[Q] Tf700 Root/Superuser stopped working?? - Asus Transformer TF700

All of a sudden the superuser on my TF700 stopped working; all rooted apps are now being denied superuser status. Worse, Superuser won't reinstall, and Rootchecker.apk tells me the tablet isn't rooted anymore. Voodoo OTA rootkeeper still has the saved root files, but won't reinstall them on account of the borked superuser, I'm assuming.
I should add that NONE of the available Superuser apps will install; not the original Superuser, Koush's Superuser, or SuperSU.
So I tried the whole rooting procedure by trying to downgrade to ICS. But although the tablet sees the file it won't install it; on reboot all I get is the dead Android with a big red X. When I tried it a second time, the tablet now doesn't even acknowledge the presence of the downgrade file.
I need help here. I just rooted this tablet but never installed recovery (wasn't interested in unlocking it at the time). How do I proceed from here?

Hard for me to understand where you're at exactly.
Did you actually boot into ICS before trying to re-root?
Sometimes when SuperSU updates you will have to go back into the application and reset permissions for all rooted applications.
If you can boot and if the previous SU is still there go into settings for the tablet and uninstall any updates for SuperSU then try to reset permissions in the app.

Go into settings -> recovery- factory reset. Try one or both if needed:
1. Download the full Asus ICS .30 zip, verify MD5 (ensure file is not corrupted), unzip the file then copy the unzipped file called US_epad-user-9.4.5.30.zip to the root of your internal, boot into stock recovery and let it flash.
or
2. Reformat your micro sdcard.
1) Download and unzip US_epad_user_9_4_5_30_20120907_UpdateLauncher.zip and got US_epad-user-9.4.5.30.zip. Copied it to root of microsdcard, reboot your tablet and check your notification for software update.
or
3) unzip US_epad_user_9_4_5_30_20120907_UpdateLauncher.zip and got US_epad-user-9.4.5.30.zip. Rename this file to EP201_768_SDUPDATE.zip then copy this to root of microsdcard. Power off your device, boot into recovery by hold power + vol down buttons, when you see white text release both buttons, you should see 4 icons. The icon "RCK" should be highlighted by default, just wait a few seconds and it should start flashing.
then renamed US_epad-user-9.4.5.30.zip to EP201_768_SDUPDATE.zip and

I finally managed to get back to ICS, then ran the rooting procedure. However, it always failed when it came to testing Superuser. Tried it four or five times. Then I tried installing the other Superuser apks. Every last one of them said the su binary needed to be updated, but every one of them failed to do so.
That's where I am right now. Unrooted ICS.

Thanks for the info. I managed to get back into ICS (see previous msg) using your number 1 (took three tries) but I can't complete the root procedure because for some unknown reason superuser won't install correctly.

Is there a previous version of SU installed or leftover?
See if it's still in running apps under settings.
If you're on ICS I'd try a factory reset and go from there.

After you flashed superuser, did you launch the app?? you need to launch the app and it should prompt to update, do the update. Once done now you can test for root.

I did launch the app and it did tell me the su binary needed to be updated. So I told it to go ahead with a normal install. Installation failed. Also tried the SU update fixer from the play store, and that failed as well.

You need to reflash your ROM... I get this often. I'm maintaining 6 devices for my family.

Just do a factory reset, then follow my number 3 post. Also make sure you verify MD5 on the ICS .30 rom before flashing.

Well, I tried, but when I rebooted with the power and vol-down buttons, I only got an "Android" icon and something else to its left, no RCK at all. The pad rebooted eventually and I was stunned when Superuser started working! I immediately ran Voodoo OTA Rootkeeper, then let the tablet update to 4.1.1. I then ran SuperSU and it said the su binary needed to be updated. I told it to do a normal install. "Installation failed." Said bad words in several languages and tried again. Update of SU binary succeeded.
Restored root. Success. Now restoring last Titanium backup backup.
I'm still worried, though. The symptoms would seem to point to flaky or at least unstable flash memory. What do you think?
I gotta decide whether to get a Samsung Galaxy Note tablet (7-inch) or the updated Nexus 7 tablet when they come out. I don't trust this TF700 anymore..

