I've heard that there are different versions of the TF and one in particular can't be rooted or something. I plan on rooting this weekend but I want to make sure I have a rootable version. How can I check?
With all the methods out there, It's hard to believe you'll have an unrootable tablet.
This only use to be true before RazorClaw, NachoRoot and ViperMod was avaiable.
Back then you'll have to figure out if you have an SBK v1 or SBK v2 to use NVFlash.

Many thanks for the information!
My TF has an SBK v2 because the serial number starts with BB0. My TF was upgraded to stock ICS downloaded from the Asus website (US build version US_epad-9.xx....). My questions:
1) Could you recommend a rooting approach about my situation? How can I check whether the TF is rooted or not?
2) If I flash the full version of ICS using Plan B of ICS - CWM flashable here (http://forum.xda-developers.com/showthread.php?t=1514658), my TF will be rooted, correct?
3) To be able to flash using Plan B, is the following the appropriate CWM I need to install first (note: my TF is not rooted yet)?
http://forum.xda-developers.com/show....php?t=1093818
Sorry for these basic questions. I've never done any tablet flashing before. Really appreciate any guide and pointers.

You have to be rooted first. Being rooted allows you to install CWM. CWM enables you to flash ROMs.
(NvFlash lets you flash roms without rooting and without CWM, but it doesn't work with sbk2 so you can forget about it.)
1) You root with this http://forum.xda-developers.com/showthread.php?t=1516639 Make sure you read the post completely. The option you need to use for TF101 ICS is OPTION 1.
2) Supposedly the root kit also flashes CWM to your TF at the same time but people are reporting it doesn't work. In that case, use http://forum.xda-developers.com/showthread.php?t=1346180 confirmed to work on TF101 ICS rooted with vipermod.
3) Now you have rooted ICS with CWM. Read up on CWM and how to flash ROMs if you want to.

I believe this is my first post on these forums. I just did the nachoroot mod today per
[ROOT] NachoRoot - supporting all firmware jan 3rd 2-118
and
[Update: Works On The OG Transformer, Too!] Exclusive: 'NachoRoot' Brings Root Access To The Transformer Prime, Even With The Newest Firmware:
on my TF101 B80 32 gb.
I did the procedure per the second link above. I've been able to verify root with Root Check Basic from the Android Market.
I've never rooted an Android device before and am quite concerned about unrooting, in case I ever need to return my unit to Asus.
I've heard I need cwm, the clockwork recovery mod, in order to unroot. I hope it is ok to do this after the initial rooting procedure.
Please pardon me if this has been asked before, as it my first time, and I find a lot of the documentation a bit cryptic.
Thanks in advance...
Yes the procedure to unroot with your build number required flashing a repacked stock ROM via CWM recovery. For TF with older SBK they can use NVFlash.
You can flash CWM anytime with RecoveryInstaller

Thanks fire the response!
I've managed to browse parts of the file system previously blocked. Otherwise, I haven't made another changes to my system. Its nice to finally where some of my apps have been storing data.
I am curious about cwm which I've installed. It enables recovery mode to restore the stock ROM. It is one of the two options presented after holding the power and volume down buttons together. One option is cold boot and the other is recovery. The recovery option was there before nachoroot and the cwm installations. What is different about the recovery option now versus before?

Are you sure you have flashed CWM recovery? You should have a lot more options.
After installing RecoveryInstaller, did you open the app and click on "flash CWM recovery" tab?
I didn't click on the flash tab because I don't intend do recovery at this time. To be clear I understand what recovery is, I think it means to return my TF101 back to an unrooted state with the current ota release, which is .23, and also wipe out all my data. If this is incorrect, please let me know.
You said I should see more options than just the flash tab. What else should I see? And when should I see it?
Now that I've successfully rooted, my main objective is to learn how to return my device back to its unrooted state in order be ready for the ICS ota update when it arrives. If that means I'll also wipe out my data in the process, then I'll need to learn how to backup and restore.
Please do let me know if I understand the process or not. I still have have a reading and learning ahead.
Recovery lets you flash packages, ROM patches, and complete ROMs that require very deep (i.e. low level) system access.
If you don't intend to flash any custom ROMs (e.g. Revolver) or install things that need low level system access (e.g. a USB to Ethernet adapter) you won't need to flash CWM.
One of the admins on Transformer Forums gave me the impression I need cwm to unroot my TF101. That is the only reason I downloaded it.
If I don't need cwm to unroot, then I'll focus my reading on unrooting link listed earlier in this thread.
I don't have any interest in other roms, at least not for now. My concern, for now, is unrooting when it comes time for the ICS update...

