fails. Thanks!

Nothing scary about it, it only writes to a single file on your N2 to trick it into believing there has been 8 missed boot attempts.
That is good to know, because timed things on smartphone and the like is a usual way to messy results. Try putting an iphone in DFU mode in order to jailbreak it...

Ah I see your point, but there's really no timing involved with this process.
Cleaned up the instructions a little, thank you.
Did Not Completely Restore, But...
I was able to restore by the following:
1. Tried your method on a rooted (1.00 FW) Touch but it seemed to hang on the last bit of rebooting.
2. I wrote the factory 1.01 update to an SD card using Winimage, turned the Touch off, put the SD Card in, turned the Nook on, let it go to sleep (per BN Instructions for applying update) - it woke up, applied 1.01 and unrooted simultaneously.
3. Reregistered and rerooted using ManualNooter.

do you have a link for the .img for the update? I only found a zip file, not sure how to use Disk Imager to put that on there.
But yeah, I'm experiencing the same issue, hangs on the reboot part.

I have never seen or even heard of a 1.0.1 update image.
The 1.0.1 update is distributed as a zip file that has to be saved on the Nooks internal storage trough usb. This makes no sense to me.

Answers -
1. By "hanging" I meant it's stuck on the last little bit of writing the restore img - never quite finishes.
2. Just go to BN site and you can download "update.zip 1.01" for the Touch - it gets applied by placing on the root of the internal memory and booting up
3. My Bad - I meant TouchNooter

Ok, so the factory restore got triggered but didn't complete, wonder why.
Did you try to trigger restore again?
I'm gonna look into adding more advanced recovery options to the tool.

Yes I know, but you said you wrote it to sdcard with winimage, which didn't make any sense
The only way I can get my nook to boot into a usable environment is by way of a touchnooter bootable mSD. I managed to move the 1.0.1 update onto the NOOK patition, but I had to boot off of a noogie SD (for some reason, USB mode doesn't work when I boot off of touchnooter)to do so. Even after letting it go to sleep, it doesn't seem to recognize that there's an update. I have no clue what to do.
EDIT: Tool is a lifesaver.

I've replied to your PM.
Thanks for this img. Accidentally powered off the Nook with a core android file missing and when I turned it back on, I was stuck on a looping 5-dot start up screen. This gave me a very easy way to fix it and didn't really erase anything, either. The TN stuff was gone, but every app I'd installed myself after rooting with TouchNooter remained, as did my launcher and setup, etc.
Glad to hear it worked for you
I also have new version under testing that will help people with more severe problems.
mrmystery96 a few posts up had a completely broken boot partition after some app/mod tried to write its recovery there.
He got a development copy from me last night and he was able to successfully restore his Nook Touch, so I should be able to release it in a day or two.
How long is it generally expected to take? I'm just looking at a blank (but backlit) screen with your sd image.
I dd'd the file to the root of the sd card (/dev/sdc), not any partition. Is it supposed to be on a partition?

Ciao, I have a problem...
I rooted my nook, it was working, but it seems to me slower when it opens a book, and sometimes it crashes opening a book.
So I would like to restore.. I saw your post: fantastic!
I downloaded the image, i copy ect i followed all the instructions..

The built in "Factory Restore" doesn't wipe everything, it just restores important parts of your system.
If you want to clean your NST you can boot it while pressing both left and right bottom buttons (it will trigger Factory Reset (not restore))
If you want your NST absolutely 100% clean, I'm sorry to say that you should have made a backup before rooting it

You can't.
Every NST contains unique data so it's not possible to make a generic restore image. It is possible to make one customised to your NST tho, I've made a few of those.

Just press the power button until you see the screen flicker, then immediately press and hold those buttons until you see the "Factory Reset" screen, then follow the instructions on the screen.
[HOWTO] ClockworkMod Recovery & TWRP - Upgrade/Downgrade (Touch/Non-Touch Recovery)
IF YOU TRASH YOUR PHONE USING THIS PROCEDURE, THEN IT IS A VERY GOOD INDICATION YOU ARE AN IDIOT AND SHOULD NOT BE FLASHING ANY ROMS NOR PARTICIPATING ON THESE FORUMS. . . . JUST SAYIN'. . . .
Please be VERY careful when using this method as you can brick your phone. Make sure you triple check the file you downloaded is the right size and placed in the right area, but most importantly that the command lines you type are exactly right. If you are not comfortable using this method, then please do not and go find a flashable version of these recoveries.
I've posted a procedure to format/'flash' your recovery while on your phone in one of the threads on here and was asked by a Forum Mod to make a quickie guide to be placed as a sticky on the dev boards so others might benefit.
Anyway, here is a very quick and easy way to change your ClockworkMod recovery with a couple of command lines.
The TWRP link is in the second post.
Now for the ClockworkMod Instructions:
1. First, go here and look up your ClockworkMod recovery that pertains to your phone: http://www.clockworkmod.com/rommanager
2. Download the .img file for your phone and save it on your computer.
3. Rename the .img file to recovery.img and save it to your internal sd card of your phone. For example: recovery-clockwork-6.0.1.4-hercules.img ------> recovery.img
4. Open up Terminal Emulator on your phone and type the following 2 commands:
su
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p22
(please note the second command is a one line command with spaces between "dd & if=" and ".img & of=")
If your Rom identifies your internal sdcard as /emmc instead of /sdcard, then make the adjustment to command line (dd if=/emmc/recovery.img) instead of what is posted above.
That simple.
You can also issue these commands from adb shell if you are connected to your computer.
If Terminal Emulator does not have Superuser or SuperSU permissions for root privileges then make sure it does. You can also go from NON Touch CWM to Touch CWM using this and vice versa. Simply make sure you have the right recovery for your phone and rename it to recovery.img.
As for explanations:
dd if= command is a common Unix program whose primary purpose is the low-level copying and conversion of raw data.
dd stands for "data description"
if stands for "input file"
of stands for "output file"
the = is the location of the data you are using. ie. /sdcard/recovery.img
the /dev/block/mmcblk0p22 is the location/partition of the recovery on your phone.
So essentially you are doing a low level rewrite of the recovery image on your phone via command lines.
***Also, the best way to remember this command line is to not to. Copy the command line and save it to your own personal contact info in Google under Notes and then you will have it with you wherever you go. You really do not want to mess with getting it wrong. You could brick your phone if you mess things up.
Anyway, I hope this helps. . . . it really is very easy to execute without fault.
Works with TWRP too.
This also works with changing to and from TWRP. Download the image (for our phones it's TWRP 2.3.1.1) rename it to recovery.img and follow the above instructions and you are good to go.
Follow this link to get the image file: http://teamw.in/project/twrp2/101
***I attached the old TWRP 2.2.2.0 is case you run into problems with the newer versions not restoring backups properly or renaming backups correctly.***
Excellent Thread, I hope Dev's requiring specific CWM versions can link to your post.
Thanks for your efforts.

Thanks for the instructions! Thanks even more for explaining the command lines.
Just thought I'd point out a small bug with the Touch Recovery. If you flash one of the newer ICS roms like Darkside Evolution through the Touch Recovery, once booted, the ROM WILL NOT SLEEP through time out. I've confirmed this with 2 separate ICS roms. Flashing non-touch recovery through Rom Manager fixes this problem.
Wouldn't it be easier to use gscript and run the commands as you need them?
Thanks for the HOW TO I actually was looking for it.
What is wrong with ROM Manager? I use it to go between Touch and normal all the time and it works flawlessly.

