[Q] Questions about a complete wipe - Samsung Galaxy Nexus

Hey guys,
I have a Gnex with android 4.2 stock bigxie. Yesterday I installed Purity 1.1 and find out that my storage had now the 0/ problem. So installed the latest cwm and tried everything again. Still had the 0/ problem. I also got messages like the phone's storage is full. And restoring NOVA launcher and TB backups was a pain in the a$$. So now I'm considering al complete wipe. Yes complete. I found this on a android forum. Is this the correct way or will this be harmful for my precious Nexus? I simply can't stand how my storage looks right now haha.
-> Instructions for a bad day: Completely wipe SD, reboot recovery, factory reset, format system, reboot system.
Is this correct or do I need something else? I'm not looking for the bootloader re-unlock way. That's too dangerous for my precious.
Thanks in advance!

Format /data too. So make a backup first

So I can do this without any problems? I can go on flashing new roms and kernels?

If everything goes well yes, then your device will be completely blank, you will need to flash a ROM via fastboot

When I completely wiped everything, should I do this?
"ROM Flashing
Obtain a ROM of your choice, and note the location on your computer.
reboot your device into fastboot mode via one of the following options.
adb reboot bootloader (requires USB debugging to be turned on).
power off the device then back on with 'vol up' + power button.
Wipe your device.
fastboot -w
Update your ROM.
fastboot update </path/to/your/RomFile.zip>
Your phone will update and automatically reboot into the new ROM."

Can't decrypt Galaxy Nexus after OTA

Just applied the 4.0.2 OTA update to my GSM Galaxy Nexus and after the reboot, even though i type in the correct password, my phone wont decrypt.
I read on android forums people with the 4.0.3 OTA having the same problems.
How can i reset my phone? How does Odin work? Somehow i am stuck at the screen with the android and his open chest
ok i got odin workin, needed to install the android sdk, wiping my phone now
Please note: YOU WILL LOSE ALL DATA
everything seems ok, i got into odin mode like this:
-connect your GN with usb to your computer
-start with power + volume down
-use volume up / down to select recovery mode
-confirm by pressing power
-you will see an android with a triangle
-press power and volume
-select factory reset
-confirm with power
-reboot
this worked for me only after i installed the android sdk, before that somehow i was stuck at the android with his chest open and couldnt select anything because somehow my device wasnt recognized
hope this helps
This also caught me out. Not happy.
Method I used (posted on OTA thread) worked without installing SDK:
Power off
Hold Volume + , volume - and power
You should get a green android image with the body opened with "Start" on the screen
Press Down till you get to recovery mode
Press power
Phone will reboot
You will then get same image of android (smaller) with red warning triangle
Wait a minute or two and then press volume + and power (not sure exactly what I did for this maybe it's just waiting)
Use volume down to select wipe data/factory reset and hit power
Select Yes - delete all user data and hit power
Once done select reboot system now and hit power
You are now back to zero and can start again.
Hi I have roote, and installed cwm, I the applied the encryption proces, now I want to flash a ROM (revert to stock) thru cwm, it says can't mount SD card. I try do a factory reset through cwm but also says can't mount....
Any tips on how to remove the encryption?

The only way to decrypt an encrypted phone is using fastboot. Fastboot is a developer tool that runs on your computer. You need to download the full Google factory image or a full rom, and flash all of the files to your phone using fastboot.
CWM and other recovery software will not be able to factory reset the device.

This is not entirely true. You should be able to use TWRP 2.2.0. As well, have a look through this thread.

[Q] [VERY STRANGE] Wipe data doesn't work anymore!

