New and Improved way to Unroot your device (much easier) [difficulty level 4]

So I am moving onto a new phone so I will not be supporting this thread anymore. Please help each other the best you can. Also if anyone wants to take over and support this thread feel free. Last but not least if anyone wants to use any of the items I put into this also feel free. Remember that android is made possible with contrbutions from viewers like you!
Check out my new guide its much easier and automated now!!
Sorry but I no longer have the files that were in the zip as my laptop that they were on no longer has a charger so I really don't have a way to pull them off until I come up with extra funds to buy a charger for that dinosaur!
I have updated the commands so everything will be working correctly.
Please note this a guide to unrooting your device and returning it to stock, if you have nothing stock and didn't back anything up i.e. modded rom, changed recovery, eng. bootloader.
If you didn't follow the ultimate guide then you will not need to follow steps 1-7. Just follow from 8 on.
Also keep in mind this was created assuming you followed the ultimate guide to permaroot turning radio s=off and changing cid thus unlocking phone.
I am not responsible for any damage to your phone blah blah blah.
Also if I am incorrect in any of these steps someone please let me know.
Also this is just a guide that I wrote using all the others. Please thank and donate to grankin01 for providing the original guide and also thank/donate to tiger013 for providing a stock nandroid. Also thank Football for providing new rom.
With that said here we go:
Download the PD15IMG file and rename it to PD15IMG.zip
1. Copy PD15IMG.zip and "part7backup-whatevernuberitscalled.bin" to the root of your sdcard
2. Connect your phone to your computer and navigate to your sdk folder then type adb push gfree /data/local
3. Open up terminal emulator or adb shell and type "su" press enter to get root privileges.
4. Type "cd /data/local" and hit enter
5. Type "chmod 777 gfree" and hit enter to make the program executable.
6. Now type "./gfree -f" press enter to run gfree again. It will disable wp on the emmc and remove the brq filter in the kernel. (as well as make another backup. delete this)
7. Now run the "dd if=/sdcard/part7backup-whatevernumberitscalled.bin of=/dev/block/mmcblk0p7" and it should show the output:
xxxx bytes in
xxxxbytes out
xxxxxxxxxx copied in xxxxxxxxxxx
8. Run "sync" and then reboot.
9. Let phone load then boot into bootloader again by holding volume down and pressing power
10. Let it load image and select yes to update.
11. Let it do its work it will reboot once this is normal.
And that should be it. Enjoy stock rom.

Great job! I un-rooted worked fine! Then I re-rooted worked fine also!

I assume this will not work if you have made a backup with clockwork? Also your instructions say apply nandroid backup, but there is no option in recovery for appy nandroid backup. There are options to update from update.zip and another one from a zip file. The folder inside you unroot package is not a zip file?

Well like I said this was done using no backups made.
Under clockworks recovery theres an option for backups and restore - this is the nandroid restore.

This is awesome! I'm getting a replacement mt4g in the mail soon, now I will be able to send my existing phone back 'unrooted'. Thank you!

Is this unroot like out of the box type deal. So that i can get future ota updates. I used ultimate guide to perm root. I am using stock rom. I am notsure if i should just do unroot.zip to unroot for future ota updates.

I put the nandroid file on my sdcard, but in recovery when i go to restore there it says no files. What do I need to do to get this to work. I have a replacement coming to me so I need to figure this out.
Edit: Sorry I'm an idiot. I got it know. Thank you so much for posting this.
Edit2: Crap! Ok I have s=on now but i still have hboot 0.86.0000 Shouldn't I have the old one now?

Where is the "part7backup" located? Also, what is it?

this sucks... i followed everything perfectly but now my recovery is screwed up ugh this is so frustrating i have that stupid phone with a red triangle thing when i try to boot into recovery (yes im aware its supposed to be stock recovery not clockwork)

[Q] Problem with adb remount

OK I know this problem has been posted hundreds times before but i've read several of them but still can't find out what i did wrong. SO: I got my G2 rooted with S-OFF as i looked in the bootloader. I rooted the phone using rage method. So if i have my S-OFF that's obviously that i am rooted right?
And I definitely have my adb set up right cuz i could not root my phone if i didn't have adb set up. The question is Why every time I try to do adb remount, it will keep saying remount failed operation not permitted.
Even when I try doing adb shell and su it would say access denied too.
Just a little frustrating, What can i do to fix this?