For some people Rom Manager doesn't work. On the T-Mobile SGH-T989 Galaxy SII, Rom Manager will only allow you to go to 5.0.2.6 not 5.0.2.7. And, I think you have to upgrade Rom Manager to go to Touch. I bought Rom Manager, and don't use Touch Recovery, so I am not sure.
I like to use the command structure verses program because I know it works, it's fast, and I can see the results if an error occurs.
Oh yeah...this was really simple...Thanks...went from Touch back to Non Touch.
Give this a try
If you want a simple way to flash the Touch Recovery then give this a try. I will be adding the Hard Recovery as well in the next release.

Haha no worries bro. I mean worries that it failed for no reason, but I already sent it in, he just got it today. Same person you linked. Definitely trying to install ics again when i get it. Plus I think the ota ics for tmo came out yesterday or something? Probably a better experience than what was already out there with the radio and stuff.

No! Do NOT use this procedure with that file extension!
What recovery are you trying to install? And for what phone? I briefly ran my cursor over the various files and the download links are either .img or .zip files. I did not see .ndif file extension.
PM me if you need additional help.
Would you happen to have the .img file for 5.0.2.7??
Edit* Nvm.. a quick google search and I was able to find it. You are a life saver.. I tried updating my recovery to the 6.0.1.2 Hercules port and for a couple days, it was working great up until an hr. ago. Nothing would flash and it would just hang in recovery... so I found this thread and thankfully I was able to downgrade back down to 5.0.2.7.
If you were local, I would take you out and get you piss drunk for helping me save my device. Cheers!!!!