Hi everybody,
I'm getting into the new AOKP Milestone 4 from the Codename 1.5.0 - so I downloaded the files and get recovery (clockwork 5.5.0.2) to make the wipes and flash the new rom and gapps... the usual routine.
Wipe data - Wipe Cache - Wipe Dalvik - Flash AOKP - FLASH GAPPS - REBOOT
1st strange thing after that: the Old Franco Kernel bootlogo. And in stuck, obv.
Why the Franco bootlogo? Bah, re-wipe everything and go on...
Nothing, stuck on Franco. So I decided to re.wipe everything again and re install the Codename android, 1.5.0 - the same wich i was coming from - to get the phone work for tomorrow. And here we go for the biggest surprise.
EVERYTHING IS HOW I LEFT BEFORE THE WIPES WHEN I WAS ON CODENAME!!!!!
Same routine, flashed Codename and reboot. Franco logo and then no configuration wizard, no backups.. everything was EXACTLY like how i left before the first attempt!!! My apps, my homescreen, even my login account, like i have never attempt any wipe or flash!!!!
IT DOESN'T WIPE ANYTHING, ANYMORE!
I'm getting mad.. tried this ten times. It's like nothing is getting wiped!
P.s: clockwork is correctly installed.. i've tried TONS of roms on my gnexus, everything has ALWAYS worked fine. No errors during wiping, usuals script "wiping /data .... wiping /cache etc.." until "DONE". No error flashing the AOKP.
Help please..

Hey there,
mike, the dev from Android Revolution HD, has a super wipe script in his thread, on the first page, might want to try that one.
It works like flashing a ROM

You are not wiping correctly. You are having problems because the system and boot partitions were not wiped at all....

Already tried. Same results, it ends successfully the superwipe string.. and then no wipe at all!
adb reboot bootloader
fastboot -w (might wipe SD card)
or
fastboot erase system
fastboot erase userdata
fastboot erase cache
fastboot update update.zip (for installing the rom)
Ok new infos.
From the log file the /data wipe seems to be undone due to the "filesystem is read only".
Any ideas?
Stupid question... but maybe check if the device is still rooted and unlocked correctly?
Maybe something messed up there...
these are signs that the internal hdd is getting screwed up... like the partition values... its a known issue for all samsung devices. the i9000 had it, the nexus s had it. they even have a lot of threads out there reporting issues abt it but no fix till now. i even had it with my nexus s (which is now a paperweight)
some fixed it with a simple wipe using oem lock n unlock, others fastboot wipe....
the most common symptom is that you can see a lot of files on your phone, but can neither delete them nor add anyting to the sdcard.
As anton2009 said, you should try wiping all the partitions, then reflash CWM, then flash your ROM/kernel.
Reboot into fastboot and type the following:
fastboot erase boot
fastboot erase system
fastboot erase recovery
fastboot erase userdata Note this will wipe/sdcard
fastboot erase cache
Then flash CWM and then ROM/kernel.

I am also having the same issue. However I just reflashed a bunch of roms and even though all my data is still there everything seems to be working fine.

Guys, all of your data is stored on the userdata partition. Most ROMs I don't think flash that partition, so all the data still remains. As well, I don't think every ROM includes a kernel, so the boot partition is not erase either. Wiping in CWM does not wipe /sdcard (which is actually located on the userdata partition as /data/media).
Use what I had posted 2 posts up and it will certainly wipe.

I also think your solution will work well.
My only question is about new rom flashing: erasing ALL datas even in the /sdcard how will I be able to flash new roms if there will be nothing more on the phone? Where will i get'em?
Will I need to flash again even the CWM?
Sorry for the stupid question..

You can still wipe userdata, boot into Android (obviously you can't do this if you wipe system), and download a rom from there. Otherwise you can download a rom onto your computer and then:
adb push /where/your/file/is/rom.zip /data/media/download
This will put the file from your computer to your download folder in your SD card. I'd recommend pulling any necessary files before you wipe userdata (such as music, pictures, etc) or you can pull the whole SD card (adb pull /data/media) and then cherry pick what you want to add back later.
SOLVED.
Wiped all with fastboot, pushed new rom with adb push and flash it.
Just to feel relaxed installed a couple of apps, gone back in recovery and tried to wipe data/cache/dalvick then re-flashed AOKP, everything is now working fine, the wipe erase all app and userdata now.
Hope this won't happen anymore.. thank you all..

