[HOWTO] get root back after ota update! - Nexus S Android Development

this is how i did it anyways. i had to flash the boot.img and update via stock recovery to get the ota to flash. but then no root!
so heres how i got it back:
download the superboot/paulobrien method (http://forum.xda-developers.com/showthread.php?t=882333).
boot phone to fastboot.
Code:
fastboot boot boot.superboot.img
let phone boot, open terminal, su, just to check.
reboot phone.
rooted and ota'd now!

I've got root back, but not by that method. I think it might be a mistake to flash that boot.img, as the 2.3.1 update patched boot.img... so replacing it with one from 2.3 might not be the best idea. But I guess no one really know what the changes might be.
I guess time will tell
The method I used was:
1. Boot into fastboot.
2.
Code:
fastboot flash recovery recovery-clockwork-3.0.0.0-crespo.img
3. Reboot from fastboot directly into recovery (not doing so will cause android to replace CWR).
4. Mount USB, copy su-2.3.6.1-ef-signed.zip to the /sdcard via windows/linux
5. Mount /system
6. Install update from zip (browse to were you put su-2.3.6.1-ef-signed.zip).
7. Install it, and reboot.
8. open root explorer, and rename /etc/install-recovery.sh to install-recovery.sh.old
9. open ROM Manager, reflash CWR.
now you are all done, rooted, w/ CWR

I reflashed CWM, then from CWM, remounted /system, then used adb to chmod 6775 su. That restored root pretty easily.
What Recovery image are you using? Are you able to get into it consistently? I can't from fastboot except for if I immediately hit it up after flashing CWM with fb, or from ROM Manager (flash from RM, then select reboot to recovery).

its not flashing it. read the command. its only booting to that image to install su. then reboot will bring you back to stock 2.3.1 boot.img.

im using stock recovery.

I'm rooted on 2.3.1 but I lose clockwork recovery when I reboot an gota reflash it using rom manager. Anyone having this problem

Sure it is. But on Android bootup, a script is running somewhere to replace it with stock recovery. They did this on Droid_1 after the first or second update (that's my only other android phone... so my android experience is limited).
edit: I just found the script. It's /etc/install-recovery.sh .... just renamed my to install-recovery.sh.old. gonna reflash CWR and test it now.
edit2: yep, works great now. CWR, and retained my 2.3.1 boot.img

So is this something that the devs of clockworkmod need to fix in order to not lose clockwork recovery when u reboot the phone

No, it's a safety mechanism so you can't lose recovery... It has nothing to do with clockworkmod. Someone can make a root script or app that disables it easily. Or people can just do it themselves manually.
edit: actually, all that needs to be done is add some code to the update script inside su-2.3.6.1-ef-signed.zip so when it installs the update, it renames install-recovery.sh

I want to attempt to restore my root by using your method. But I'm lost at the part when you use adb chomd 6775 su,
When I go into adb, do i just type chomd 6775 su? Do I have to download something else to use this? Please explain, thanks

If u dont mind can u please provide the instructions on how to do it manually. Id really appreciate it. Sorry im a noob lol

Where in root explorer do i need to rename

I'm trying not to be rude... but if you can post in this thread, you can read it to. Before you asked your question a couple different step by step posts outlined all you need to know.... and this thread is only 2 pages...

Is it just me or does adb remount no longer work?
If I use the old koush rootboot.img it works, but no wifi, if I use the stock boot.img, I get no wifi but am able to remount.

I can read an ive done all the steps u posted but my ? Is where in root explorer do i find /etc/install-recovery.sh so i can rename it? Im learning this as i go so excuse me if i sound stupid sometimes

do you have root explorer? if not, it's just a file explorer that has root access. by default when you open it you are at /
you need to scroll down to /etc
go in that folder and find the install-recovery.sh
look up top for the button to turn it from read-only to read-write, click it
go back to the file long press it, and then choose rename.