Good news! You made front page! http://www.xda-developers.com/andro...gn=Feed:+xda-developers/ShsH+(xda-developers)
Hello,
In this thread I will teach you every method I had to use to root any Spreadtrum devices, Starting with the riskless ones to the reckless ones.
I have to warn you that the last root method (using ResearchDownload to load a modified system.img) may be dangerous ! (because of possible partition table changes)
The others methods are pretty safe, don't be afraid by them if you do exactly what I wrote.
Theses processors are also named SP6820 and SP8810, it's exactly the same processor, it's just some misnaming from Chinese sellers.
Theses methods do work on the newest Spreadtrum CPUs, like the SC7710 (the 3G WCDMA model), and the more powerful SC8825/SC6825 (dual core).
Why buying a Spreadtrum based phone ?
They are really cheap, and they work amazingly well ! They can play some games and emulators very well, that's unexpected for such low end devices (50$ or less)
They usually only have 256MB of RAM but despite that, they still runs well ! (I tested a lot of games and some 3D games are working flawlessly, pretty amazing) - I discovered that they are using zram (or other swap methods) to provide more RAM by compressing it when needed. That's pretty neat and really helps with such a small amount of RAM !
They are very good as a portable multimedia device, to read mails, browsing the web, play some games, mp3, videos.
As a 2G phone they are competent, but the 2G modem is not as good as the one in MTK processors. (It takes longer to load something in the same conditions)
Boot very fast, and have decent battery life. (3-4 hours of video out of a 1200 mAh battery - 5-6 hours out of a 1800 mAh)
Why you should not ?
Not true anymore, but they were extremely difficult to root in some cases.
They don't seem to be well tested ... You can have a microphone so quiet nobody will be able to ear you. But it's easy to fix as you can see here: http://forum.xda-developers.com/showthread.php?p=38731407
They don't have any form of usable 3G support. (except the SC7710 who have WCDMA 850/2100 compatibility)
They usually have only 256MB of RAM again. So that can be a problem when you are, for example, using Opera Mobile Classic with more than 3 tabs. And make the transition between apps longer.
SC6820 and SC8810 model are all using Android 2.x, even if some are marketed as Android 4.0 phone (very big and blatant lie !)
They usually use android 2.3, but some are only Android 2.2 phones ! (The fake Android 4.0.3 for instance is usually only android 2.2)
SC6825 and SC8825 seems to only have a (real this time) Android 4.0.3 firmware. 4.1 are better is often advertised, but it's again ... lies ... Android 4.0 is not really suitable for phones with only 256 MB of RAM, so SC6825/8825 phones are pretty rough on the edges. Using more than one tab on the default web browser is asking for troubles for example.
They all use the MocorDroid Firmware. It's some kind of fork of Android that use NON-Standards and sometime buggy Launchers and they often use alternative keyboards like Go Keyboard which is kind of a bad choice considering the RAM and ROM constraints on theses devices ...
The only difference between the SC6820 and the SC8810 is the support for the Chinese form of 3G.
If you don't live in china, that means this two processors are essentially the same. (Don't trust sellers, the 8810 is NOT WCDMA "3G" compatible)
Some phones with the fake Android 4.0.3 based on 2.3.5 will brick themselves nearly 2 months after you first used it. It's a really weird behavior of this early Spreadtrum firmware. So if you have this firmware, just do whatever it takes to root it, make a backup and install CWM as soon as possible to be able to recover from this possible breakage. It's only a problem with a fraction of Spreadtrum phones, but you will be very happy if you have installed CWM before encountering it ^^ (applicable only if you bought one in 2012)
A lot of fakery in the Spreadtrum scene. For example fake MTK6515/MTK6572 phones that are in fact just SC6820/SC6825 phones with a firmware modified to lie its processor ID to populars android benchmarking tools like Antutu Benchmark.
If you are searching for a 512MB RAM phone, you'd better go for an MTK(6575/6572 or better) Phone. As you will never find a real 512MB Spreadtrum phone in the jungle of lies you are looking at ...
On all model with 2.3.5 based firmware (SC6820 and SC8810 essentially), you can have a lot of problems with the SIM card detection on some sim cards. For example I can't call somebody with mine, but I can answer a call or send/receive SMS ... Very weird bug ...
This bug seems to be related on the type a sim card you have. With some their is no problem at all.
I can confirm that it's working flawlessly on SC6825 and 8825 based phones with the real 4.0.3 based firmware.
Why rooting it ?
Because a lot of them come with a lot of sh*tty softwares, including the bad launcher and keyboard.
Because they can come with a "Virus" that can send SMS messages to china (so you have to pay for unwanted international SMS cost)
I myself have this Virus on one of my phones, as of now, I haven't noticed anything unusual. Just the useless, unkillable com.android.caivs.app process eating 15 MB of RAM doing nothing. (It is a significant waste of ram on such devices)
(As of now I only seen this malware on Feiteng devices - You can share your experience with this thing down bellow)
More about CAIVS here: http://web.archive.org/web/20110812021151/http://www.cseed.cn/chinese/news/portfolio2.htm
That virus was on most of the earliest Spreadtrum phones but don't seem to be a worry nowadays. But I haven't tried any new Feiteng devices. They were so poor in quality that I will never buy feiteng again so find it by yourselves if you feel adventurous xD
How-to do that ?!
If you are lucky you will be able to root your phone by traditional means.
If you are not, you can root them by manually adding the root utilities to the ROM.
I will describe every methods that you should try in order of difficulty and risks.
Before doing any of that, go to the android setting -> applications -> Development -> Check USB Debugging.
Universal Root utilities
Theses methods are safe, and the second one is, as of now, working on every Spreadtrum phones flawlessly !
1.1 - Z4Root
Just try z4root !
http://forum.xda-developers.com/showthread.php?t=833953
z4root is a little tool to root Android 2.2 and sometime work on 2.3
It's known to work on devices with the fake Android 4.0.3 based on 2.2 and MocorDroid 2.2.2
It may work on more of them, just try, there is no risks at all.
Make sure you have at least 50 MB of available space on the /data partition before trying this. (not the SDCard, the Applications Space)
Try a temporary root to see if it works, then you can do the permanent root.
You will maybe have to try it 2 or 3 times before it works.
Even if it doesn't work, reboot the phone after this. Because it can eat your battery while running in the backgroung if it fails.
1.2 - vRoot
vRoot is a chinese tool to root many devices !
It's proved to work very well with Spreadtrum (and MTK) devices. I used it successfully on a lot of Spreadtrum devices, even the most recent ones (SC8825).
You only need a Windows Computer (I personally use it on Windows 7 32bits).
Then download it from here: http://www.mgyun.com/en/getvroot
Install it and then open it.
As of now you only need to plug your USB cable to your computer, and then click on the Root button. (you don't need to do anything else, don't touch your phone)
Once it's done and the phone rebooted you will be rooted !
The root app is some kind of custom chinese one, but it's working properly.
Don't try to replace it with SuperSU as SuperSU don't seem to work properly on Spreadtrum devices.
If you want to understand what the root app is saying, try to set the language on your device to English.
2 - Custom Firmware Flash
Please never use any custom firmware available in .pac file format ! Or at least, don't use them before doing a full backup of your current firmware !
Feiteng A7100 (only if you have the mt6515_c910_ht_en_4.0_v01 rom/firmware on it !!! If not, don't touch it, you will end up with a brick ! Or screen reversed, or other strange bugs): http://forum.xda-developers.com/showthread.php?t=2149396
If you have a Feiteng A7100 I really recommend NOT TO USE this rom ! Why ? Because it only works on a fraction of A7100, newer releases of the same phone don't use the same firmware. With this tutorial here, you can root your A7100 easily and way safer. Please go to "4-" on this tutorial to know how to root your A7100.
If you append to find some others Custom roms for spreadtrum devices, or are making one, please send me a PM, I will link them here.
3 - Fastboot to the rescue !
If every fast, simple and secure methods are not working, then this will be difficult my friend !
3.1 - Find Fasboot
First, let check if we have fastboot in your phone !
Fastboot is a little tool inside the bootloader. It's here to help you flash the firmware.
Not every Spreatrum phones have it, so let's check if you are lucky !
You can access it by powering on the phone up while holding a key.
First power off your phone.
Then hold some button like volume+
while pressing this button, press and hold down the power button.
Keep holding the two buttons until the screen light up.
You should now have something on your screen. Maybe a system diagnostic tool (a menu with a set of system tests, that's totally useless) or maybe the recovery mode (a screen with a warning sign, and now your phone is stuck here until you pull out the battery) or, and that means victory, a screen that says "Fastboot".
If you are not on fastboot, but are on the Recovery or the System Test, turn the phone off again and try another button press at boot time exactly like I said before.
This time, try the Home button if you have one, or the Volume-.
You should also try buttons combinations. Like volume up and down at the same time. Home + vol Up, etc and maybe the 3 at the same time ...
(if you just boot as if nothing was pressed, you maybe have to unplug the battery, wait for a while and put it back before powering the phone on. Theses things are also not working when the usb/charging cable is plugged in - if some keys combinations are not doing anything, it's perfectly fine, it means they don't trigger any hidden boot mode)
If nothing bring fastboot up, you have to use the Spreadtrum Debug tool "ResearchDownload" ...
So Skip to "4-" ! ^^
3.2 - Install the drivers
If you append to find Fastboot, we will have to install the PC part of it !
Like every android phone, you have to install adb and his drivers to access the Android Debug Bridge.
You can find them and learn how they work here: http://dottech.org/21534/how-to-ins...ows-computer-for-use-with-your-android-phone/
On Ubuntu or Debian Linux you just have to install them that way:
Code:
sudo apt-get install android-tools-adb android-tools-fastboot
You also have to install the phone drivers if you are using Windows:
ADB Drivers: http://www.mediafire.com/download.php?c5nf3rlhxmxhu4x
Debug Drivers: http://www.mediafire.com/download.php?2tyg0k2xp3ejgyg
Mirror: http://www.mediafire.com/?o9km8vl287ev24j
Then you will have to tell adb what phone to use. By that I mean adding the PCI ID to a text file to tell adb that this peripheral is compatible.
The Spreadtrum PCI ID is 0x1782
add this line to "Your user directory/.android/adb_usb.ini"
Code:
0x1782
3.3 - Using fastboot to load CWM (Clockwork Mod)
CWM work on some of theses Spreadtrum devices, most of the time, the screen is reversed, but it works !
On some phone, you will be presented with a blank screen, but CWM will work ... That will just be very difficult to navigate ... (don't bother and use another method if you append to be in this boat)
Here are the recovery images available for Spreadtrum device to my knowledge:
* http://www.mediafire.com/download.php?u6uyignmdcpillt - extracted from a random SC6820 that I don't remember
* http://www.mediafire.com/download.php?bosnfcq9n65mtc5 - i9270+
* http://www.mediafire.com/download.php?xem49dy5dh99ml0 - 5830, S5830, Q5830, Q206 and GT-N9300 (maybe more)
* http://www.mediafire.com/download.php?adfwq6b5268qb58 - S9300 (SC6820A S3 Clone)
* http://www.mediafire.com/download.php?y2f7aaan4b00l1m - Feiteng GT-A7100 and probably more Feiteng devices.
* http://www.mediafire.com/download.php?lg7m6v49efzpnjk - 6500-TV or S560
* http://www.mediafire.com/download.php?6xn977jjsuusjan - N9300 (I9300 Clone)
* http://www.mediafire.com/download.php?d68wc334qn47tdd - S930 or N8820
If your device is not listed or the one for your device doesn't work, try them all, even if your phone is SC6820 and the recovery was made for SC8810, if none are working, we will have to flash the entire system partition, which is a lot more difficult and dangerous ...
Flashing CWM to the phone:
Linux Only: Initialize ADB:
Code:
sudo adb kill-server
sudo adb start-server
Boot your phone in fastboot mode.
Be sure your device shows up:
Code:
fastboot devices
if your device show up, it's time to flash
Code:
fastboot flash recovery recovery.img
It's flashed ! Let's reboot now.
Code:
fastboot reboot
Start on CWM, if it works, you can start to root the phone !
Download this patch: http://www.mediafire.com/download.php?131nsw87afzwb5v
Put it on the root of your SD Card.
Now you will have to boot on CWM, he is on the same key combination than the old useless recovery was. (Most of the time Volume- and Power)
You can also try this command with adb:
Code:
adb reboot recovery
Now it's the perfect time to do a full backup of your firmware with CWM, so please do so, that can come in handy. (please go to the end of this tutorial after rooting your phone to know how to make a FULL backup. CWM will only make a partial one.)
choose apply update.zip
Choose the file you have put on your sd card before
Apply it then reboot.
This update.zip have pushed everything needed to root your phone in the right place, you should be rooted now !
If you have an error like:"Can't mount /sdcard" you may have to try with another SD Card and be sure your SD Card if formated as Fat32.