I have the same problem, but didn't downgrade!
I have the same problem, except I have not tried to downgrade.
The first problem I noticed after the OTA update was that Bluetooth simply would not turn on. Going through the steps to fix this problem I noticed that OTA Rootkeeper "kept root", but any time I try to use su, it fails to work.
I managed to fix bluetooth using ADB, but I am still left with su and superuser that do not work. Is there a way to fix this from ADB by twiddling with permissions somehow?

Seems like now there is a way to root if you already on JB, no need to downgrade to root.http://forum.xda-developers.com/showthread.php?t=2228613 .

The su and busybox binares and SuperSU.apk get installed, but any time I try to use root permissions I get an Access/Permission Denied error. I used the root method you gave me and everything seemed to work properly... The only thing I see that may be wrong is that the su binary is owned by "root root" rather than "root shell" like everything else is. If I try to chmod it using ADB I get permission denied errors.
Now I'm just frustrated and don't know what to do. Nothing seems to work with the 4.2.1 stock ROM. I don't want to have to unlock the bootloader because I chose not to void the warranty (didn't enable nvflash) when I first got my tablet.
I think I'm just screwed at this point. Does anyone have any ideas? I did manage to get bluetooth working, but I still can't seem to get my TF700 rooted. Without root, Titanium Backup can't restore my apps...

Since motochopper has the ablility to root JB, you should remove superuser root (open supersuser and select remove root then reboot), then re root using motochopper if needed.

I finally managed to fix the problem, though I did it the long way...
I downloaded the stock 9.4.5.30 US ROM zip file, extracted it, renamed the extracted zip file to EP201_768_SDUPDATE.zip, and copied it to a microSD card. I booted to recovery and installed the zip file. Once it was installed, I went to Settings --> About Tablet --> System Update --> Check Update. I had to update this way twice to get to a clean, stock JellyBean 4.2.1 (US_epad-10.6.1.14.4-20130329).
Once I was up to date, I ran the Motochopper root tool and it worked! I have no idea what it was about my tablet that prevented su from working after the update to 4.2, but thanks to everyone for your suggestions.

Can you tell us what the owner,group and permissions of the /system/bin/su binary are now ?

Oh, sure!
After a search through my PATH, I've found that 'su' no longer lives in /system/bin, but in /system/xbin, with busybox and dexdump and every POSIX command you can think of symlinked to busybox. It is owned by root:root.
I guess that's just the way the JB root method does it...

[Q] Is a Partial Root possible?

Please excuse me if this has been covered elsewhere but I have done a search and can't find anything that applies to my Transformer or the problem I have.
I used Razorclaw to root my Transformer when it was on Honeycomb, and Voodoo OTA rootkeeper to retain it when I upgraded to a later version of HC. And then again when the first ICS update came out. However when the .17 OTA came out, in my haste to try and fix the problems that came with the first ICS update, I hit 'install' without thinking. I should have made sure voodoo had a fresh backup and temporarily unrooted the TF (as I had done on previous updates).
So after the update I checked with both Titanium Backup and Voodoo which indicated I did not have root. I selected the 'restore root' option in Voodoo and it then indicated I had regained root access.
So now the three apps that I had granted root access prior to the upgrade (Titanium Backup, ES File Explorer and Voodoo) still have root access, but whenever I try a new app that requires root it says I don't have root. And checking in Superuser the 3 apps above are listed as allowed, but no other requests are even logged.
So my question is how can I have some apps that require root working, yet new requests are denied? And is there a simple way to fix it? I don't want to uninstall Superuser in case that loses me root completely (and permanently) and when I try to update Superuser it fails to gain su and stops.
Edit:TF is running Stock firmware, just rooted.

This did not fix it I'm afraid, but thank you for your suggestion. It's almost like Superuser is frozen and won't allow anything else root access. I see there is a 'Superuser Update Fixer' App on the Market (oops I mean Google Play Store) but I'm not sure if that will solve the problem I have as it seems to require root access to work...