[TUTORIAL] Full Steps to Acheive Root + ClockwordMod Recovery with new KA6 2.2

I have put together some steps to take your fresh KA6 2.2 Official update and add Root and ClockworkMod Recovery. It may look hard, but should only take a couple minutes.
This is without ODIN or ROMS.
Steps:
0. Have yourself a T-Mobile Vibrant and PC Running Windows.
1. Use SuperOneClick (latest) to root phone. When you run the application, click the first button on the left and wait for the process to complete. Details will be scrolling in the middle window.(http://forum.xda-developers.com/showthread.php?t=803682)
2. Use a file manager (ROOT EXPLORER) or adb with root access to mount /system/ and remove bloatware (SLACKERRADIO and AMAZONMP3 and such) from /system/app/
2a. TOTAL NOOBS: Get SUPER MANAGER from the market (FREE). Then grant it root by going into SUPER MANAGER and selecting File Manager > [Menu BUTTON] > Setup > Enable ROOT function. Then go up levels, the top button on the file manager which will take you up a directory, until you get to / and scroll to the bottom and select [system]. Then select [app]. Then click [Menu BUTTON] > Switch System to R/W and press R/W. Scroll down and long press the slackerradio.apk to delete. You can do this too amazon market to delete and other useless apps.​
3. YOU NEED STEP 2 TO DO THIS STEP! Install Busybox from Market and run Busybox Installer to ensure its properly working and the latest is installed.
4. Run SuperOneClick again to place phone into shell root ADB (Second button from the left). Allow the process to run and then a pop up will say something about rebooting the phone. DO NOT DO THIS, continue on to the next step.
5. While in shell root from the previous step, run (3e) to (2e) modified recovery script. The instructions are simple. Download, unzip, and run the batch file found inside. This is ran from the COMPUTER NOT YOUR PHONE. Use the menu system to complete and then reboot as recommended. (http://forum.xda-developers.com/showthread.php?t=833423).
5a. NOT NOOBS: you can copy over the recovery yourself to /system/bin as mentioned by some commenters. If you do not know what this is, then ignore it.​
6. Remove any update.zip files from /sdcard/ and also remove any ClockworkMod directories using your favorite file manager or by mounting to a computer with a wire and activating the drive for My Computer. This is the internal one, not external.
7. Use ROM MANAGER from market to install ClockworkMod Recovery and reboot. This is free to download. When you launch, select the top item to install the recovery and then a menu will pop up to choose the phone you have. Happily select Vibrant. Once that's done, select reboot into recover right below that.
8. Re-install packages and it should reboot. You can navigate the menu using VOL UP AND DOWN and power to select.
9. Re-install packages again and it should boot into Clockwork Recovery. It should change form BLUE TO GREEN
ALL DONE.
That should do it for ya! Let me know if it worked out. Please follow all steps and don't cut corners.
Should you need to get back to ClockworkMod Recovery, you can use "adb reboot recovery" and re-install packages, or reboot into recovery with ROM MANAGER.
Edit Rev.a: added a step (6) Made the instructions more precise and added additional steps to clear up some confusion.(1-22-11)
Edit Rev.b: Added step 2a from request. root explorer is not free so use super, that works too. (1-24-11)
Edit Rev.c: Added more detail to the steps and added supplemental info for replacing the recovery with the modified one. (1-27-11)
Edit Rev.d: Super1Click has updated, so latest? works.
Side note: I do step 4 because from my experience, I had trouble getting the modified 3e script to get root. Figured might as well just give it root to begin with.
Side note: Yes I am aware that there are other methods and different ways. This was the noob way for me to convey it to the masses. I still do appreciate all feedback regardless of what it is. Thanks!

