Wait, let me get this straight. You're saying right now there's no way for many of us to get a root access to our devices if the abovementioned method is not working, right?
For those with 'partial' root after JB update - regain root!

As far as I know, unless someone is keeping a HUGE secret.
I should mention the unlocker from ASUS but i don't know if anyone has tried it on JellyBean

jamesh1979 confirmed his success with the unlocker on JB. http://xdaforums.com/showpost.php?p=32189475&postcount=19
BTW is it possible to root with the unlock tool? If so how?
It is more insidious than a straight unlock. You have to be unlocked to actually flash back to 4.0.3 stock asus firmware, then root. The people I read who kept root with OTA rootkeeper were using SuperSU after JB update.
So unlock, downgrade, root and use SuperSU, use OTA RootKeeper and then re-upgrade. This however isnt a guarantee. =/
My tablet was not unlocked and I had just stock with root. I wasn't using SuperSU before the JB updates. I used Superuser and restored root with OTA Rootkeeper after the update. Once I shut down the tablet (on Thursday night) it forced me to do a full restore after bootlooping when I turned it back on at work Friday.
Once thenrz posted his thread, I noticed I had a partial root, I had Superuser.apk in system/app and I could see su in /system/bin/ but no su-backup. I used the FileManager not ES Explorer to look for these. Once I saw I had both of those, I went ahead with adb to push the files with the commands and I gained root access again.

The thing that puzzles me the most is that I was using superuser elite not SuperSU when I used OTA Rootkeeper. Rootkeeper didnt offer a root restore after OTA update.
Even now though in ADB Shell if I type SU I can see in the superuser log it instantly shows SHELL Allowed. The prompt doesnt change to # though and I can't remount as RW etc... so I am stuch there.
If I open terminal on the device and type SU the log showed denied so WTF?

If you have the files in there (Superuser.apk in system/app and su in system/bin) it should work for you...are those file there?
Nope.
I'm just puzzled at the "Allowed" in the log?!
In /data/local/tmp I do see a file _su what is that? If I try to execute the _su I get permission denied.

That is puzzling. You just might have to unlock, downgrade, root and use SuperSU, use OTA RootKeeper and then re-upgrade. but i thought if your tablet had a unlocked bootloader then you could not get the update.
Hrm, found SU in the /system/xbin folder
and I kept the original dlpkgfile from the OTA update. I just don't want to void the warranty, the thing is a week old =/ Rather annoying.
_su is a file used by one of the root methods out there. (bin4ry's i think) I think that's the su that is restored to /system by the exploit? Anyway, _su can't get us anywhere in this case. The lid on JB seems pretty tight.
ALSO! Make sure to keep a backup root with voodoo or super su after completing this guide! I have lost root after about 24 hours (VERY WELL may have been my own fault... too much poking around maybe?) Anyway, better safe than sorry!!!
I'm in the exact same boat as you. I had root before the JB update. I also had voodoo rootkeeper installed and backed up. But now when I go into root keeper, I don't even get the option to restore.
I can't get the # at the prompt, can't mount /system as rw, and only have su in the xbin directory. Grrr....
I don't want to unlock/downgrade/root/upgrade/reroot only to be in the same position I'm in now.
In adb shell, copy and paste your output from $ ls -l /system/xbin
I am curious to the permissions in your case
shell@android:/system/xbin $ ls -l
-rwxr-xr-x root shell 59760 2012-09-28 07:19 dexdump
-rwx------ root root 5380 2012-09-28 07:19 ps3bttest
-rwxr-xr-x root shell 23592 2012-09-28 07:19 rfcomm
-rwxr-xr-x root shell 91980 2012-09-05 22:29 su
Can you do the same to /system/bin? Are you getting permission denied when you type su?
Same Boat:
shell@android:/system/xbin $ ls -l
ls -l
-rwxr-xr-x root shell 497964 2012-09-26 21:25 busybox
-rwxr-xr-x root shell 59760 2012-09-27 11:18 dexdump

-rwxr-xr-x root shell 380532 2012-09-26 21:04 su
This is my output when I type SU
shell@android:/system/xbin $ su
su

ls -l
-rwxr-xr-x root shell 497964 2012-09-26 21:25 busybox
-rwxr-xr-x root shell 59760 2012-09-27 11:18 dexdump

-rwxr-xr-x root shell 23592 2012-09-27 11:18 rfcomm
-rwxr-xr-x root shell 380532 2012-09-26 21:04 su
This is my output when I type SU
shell@android:/system/xbin $ su
su
1|shell@android:/system/xbin $
Can anyone comment on the ownership of su and busybox by shell and not root? If you use a busy command, do you get output? ( busybox mount will show a bunch of info)

Thank you for posting all that! I find it really interesting that our root setups are totally different (I assume different root method, choice of maker where to put things?) yet both of us lost root (but I still had # after wipe). Good info for the future in terms of protecting root from OTAs.
Heres my xbin:

I thought I had lost root and could not use the methods described here. I could not get the root prompt as per the instructions. However, I had SuperSU installed and found that if I disabled Superuser in the settings for SuperSU (it was enabled from before the OTA update), and then enabled it again (unticking and ticking that box in the settings for SuperSU), I had root restored. Lucky too since I found that Voodoo OTA rootkeeper did bugger all.