I don't think you have root. I had same thing happen, literally almost exactly and its because I did not have proper root. Use vipermod to get root back and you'll see everything will work like normal
Sent from my Transformer TF101 using xda premium
Thank you both baseballfanz and eminembdg (I pushed the thanks button) Vipermod Option 1 did the trick. I now have full root access restored. The biggest problem I had was I couldn't find any Win7-64 ADB drivers so had to go and pull the old Win7-32 laptop out to get everything to work properly.
Still can't see why I had partial root permissions though. I thought it was all or nothing. Kind of like being a bit pregnant.

Zeepad comes rooted already, at least mine did...install superuser from market and any app that needs root permission, if your able to grant such permissions your rooted. Sorry i cant remember the command for adb or terminal emulator to get this answer quicker...

My daughter just got one of these devices for Christmas, as well. I saw this post as well and thought "Great, I don't have to do the part" so, I installed SuperUser, when I went to update the su binary, which was shown as "Legacy" it got all the way to where it needs to remount the / file system as rw, and to my surprise, it wont remount. Another thing I noticed was that even though it does have su installed, I can't get to the point to where the app even asks for root permission. I tried to update Busybox, as well, and it wouldn't let me even do that... The version which is installed to the tablet appears to be 1.18, but when SuperUser goes to update the su binary it reports back as being the same as the installed version, which I know for a fact that it is not. So while I do in fact have root, it seems to only be a partial root. Anyone willing to throw around some ideas as to where I can go from here to A) get the / file system to remount rw, and B) get SuperUser, an updated su binary and an updated Busybox installed so that I can a full root going and get down to business to installing CWM and CM10 installed and running on here for her.
Any help would be appreciated,

all zeepads come prerooted and shouldnt block u from updating or to have root access (download root checker) from market
Ur Binarys Should Still Update And Say Current If U Download New Binary Just Wont Show Up Till Reboot
If u Want To Stop This Error While Not Having To Reboot Everytime
Ya This IS Annoying to Do Everytime But Simple solution
THis Proplem IS Do To The Tablet Having A Stock Kernel That Doesnt Allow System Read/Write Access
This Is Why SuperUser Fails Cause It Needs Write Access To The Devices File System...(system/xbin/su)
Which means to Remount system after updating to take Affect And Most Stock Devices Do Not Allow This
so if u updated and it said current version ur ok this is to prevent anymore errors in the future
superuser can have different error witch mean different things just cuz u get one doesnt mean
they didnt take affect but remount of system is the most common error check superuser faq
1.Download Mount System R/W App From PlayStore And Install And Open.
2 .Allow Root Access To The App Then Select Mount System R/W Button
3. Press Home Button And Navigate To SuperUser App And Then Try Updating Binary
This Method Should Work For You
Hope This Works For You
As for cwm and cm9/cm10 it depends if u have a8 or a10 device a13 are not yet supported

Sorry for bringing up an old thread, but I got the a13 and was wondering if anyone was making a cm9/cm10 rom for it as well. I have the a13. I tried to Google and can't find any info about any custom roms for this device.
I used kingRoot version 4.1 Any newer version would not root it.

You have to root this phone via RECOVERY. Use attached file and UPDATE FROM SDCARD.
Also you must not update (after recovery root) SUPERUSER app via android-market to newer version!!! If you'll do it, then it all comes broken. And you have to do it once again.

OK, that's no problem.
Attached package contains few another packages....(update.zip is the same like I uploaded here before)
1. Try to use "Superuser-3.1.3-arm-signed.zip" (this should be enough but I don't know why it isn't)
2. Reboot
3. Look at Superuser app
4. If Superuser app doesn't work then use "update.zip" once again
5. Reboot
6. Look at Superuser app
7. Now it should be working if not you can update Superuser app from market and try above procedure once again
Root this phone is really long term job. But never give up!! This phone is useless without root. I have been rooting this phone more then week.
Good luck and post if will you be successful.
just wondering since you have some experience with the phone.is there a custom rom for this phone or just the original one?