***For kicks you can do your 2.2 KA6 update the download Supercurio's KA6 voodoo kernel and ODIN it and have Root & CWM all in one shot.
***For kicks you can do your 2.2 KA6 update then download Supercurio's KA6 voodoo kernel and ODIN it and have Root & CWM all in one shot.
Not to hijack your thread...
Yea I know, but I wanted to find a way without ODIN.
added ur blurp
Reinstalling packages does not seem to work for me. Every time I click it and it reboots it keeps going into the samsung recovery menu... Help?
Does it give an error for signing or just looks like its working then reboots?
Looks like it works and then reboots
I didn't do this step though, would it affect anything?
2.Use a file manager or adb with root access to mount /system/ and remove bloatware (SLACKER and AMAZONMP3) from /system/app/
Double check if there is a update.zip and clockworkmod folder with a zip in it on your internal memory. I think the external card changed directories with the 2.2 update.
EDIT: infact, remove any update.zip and clockwork folder from the internal memory and run ROM MANAGER again and fresh download the clockwork 2.5.1.2. then check and confirm its on the internal. should be /sdcard/
once its confirmed there, then try again to reboot into recovery with rom manager

I would highly suggest doing that step. The system is full to begin with. Use Root Explorer and grant access, then mount system into r/w and remove the stupid stuff. You should do this to get Busybox on (AS IN BEFORE YOU INSTALL BUSYBOX)

Got it working man, thanks.
Awesome! Good to hear. This is my first tutorial and I'm stoked that its working well for others.
I've been an XDA visitor since my AT&T Titan WM6 days. I've done alot of flashing and modding since then and have always been able to find solutions without asking until now. This clockwork recovery issue is kicking my butt.
I am having trouble with steps 4 & 5.
what are the specific buttons to press on superoneclick in step 4?
How exactly do I use the file 3(e)_recovery_installer?
Thanks for any help.

4. Run SuperOneClick again to place phone into root shell ADB
For this step, run SuperOneClick from before, the same you used to root. The second button says "Shell Root". Click that Wait for it to say you have shell root until you reset.
5. Run (3e) to (2e) modified recovery script (http://forum.xda-developers.com/showthread.php?t=833423)
Just download the attachment in the first post and follow instructions. Its fairly simple process. Keep in mind, this may not work unless your phone is shell root from step 4
Thank you Nothingness. Cleared it right up. Worked perfectly.

[Q] Rom Manager on Nexus s claims device is not rooted

Hi
When I start the Rom Manager I get the message "You must root your phone for ROM Manager to function. Superuser was not found as "/system/bin/su" or/system/xbin/su".
I have followed the instructions here on how to root my Nexus s and I am able to enter recovery mode and am able to go into bootloader. I also see that is says "Unlock" there.
So the way I understand it, the phone is rooted. Unless I miss something here.
I also see the Superuser icon in my launcher.
What am I doing wrong?
Think this is the wrong area to ask but when you flashed the su file did you mount system in the mount and storage before flashing the su file?
I dont think it was mentioned in the guide.
how do I do that?
Can I reapply the su zip file again?

[Solved] Can't flash Clockwork Recovery.

I've read the guides, tried manual and the simple download from the Android Market. Here's what happens:
I've rooted my Thrill with SuperOneClick 2.1.1. It was a successful root from what I can tell, it added Superuser into my apps, and I was able to download Rom Manager from the Android Market.
If I try using Rom Manager and click "Flash ClockworkMod Recovery" It appears to install. But when I hit "Reboot into Recovery" it just reboots like normal.
If I try to manually get into recovery mode by holding volume down and the 3D button it just boots into the stock recovery mode.
When I try to manually install Clockwork and copy recovery.img to /data with cmd I get this:
failed to copy recovery.img permission denied

This is covered in the cwm thread in development section you need to use a file explorer that has root access and change permissions to the /data folder. You can use es file explorer, its free. Open it go into settings then browse as root... not really sure exact steps but they are in the came thread.
O my such a small step I missed! Thank you! Ill try this later today.
Permissions of /data are set to R/W but I still get the same error..
I'm starting to wonder if the cause of this is because I tried using Rom Manager to flash clockwork, THEN tried the adb method. Maybe it already being there is causing the permission denied?
edit: so it looks like it was as simple as me looking over the permissions and thinking I saw everything was checked, but really the two checks from the left under "other" were grayed out lol, checking those fixed it.