3.4 - Using Fastboot to load a modified system partition image
Please follow the instructions down bellow on how to "5 - Create a rooted system partition image"
When you have done your Rooted system partition image, flash it like that:
Code:
sudo fastboot devices
#if your device show up, it's time to flash
Code:
sudo fastboot flash system system.img
#It's flashed ... Now let's reboot with all the apprehension of the world
Code:
sudo fastboot reboot
If it boots (should boot), you will be up and rooting !
4 - Spreadtrum ResearchDownload tool to the rescue !
First, if you have fastboot, use fastboot ! It's simple, more reliable, faster. It's bottomline better !
If you don't have fastboot or can't figure out how to bring him up on your phone despite trying for about an hour. This tool will most likely work.
First, you should use Windows XP 32bits. Even real XP or in virtualbox.
It might work on windows 7 32 bits and 64 bits but you will have to tweak the system to allow installation of non signed devices drivers ...
ResearchDownload work as this:
First you start the Channelserver - This thing is here to make a bridge between the tools and the driver.
Then you start ResearchDownload.
Now you can make a full firmware flash (you should not !! It's a terrible idea !) or flash a single partition. But to do that, unfortunately, you should have a compatible set of fdl files.
Finding them on google is impossible, you have to extract them from your full firmware .pac file.
If you can't find your firmware on the Internet, you will have to try every single one you can find from others firmwares. I gathered all the fdl files I could find in a single package, so it won't be that difficult.
It's highly probable that you will find one that will work with your phone. This thing have to boot the phone and flash the Nand Flash chip. I'm pretty sure there is not a lot of different ways to do this on a single processor.
I really don't know the risks of using a wrong fdl set. But we haven't seen any risks at all yet. Some will work on your phone, others will just do nothing. You will just have to try every single one until one work.
I named the folders with the names of the phones I know working with theses. So it will be easier to find the good one. (A7100, 6500-TV, 5830, Q206 and S930 users will feel very lucky ^^)
4.1 - Learn how ResearchDownload Work
First you have to install the drivers, you can find them here:
ADB Drivers: http://www.mediafire.com/download.php?c5nf3rlhxmxhu4x
Debug Drivers: http://www.mediafire.com/download.php?2tyg0k2xp3ejgyg
Then you have to plug your phone to your computer with your micro usb cable. Your phone have to be powered on.
Be sure every pieces of hardware are detected and installed correctly.
As you can see, this phone is not just detected as an ADB device, or as a mass storage device.
It actually have an internal serial port to usb adapter !
In other words that means this processor provide a way to flash his nand very easily even if it is fully bricked. It's a rare and pretty good feature you don't see that often. In fact, most of the time you have to solder a real serial port yourself on the phone motherboard, then have to use a Serial to USB adapter to have this level of access to the hardware.
So yes, back to tutorial.
Now you will have to unplug your phone and turn it off.
You have to download the debug tools, you can download them here: http://www.mediafire.com/download.php?rngukh111vqfr8h
First you have to start the channel server, you will have to disable your firewall for this app, it's because this tool use a network protocol to communicate with the other tools.
Then open ResearchDownload.
ResearchDownload is a weird flashing utility, it can open a .pac firmware file and can make a .pac out of .img files. You also can flash .img files and that's what we will do. But unfortunately it can't make a full backup ... So be careful !
The cog logo is here to let you open a .pac file. We don't need that as we probably don't have it.
The "two cogs logo" let you configure the flash utility.
Click on this to bring a new window.
On the download settings window, click on select product then choose your type of phone. (SC8810 or SC6820, it doesn't really matters if you take the wrong one out of those two.)
Then uncheck "Select All Files" as you don't have any of theses.
You can see FDL1 and FDL2 are still checked, and you don't have those files ...
As they are needed to start the Flash utility, we will have to find them.
I came across only 3 different FDL1 files, but for theses FDL1 it seems every phone have his own FDL2.
You will have to find the ones that work for you.
Here is an archive of nearly every FDLs available: http://www.mediafire.com/download.php?c6q2gxobccv32oj
Choose one FDL1, and one FDL2 located in the same folder. (you can choose a File with a right click on the FileName blank space in front of FDL1)
Click on OK.
Then click on the "Play button" saying start download.
It may show some warning, it's not a problem.
Now, press Volume Down on your phone, then you have to plug it on the USB Port, still holding the button.
You can release the button when the flash begins.
You may have to press an other button than Volume-. Some phones are reported to use the Home Button instead.
You may also have to remove, wait a while, and reinsert the battery before holding volume- or after the flashing procedure to be able to start the phone.
If ResearchDownload shows you an error or timeout, try another set of FDLs Files. Keep trying until you find one pair that work !
If it works the flashing process should start right away. Just a millisecond after Windows have detected and initialized the device when you plugged it.
When you have the right FDLs, you can go to the next step, flashing something useful ^^ (we haven't flashed anything as of now, just been searching for a compatible flashing bios)
If your working FDLs folder does not have the name of your phone, please tell me what phone you have and what FDLs you used so I can rename them.
4.2 - Using ResearchDownload to load CWM (Clockwork Mod)
Do exactly as said before, but check the "Recovery" checkbox on Download Settings. and choose one of theses CWM images:
* http://www.mediafire.com/download.php?y2f7aaan4b00l1m - Feiteng GT-A7100 and probably more Feiteng devices.
* http://www.mediafire.com/download.php?lg7m6v49efzpnjk - 6500-TV or S560
* http://www.mediafire.com/download.php?6xn977jjsuusjan - N9300 (I9300 Clone)
* http://www.mediafire.com/download.php?d68wc334qn47tdd - S930 or N8820
* http://www.mediafire.com/download.php?xem49dy5dh99ml0 - 5830, S5830, Q5830, Q206 and GT-N9300 (maybe more)
* http://www.mediafire.com/download.php?bdl1qr7orsj4ebr - extracted from a random SC6820 that I don't remember
* http://www.mediafire.com/download.php?6g1t6057p6c8wpt - i9720+
* http://www.mediafire.com/download.php?adfwq6b5268qb58 - S9300 (SC6820A S3 Clone)
When you flashed one successfully, try to boot on recovery (Usually by holding Volume- while holding the power button until the screen light up).
If your device is not listed or the one for your device doesn't work, try them all, even if your phone is SC6820 and the recovery was made for SC8810, if none are working, we will have to flash the entire system partition, which is a lot more difficult and dangerous ...
Download this patch: http://www.mediafire.com/download.php?131nsw87afzwb5v
Put it on the root of your SD Card.
Now you will have to boot on CWM, remember, he is on the same key combination than the old useless recovery was.
You can also try this command with adb:
Code:
adb reboot recovery
Now it's the perfect time to do a full backup of your firmware with CWM, so please do so, that can come in handy. (please go to the end of this tutorial after rooting your phone to know how to make a FULL backup. CWM will only make a partial one.)
choose apply update.zip
Choose the file you have put on your sd card before
Apply it then reboot.
This update.zip have pushed everything needed to root your phone in the right place, you should be rooted now !
If you have an error like:"Can't mount /sdcard" you may have to try with another SD Card and be sure your SD Card if formated as Fat32.
4.3 - Using ResearchDownload to load a modified system partition image
Now we are in deep **** ! This can be tedious ... You will need to drink a lot of coffee, then you will probably pull your hair off, but it's possible to root every single Spreadtrum devices this way !
Please follow the instructions down bellow on how to "5 - Create a rooted system partition image"
When you have done your Rooted system partition image, reboot on Windows, then flash it like that:
Do exactly as said on the paragraph on how ResearchDownload works, but check the "System" checkbox on Download Settings, and choose your modified system.img file to flash it on the device.
As it is still not tested at all, you will have to pray some kind of Spreadtrum God and hope it will be successful ...
The first boot after the flash can be very VERY long. It's perfectly normal.
After the flash is done, please make a full backup (see bellow how you can do that), so I can make a Clockwork recovery partition working with your phone.
You may need to flush your data partition with CWM to avoid some crazy bugs after the flash. You will have theses bugs because of the partitions realignment that might occurs as a result of using a slightly different FDL set as the manufacturer.
Don't even try to do a factory settings reset before installing CWM, as I don't know what monster can lie ahead if you do a factory reset without any working recovery installed
(If your phone doesn't boot after the flash, it is possible to flush the data and cache partition with ResearchDownload. I will explain it, if needed !)
5 - Create a rooted system partition image
Please always try the CWM method first ! There is no risks at all to destroy your phone if the recovery is not working. Here we are making a new system image to flash on the system partition, this partition contain the Android operating system. I will try to explain everything as good as I can, but if you make a mistake, if you don't read my warnings, you can brick your phone very easily !
That will be difficult ... And you will have to use a Linux computer, or Linux in Virtualbox, or in a Live CD, basically you will need Linux somewhere on your computer ^^
Why ? Because we will have to preserve unix permissions on an extracted tar archive ! Trust me, you will probably brick your phone if you do that on windows ...
#Install ADB
Code:
sudo apt-get install android-tools-adb android-tools-fastboot
#Configure ADB
Code:
mkdir ~/.android
Code:
echo 0x1782 > ~/.android/adb_usb.ini
#Start the ADB server
Code:
sudo adb kill-server
sudo adb start-server
#Just let's check just in case if your device is already rooted
Code:
adb shell su -c id
Possible answers:
uid = 0 (root) gid = 0 (root) - your phone is already rooted ! (if you haven't noticed it, it's because superuser.apk is not installed, so just push it and install it via ADB and you are rooted !)
SU: Permission denied - You are not rooted ... Good luck then !
#Now we will backup the system partition !
Code:
adb shell tar -cf /mnt/sdcard/system.tar system
Please pay attention to the errors !
There will be missing files, and we will have to add theses by ourselves after the backup to pretend to have a full backup.
Here is the archive for the known missing files: http://www.mediafire.com/download.php?fm1z5ujc75bg268
If you have more than theses:
Code:
tar: can not open 'system/etc/dbus.conf': Permission denied
tar: can not open 'system/etc/bluetooth/audio.conf': Permission denied
tar: can not open 'system/etc/bluetooth/auto_pairing.conf': Permission denied
tar: can not open 'system/etc/bluetooth/input.conf': Permission denied
tar: can not open 'system/etc/bluetooth/main.conf': Permission denied
tar: system/lost+found: Permission denied
tar: Error exit delayed from previous errors
Then you should just give up, or tell me so I can send you the missing files.
Note: Lost+found is not important, it's just a folder automatically created by Linux to collect any corrupt files.
#Now we will pull this nearly full backup to our computer. Please keep it preciously somewhere secure.
Code:
adb pull /mnt/sdcard/system.tar
#Warning, theses next steps have to be made ONLY on Linux on an ext2/3/4 partition ! Please never attempts to do this on Windows or On Linux on a FAT32 partition.
#untar the archive
Code:
sudo tar -xvpf system.tar
#now we will restore the files we have not been able to backup.
#Download this archive if you haven't done this before: http://www.mediafire.com/download.php?fm1z5ujc75bg268
#Then extract it on the same folder as you extracted your system.tar file with this command:
Code:
sudo tar -xvpf btdbus.tar
#Now it's time to add the root utilities, you can download them from here: http://www.mediafire.com/download.php?v69nm172heos17o
Code:
sudo tar -xvpf root.tar
sudo cp Superuser.apk system/app/Superuser.apk
sudo install -m 06755 su system/xbin/su
#Now we will get rid of this virus ! (the file name can be something else. Like caivs.apk, or some random numbers at the end)
Code:
sudo rm system/app/eyuSales_20121116.apk
#And now you will have to make a flashable system image with this tool, included in the root.tar archive
Code:
sudo ./mkyaffs system system.img
#Now you can reboot your phone in fastboot or use researchdownload to flash your new System image.
6 - Do a full nand backup
Here is how to do a full nand backup of your beloved Spreadtrum: http://forum.xda-developers.com/showthread.php?p=39270468
7 - Don't forget to remove to caivs Virus
When you are rooted, you can remove the Virus or any preinstalled apps using Link2SD.
I suggest you to remove everything you have preinstalled if it is available on the Google Play Store (except the keyboard or the launcher !!!). For example if you have an old version of ES File Explorer on your phone preventing you from updating it, you can remove it safely, then install the updated version from the the Play Store.
Never try to remove something that you don't know what it is !
For the Launcher or keyboard. You can remove them only if you installed a new one on the System partition and tested it successfully !

