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.
We just got the Prime and I want to root it so Titanium Backup and MyBackup Pro will work with it fully. Question is what is the best method to root it with? I prefer to avoid the Asus Tool for unlocking as that will probably void the warranty. I don't want to have to worry about other ROMS or that just the capability to run apps that require root for this Tablet.
Here ya go.. The unlock tool is also built into this as an option so make sure you just do root.
Then get voodoo root keeper from market, and have it create a backup. That way you can easily gain root access back after the OTA updates.

Excellent thanks.. Just what I needed especially the tip about voodoo root keeper.
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.
I have read though all topics for Prime and found that there is no way at the moment to root ICS .21 without unlocking bootloader. I have an idea below Is it possible or not guru?
Anyone who has installed and done backup root by using OTARootkeeper, pls locate its backup data (.zip or xml or whatsoever) then send to users who already upgraded to .21 to restore it. It maybe restores a root.
If you are able to locate and have backup file for OTARootkeeper pls send it to me I will give it a try and report.

I think the same way I previously wrote on this subject.

Hi all,
Prime Transformer using Asus for a month. Detail the issues which the forum for a while and looked, I tried some of the root methods. Authorities, however, and 9.4.2.21 update lost. I am writing this message I can think of something to consult.
Pending the development of a new method, like helping a friend with OTA Root Keeper backups can tell us where can we solve this problem?
For example, you share with us to take backups of AppBackup Rootkeeper OTA with the application?
Best regards from Türkiye.

No, it's not possible. If you think about this for a moment, if this were possible, it would be a most trivial way of distributing a root exploit - and would already be common knowledge.
Without root, only certain well controlled files can be executed. It's not possible to add files to this set on any device which is not rooted unless there is an alternative way of accessing the internal file system (bootloader, flash from PC or recovery mode).
OTA rootkeeper relies on being able to _use_ a backup copy of the files needed to gain root priviledges - this file must already be present on the device in the right place. You should change the title of your thread to clarify that it's not useful...
With the coming update to .28 dont make the same mistake many of us did with .21. Use rootkeeper, takes a minute and saves a hassle. I've read that .28 fixed the workaround to downgrade so you really dont want to forget to use rootkeeper unless you want to go without root or unlock for a while.

Thanks, forgot that!
Just a general shoutout, dont say you werent warned!
(If you have experiences with the .28 update why not keep it in this thread? no use having a dozen threads about the same thing like we do most updates )

If you want to revert to stock and KEEP ROOT do the following (worked for me, ymmv)
Download the firmware you are CURRENTLY ON (for me its .21)
Put that firmware in the ROOT DIRECTORY of your prime (not the removable SD card)
Restart your prime, it should detect that there is an update available and update you to .21 (the same FW you are on)
NOW that you are stock (all stock apps are there) you can go about reverting back to .15 (or your favorite pre-.21 update), use wolf's guide:
http://forum.xda-developers.com/showthread.php?t=1622628
Get blob file for firmware (download firmware, extract, find blob file. I used .15) MAKE SURE ITS FOR YOUR AREA (Mine is WW)
copy blob file to root dir of the prime
In shell execute: ADB Reboot
let it reboot, dont touch anything
In shell execute: dd if=/sdcard/blob of=/dev/block/mmcblk0p4
it will appear nothing is happening for 3 to 10 minutes. Mine took closer to 15 minutes. BE PATIENT THIS BIT TAKES A WHILE
when you see records in/out in how many seconds you know its done.
in shell execute: ADB Reboot
you should now have a clean, freshly installed prime on .15 Root with your flavor of root tools, use OTA rootkeeper and OTA to .21, then when the OTA to .28 is ready in your area your good to go!
Credit to wolf, go to his thread, hit the thanks button.
Hit my thanks button if i helped! Good luck and i will try to bring forward important info as it happens.
Unless of course Asus do a **** move and completely overwrite /system or rm the voodoo rootkeeper backup specifically in the update script.
Thanks for the reminder.
Maybe Demandarin tells us how he lost his root. Clumbsyness or override by Asus?
Tell us the story bro.

If I had to guess it would be because he had to manually install the update from his micro-SD card. OTA Rootkeeper won't work that way.
Hi everyone
I rooted .15 and use OTA Rootkeeper and then OTA to .21.
When the .28 will be released do I have to do something with Rootkeeper or I just OTA to .28...then open Rootkeeper and recover root from .15?
Thx for answer and sorry for my english

ouch !!
Edit:
Let's see; I am on my forth prime since early april now. Three of them on .21 and I had to update all the three via an update.zip from the micro-sd. Do I remember this? Or is it wishful thinking??
... Yeah, I did it from the micro-sd card.... Pure speculation: otarootkeeper will work... Also Demandarin mentioned that GK asked him to do whatever test on his formerly rooted device, so this implies it should still work...but then GK probably doesn't even know how to power on the prime..........................................hell.................

You shouldn't have to do anything, but to be safe, open the app and ensure that it says something along the lines of "Root backed up/protected."

Your prime won't be screwed up, but you will be unable to load the update.
I speak from personal experience.
I have heard it looks at the 'preinstall' folder.
Where else I do not know? Help

I never made this mistake, so I can't speak from personal experience, but I thought I remember people having problems as a result of this. However, I very well may have just been thinking of being unable to load the latest update.
Regardless, you don't want to experience either of these issues

Which .apk's have to be "in place" for the update load? All of the Google and Asus ones?

I think the simple rule of thumb is that anything that cannot be uninstalled the normal way (e.g., through the settings menu without rooting and deleting/renaming .apks) must be present.
Where is the backup file made by Root Keeper saved?
Mine is rooted and su file is saved, but will the OTA delete the restore file when installing the new fw?
Should the Ota RK file be saved on the SD Card instead?

You will be fine unless you choose to factory data wipe.
I saved a copy on the SD, just in case.
Appreciate the reminder. Rootkeeper looks to be in order and I think all I changed was the build.prop mod and the gps mod. I just put them back to stock so hopefully I'll be okay. Now comes the wait.
For those who forget how to revert to stock i wrote up a quick guide and posted it to OP.
Basically:
Download current FW
Install current FW
Use Wolf's guide to revert
Root
Use OTA rootkeeper
OTA to current version.
Good luck!
If I disabled some apps in app info will that be OK when updating
Or do I have to enable them all again