I am not %100 if this is your problem but i think you need ENGINEERING HBOOT
to run adb commands ,you can do it by reading the wiki http://forum.xda-developers.com/wik...Z.2FG2.2FDHD.29_-_OPTIONAL_and_UNNECESSARY.21
But if you want to do it be very very carefull becasue if you do it wrong you will brick your phone and there is no way back

S-OFF is different from having your phone rooted, so it sounds like your rooting hasn't worked. If you have S-OFF and the eng hboot, you could use fastboot to flash Clockwork recovery and then install a custom pre-rooted ROM.
Or you will need to go through the rooting procedure again to see what has gone wrong.

If that's the case that my phone hasn't been rooted. My rom manager worked. I flashed clock work successfully and I did checked that I had it by rebooting into recovery. I even used n1 torch high brightness to make sure I was rooted. Then extra step was asking su in my terminal emulator too. But I still had hboot.img tho. Should I do an engineering hboot ?

The ADB remount command requires the ro.secure property to be set to 0 (even if you are rooted). If you want to remain on the stock ROM, flashing the linked ROM will do it for you (and is way easier than doing it yourself manually). Most (if not all) of the custom ROMs will set this property for you if you wanted to try others as well.

Thank you guys very much. I never faced this problem before since my n1 was rooted and flashed rom using the phone not adb our anything related to computer.so thanks guys. Case closed. Happy me lol

Need Help Testing for Temp Root in DL17

Folks,
I need someone on DL17 to test for root access. Due to the small community, I haven't heard if anyone is rooted on DL17.
While I can build kernels and get clockwork working for DJ20, for DL17, I need the stock kernel dumped, and for that I need root.
Steps:
1. Go to Index of /files and download rage.bin. (right click, save as)
2. Copy or adb push rage.bin to /data/local/tmp on your phone.
3. In adb shell:
Code:
chmod 755 /data/local/tmp/rage.bin
Then
Code:
/data/local/rage.bin
It will give you a wall of text. Wait a few minutes, hit ctrl-c to close adb shell, then type
Code:
adb kill-server
Then do adb shell again. It should (hopefully) take you to a # prompt. Please report back.
Thanks.

[Q] Alternate method of flashing CWM3

Is there a method of flashing CWM3 via update.zip in samsung recovery? I don't have a functional USB cable to use with the One Click method :/. Sorry if this has already been answered, I couldn't find an answer through searching. Thanks in advance!

No, but luckily USB cables are dirt cheap these days, I'm sure you can find one for < $5, or if worst comes to worst go to Sprint and beg a rep to replace your cable.

Lost the one that came with the phone, only have one which I stole from another charger and the device isn't recognized at all (tried it on multiple pcs). I really don't want to buy one as I never use it except for the CWM flash. I have a SD card reader to eliminate the need for cables.

Well, you need one if you're going to flash CWM, if anything just think of it as making your life easier in the long run, no more taking the SD card out just to put files on it.

Frankly I wouldn't mind if there were a way to do it manually in terminal.

*bump* Anyone have any ideas for a method of using terminal to do this?

it can be done in terminal, just open the batch file and read what it does via adb and do that in terminal

I started to do that but cant get past the exploit (rageagainstthecage). I get permission errors and can't even copy the file to /data/local/tmp. Any ideas?
EDIT: It's because the data partition cannot be modified without root access. Somehow adb bypasses this.

Adb runs with root access i suppose... let me look at something..

I basically need a method of obtaining temporary root on the device without using a computer. If i can do that, I can flash cwm using redbend_ua and then flash a rom/kernel for perm root. If it helps, i'm on OTA EC05
EDIT: Does redbend_ua require root access?
EDIT2: Nevermind. I tried running redbend_ua to flash the recovery image and got an error about /data/local/fota missing.

does z4root work on froyo?
http://forum.xda-developers.com/showthread.php?t=833953
if it does.. then

Is there another method of rooting I can do manually? That's the real problem here. I need root to run redbend_ua and from there i can do everything using clockwork. OR some other way to flash clockwork that doesnt require root but it seems that doesn't exist.

Well previously koush had an update.zip that would run in stock recovry and install cwm.. but it stopped working as of froyo, I'm assuming the recovery signature changed. Maybe contact him via twitter or something and see if he ever made a new one..