Data missing?
First of all, thanks a lot for tutorial! Unluckily there is missing the data that i should copy back into the tar and then the img-file. Could you upload the btdbus.tar and the root.tar?
Thanks again, have a nice day!

I'll try to load CWM even though at the moment I can only get into recovery. I have the exact same model as H_Bler's which is why I've been focusing more on his thread. From your description on how to access fastboot, I assume that it's the diagnostic mode when UpVol + Pwr is pressed. I never saw anything that said fastboot. The only thing unusual when I was going through the menus was I always got an error when I try the 4th or 5th option. Unfortunately, I can't really try it again because I can't access it anymore. That goes without saying the I can't work with IMG files as well.

Well the thing you have when you push up and power is the system test menu. It's located on the android system partition. It's not fastboot.
Fastboot should be something that says "Fastboot" in red letter, or something else unusual.
If you have not fastboot you should use Spreadtrum Researchdownload to flash your phone, I will write the tutorial about it soon.
I really can't link you the thread on the russian forum, first because it will probably confuse you, and also because it's spread everywhere on so many threads it's unbelievable ... That's why I'm doing this centralization work for you ^^
I will post a list of ROMS for recovery purpose. Your phone seem to be bricked. I don't know how you've done it (I really want to know what you phone is and how you've bricked it, that will help me to write the warnings necessary to avoid such cases).
I have 14 roms for Spreadtrum devices, maybe one will work for your phone.
I just want to know what your phone is ^^ Please tell the name of your phone on your posts everyone and if you know how to find it, the exact name of your firmware.
PS: I will upload the patch soon, I'm just searching for a file hosting service that will keep it up and not erasing it 2 hours after I uploaded it ^^
EDIT: Link to the update.zip for rooting you device via CWM added.
Tutorial updated: Spreadtrum debug tools method added.
It may now be possible to root even Spreadtrum devices without Fastboot mode available.
Please feel free to tell me if it works !