How to Install 4.2 images, keep root and all data

**Disclaimer** If you don't understand what follows, don't attempt this. I'm not responsible for you softbricking your device,
This is a quick guide for how to install the new android without losing anything. You'll need fastboot for this. Also, before doing this, be sure to download the supersu cwm update zip, and have it on your sdcard. Make sure you also already have a custom recovery installed (I did twrp, but i'm sure cwm will work just as well). I would also suggest having a backup done, through titanium backup and through recovery, just incase.
First, download the factory images for the n7 from google's website. Decompress them (if you're in windows, you'll need winrar or something similar.) After you decompress the archive, there'll be another one inside (image-nakasi-jop40c.zip), decompress this one as well. Under here, you'll see the .img files for all the partitions. For now, go up one directory. You'll also see here bootloader-grouper-4.13.img. Once you have all this, reboot into the bootloader.
Once you're in the bootloader, you can update the bootloader to the new version (this step isn't needed, but I did it anyways). Plug into your pc, and type fastboot devices. Make sure it's not blank. If it is, you have to update drivers. If you can see the device, open up a command prompt, and cd to the directory that has the bootloader-grouper file. Type the following:
fastboot flash bootloader-grouper-4.13.img
then, after it's done, type:
fastboot reboot-bootloader
Now, you'll be booted back into the bootloader, it'll say 4.13. On to the rom.
cd into the folder image-nakasi-jop40c (make sure you see the files system.img and boot.img before you continue. If you don't see them, the next steps will do nothing but erase your kernel and system parition.)
now, you see the image files. Type the following (still in the bootloader)
fastboot erase system
fastboot flash system system.img
wait until it completes, then type:
fastboot erase boot
fastboot flash boot boot.img
Once this is done, hit the volume up on the device until it shows recovery mode on the top. When it does, push the power key and you'll boot into your recovery (shouldn't be touched.) Inside here, flash the supersu cwm zip file, which'll flash the superuser binary, and supersu. Once this is done, do a factory reset (removing your data and cache.) Boot into the rom.
Once it's booted, you'll notice your internal sd card appears to be empty (mine did, I was worried at first.) For some odd reason, it moved the entire contents of my sdcard into a folder on it called 0. When you get back into android, simply move the folder all up one level so they're in the proper place. You now have the rom booted, rooted, with all your data. Now, you can do a titanium restore to get all your stuff back.
My first boot got stuck for some reason. if it happens to you, just hold the power button and hard reboot. (I did this on 2 devices, it only happened to one of them, so I figured I'd give you all warning.)

Thanks for this.
I flashed the 4.2 ota in the dev section and I lost root. Can I just flash the supersu binary in cwm to regain root?
Thanks for this.. Apparently you found out too a clean 4.2 isn't rootable via typical methods.
That SuperSU package did the trick. I have to remember to keep a SuperSU binary on hand for these kinds of situations that SuperUser fails..

Yes. If you do it though cwm, you're not using any exploits, you're just inserting the superuser binary and supersu.apk into the proper places on the rom. On any nexus device, any rom, this will root it.

Just got this working on a mac...
did not update bootloader(couldnt get it to)
other than that, same commands except all fastboots are ./fastboot on a mac
the only other trick is i needed the fastboot and abd files in the jop40c folder...seems to have worked like a charm....im deff on 4.2 with su installed... and it looks like my data is still there...once google is done restoring i'll know just how sucessfull it is, but so far, seems to work!!!

I did this all on linux, just kind of adapted the guide for windows. I figured all the linux users would understand how to do it on their own. Glad to know it's the same for mac as well.