The second link above (theunlockr.com) refers to old firmware (repacked-8.2.3.13_US_without_SU_app.zip).
Is that file already outdated?
Perhaps a newer version for .21?
Well it all depends on your serial number. Early builds (B60 and earlier plus some B70) you can use NVFlash to get back to totally stock.
If you have B80(and some B70) and above you'll need cwm recovery to get back to stock following the link i posted above.
I finally watched the video from your earlier post and it answered a quite a few questions.
Bottom line: when it comes time to update to ICS, do I need to unroot first?
The ICS update is my main reason for unrooting. I read for some users lost root after the last ota update to .21. I don't have any immediate need to unroot other than to prepare for the ICS update when yet comes.
And there's also a long term need unroot when and if I ever send the unit back to Asus for service.
So, my brand new Transformer came yesterday (From Amazon) and it has an SBK v2 bootloader (sbk detect under mac, serial is BC0KAS), here is what I understood, and ask for questions, after many reading, can you please confirm or correct?
1- SBK v1 can be rooted, put custom roms, return back to stock, unbrick in case something goes wrong with nvflash. [CONFIRMED]
2- SBK v2 can be rooted? (some say B70 can, or is it just B70 with SBK v1?) [CONFIRMED]
3- SBK v2 can have custom roms? (depends on point 2)? [CONFIRMED]
4- SBK v2 cannot have ClockWorkMod? [Wrong, SBKv2 CAN have ClockWorkMod]
5- SBK v2 does NOT support nvflash, so if you softbrick you cannot recover (I am certain of this one, I guess). [CONFIRMED, if you damage ROM & clockworkmod = BRICK]
What can be done then with an SBK v2 device? wait for developers to find the ways to crack it (as sbkv1), or have an nvflash working?
Is there some petition open to tell Asus to unblock the bootloader as they did with the Transformer Prime?
currently (after 1 day), I am already thinking of returning it back.
I know i might be asking a lot of questions, but information is not easily available in 1 thread.
Update:
New question: with SBKv2 is it possible to return back to stock (Stock ROM, unrooted with stock recovery)?
Thanks in advance...
SBK doesn't keep you from rooting from what I understand, the firmware version does (current 8.6.5.21 has been cracked and can be rooted by nachoroot, or if not can be firmware upgraded to 8.6.6.19 and rooted with razorclaw)
SBK2 simply keeps you from using NVFlash to recover, as far as I know, once you are rooted, you can install CWM recovery on any SBK version.
Just alot of SBK2 owners have not rooted or installed CWM if they did root for fear of losing their recovery (if you bungle the recovery, you may be able to flash your recovery through the ROM, if you mess up your ROM, you can flash another ROM through CWM or stock recovery, BUT if your recovery img is corrupted AND your ROM stops working, SBK1 can flash both via NVFlash, SBK2 is effectively bricked)
EDIT: SBK2 USED to keep you from being able to root when NVFlash was the only method available for rooting and installing superuser and busybox, see here
http://forum.xda-developers.com/archive/index.php/t-1347388.html
I was going to say I will try to NVFlash my device and tell you if it is SBK1 or 2, I assumed it would be SBK2 because it is B70, but lo and behold it was SBK1..I would have been lucky a few months ago before the razorclaw app was developed and SBK2 was rooted, but I didn't get my TF until after that..
So, SBK1 here have gone to stock many times, but cannot confirm the procedure for SBK2 tablets, though I assume it is possible. Thought for sure I was going to be able to come back and say my TF was SBK2 and had been to stock, but nope haha
EDIT: considering you can backup your entire setup via CWM, recovery mage and all, and flash it wthin CWM (like restoring the backup) is evidence to me that you can no doubt unroot an SBK2 as long as you have a working recovery image.
From what I understand, the first thing to do on a new device is to have root (with the tools you mentioned), once you have this (stock ROM with root), you can install CWM, and with CWM you can install custom and stock roms.
but how can I bring back the standard Stock recovery? when I have stock unrooted ROM I can't flash Recovery partition from the Android itself, and nvflash doesn't work on SBK2. can CWM be used to flash a stock recovery over itself?
Is there any chance that Asus will unlock the TF101 when it releases the tool to unlock the Transformer Prime (in February, as promissed)? in case they both use same blocking technology?