I feel sooooo newbie, but.. how can I do that?
Backing up and restoring /sdcard is very time-consuming and usually unnecessary in these situations. It only takes a minute to fix the filesystem errors on /data and then you can wipe data as normal (in CWM, no need to use fastboot which also erases /sdcard). Just boot into CWM and in an adb shell:
Code:
e2fsck /dev/block/mmcblk0p12
Answer 'y' to everything if prompted. Done.

[Q] Uh-Oh, TWRP not allowing me to mount via USB

$10 paypal to who can help me solve this
Here's the deal people,
My GNex was slowing down and acting all funny with stock 4.3 after about 6 months
I finally decided to try out a 4.4.2 ROM
I had TWRP on the phone so I said I'd just copy the Zip to the root folder along with the Gapps
Long story short, I accidentally wiped the storage.
Then I said no biggie, and figured that I'd just mount the USB to my laptop and transfer the Zip file of the ROM I wanted over to the storage.
BUT when ever I tap on mount USB nothing shows up in the devices.
Now I have nothing to transfer the files to.
I have windows 8 on the computer I'm currently using if that matters.
Forgive me people. I am not an avid flasher like I was when windows phone 6 was still around. So spare the insults . Just need my phone running so I can contact my loved ones
Galaxy Nexus uses MTP instead of Mass Storage mode, so you can't mount it as usual.
However, there's an "ADB sideload" option that lets you sideload a ROM from your PC using the ADB command (if you have the drivers installed, in the command prompt window, just type "adb sideload *THE-PATH-TO-YOUR-ROM-FILE*").
Find out more with Google

agh I have read that the drivers don't work on windows 8 PC's . But I'll try
I flash my phone usually 2 or 3x per 12 months. so please pardon me if I forget some things...
In addition, the phone has nothing on it but TWRP
so no OS is on it at the moment. and no USB mounting.
I think USB mount is used for mounting USB flash drives attached through USB OTG.
The essentials. Contains ADB, fastboot and USB drivers from the Android SDK (should work on 8 and 8.1).
ADB_usb-driver.zip (8.79 MB)
To transfer files within TWRP, you need to use adb. Start by installing the driver. To verify for successful driver installation, type in:
Code:
adb devices
It should show you a "List of devices attached" and there's at least 1 item in the list.
Then copy the zip you want to flash into the same folder as adb. Let's say the file is named rom.zip. To "push" it to the phone, use the following command:
Code:
adb push rom.zip /sdcard/rom.zip
After it has finished "pushing" the file, just tap "Install" in TWRP and the zip file should be there!
You can now proceed flashing the ROM of your choice.
If you have wiped the storage without subsequently booting into a working ROM, the internal storage partition will be unformatted and you may have trouble writing to it.
If this is the case and you don't have a bootable ROM, you will need to flash a stock ROM via fastboot first and boot once, then try the whole thing again (don't wipe userdata this time!).

THis is my issue now. I was able to get the GNex wugfresh toolkit
I was able to push the original 4.4.2 ROM that I wanted over to the device. But It keeps saying failed at the install point.
Good thing I came back to read this post. Thanks. Ill try to flash by fastboot
EDIT Now im trying to do it via fastboot and its saying AdbWinApi.dllis missing.
I keep hitting these damn road blocks. Im sure I have many people calling and texting me.
Can you temporarily put the SIM in another operable phone to get your calls and texts?
Not sure about the fastboot error. You'd need to download a Google stock ROM image directly from them, and fastboot flash the system and boot partitions. This should be enough for a reboot to regenerate the user data partition. You cannot flash the custom ROM in fastboot unless a version has been made available in that format.

