I lost root- perhaps thru flashing new recovery?

I rooted my Zoom wifi long ago. Flashed all the various Tiamat kernels and followed bigrushdog's 3.1 update with no problems. I recently flashed the CWR RC 4 over the updated 4.0.1 version in Rom Manager. I now see that all my apps requiring root don't work. I have Super user app but don't get the request to grant su anymore. I tried upgrading Super user within the app but it fails and writes a zip update to SD card which is supposed to be flashed through Recovery but doesn't (I suspect because the file is a 0 byte file!).
Any suggestions on how to get root back?
[Solved]: Seems it was a result of trying to upgrade Superuser that I lost root. See the last post below and the solution Almighty1 offers. It worked and I have root back......

There is a problem with the latest recovery version in Rom Manager. The recovery from solarnz is probably not at fault, but maybe the interaction of the two. You wil lneed someone with more knowledge than me to help you get root back, but this issue really needs attention. There are several updates to apps that seem to be breaking our Xooms, and there should be pinned warnings or the developers should be making everyone aware of these conflicts as soon as they find out. I had problems and I'm sure a lot of other folks have have problems with these incompatible app updates as well.

Thanks for that. It almost seems like Superuser is "degrading" in the sense that I had a number of apps reflected in the Superuser app as having been granted root (but not Rom Manager). However, I couldn't add new apps to it. And when I cleared Superuser data and reinstalled it, none of the apps that required root (and which had worked before) would work.
I also think that the writing of a 0 byte zip update file by the Superuser app indicates a problem.
I suspect the solution may lie with fastboot and re-pushing Superuser and CHMOD(?) file permissions but like you, I am nervous to play with these sort of things. My Xoom is working and until I have the need to change the ROM, root doesn't matter to me....

after reading this I checked and also had lost root. I had not checked after after flashing 4.0 in rom manger. Superuser was still there but my apps did not have access. I tried flash a new recovery, reflashing Tiamat nether worked. Anyway from adb
adb remount
adb push su /system/bin/
adb shell
chmod 4755 /system/bin/su
exit
adb push Superuser.apk /system/app/
I then rebooted and had root... updated Superuser as I had an older one in my platform-tools and all is well I then flashed the lastest recovery in rom manger and still have root.
Hope this helps

Thanks. I will give it a try this evening when I get back from work.
Also found this: http://forum.xda-developers.com/showpost.php?p=14643716&postcount=340 which seems similar to your solution.

This is why I hate CWR. I wish we had Amon RA recovery.

[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.

Look to see if you SU in system/xbin if not look in system/bin and copy SU from there to system/xbin

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...

Try running ViperMod (option 1) again to get full root.

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

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.

Help with wiping and/or reinstalling busybox

Hey guys and gals,
I've got a 7.7 on stock ROM rooted using the original root method the day I purchased the tablet. I've been using my tablet happily for over a month now.
Unfortunately, late last night I opened up Google Play and started updating all my apps, including Busybox by stericson. There was a new busybox version out (1.20.1) and I decided to install it using "Smart install." I'm not sure if it tried to install to /system/bin or /system/xbin but after the install I saw the app give me an error message explaining that the install was unsuccessful. Anyways, now a lot of my root-requiring apps including Titanium Backup Pro is not functioning at all. It seems that my BusyBox installation is corrupt.
I tried using BusyBox Pro by stericson to uninstall but the corrupt busybox seems to have prevented a proper uninstall, so it still lingers. I downloaded JadeEyedWolf's root.zip from his pinned "Root" post which includes SU & BusyBox thinking that installing the root.zip from CWM Recovery would over-write the corrupt busybox. After flashing I rebooted the tablet and I still got the same corrupt busybox issues.
Anyone have any suggestions?
Thanks!
Edit: The corrupt busybox causes the Wifi to show Error when I try to turn on the radio. Not that internet is vital in repairing the tablet, but I've worked around it by tethering Bluetooth internet off of my OG HTC Evo 4G. It's strange though - I can peruse websites and view the items in the Google Play Store but it will never actually download, though the "Downloading --- " bar does display.

I had the same problem, stock rom as well. If you check the reviews for Stericson's Busybox on Google Play, the two top ones a few minutes ago both mentioned the same issue.
Trying to root again and reinstalling Superuser didn't help, neither did a factory reset (manually salvaging settings and data was a pain too).
Re-flashing the original rom fixed it, following the guide at http://forum.xda-developers.com/showthread.php?t=1469635
I switched to JRummy16 Busybox installer and it seems to work.
Surprising that no one else here mentioned the problem ...

Try this fix.

To be more specific: BusyBox installer 8.0 replaces /system/bin/sh and /system/bin/ash binaries. I don't have any idea why would it do that (considering that I specified /system/xbin as an install folder), but this quick fix restores original ash binary (and sh as a symlink to it).
Installer 8.1 and above has this bug fixed.

Had the same problem with busybox and had to re-install the rom. What does this fix do?

Thank you so much it works well now! You're a life-saver ginkage. Should I keep the stericson busybox 1.20.1 original install or should I use the busybox installer to install a fresh copy of 1.20.1 in /system/xbin?
Thanks again!