Yes you can flash stock recovery over cwm from within cwm, you have to have the file..i found it and have it on my hard drive, but can't remember where i got it from..the same procedure as going stock on sbk1 tablets
The proof that you can flash recovery while in recovery mode is that you can install higher versions or different developer's versions of recoveries from cwm. Im sure when running cwm it is being read from ram so flashing the recovery partition will only affect your recovery after you reboot (i.e. Can technically go into cwm, flash recovery partition first and then flash stock rom, but i believe packages are available to flash both at once, and there would be no reason to do it in this order, but im pretty sure it could be done)
Somewhere on here is a guide how to return to stock to prepare for the ics update, it should contain the odd bits and links to fill in my sparse knowledge.
Getting back to stock ROM and recovery
http://theunlockr.com/2011/11/28/how-to-unroot-and-remove-cwm-recovery-on-asus-transformer/
That's the one!
8329 recovery.zip.. Btw it should be noted that the recovery image is not region-branded, that should mean it will work with any region, while you will need to make sure to get the region-specific firmware..
And i did the procedure in reverse from that thread, not to confuse, but i:
Placed both files (recovery and firmware) into my sd card root
Booted into cwm and flashed stock recovery, wipe everything before powering down
Rebooted into recovery again and flashed the firmware with stock recovery.
I think it will work either way, i left my rooted rom in place so i could install cwm if the recovery flash failed, i suppose the alternative is leaving your recovery in place in case the stock rom flash fails..i just like knowing on the first reboot whether my first flash was successful and not flashing blind imo.

That thread is full of bad information and garbage. I would forget it exists.
I was under the impression from reading different Asus statements that the sbk for TF-101 was going to be released with ICS the way it was with TF-201, did Asus not keep their word on this?

That would be news to me. If you could find a source for this statement, I would be interested.
From what I understood reading (this forum and other sites), the story is different between TF101 and TF201: the Prime has the bootloader locked/encrypted, and with it locked you can't even install the CWM recovery, while with sbkv2 you can do everything except nvflash, so i doubt that asus will release anything for the sbkv2 transformers.
anyway, i am not following the subject, but does the new Prime unlocker allow something like nvflash to work?

Anyway, yes 'Wheelie!' Nvflash for Sbkv2 devices has been released, and works very well on my b70 Sbkv2
it only works on the tf101 though, not the G or Slider.
I'm about to buy used Eee Pad Transformer TF101, with dock/keyboard. It has serial number starting with B90KAS and latest firmware update (ICS).
What is the current status of bootloader unlocking craft? Would I be able to install Ubuntu/OpenSUSE and/or use custom kernels with latest KatKiss ROMs?
I have rooted ICS, so pretty much stock. I haven't uninstalled or froze any apps, its just rooted. I have never installed CWM or any recovery on this but I would like to. Can anyone point me in the direction? By the way I have a B7O device and I'm not sure if its SBKv1 or 2 because I haven't gotten NVFlash to run yet. Up until now I haven't cared to have a custom recovery because I didn't plan on flashing anything due to the lack of unbricking support for the SBKv2 devices and I'm not sure what mine is, but I know most B7O's are SBk 2. I need to flash the current update.
RecoveryInstaller
http://forum.xda-developers.com/showthread.php?t=1346180
ok so ive searched everywhere and tried reading everything but im very confused. i see that it is going to be very hard to root my tf101 since i have the latest asus ota update (build #9.2.1.24) but i cant quite wrap my head around how to do it.
i tried using the backup exploit and sparkyroot but those dont work on the latest ota. i already have Rom Manager installed and tried the recoveryinstaller.apk from Gnufabio but those didnt do anything either.
iv read the thread about downgrading (Wolf's guide) but im hesitant to do that since i dont understand it and i have no experience using the shell command (is that the same as using a terminal emulator?) can anyone please explain the terminology and how to downgrade? what program do i need on my computer (running windows vista)? please be gentle and dumb it down for me and include any links to programs or files i may need
thanks so much
p.s. is a "Blob" the same thing as an SBF? and if i did a factory data wipe, would that downgrade from ics 9.2.1.24 or keep it the same?
Adb shell is the same as running a terminal emulator, just google android sdk download and click the first link. Follow wolf's instructions carefully using your favorite recoveryblob from the development and you should be perfectly fine. Never use Rom manager, please just uninstall it now. If you factory reset, the recovery will still be there, as a reset only deletes user data, to return to stock you would need to flash stock recovery over cwm (not recommended) or flash a whole ASUS ota package from their website (better, removes any root and rom you have, cross that bridge when you get to it) What are the first 4 digits of your serial number? (for ex: mine are B70K) If they start with B60 or lower (B50,B40,etc..) you can just use NvFlash instead of having to use wolf's guide to root. Don't be too scared, it isn't that bad, just follow instructions carefully.
Thanks for the reply. My serial is b60. After more searching I was able to find an adb dummies guide and was able to downgrade to .17 but I didn't read one extra post to see that sparkyroot doesn't work with .17
So I had to do it all over again and go down to .11 and that worked and then I used sparkyroot and voodoo ota rootkeeper. Will rootkeeper work/stay if I do a factory reset? Cuz some apps and services aren't working. Or should I just do the ota to .17 and then .24? And now I can use nvflash in order to flash a new rom? Is that in the market or just google it?
Thanks again
You didn't need to go through all that since you have NvFlash, but good learning process I suppose
At this point, since you're rooted, use recoveryinstaller again to install CWM recovery, download a kernel.zip (I recommend Guevor's kernel) your favorite ROM .zip, and a new recovery.zip (as 3.2.0.1 works but is pretty outdated) [OR you can go to team rouge's thread in dev for an NvFlash version of recovery and NvFlash instead of recovery installer and update, then apply rom and kernel .zips in new recovery]
Make sure to place the .zips on external SD card if you're using 3.2.0.1. Any other Qs?