Yes, why would I say it if it were not my experience that it is so?
On Nexus devices, a userdata wipe from the bootloader often leaves it in a state where custom recovery cannot write to data. Booting once into a bootable ROM typically fixes this.

I mean, is it true that after wiping all partitions (data, cache, dalvik, system, internal storage) in recovery, you cannot sideload a ROM as usual? What error does the phone give? And why does wiping breaks partition table, when all it does is *independently* formatting all partitions?

I don't have all the answers to that. Wiping data in custom recovery should not be an issue because TWRP & CWM are both designed to keep /sdcard intact and erase the rest, which means it's just deleting files not formatting the whole partition. What I'm saying has to do with when you're in *fastboot* and you either factory reset, reflash userdata.img or wipe userdata.img, or unlock the bootloader.
On my GNex in this situation, circa 1.5 years ago, TWRP gave an error in which it thought the data partition was encrypted. CWM did not give an error but any files I attempted to write did not actually stick. One boot into a working ROM fixed it.
I have also observed that after a fastboot wipe, it starts booting into the ROM, possibly displays the Android "unpacking" screen, and then resets to the Google splash screen one more time, and then the second boot is the successful one. I have no idea if it has to do with permissions, formatting, or whatever else, I just know that it happens.

Your 4.4.2 ROM install most likely failed due to outdated TWRP. You must install twrp 2.6.3.2 via fastboot first, then you should be able to install and get going.
Let me know if you need links to anything

Also, next time don't "wipe/format data" in twrp. Do factory reset. (Unless they changed the damn name again on us lol)

[Q] How to pull data when in Clockworkmod Recovery Mode?

Hi guys
I am running Cyanogenmod 10.2.1 on a Galaxy Nexus GSM. I installed that last year with the easy to use installer.
2 days ago I clicked update on that M3 Snapshot. Since then, the phone is not booting anymore and hanging on the blue loading screen with the cyanogenmod face and the circle around it.
I can boot to Odin and Clockworkmod Recovery.
I installed the Android SDK and the USB adb drivers and it shows the device under "devices" without trouble but not as a storage device so i cant pull data via the windows explorer. I am on Windows 7 Ultimate.
When in CWM Recovery and trying adb pull it says device not authorized. Unfortunetly i switched off usb debugging right before i installed that update.
My question>
I have to save the photos from the internal sd card before i can just wipe everything and reset it to factory setting. How can i do that?
Any chance to get around the "device unauthorized" msg ? Via adb devices i can see the device in the list.
I searched around a lot and kind of out of options now :/
if it is any help. i was just able to flash the clockworkmod to 6.0.4.7 via heimdall in odin mode but i still cannot read data from the phone..
if its possible to write on the phone it should be possible to read from it?

ok if anyone cares for the solution:
i got all mad. i booted into cwm recovery and did the wipe all/factory reset. after that i clicked system reboot. the old cm booted smooth and quick. and all data on the internal sd card is still there. just the apps and their data is gone. pictures saved.

Nexus stuck in boot loop - unrooted - Backing up photos from bootloader or recovery

