Hi,
I used to root the tablet successfully. But I found I did not have the root access grant this morning after consuming the power.
So I tried to root it again, but I got remount failed when executing NookandZergy.bat.
remount failed: Operation not permitted
Is there anyone could help me?
Thanks,
Kevin
its weird that you loosed root , first check if you are still on version 1.4.0, if so then try first using the unrooting script method and then root again, if not and you got the 1.4.1 upgrade silently then you will have restore stock(Go back to 1.4.0) and start from scratch, if you previously had a titanium backup of your apps then you good if not do it now and copy your titanium backup folder in to your pc.

Thank you for your reply.
It was upgraded to 1.4.1 automatically.
Do you know how to go back to 1.4.0?
And how to prevent it upgrading?
Thanks,
Kevin

Yes use this method to go back to stock, after that you probably want to use this to get 1.4.1 with root and android market (You must go back to stock to use this method is why i put it as second option) then use this method to block OTA, Indirect just released an update! as some users have reported that they are getting the upgrade with the 999 method. If you want to be even safer then freeze device manager but you will have issues with some B&N bloat apps i think, you can unfreeze anytime.

Hey All,
So I used z4root and got temp root... which is great, I get into TB and it confirms that root permissions have been granted.
When I try to restore an app, the device reboots (what seems like a soft reboot to me - since I don't even loose root privileges)
I want to restore a bunch of my apps and their settings... so this is kind of important for me....
I've read on archosfans some posts where people said that they were able to restore with TB after temp root, so am a bit confused.
does anyone have any idea?
Well...
I figured it out, if anyone is interested...
All I had to do was to get busybox through TB.
Click the "problems?" button, and choose to download busybox.
Once I did that - no more problems.
I had successfully (I thought) rooted my NT using Indirect's script but I got the 1.4.1 update anyways.
My plan now is step back to 1.4.0 using the SD card method.
Q1: Can I do this while rooted or do I need to unroot first?
Q2: Should I deregister the devise first?
Q3: Should I uninstall Homecatcher?
Q4: If have to unroot, NT is not allowing Nookunrooter.apk to install. Is there another way to unroot?
Sorry if the answers to these questions are already posted - being a noob, I'm having problems finding every on the forums.
Thanks in advance!
My questions are now OBE.
What I ended up doing is:
1. Deregisted the device
2. use the SD card method to return 1.4.0
3. used indirect's method to root
Worked like a charm! I did not have to unroot or remove Homechatcher. No issues with the n button or anything else.
Thanks Indirect!
Im getting the problem that a lot of people have gotten, that the android market is no longer working (try to start it; You must add an account to the device to continue. Do you want to add one now?), probably due to an auto update. I had rolled back to 1.4.1 to root (which i later learned was unecessary), so the device updated itself a few weeks after my root. I used albert's method on a 4gb microSD.
Do I need to reroot the device? my concern is, will I lose all my apps, and all the settings of those apps? what all is lost / how should I go about fixing this?
anyone else have or know how to fix this issue?
go back to 1.4.0 and use albert's root sdcard method.
Will this cause it to try to update to 1.4.2 again in the future? Or will this fix it because the root was meant for blocking updates on 1.4.0?
I'll lose all my apps correct?

It all depends which root method you use to root but what you can do is always once rooted apply the the block separately by using titanium backup (indirect's method) that way you won't get the update, so far that is the most reliable way.

My bad if this is a dumb question, but where can i find documentation on the indirect method? Instructions files etc.. Ready to try this one

In the development section.
How do i roll back to 1.4.0 with out any back updates and fastboot is not working with the adb fix?
My prime came with 9.4.2.15.
Viper's tool work great. Rooted.
Installed OTA Rootkeeper from the market.
Let the OTA 9.4.2.21 update run.
Restored root with great success.
So those who are still locked(with warranty) should know that 9.4.2.21 update and rootkeeper seem to work.
Now... I have to give this tablet back to my girlfriend and I'm worried about loosing root with a wipe. How should I go about wiping or switching the main user account? Or should superuser and root be immune to wipe? Could I just download rootkeeper again and restore?
thanks in advance... long time android tinker-er but new to rootkeeper and locked bootloaders.