Question
Dear Spreadtrum Master!
Please, can you help me with this problem:
I have a Star I8160 phone with Spreadtrum 6820 and 256 MB ROM. It seems, that everything is working fine, the ROM and the phone is fast, and cool. But when i try to use the phone as a phone, i talk to the phone, and the others just only hearing pieces of my sentences. Sometimes the phone is very-very silent, i need to shout for the others to hear. I thought, that this is a microphone problem, so i replaced the microphone. But nothing changed. I had 2 phones from this type, and both produces the same fault, so i think maybe the problem will be with the ROM. What do you think, is it possible? If so, can i replace my normal rom, which is DM_BASE_12A_w12.43 (sc6820_modem) 11-02-2012?
question
Hi ElectronikHeart, i need help
I have a feiteng a7100, and i flash a rom with ResearchDownload.exe, in the flash operations tab i choose the option to erase all flash. Now i have a brick phone. Do you have a copy of nv.bin? Do you know how to recover from it? how can i reflash nand?
thanks

The Master hasn't been in the past few days so I'll try to answer your issue as best I can.
Usually, the phones are designed for a specific region/country. It's possible that your ROM was built for a different one. How sure are you that the ROM which you are replacing it with will work for you? (I assume that you have a backup and you know how to load ROMs) Also, you might want to try editing the build.prop it increase/maximize reception.
To be honest, this is actually a complicated approach. From what you said, it seems that you've made other troubleshooting steps on your own. Since you really did not mention all of them I'm basing my response on what you said.
Let's try to stick to the basics first. Why did you replace the microphone in the first place? If the same issue happens with 2 other phones from this type, I don't think the mic is the problem. Also, does this mean that you can hear them fine, but they have a hard time hearing you? Have you tried using the stock sound recorder on your phone? Is it also choppy? Have you tried using Skype? You don't really have to call anyone, you just need to make a test call.
When using the device as a phone (eg. making calls, sending SMS, MMS, or connecting to the internet using EDGE or 3G), you're actually relying mostly on your carrier/service provider. How many signal bars do you get? The easiest way to test signal related issues would be by using a different SIM or using a different phone. (When you try a different phone, I suggest using a GSM one - the ones that can only make calls or do SMS.) It's highly possible that there's already something wrong with your SIM.

When you say brick, does it mean that you don't even have recovery mode? If you don't, try to see if you can put CWM. Once successful, you can try to use the A7100 ROM if your original one was a mt6515_c910_ht_en_4.0_v01 rom using the update.zip

The Master hasn't been in the past few days so I'll try to answer your issue as best I can.
Usually, the phones are designed for a specific region/country. It's possible that your ROM was built for a different one. How sure are you that the ROM which you are replacing it with will work for you? (I assume that you have a backup and you know how to load ROMs) Also, you might want to try editing the build.prop it increase/maximize reception.
To be honest, this is actually a complicated approach. From what you said, it seems that you've made other troubleshooting steps on your own. Since you really did not mention all of them I'm basing my response on what you said.
Let's try to stick to the basics first. Why did you replace the microphone in the first place? If the same issue happens with 2 other phones from this type, I don't think the mic is the problem. Also, does this mean that you can hear them fine, but they have a hard time hearing you? Have you tried using the stock sound recorder on your phone? Is it also choppy? Have you tried using Skype? You don't really have to call anyone, you just need to make a test call.
When using the device as a phone (eg. making calls, sending SMS, MMS, or connecting to the internet using EDGE or 3G), you're actually relying mostly on your carrier/service provider. How many signal bars do you get? The easiest way to test signal related issues would be by using a different SIM or using a different phone. (When you try a different phone, I suggest using a GSM one - the ones that can only make calls or do SMS.) It's highly possible that there's already something wrong with your SIM.

Dear Spreadtrum Master!
Please, can you help me with this problem:
I have a Star I8160 phone with Spreadtrum 6820 and 256 MB ROM. It seems, that everything is working fine, the ROM and the phone is fast, and cool. But when i try to use the phone as a phone, i talk to the phone, and the others just only hearing pieces of my sentences. Sometimes the phone is very-very silent, i need to shout for the others to hear. I thought, that this is a microphone problem, so i replaced the microphone. But nothing changed. I had 2 phones from this type, and both produces the same fault, so i think maybe the problem will be with the ROM. What do you think, is it possible? If so, can i replace my normal rom, which is DM_BASE_12A_w12.43 (sc6820_modem) 11-02-2012?

Hi,
I had the same problem with one of mine. You just have to use a diagnostic tool from Spreadtrum and adjust the microphone amplification level. I will start a thread on that subject and link it there.
It seems to be a very common problem with Spreadtrum phones, but it is, most of the time, very easy to fix.
edit: here is the link: http://forum.xda-developers.com/showthread.php?p=38731407
WARNING: Don't ever flash if you don't have a working copy of the original firmware somewhere (a complete backup that you have tested your ability to flash back) The first step to do a complete backup, if the manufacturer don't want to send you the firmware, is to successfully root your firmware)
Don't flash if you have a microphone problem, nothing good will happen, this problem is not firmware related AT ALL.

Hi ElectronikHeart, i need help
I have a feiteng a7100, and i flash a rom with ResearchDownload.exe, in the flash operations tab i choose the option to erase all flash. Now i have a brick phone. Do you have a copy of nv.bin? Do you know how to recover from it? how can i reflash nand?
thanks

Oh god ! Why have you checked that option ^^
I may be able to dump my nv.bin file from the a7100 I just bought. (If I recall correctly, the nv.bin contain the imei so I will have to edit it to use your imei instead, imei are written in the battery compartment)
Can you try flashing it a second time entirely, It's possible that your uboot partition (what manage the early time boot operations), is not flashed properly.
Even without the nv partition you phone should be able to boot android, you will just not be able to use the phone as a phone. (make a call and everything)
Try with a better micro usb cable, Chinese ones can be very cheap and corrupt data on the way to the phone.
If your phone is still able to flash using ReasearchDownload that is.

Please if you have rooted your phone using this method, and can't use the CWM method, that mean I can do a CWM that work on your device !
Now that you are rooted, you can make a full backup of your phone with ADB !
#open adb shell:
Code:
adb shell
Code:
I still have to explain this if someone needs it
Then send me you boot.img file and I will send you a recovery.img that you can flash to your recovery partition.
That will help new users to root a lot faster the same phone as you, and will make your life easier is you have to restore a backup.

So, you already have tested every recovery already posted ?
To make a backup of your boot.img, you will have to do a full backup manually using the Android shell. I will make a tutorial about this, and link it here.
It's pretty easy as you already rooted your phone.
When you have your backup I will, post a recovery.img file suitable to your phone.
Please keep an eye to this post. I will post the tutorial very soon.

I just bought my A7100, so you will need to wait 2 weeks for me to dump it. Maybe you should try asking to the guy who have made the rooted rom for the A7100 ?
I will, none the less, make a full backup of my phone as soon as I receive it.
Hello everyone.
You should know that time ago Motorola decided to stop updating our Xoom, but we showed (and we are still showing) them that our tablet is still alive and kicking.
Let me update this with the last news (a big win, indeed) from @bigrushdog:
IMPORTANT: It should be harmless for your Xoom, but you need to do it at your own risk. Nobody will give you any kind of warranty and we will be not guilty if your Xoom bricks, dies, loses the data, gets cursed, your cow starts to give bitter milk or if it unchains a thermonuclear war.

BigPart Repartition Upgrade and Resource Center
Credits
Much love, credit, and respect go out to @Schischu and @rchtk! Your insight on the kernel patch paved the way! The Motorola Xoom cheats death once again!
Repartition Guide
1) Your data will be totally wiped! If you have Nandroids, TitaniumBackups, or anything of any value on your internal storage, copy them to your microsd or computer! They will be gone forever! Your microsd card is the only safe haven on your Xoom during this process.
2) Put all needed resources on your microsd card! You will need the original TWRP 2.6.3.0 touch recovery from @runandhide05, TWRP 2.6.3.0 BigPart version, your desired rom, and the BigPart boot image that goes with your desired rom. The BigPart boot images can be found in the next section.
3) Reboot into recovery. Flash TWRP BigPart. Don't reboot just yet.
4) Go back into wipe menu and wipe everything but /sdcard.
5) Go to reboot menu and reboot into recovery. Disregard the "No OS" warning and don't install SuperSU when asked.
6) When you come back into recovery, it will think your data is encrypted but it's not. Go into wipe menu and "format data". Type "yes" when prompted. When done, go back into wipe menu. Select "Advanced Wipe". Check "system" and "cache" and wipe them.
7) Hit Home then go to reboot menu and reboot recovery. Once again, disregard "No OS" warning and don't install SuperSU when asked
8) When you come back into recovery, go into mount menu. You should see "cache" and "data" checked. "System" will be unchecked. Check it to confirm it mounts, then uncheck it. Congratulations! You are now repartitioned!
9) Go into install. Recovery should show your microsd storage by default. If not, using the navigation panel, navigate to root then go into "sdcard". Flash your rom, BigPart boot image package, and any other resources as you normally would.
10) Reboot into system. You are done!