29This will only work if you can access a root prompt (#) in adb shell! THIS WAS DONE AFTER DOING A WIPE FROM THE VOLUME DOWN MENU WHEN BOOTING THE PRIME! I do not know if this will work without the wipe, but it very well may. Maybe someone more knowledgeable can chime in here.
It may be possible to restore from a su-backup if you have a su binary still in /system/bin or xbin. Even if you can't access a root prompt (#) by just typing su, read starting at page 6. Places to look for a su-backup include /system/ /system/usr/we-need-root/ and /system/bin/
I have a batch script in the works that will determine if you can re-root and take the appropriate steps to do so if possible.
I had to do a voldown wipe after my update to JB. My prime would reboot after 5-10 seconds into the homescreen after boot. After wiping, I thought for sure my root was screwed until a new exploit was found.
I accessed my device through adb, and realized that I could invoke a root prompt using the su command at the $ prompt. Using ES file explorer, I could see su in /system/bin/ but no su-backup or superuser.apk in /system/app/.
I tried simply installing superuser from the market, but it did not work. The busybox installer would not work, either.
ATTACHED ARE THE EXACT THREE FILES I USED. I do not know if using different version will affect the process!
Here is what worked for me:
1. adb shell
2. su
(# - you should see this now! This will not work without this specific prompt!)
3. type 'exit' press enter, and then 'exit' again. You will now be back at the regular command prompt.
4. adb push C:\(location of attached files)\superuser.apk /data/local/tmp
5. adb push C:\(location of attached files)\su /data/local/tmp
6. adb push C:\(location of attached files)\busybox /data/local/tmp
7. Access the adb shell again, and type su
8. chmod 644 /data/local/tmp/superuser.apk
9. chmod 755 /data/local/tmp/busybox
10. chmod 6755 /data/local/tmp/su
11. mount -o remount,rw /system
12. dd if=/data/local/tmp/Superuser.apk of=/system/app/Superuser.apk
13. dd if=/data/local/tmp/busybox of=/system/bin/busybox
14. dd if=/data/local/tmp/busybox of=/system/xbin/busybox
14a. Chmod 755 /system/bin/busybox
14b. Chmod 755 /system/xbin/busybox
15. Reserved
16. busybox rm /system/bin/su
17. busybox cp /data/local/tmp/su /system/bin
18. type su once again to assure you still have access to the # prompt
18a. Chmod 644 /system/app/superuser.apk
18b. mount -o remount,ro /system
19. type exit, and exit again, returning to the regular windows command prompt.
20. type 'adb reboot' (without quotes)
NOTE - you will not need to install the superuser.apk app in the normal sense. It will be installed upon the reboot as a system app automatically!
21. Once your prime has rebooted, go download root checker basic or the like from the play store. Open it, and wait for your superuser prompt!
22. Get the busybox installer from the play store as well, and use that to get the newest version of busybox.
23. Get SuperSU from the market. It seems to be the safest method to keep root with JB...
ALSO! Make sure to keep a backup root with voodoo or super su after completing this guide! I have lost root (VERY WELL may have been my own fault... too much poking around) Anyway, better safe than sorry!!!
Thanks to daymz from the debugfs thread in development for the basic instructions of what needed to be done!! And also thanks to all before me who got us root in the first place!
I will answer questions to the best of my ability. I am not a developer and do not try to present myself as so... I can tinker with the best, and after losing root, I set out to see if I could figure it out!
Changes made as per tsmt9715I have fellow this method and it was failed at step 16 in my case because of the permission issue but I managed to make it move and regained the root. The details of the issue as below.
Step 16 failed because step 13, 14 which will copy busybox to /system/bin and /system/xbin with a wrong executive permission.
To correct in my case: after step 13, 14 follow those steps below:
- chmod 755 /system/bin/busybox
- chmod 755 /system/xbin/busybox
- skip step 15
- continue steps 16, 17, 18
- chmod 644 /system/app/Superuser.apk
- continue step 19, 20, 21, 22
Then you will get your root back, it worked in my case. Good luck guys.
To the OP, please verify and update those steps if necessary.4I just figured something out. I found a su-backup in /system/usr/we-need-root . I have lost root again since making this guide. My permissions were screwed up on su. I was able to restore root by doing the following:
Code:adb shell: $ cd /system/usr/we-need-root $./su-backup; su (that is a semicolon immediately after the ./su-backup) # mount -o remount,rw /system (do what needs to be done) #exit ...
su-backup must have permissions as such: (get permissions by typing this into adb shell: ls -l /system/usr/we-need-root ) If you get an error, than this specifically won't work for you.
Code:Required su-backup permissions for manual root restore $ ls -l /system/usr/we-need-root/su-backup -rwsr-sr-x root ...
basically, if you can find a su-backup with proper permissions (and cannot restore root with voodoo or supersu), you can manually use that to repair your root access configuration. Maybe this is well known... but to those who don't this could be useful.1
As far as I know, unless someone is keeping a HUGE secret.
I should mention the unlocker from ASUS but i don't know if anyone has tried it on JellyBean1Same Boat:
shell@android:/system/xbin $ ls -l
ls -l
-rwxr-xr-x root shell 497964 2012-09-26 21:25 busybox