Why so complicated?
I downloaded 4.2 from here:
http://android.clients.google.com/p...gned-nakasi-JOP40C-from-JZO54K.094f6629.zipia
I then just flashed it from recovery via CWM.
Done.
CWM asked me if I wanted to maintain root and of course I chose the correct answer on this, so now my N7 is running on a rooted 4.2.
Here is my method:
1. Download official 4.1.2 from http://forum.xda-developers.com/showthread.php?t=1929270 and 4.2 OTA image from http://forum.xda-developers.com/showthread.php?t=1989188
2. Boot into CWM (i have CWM touch installed)
3. Clear data and install 4.1.2, don't forget to turn on root in the installer
4. reboot check that root is fully working
5. reboot into recovery install 4.2
6. before reboot CWM will ask to disable recovery flash and protect root. Ansver yes to both questions
I'm confused, it says if you are already on a custom rom, just flash as usual.
What makes this different?
I was on stock ROM rooted with some system modifications, and this wwadd the only way I could get the update working...

So I'm at the step listed above. I have 4.2 on my device but I can't seem to find this "0" folder. I'm browsing the /sdcard folder via adb shell. Am I looking at the wrong place? Do I have have the incorrect permissions? Or might it not be there?
Thanks.
Ill have to wait until a rooted rom is created, I have no comp.

Not advisable to move this folder - if it got moved to a new location by the o/s then there's probably a good reason why - maybe like 4.2 introducing multiple users
Each user appears to get their own "home" directory created in /mnt/shell/emulated/
Default user dir is "0"
Second user dir is "10"
Each contain the standard dir's from 4.1 and earlier.

You had two extra characters at the end of your link, but I fixed it above and it's good to go for others in the future. Just flashed it in TWRP, it didn't ask if I wanted to maintain root, hit reboot when it was complete and lost root, so it doesn't work for everyone - good news is that all my data remained intact without having to resort to advanced restoring my data from a backup....
When I tried the SuperSU binary root flash trick, I finally got root back. But don't think it's as easy to get to recovery! I had to obtain the TWRP Recovery one more time since it wiped it and put in place a recovery that did absolutely nothing but reboot the device after a few minutes, so you'll have to
Code:
fastboot flash recovery openrecovery-twrp-2.3.1.1-grouper.img
to get TWRP back.... Hope that helped everyone!