Q&A
Q: OK to understand this right, now we have a new recovery and boot. Which ROM do we use? The same as before? And BigPart @dreamcwli MyWingray 4.3 is only for wingray?
A: Yes, we have new recovery and boot. For this recovery and boot you need to use the new BigPart roms. If you are not using BigPart roms, you will need to install old recovery and boot and format everything again. And yes, it seems like @dreamcwli MyWingray 4.3 is only for wingray at the moment, but brd published a version of the last EOS4 stable with the new kernel working for BigPart.
Q: Does this new space mean we can start using full blown GApps Instead of the scaled down versions we had been previously?
(I understand there may be NEON ramifications causing a NO Answer here)
A: You can use the GApps that you prefer. Now we have space enough, but scaled down versions might be slightly faster as it uses less resources (I guess).
Q: Seems like a good time to ask and reveal my limited understanding of why user space is formatted vfat. I'm a linux fan who dislikes being limited to 4096 Mb when creating a linux.img. A yes or no answer will suffice. As long as the devs are pushing the limits, can the user space (sdcard) be formatted ext2, 3 or 4?
A: I think that that is something to implement in the kernel. I think that it is easy to do and our bakers eventually will implement it.
Q: Can cm10.2 be flashed instead of an eos4 rom after the repartition?
A: You need to replace BOOT.img in the CM zip with the BigPart compatible with your Xoom, and if the kernel is compatible with CM it will work.
Q: I'm on stingray_cdma.....unless i can flash a wingray rom and boot.img after the repart?
A: No idea, but it's safer to use roms build for your device. Take a look to the previous question.
Q: im on stingray and i tried using cm10.1 as my rom and it didnt get to the bootanimation so i tried eos 3 and it works well. couldnt get eos 4 to download from goo.im
A: brd published some EOS4 working with BigPart (see http://forum.xda-developers.com/showpost.php?p=47005701&postcount=1 )
Q: I am asking again to understand this right, now we have a new recovery and boot.
Which ROM do we use? The same as before? Do we have to change the boot IMG in the ROM with the big part one?
And BigPart @dreamcwli MyWingray 4.3 is only for wingray or it can be used with everest as well? And what is its difference with the other big part in the kernel?
A: Use only BigPart roms. You will need to change the boot.img from the rom if the rom is not compatible with BigParts, but if the rom is not compatible with the new kernel, it is useless... MyWingray is compatible with Everest but you will not have 3G, I guess... But I'm not sure.
Q: That's great. @bigrushdog @realjumy Is there a way to get the radios for everest and stingray on a separate zip?
A: The rom must be cooked with the radios...
Q: I wanna ask you because i have my xoom forma two years, and laste time i format it and give me error with dev block mmblck or something else and i think that i could have my internal storage corrupt.. If i install your 4.3 image modded, and then the repartition, Will it works fine?? Thanks and sorry me
A: No idea.
Q: Followed the instructions for the re-partitioning. Everything worked except the Xoom cannot see the external sd card in recovery. I have re-formated it as fat32 and tried another card. When I view the files in the PC they are there. Any ideas?
A: Something something went wrong... Copy the data from the SD to your PC, format SD and put back data. Let's see if that works...
Q: How can we identify which ROMs are for the new partition layout? Just assume everything 4.3 and later? It would be nice if we added [BigPart] to the thread title to make them more easily identifiable.
A: Only roms with BigPart in their name can be used with the new layout.
Q: I was under the impression that we could use old roms provided we replaced the boot.img in the zip with the NEW BIGPART boot.img for our unit? (Only after repartitioning has been completed) Is that wrong and we need to wait for a particular build?
A: Not all the roms are compatibles with the boot.img method (kernel method). You will need to try to be sure. EOS4 and Dream's have proper versions. If you want to use, for example, CM you will need to:
option 1.- Build it yourself patching the kernel
option 2.- Use CM and try to use a different kernel
option 3.- Ask to the CM maintainer to release BigPartition versions.
There is a lot of 4.2.2 projects running, some 4.3 and if we are successful, MAYBE we will be able to port 4.4 to our devices. One of the main problems (but not the only one) is the internal storage structure of the tablet. It seems that is not too hard to solve, as in other devices (mainly Samsung) is common to change it.
The aim of this project is to compare how the internal partitions are setted up in order to change them and have more room for system and apps. This will improve all the ROMS (4.1, 4.2.*, 4.4). @bigrushdog is doing a big effort to change it but we need more data from all models to compare and be sure that we don't break anything.
It will take up to 3 hours (depends on the model) but is something that can work while you are sleeping or not using the tablet. With the data provided by you, we can compare and choose the best changes.
IMPORTANT: It should be harmless for your Xoom, but you need to do it at your own risk. Nobody will give you any kind of warranty and we will be not guilty if your Xoom bricks, dies, loses the data, gets cursed, makes your cow begin to give bitter milk or if it unchains a thermonuclear war.

What are you going to do:
You are going to do a 1:1 copy of your internal storage into your PC. Then, we will detect the partitions and where begins and ends each one. Nothing else. We will compare the different versions and in the future a tool will be released to make the changes.
What you will need:
Linux (maybe you can use a Live DVD / USB?). It should be a way to do this process under Windows. If you know how to do it, please, share the info.
33GB of disk space in your computer, anywhere.
Android SDK working (that means that if you plug your tablet turned on and run
Code:
./adb devices
in the folder "platform-tools" of your SDK will provide a serial number): http://developer.android.com/sdk/index.html
3 hours (can be done while sleeping, not using the tablet, etc) if you have a 32GB Xoom.
Rooted Xoom.
Before you begin:
DO A NANDROID BACKUP!!!!!
READ EVERYTHING AND ASK IF YOU DON'T UNDERSTAND SOMETHING
Step by step:
Full charge your tablet (or keep it connected to AC?) and turn it on WITHOUT SDCARD.
If your Android SDK is not installed or working properly, fix it now: http://developer.android.com/sdk/index.html
Install the dependencies. For Ubuntu / LinuxMint / Debian:
Code:
apt-get install testdisk netcat pv extundelete testdisk
Activate USB Debug on your device (in order to connect with adb). You can find it under Settings > Developer options.
Note: On Android 4.2 and newer, Developer options is hidden by default. To make it available, go to Settings > About phone and tap Build number seven times. Return to the previous screen to find Developer options.