Hi.
Apologies if this is a very naive question, I am not particularly familiar with mods, roms and so forth.
I have rooted another phone in the past, but that is all.
The situation:
- Samsung Galaxy Nexus
- Not rooted/unlocked. Stock android automatically updated to the latest Android version supported
- Android developer option NOT set in settings
- Stuck in a boot loop: boots to android and then after a few seconds reboots, so no time to do anything
- Not sure how it happened, I had it for years, it was in my pocket and suddenly started doing that.
- Android fastboot and recovery loads up no problem
- I have tried anything I could find online to fix it: deleted cache, rebooted in safe mode, removed battery for 10 hours
- Nothing seems to fix it, it keeps rebooting
- I want to try a factory reset, but my family photos are in the phone
- Google synch seems to have stopped functioning for this device a year ago, all my 2016-17 photos and videos are locked in the phone.
Admitting there is nothing to do about the loop problem:
Is there any way I can copy photos and videos via usb while in recovery mode?
After I will reset the phone via recovery menu, hoping it will fix it. IF that does not fix it, I will flash another rom in. But I really do not want to wipe my data before backing them up.
I am assuming the answer is no, you cannot access the internal memory in fastboot/recovery unless your phone is rooted.
But I would like an expert opinion before I resolve to wipe one year of photos and videos which I will regret losing.
@mcaldo DON'T DO FACTORY RESET, EVERYTHING WILL BE LOST
which recovery are you using..?
if it's TWRP, then it's easy..
- boot into TWRP recovery
- go to "Mount" tab
- find "enable/disable MTP" button at lower options.. (enable it )
then connect your phone to that PC, where you always connected in past, ( to eliminate driver installation stage, all drivers will be preinstalled )
Regards

Thanks for your reply!
By recovery, I meant 'android system recovery'
It gives me the following options:
reboot system now
apply update from ADB
apply update from USB drive
wipe data/factory reset
wipe cache partition
Is any of the above useful?
Unfortunately, I do not have any alternative recovery software available
Edit: Googling I found this: "Apply update from ADB: The Android Debug Bridge allows you to plug your device into your PC and issue commands from there. "
If I can issue commands through ADB, perhaps there is a command to copy data from my phone to my computer?

wipe cache partition
Is any of the above useful?
Unfortunately, I do not have any alternative recovery software available
Edit: Googling I found this: "Apply update from ADB: The Android Debug Bridge allows you to plug your device into your PC and issue commands from there. "
If I can issue commands through ADB, perhaps there is a command to copy data from my phone to my computer?

Yes, you can copy through adb commands..
Get and extract Minimal ADB and Fastboot from here: https://forum.xda-developers.com/showthread.php?t=2317790
From PC, run CMD to extracted folder directory.
Connect phone to PC, go to update from ADB(in recovery),
Type "adb device" , it will show serial number and connected..
Then "adb pull /sdcard " (if you know particular directory of data then write it like /sdcard/photos,, otherwise writing /sdcard will copy all folders from your phone. )
it will start copying to same adb folder ..

Thanks for the advice.
I followed the instructions closely, and nearly got there.
adb devices returns
#serialnumber sideload
so all good
but adb pull /sdcard returns
adb: error connect failed: closed
I tried several other commands with no success
kill-server and start-server work fine but do not solve the problem
adb usb returns
error closed
So, I am starting thinking that the problem is in the bootloader being locked.
However, if I unlock it, it will be wipe all my data, I understand?
Googling about it, I found this:
The behavior is status-by-design. Your stock recovery is not designed to grant shell access. Your only choice here is to somehow manage to flash a custom recovery. – Firelord Dec 30 '15 at 14:19

To achieve something similar to what @FireLord suggested: TWRP can be booted on many devices without being installed. For that, find a matching image, then boot to the bootloader and run fastboot boot twrp.img. Btw: you can check with fastboot devices resp. adb devices whether a device is visible to the corresponding tool. – Izzy♦ Jul 8 '16 at 19:40
So I understand one could boot TWRP without installing it, but I am not sure if that means I could do that with the bootloader locked?
I found WugFresh nexus root toolkit which seems to do that, among many other things, but again it warns that the phone must be unlocked (using the android build "Android *.* Any", I did not know what else to choose, not sure if that makes any difference as for locked/unlocked requirements)
EDIT: my fastboot screen reads "FASTBOOT STATUS - Failbootloader locked" as the last line, when trying to run TWRP without installing.
Yes, unlocking bootloader will wipe everything..
What actually you did ? Why it went into bootloop ???
I have also read that about boot into TWRP without installing.. and it worked for many one without unlocking bootloader... Don't know why not on GNex.