NvFlash: http://forum.xda-developers.com/showthread.php?t=1123429&highlight=nvflash
Rouge Recovery: http://forum.xda-developers.com/showthread.php?t=1446019
when you say that recovery.zip 3.2.0.1 is outdated do you mean the CWM version?
is flashing a new kernel safe? this is obviously my first time with a tablet with so much "freedom" compared to my droid2global lol
personal opinion, what do you think of android revolution rom? any other recommendations?
Yes the CWM version, I did use 3.2.0.1 for awhile though, it works, it's just old.
Yes, flash away, just always remember to wipe cache and dalvik-cache before flashing anything.
Android revolution is a great stock based rom, if you like the tab the way ASUS sends it too you, I personally prefer AOSP based roms, so my other recommendation if you want to go that route is Megatron or AOKP Build 37
Guevor's v20 kernel is the best out atm, imo.
Hello,
I am getting a tf700 at the end of the month. I've been reading a lot of different posts about rooting, unlocking, updating to JB, etc...
What I want is to make sure I have the sequence of events correct so I can avoid any unnecessary headaches...
At the end of day 1 with my tablet I would like to have a Rooted + Unlocked device running the official Jelly Bean release AND have a full backup created using the NVflash tool found here.
Please let me know if I have the correct sequence:
1: Unlock device using the official ASUS tool
2: Create backup using the NVflash tool
3: Root device using DebugFS
4: Install SuperSU + TWRP recovery (using goomanager) + Rootkeeper
5: flash official JB update found on asus site.
Have I got it?
Thanks in advance!
i dont think you have to install supersu. If you plan to install cleanrom, it will already be there.
also, once you get your device and boot it up, jelly Bean should start to install on its own.
After the installation, then follow the steps you listed. But instead of installing the JB rom from the asus site, you can go to the development section for the tf700 and grab a rom from there.
put the rom on a microsd card formatted at fat32. reboot into recovery (hold power button and volume down until you get to the recovery screen. Choose recover (by pressing volume up) and go to your microsd and find the zip file to install.

Well be careful and If you intend to use NvFlash STAY AWAY from the 9.4.5.30 UPDATE or anything higher.

Thank you for your reply.
I didn't realize that I wouldn't have a choice about the OTA JB update on my new device. If my tablet automatically updates to JB, I'll have to use a different method for rooting (debugfs only works with ICS). That's no problem, but in order to create a backup with the NVFlash tool, I need firmware that is PRE 9.4.5.30.
So, I may not be able to create a NVFlash backup....
Is this correct?