Personally I always use /system/xbin, so that some custom kernel (like CWM) could use /system/bin if it wanted to.
BTW, the BusyBox installer bug was fixed in version 8.1, and current version is 8.2, so you should update it anyway. I was wrong to mention "1.20.1" version. Post edited.

Hi guys,
First of all, I want to apologize sincerely for the bug that my application introduced in 8.0. I didn't catch the bug because my device wasn't affected by the bug.. (I always test my app myself before releasing..yet I still miss things due to devices file structure being so different.)
At any rate, the bug was that the application symlinked all applets to Busybox. Normally, this is done if you use smart install and change the settings manually. By default smart install will not overwrite applets that are not already symlinked to Busybox.
This was not a problem with Busybox 1.20.1 but was a problem with my application and how it performed the install.
Again, I am very very sorry that this has occured, as a result I am scouring the web trying to find people with the issue and help them resolve it.
If you have this problem, it can easily be fixed by reflashing your current rom. you do not have to wipe or clear any data. Once this is done, you can download my installer, version 8.1 or greater and upgrade busybox as normal.
Please let me know if you guys have any questions.
Best Regards,
Stephen - Stericson

I too had the same situation, updated busybox then noticed something was awry when hidebar wouldn't work. My issues go way beyond broken root and WIFI, I've also been getting constant reboots. I was just about to re-install the stock rom until I read about the possible udate.zip fix. I'm very interested in how to apply the zip (I don't have CWM) being that i do extensive customization (with no backup, I know, I know) and I'd hate to re customize everything again. If I can get things right the first thing I'll do is install CWM and perform a nandroid backup.

you don't need CWM, just copy the fix onto external storage card,enter recovery (PWR + Vol. up Buttons) and apply the update from there. just fixed my tablet this way

Thanks for posting this, I'm in love with my 7.7 once again.

Appreciate the response stericson. I had purchased your Pro version but even after I fixed the uninstall failed and it also did not detect superuser permissions even though SU gave a notification that Busybox Pro was granted superuser. All other root-requiring apps work. Had to refund the Pro purchase though

No problem. there seems to be an issue with the application detecting root sometimes, that's why you can still try the install.
I'm looking into this issue, it just started showing up so I am not sure what is going on.

Really appreciate this fix. On the verge of wiping out everything....
But decide to see if its busy box since its the last thing i install before all this happens....
Just to note that uninstall busybox also doesnt solve the issue...
so need to fix.

I had a lot of problems with root permissions not being granted by Superuser app. Recently I have tried SuperSu from the market and uninstalled original Superuser app (important to follow the instructions for the App! ).
My main problem was that ntfssd was not granted root permissions at startup, so I had to start it again manually. With SuperSu it is no problem. Also I use Busybox and successfully updated to the latest binary recently.

Thank you so much for that, I had been driven crazy and had also gone through a factory reset to try and get my device back working, to no avail. Can I ask where you got the ash you're including here? It worked for my Samsung Galaxy Tab 7 Plus, on 3.2, but is it a generic enough file that it can be dropped on nearly all Android devices without any issues arising?
I only ask out of curiosity and understanding the system more.

[Q] [SOLVED] Problem with root since update to Stock JB 4.1.1

Hello,
I used "OTA RootKeeper" too "save" my root, and then updated my phone.
I had to re root manually, and since this moment when I try to install busybox or to update su binary my phone reboots.
I tried to manually remove the root (by removing the Superuser.apk and su files), to wipe /data, dalvik_cache, cache etc...
Nothing seems to solve the problem
Does anyone have an idea?
Thanks for your answers!
(Sorry for my English I'm French )

Yep, the jb update has a kernel that write protects /system, at least for the One x and Droid DNA

Is that to say Hassoon's toolkit won't work on a JB updated device?
I've just updated and I'm regretting every minute that I've used it since....

That means root doesn't really exist on jb.. even if you install su, any changes made will be undone at a reboot

Actually the phone gets rooted fine busybox is installed, checked with Root Validator after several reboots, but it seems system partition, or something else is not mounted with write privileges.
S-On ?? Maybe? I'm not a HTC guy....

System is write protected.. due to the kernel, you need s-off or a different kernel, and seeing as there is no kernel source, ICS or aosp are your options. Try making a folder in /system, it should be gone after a reboot

But the files I create from TWRP recovery aren't removed after a reboot. The Superuser.apk is still here after a reboot.
So it seems that I can write to /system from recovery.
Do you know if there's a flashable zip for busybox?

I flashed the one in the JB discussion thread... I think it contains Busybox and SU and it works like a charm... It's a problem but there are workarounds...
For me everything works as long as it doesn't write data to system .
AdBlock works, it gets SU rights but it cannot write the hosts file... I will try later to use the symlink solution...
Su + Busybox
WAY LATER EDIT:
System Partition RW on JB stock roms via kernel module

I just tested it and everything I used before on my phone is working again and no more unwanted reboot
Thanks a lot !

I sent a PM to TeHashX, he was asking for review on his work, and also thanked him... His work could benefit others... so make his post more visible!
Remember, that because of the kernel, AdBlock still doesn't work, basically every program that modifies /system works but only apparently. I could use Titanium very well, only Integrate in Rom option doesn't work so take care using "ROOT" on HOS JB.

[Q] Tf700 Root/Superuser stopped working??

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.

See if it's still in running apps under settings.

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.

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?

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...