[ROOT][CWM] Root Nexus 4 & Install Official ClockworkMod Recovery

I originally posted this method at AddictiveTips. The method I posted there is targeted at everyone including the absolute beginners and I have also included instructions there for setting up the required tools, and for reverting back to the original recovery and boot image in case anything goes wrong. All external credits should be given to that guide (it does link back to this thread). Here is the link: How To Root Nexus 4 and Install ClockworkMod Recovery on it.
To my knowledge, this is the first confirmed working rooting method for Nexus 4 posted here at XDA. Though my knowledge is limited, so please correct me if I am wrong.
UPDATE: There is an official ClockworkMod recovery for Nexus 4 now available directly by Koush, so this should all be easy as pie now and you can now safely install CWM too. I am updating the CWM method with the updated instructions.
This method requires an unlocked bootloader. You can find instructions for unlocking it at XDA, or at the AddictiveTips guide linked above (the link to the bootloader unlock guide is in the requirements section there).
UPDATE 2: If your device does NOT get wiped after unlocking the bootloader, fret not. While this isn't expected behavior, several users have experienced the same on the Nexus 4. This could be due to some error at Google's end, but unlocking still works perfectly fine.
That said, let's get on with rooting and flashing CWM.
ClockworkMod Recovery Method:
Download the latest official ClockworkMod recovery from CWM website and rename it to recovery.img
Enable Android Debugging from Settings > Developer Options. (If you can't find developer options, go to 'About' and tap 'Build number' seven times.)
Connect the device to your computer via USB, and install the required drivers.
Download the recovery flashable SuperSU package with Busybox and transfer it to your phone's internal SD card.
Reboot into fastboot/bootloader:
Code:
adb reboot bootloader
You can also power off the phone and then use power + volume-down key combination to get into bootloader.
Unlock the bootloader if you haven't done so already. WARNING: This command will wipe all data on your device.
Code:
fastboot oem unlock
Enter this command in a command prompt to flash the ClockworkMod recovery (making sure you are in the directory where you downloaded the recovery file):
Code:
fastboot flash recovery recovery.img
OR
If you simply want to root without flashing a custom recovery and want to stick to your stock recovery, simply boot this recovery once using this command:
Code:
fastboot boot recovery.img
If you flashed the recovery in the previous step, you can now boot into recovery by pressing volume-up or volume-down twice to select the recovery option, and then the power button to enter it. If you simply booted into the recovery file without flashing it in the previous step, you should already be in recovery now.
Once in recovery, take a backup to be on the safe side.
Flash the downloaded SuperSU and busybox package zip file from recovery.
Clear cache and dalvik cache just in case (not required but won't hurt).
Reboot the device.
ADB and Insecure Boot Image Method:
Grab the insecure boot image from this thread.
Also download these root files. This package includes the latest SuperSU 0.98, latest su binary that comes with it, and working busybox (not sure if latest).
Extract the contents of the downloaded zip file to your computer.
Enable Android Debugging from Settings > Developer Options. (If you can't find developer options, go to 'About' and tap 'Build number' seven times.)
Connect the device to your computer via USB, and install the required drivers.
Reboot into fastboot/bootloader:
Code:
adb reboot bootloader
You can also power off the phone and then use power + volume-down key combination to get into bootloader.
Unlock the bootloader if you haven't done so already. WARNING: This command will wipe all data on your device.
Code:
fastboot oem unlock
Get back into bootloader mode and boot into the downloaded insecure boot image:
Code:
fastboot boot boot.img
Don't worry, this will not replace your existing boot image and will only boot from the insecure one once.
If it does NOT work for you and you get stuck in a boot loop, simply reboot your phone into bootloader and use the above command again. Some users had issues with booting from it the first time, but a second attempt worked.
Once booted into Android successfully using the insecure boot image, simply enter these commands one by one in command prompt (making sure you are in the directory where you downloaded the files):
Code:
adb shell mount -o remount,rw /system
adb push su /system/bin/
adb push Superuser.apk /system/app/
adb push busybox /system/xbin/
adb shell
chmod 06755 /system/bin/su
chmod 0644 /system/app/Superuser.apk
chmod 04755 /system/xbin/busybox
cd /system/xbin
busybox --install /system/xbin/
exit
exit
Reboot your device.
You will now have root access. Tested and confirmed working by Stryder5 and many others.

You need to boot the unsecure boot.img first.
BTW can you confirm me the insecure boot.img you used? I just provided the link to the thread by Harry GT-S5830 but there were multiple ones posted in that thread, so I'm thinking of adding the direct link to the one confirmed working.

Glad to hear
Did you install the OTA before doing this? I gained root before installing the OTA.

No issues with installing the OTA after root?
Edit: Just noticed in your sig that you did not install the update.
I installed after ota

You mean you gained root after you installed the OTA?

I gained root, but haven't installed the OTA yet.
when I boot the boot.img. It rebooted and got stuck at the nexus boot animation for a long time. Does it suppose to do that?
Yes sorry gained root after OTA

Nope, it isn't. Try again...it's safe to try as many times as you want since we're not flashing the boot image; merely booting from it, which is temporary and doesn't last after reboot. Hope it works on the next try.
After step 8 we boot up the phone normally and then start running those adb commands? I'm assuming that's what you mean by "Once booted into Android successfully..." right? Sorry if it's an obvious question, just making sure!
quick question to ease my mind: if i needed to return this device for warranty purposes, how would i revert all of this back to stock? i know its something to do with the stock factory image, or am i wrong?

Step 8 itself will boot up the phone normally into Android, just using that insecure boot image instead of the stock one. And yes, you then just start entering those adb commands. =)

Best way would be to grab a stock factory image and flashing it. I recently wrote a post on the portal with the links: http://www.xda-developers.com/android/android-4-2-images-for-galaxy-nexus-nexus-7-4-and-10/
The method can be found at the factory images download page, and is as easy as extracting the image and running the included .bat file while your phone is connected to PC in fastboot mode.

so i extract the "occam-jop40c-factory-cd3dc140.tgz" file, then double-click the "flash-all.bat" file?