[Resolved] [Q]Need Help with Xperia Miro lost root access

Hi All,
I have screwed up my android which was perfectly fine with a perfect root. Please help me to restore the root access !!!
Here is my problem description:
I have a Sony Xperia Miro which was perfectly rooted.
Model : ST23i
Android : 4.0.4 ICS
Build : 11.0.A.5.5
The root verification using app 'root checker basic' was successful.
Now I had few of my company apps and bank apps which wouldn't work in rooted device. But I never wished to lose my root status. So I was searching for the ways to hide root access from these apps. I even came across apps exclusively built for this purpose (hidemyroot/OTA root keeper) But due to some bad comments about these apps, I decided to try manually
The idea was to fool the apps when checking the root access.
At first I renamed the super user apps at the location /system/apps. to some invalid file(super.txt)
This did the trick for couple of apps which weren't working before in my mobile. However couple of apps were still failing.
The next thing I did was renaming .su to ku in the below location /system/bin/.ext
Then I verified Root Checker Status, still it displayed "u have root access"
Then I went to /system/xbin and renamed the following.
.su to ku
.busybox to busyboxk
.dexdump to dexdumpk
Then I tried Root Checker Basic again. And got the message "device don't have proper root"
But still my apps were not working. Then I did the most foolish thing which was restarting the device.
BAM.. !!!! I lost my root access permanently. Now I don't have superuser app. And I m not able to use 'Root explorer', to rename back the files to its original state.!!! And most ironic thing is my company app still saying I have root access. I tried after deleting its cache and data. The result was same !!
How can I restore my root access ? Please help
one update
Since I renamed the superuser and superSu applications, I couldn't use them.
Today I installed both of them using package installer.
But they doesn't seem to work as they can't find su binary installed

The same thing happend to me awhile back :/ If you want to save your apps use titanium back up or app backup & restore and add a custom recovery like cwmr so if this happens agen you wont have to reroot. if you are still having problems with your apps for work boot your phone into recovery and go to advanced then fix permisions if you have any other questions or any problems just let me know.
oya dont backup your superuser and supersu on your app backup sence you renamed them redownload your superuser if it dont come with your root program that you are using. and dont use supersu unless you really need it

HI,
I prefer to fix the issue in the same way it's been happened. The issue occurred when I renamed the
Su binary manually. I was trying to find ways to rename it back. So here is what I am going to try...
1. Pull the files using. Adb to PC and rename and push it back to phone.
If this doesn't work,
2. Install CWM and flash the zip file to install su,busybox,superSu
If this also doesn't work,
3. Reroot the phone
Unfortunately I can't do any of this right away. I will try this as soon as possible
and tell you which method worked for me.

:good: Plz do. I should have thought about pulling them. Im writing a guide on adb and didnt think about that lol guess my brain is fried from 18hr shifts and coming home and getting on here lol. But any ways after you pull them just replace them with new files insted of renaming them it would be less of a hassle. I would still install cwmr on your device

Solved the issue Finally !!
I was trying to pull the renamed files to PC(Windows Xp SP3) using adb. But I find lot of trouble setting up adb in Sony Xperia Miro. I updated my device by using Sony PC companion. Still couldn't get my device detected in the command 'adb devices' . Then tried to update google usb drivers. It didn't work at first, but I could install google usb drivers after changing android_winusb.inf file to include my device ID.
But even after I could get my device show up in command 'adb devices', I couldn't pull/push files. For some strange reason, my device was disconnecting continuously and each time I have to stop adb.exe process and restart to get my device connected back. And I finally gave up in the process.
Then all of a sudden it clicked me that why don't I use terminal emulator installed in my phone. But the biggest road block was to get root access. Root access will be given if you execute 'su' command in 'adb shell' . But I renamed the su binary. what do I do!!
Then I decided to give it a shot that executing the renamed binary !! (I had renamed su to ku). So I simply gave ku in adb shell. whola!! It worked. I got root access.
All I need to do was, change the permissions (using chmod) and rename the files back(I used root explorer) to correct names.
And I am done I got my ROOT BACK !!:good::victory::victory::
Later I updated my su binary and all is well in my device now. And what more, I found way to get my company apps work in my rooted mobile. I installed OTA rootkeeper and temporarily disabled root. Guess what it was still not working.
Then I tried my old stupid trick again (together with OTA temporary unroot). Rename SuperSu in /system/app .
And it worked !! But I won't be stupid again to reboot my device with this settings. And even if I did accidentally, I know what to do.. !!
Thanks everyone...