I wish Rootkeeper would include the option of choosing where you put your backup..
Anyway, the wipe will eradicate any and all data on the Prime, including the SU backup that Rootkeeper creates. *Root stays intact, just not the backup.*
But, lucky for you, sparkym3 has graced us with a root app that you can keep ready to go in your ASUS WebStorage or DropBox or external mSD card, whatever you want.
But again, everything on the internal SD card will be lost when you wipe so be sure to back up your apps and their data (don't do system apps and data, restoring these usually just causes problems) to a location other than /sdcard along with any movies, music, and other personal files.
*EDIT:
Actually, no root methods currently work on .21, ASUS patched the exploit (badly I may add)
Factory reset should not touch root and you have root keeper so your good.

this is true as I had trouble trying to unroot on. 21 after using root keeper, as a factory data reset does not remove root

This is true. But it does remove the backup and all other files, so you need to be sure and back up as well as run Rootkeeper again after the wipe.
Why trying to unroot? You could try reverting to .15 either through an "emergency update" or with the .blob method, both of which are in my signature, then remove root and upgrade again to .21.
At this point however, you'll be at the mercy of time for the next root method; you won't be able to revert again I don't think since you won't have root.
I installed .21 and my root access was intact. I did not use OTA rootkeeper. Do I need to use it?

Sorry . I mixed up with HTC sensation upgrade. I used OTA rootkeeper to restore root.
If you have safestrap go into the app, select the uninstall feature and re try the install. No need to download anyones utility or no need to factory reset.
do you happen to know the download path of the ota? Due to safestrap mine failed.. hate to download it again..
Should be in setting/ about phone/ updates
yeah thats to download it again.. i was hoping it would just install it if the system saw the file there. oh well at 55% i can wait a little longer..
After the phone reboots, if the install takes really really slow then ur on the right path
What if I have installed BootStrap recovery????

Arrgh i swear i did.. While i was doing tb backups it slipped my mine i reckon.. really wish i could find the dl path for the update... hopefully third time will work!
Whether uninstalling the "Razr BootStrap" using "Managa Applications" is enough... Or I have to do some extra steps too????
Please help me... I don't care much about root, as the update usually unroots it and I can root again easily...
Bootstrap may be a dif problem. Like i said i used safestrap. I dunno what else you have done to urvphone. You might need the dev team to help you. I never used roms so i was stock i also never froze any bloatware.
Ummm. You're welcome....

I think i thanked you last night lol.
arrgh 3rd time failed no bloat removed just stock rooted.. temp unrooted safestrap uninstalled.. any ideas? guess i might need to restore back to stock..
Sounds like you have something breaking the install. I know ive done very little to my phone. Factory reset may be your option but i would get hold of a tech here b4 u do anything

You need to first uninstall the razr bootstrap app through "manage apps" (look under the all apps tab - clear data first while you're there).
Then, with root explorer or such, go to the /system/bin folder, mount r/w, and delete the following files:
hijack
logwrapper
Then, rename logwrapper.bin to simply logwrapper (just remove the .bin)...
Reboot, and it should be all cleaned out.
I would also recommend using voodoo ota rootkeeper to backup your root, then temporarily un-root (hide root) before doing the OTA install.
If you still get ota install errors, then you probably removed some system apps that are verified before installation... check /cache/recovery/last_log for errors.. then either replace those apk/odex files, or flash the fxz..

Thanks so much for the info. That logwrapper file was withholding me from updating.
I tried deleting and renaming the files with no success updating. I eventually just ended up doing a factory wipe and using Matt's Utility and flashing back to stock. It was a little frustrating, but the Verizon backup utility combined with Google services saved me. I guess i need to learn how to use Titanium backups. lol
this thread should be titled "How I got my Safestrapped RAZR to install ICS OTA successfully", as your issue was more to do with safestrap then specifically just being rooted.