[HOWTO]Recover From a Bad Flash - Now automated

Ok so you accidentally tried to Odin or CWM the wrong file to your phone. Well the good news is that if you can get into CWM with access to the sdcard(s) or access ADB we can fix it. If the phone won't power on at all, you can't access cwm with sdcard(s), ADB or Odin you are unfortunately out of luck. You will need to get it repaired by Sprint or send it off for a jtag repair.
Disclaimer: I am not responsible for anything that happens to your phone. You do this at your own risk.
If you don't own the E4GT do not use this guide because if your partitions are not the same as ours you will brick your phone.
If by chance you can get into Odin mode and your computer can see the phone go buy a lottery ticket J/K. All you have to do is download a full tar and Odin it back on. I won't go into details for that as it is well documented. Or you can still use this zip if you prefer.
I have automated the process of the restore. What this zip will do is flash the Agat 0.5.4 source kernel so you have cwm. It will flash the FH13 boot.bin, hidden.img, param.lfs and Sbl.bin. It will wipe Cache and Dalvik also.
This will not flash the modem, wipe data or replace system. So after you use this zip if your modem is also hosed flash a modem zip from CWM. Once you have recovered the phone you can flash whatever you want back on the phone.
Download CWM Odin Restore To FH13: http://d-h.st/3yZ
Copy the zip file to your phone and flash in custom recovery.
If you don't have access to the sdcard(s) but do have access to ADB proceed to the second post.
If you need some direct assistance you can PM me and I will work with you when possible.

You only have ADB access
For this method you will need CWM, ADB, Root and the image files to restore.
If you don't have ADB installed I have attached it to this post. I have also provided a link to the FH13 image files.
If you don't have ADB, extract the ADB directory to the root of C:. So you should see C:\ADB
You need to know where your ADB directory is located. If you used step 1 ADB it is C:\ADB. If you installed it on your own you should know where to find it.
Extract the images.zip into the ADB directory. You should now have the Images folder in the ADB folder.
Boot into CWM and attach your phone to the computer.
Open a command prompt and change directory to the ADB directory cd C:\ADB (or wherever your directory is).
Type adb push Images /tmp and hit enter.
You should see something like 6 files pushed. 0 files skipped.8465 KB/s (19271020 bytes in 2.223s).
Type adb shell and hit enter.
This part is critical. Make sure it is typed exactly or you can/will destroy your phone.
Copy and paste or type the following commands. If you copy and paste make sure you don't copy any leading or trailing spaces. Hit enter after each command.
You can skip any of the following commands if you know you don't need them. For example, if you know you only installed the Sbl.bin then you only need to enter that command. I have provided them all to cover all of the needs. If you are not sure just do them all.
dd if=/tmp/boot.bin of=/dev/block/mmcblk0p0
dd if=/tmp/hidden.img of=/dev/block/mmcblk0p12
dd if=/tmp/param.lfs of=/dev/block/mmcblk0p4
dd if=/tmp/Sbl.bin of=/dev/block/mmcblk0p2
dd if=/tmp/zImage of=/dev/block/mmcblk0p5
dd if=/tmp/zImage of=/dev/block/mmcblk0p6
You should see something like 2560+0 records in, 2560+0 records out, 1310720 bytes (1.3MB) copied, 0.265521 seconds, 4.7MB/s after each command.
Reboot your phone and it should boot up.
If it still doesn't boot something didn't take and we will need to work one on one.
Download the Images.zip: http://d-h.st/8gY

The bootloader restore has been proven to work on one phone so far. Thanks to pjkingphd for testing and confirming that it works.

I have now automated the restore process in a zip file. You must be able to copy the zip file to the phone for it to work. I have flashed it about a dozen times but I would like to get a few brave testers to try it on your phone for me. Make sure you do a backup first! I have moved the manual commands to post two and revamped the instructions.

Yeah this will fix you up. Once you get recovered you can flash whatever you want back on. Since you are an advanced user if you have a particular setup that you want to restore, just pull those files from the tar and place them in the Images folder of the zip.

You never can be too sure.. Lol I just always expect the one time I make an assumption will be regretted.
Good idea btw... And thanks.
And Ive actually been meaning to flash a param.lfs..... I have like 4 OCs it just they are all the way on my backup backup card ...(see my level of sloth ?!?!?!)