Plug your tablet (it must be on) and run
Code:
./adb devices
in the folder "platform-tools" of your SDK. If you don't get as a result a serial number, STOP. Something is wrong with your SDK. Please, fix it to continue.
Open a terminal on your computer, go to the Android SDK directory's subdirectory sdk/platform-tools (where adb is located).
We will setup a forward port to be able to download the data to our PC:
Code:
./adb forward tcp:5555 tcp:5555
Now we will connect to the tablet
Code:
./adb shell
Maybe you need to grant permission to do it. Take a look to your tablet's screen.
We become superuser:
Code:
su
Grant permanent permissions when asked. You can revoke the permissions later if you want.
With this we will transfer the data to the port that we set previously:
Code:
/system/xbin/busybox nc -l -p 5555 -e /system/xbin/busybox dd if=/dev/block/mmcblk0
DON'T CLOSE THAT TERMINAL. An now OPEN A NEW ONE IN THE PC.
Go again to the folder "platform-tools" of your SDK and let's collect the data:
Code:
./adb forward tcp:5555 tcp:5555
Code:
nc 127.0.0.1 5555 | pv -i 0.5 > mmcblk0.raw
If you want to save the file in a different place/partition, change what is after ">". For example, if I want to save the file in my home folder, I will write /home/jumy/mmcblk0.raw. If you are not sure or don't know how to do it, don't change it.
You will to wait up to 3 hours until it finish.
When the transfer is finished, run this in the folder where the dump is located (if you changed nothing, it is located in the older "platform-tools" of your SDK):
Code:
testdisk mmcblk0.raw
First restore the GPT partition table. Select mmcblk0.raw in the TestDisk interface and choose Proceed.
Choose EFI GPT.
Then select Analyse.
Choose Quick Search.
The search will return a table that you should copy and paste in this thread.
Now you can exit and remove the dumped file (mmcblk0.raw).
Please, when you provide the data, tell us which model, storage size, ROM name and version and indicate if it is the Hong Kong model.

4.4 will have the same problem that 4.2.* and 4.3 as it is a problem with the storage. That is the reason why we need so badly to change the partitions, and that is why we are asking for help to collect this data.

notbrodie, there may be something wrong in your experiment as the dump file is only around 2GB. Or maybe you just have non-standard partitioning, I am not sure...

- closing code tag seems to be lost in ./adb shell command

I'm dumping stingray right now. From what i can see, it already looks like the offsets are different for different models. That's very good to know. So calculations will need to be made for each version. After talking with @Roach2010 he says there may be partition table info that needs updating somewhere in the NAND dump. However, it doesn't appear that is the case for all devices. Once i get this dump we can play some more.
EDIT: found some interesting information http://forum.xda-developers.com/showthread.php?t=1388996

I have a mz605 umt_everest model, at monday in my lab I will do this and post here.

I'm dumping stingray right now. From what i can see, it already looks like the offsets are different for different models. That's very good to know. So calculations will need to be made for each version. After talking with @Roach2010 he says there may be partition table info that needs updating somewhere in the NAND dump. However, it doesn't appear that is the case for all devices. Once i get this dump we can play some more.
EDIT: found some interesting information http://forum.xda-developers.com/showthread.php?t=1388996

Nice find, so by doing this research and analysis it will be possible to create a universal partition structure (in terms of the XOOM versions). am i right in thinking this?

No... Whit this we will be able to:
1.- Check if every Xoom version have the same or different partition structure (done, each model has a different structure).
2.- See how every model need to be restructured (pending, that will be next step).
3.- Provide a script to make it easy to do (we need to do the 2nd step first).

hi!
i installed the regulat 1.6 update to my FP1 and everything was just fine.
then I tried to install the "unified 1.6 update" which worked but the problems begun:
things I noticed:
1. backup ist not really a backup for the apps but just a way to reinstall the apps I had installed without any settings. not a fun way to find that out when reopening your apps.
2. the update to the 1.6 unifyed also messed with my SD card and deleted files and put new ones there. not something I was expecting. luckily I had a backup of the SD card.
the thing I am looking for a solution:
after merging the partitions I cannot acces the phone storage on my PC (mac osx 10.9.4). not directly as a drive. the android fil transfer tool works, but it does not have all abilities finder/explorere provides. how do I get acces to the phone storage again?
As all my settings are gone anyway I am open to reinstall the phone from scratch.

Because of the partition layout it no longer is possible to expose the internal storage as mass storage device. Adb will work but the preferred way of transferring files is using the MTP protocol.
I am not a mac user but I think you need to install some additional software.

thanks a lot, that is what I feared.
hi, i'm also have an upgrade problem: mine is that i can't upgrade at all.
i've repartitioned earlier with the app mentioned in the wiki (wiki/Fairphone_Fairphone/Guides#How_to_partition_your_Fairphone).
i've also done the steps _keesj descripes in thread "unified storage setup on re-partitioned FP1" ("Steps for "fiixing" your upgrade").
i'm having Cherry 1.6, and two 7 GB partitions.
does anyone has a solution?

thanks, i've read it again and tried _keesj's solution again, unfortunately it didn't solve my situation.
i'm a layman in this area, so probably i shoudn't haved 'played' with partitions at all (but with the app it was easy).
my previous post wasn't quite complete... i have had an unified partition before...
because of an app that didn't work, i used the repartition app again to see if that could solve the problem.
it did, but later i wondered if a wrong install in the unified sistuation was the problem... so i thought 'let's try the unified partition again'...
i thought i could simply re-use the Fairphone Updater...
so maybe i'm now having a unified partition divided in 2?
and lost the ability to ever upgrade to newer versions of the Fairphone OS?
i hope someone can help me...

Make sure you allow it to reinstall the default recovery.

how do I allow it? i didn't get the question you've got ("ROM may flash stock recovery on boot. Fix?").
i downloaded Cherry 1.6 again and chose Install, gave it SU (forever) access, it automatically restarted to the Android with the text “Installing system update…” (no progress bar), and after a few minutes it restarted and nothing is changed. After starting the Fairphone Updater again, it immediately gave the Install option again. Same after selecting the Storage Upgrader.
I also tried restoring from the recovery (default, never replaced), from sd and adb (1.6 does install, 1.3 doesn't, and 1.6 partition upgrader doesn't either, gets aborted)…

Non unified images have a different signature. The moment you use the partition upgrader it will change the accepted signature and will no longer allow older images. If all is as I expected your running image is still the parition upgrader image and it contains the tools to perform the last step of the re-partitioning (e.g. calling the script and performing a recovery with format).
If you want to know what is going wrong with the zip install check the /cache/recovery direcotry. it will contain logs of the failing install.
As for a solutions I think you either need to run the script or flash your device using a 1.6 FUSE image.

I couldn't find any (log) files in /cache/recovery, but...
flashing the EBR1 from the FUSE binaries (FP1U) to my FP1 solved it! :victory:
thanks to _keesj, Rick (from Fairphone) and Christian (Fairphone forum)!
here is Rick's tutorial (with a few notes of my own):
You can only fix this by flashing your phone:
For GURU's only! (flashing with ADB). The alternative is to use the windows flasher tool.
1) Download the original image binaries from Fairphone's site (as a new user I, jjjanssen, can't post links yet).
(Download FP1U's zip: Fairphone_Cherry_1.6_FUSE_Image_2014-07-31.zip)
2) unzip the file
(I chose to unzip to location D:/FP1U.
after that i moved all content from the directory which contained EBR1, to D:/FP1U.)
3) enable usb debugging (on your phone: Settings, Developer options, turn USB debugging on)
4) push EBR1 on the phone: (Open (if you're using Windows) the Command Prompt)
adb push FP1U/EBR1 /mnt/sdcard/
(For instructions on how to use ADB search this site)
5) become root:
adb shell
(after that I also became super user (command su), but maybe that's not necessary; Rick didn't mention it. )
6) override the partition inforation:
dd if=/mnt/sdcard/EBR1 of=/dev/ebr1
7) reboot into recovery:
reboot recovery
8) choose to wipe data and cache
(after that, choose reboot)