That's Awesome :highfive: I'm glad the hear that you got everything working correctly and with your company apps too. :victory:
Thank you for sharing with me and everyone. You never know if some one out there is having the same problem and this could really help them out one day.

[Q] Lost root access?

Hi guys android newbie here! My friend rooted my Nexus 5 and it was working fine for a couple of weeks. Yesterday I tried to open SuperSU and it didn't work! Other apps that required root didn't work either.
I have been looking around and it seems OTA updates may have screwed up my root. Every time I try to open SuperSU it says: "There is no SU binary installed, and SuperSU cannot install it. This is a problem!" If you just upgraded to Android 4.3 (I have 4.4), you need to manual re-root. Consult the relevant forums for your device!" I have used root checker by joeykrim and it says "Sorry! this device does not have proper root access" (to confirm my root is busted).
My question is, is there any way to fix this without re-rooting? If I have to re-root, can I just directly re-root it again using something like Wugs rootkit?
Thank you very much in advance!
Just flash the newest version of supersu and you'll be good to go..... http://download.chainfire.eu/370/SuperSU/UPDATE-SuperSU-v1.80.zip
go to the play store, find supersu, install/update it, open tbe app and update your binaries.

I've tried to insyall /uninstall, wiping the cache and data with no luck. Right when I open the app the supersu binary problem comes up and I can't even get into it!

I can install/update to v1.8! I just can't open it. Gives me a "SU binary not installed" when I do!
Did you install/update from the playstore or flashed the new update?

Sorry if this is a stupid question .. but how/ do I flash this or what program do i use?
My friend helped me root it so i have no idea on how to do this @@ Very sorry.
Hmmm... from the link I posted in one of my last post, you can just use a useful app called "flashify" and flash it that way (the easiest way) but you need that file that is in the link obviously to do so haha. So afterwards when in flashify you'll get 3 simple options, boot image, recovery image, and zip file. choose zip file, go into your downloads folder from the file explorer from the app (which it should be there if you downloaded it off your phone) and let the app do the rest

Ok so I can't open flashify either. It also says I have lost root access and my superuser is busted. I have attached a screenshot!

Of course, you don't have root access, silly me lol Well guess we'll have to do it the hard way (it's not really that complicated) ok read carefully. Power off your phone, afterward hold the power and volume down buttons which should get you into the bootloader, cycle trough the options with the volume buttons and when you see recovery mode select it with the power button, now depending on which Recovery you have you'll have to choose the option that says install or install from sd card, again, depending on which one you have this will be slightly different. After doing i believe the paths will be the same, chose 0/ then look for the download/ folder which you should have that supersu.zip file, if you're using twrp recover it should be touch screen and you simply select it and swipe to install, if you're using cwm (which i do) you'' have to scroll with the volume buttons and select the file with the power button to install. I hope I was as clear as i could be, good luck
after going into recovery mode, there is just a android robot with his chest open and an exclamation mark! can't proceed after that.
Ouhhh you don't have a recovery then, do you have adb or any kind of toolkit?
I have wugs toolkit. but every time i try to do anything at all on it. It says ADB device not found? That seems to be preventing me from doing anything as well.
Do you have the adb drivers installed or/and usb debug turned on in developer settings?
how/where do i install adb drivers? I have not done so, and i doubt my friend did it when he rooted.
I do turn on usb debugging when i tried to unroot/root on wugs toolkit
In wugs toolkit it has a walk-through on how to do so, i suggest you use the RAW drivers option
I must be blind to not have seen this before. Thank you very much for your help I'll let you know how it goes!