A very good question, to which I have no answer, unfortunately.
The phone was used by my wife for 2 years and then by me for other 2. I recently changed the battery.
Never rooted or unlocked. No unusual apps installed. I am a very basic user, as you might have guessed, and being my only phone at the moment, I really would not risk experimenting with it.
It went very slow over the last 4 months, so I was planning to reset it.
I put in my coat pocket for a few hours, when I took it out it had a train ticked stuck to the screen and was quite warm and on the lock screen. It froze, so I took the battery out and restarted it. From then on it is stuck in a loop, not sure why really.

That's good to know. I'll research more than.
It seems there might be a problem with the fastboot drivers on my computer, even selecting them from device manager did not work. Win7 refuses to install. The ADB drivers in theory work fine though.
If you have done nothing modification to system, then wiping data should work, but i have doubt if it also wipes personal data too, on TWRP it wipes data excepting /data/media/ which contains all personal data.. but don't know about wiping on stock recovery...
I hope you will find solution as soon as possible..
Regards.
PS. I can install stock recovery and try wiping /data.. and check what things get wiped.. but i need little time for that experiment...

Thanks so much.
Looking at google's documentation on the nexus:
You can remove data from your Pixel phone or Nexus device by resetting it to factory settings. Resetting to factory settings is also known as formatting the device or doing a "hard reset".
If you're factory resetting your device to fix an issue, make sure that you've tried all other troubleshooting options first. Find out how to troubleshoot your issue.
Important: Performing a factory reset will erase all data from the device.

It would seem that indeed all data will be removed.
This point, I will research a bit more into drivers, in case that is what it's preventing adb pull from working.
I really need a working phone, so if that fails I will hard reset, then unlock, root, flash in an alternative bootloader and perhaps a rom, and put ubuntu touch in dual boot. That will hopefully prevent me from loosing data in the future.
Sorry, this is out of topic to my question, but, , could you suggest any stable, solid rom for the nexus?
I read good things of CM12, and I ran into one which seemed to do to quite well with split windows, but I do not remember the name right now.
EDIT: I remember the name of the rom now, it's https://omnirom.org/about/
A last question if you can..
I tried to solve my boot loop problem by sideloading an update from google (maguro yakju yakju-jwr66y-factory-4cadea65.zip)
It loaded it fine but then failed because the installation it says it is not signed.
Basically, being a stock bootloader recovery from Samsung, it will only sideload OTAs from samsung, not the stock ones from google..
I cannot find the samsung ones anywhere, not for the nexus anyway, just the newer devices..
By any chance do you know where I could download proper Samsung OTA zip updates for the nexus?
Well, I talked with an android developer who confirmed that, unless you have a friend working in criminal forensic technology or similar, there is no way to get around a lock on this phone to pull data out.
So, sadly, I have wiped my phone by unlocking it, flashed TWRP and then omnirom with gapps.
My photos are gone, including a bunch of stuff my kid had made and asked me to photograph for safeeping. Very safe indeed
He kept asking me why they make the lock like that, instead of allowing some kind of password, perhaps he has a point.
So, it is quite unlikely that somebody who knows as little as I did will ever read this *before* finding themselves in the same situation.
But if you do, back up your data, unlock and flash TWRP, clockworks or some alternative, and thank yourself if and when disaster strikes..
@mcaldo wiping data/factory reset in STOCK RECOvERY will wipe everything... There is very few chances to get backup...
And yeah i found something interesting..
You can flash system.img.. only system files will be corrected not anything else..
Get appropriate zip from here : https://developers.google.com/android/images
Now take system.img to ADB/Fastboot folder ( i assume you know how it works )
Just go "Fastboot flash system system.img"
It will rewrite system partition..
Another one:
See downloads on this thread..
One says NON-WIPE, if you want me to try that zip, i will again require time for that. See here : https://forum.xda-developers.com/galaxy-nexus/general/guide-restore-to-stock-unbrick-galaxy-t2065470
