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.

I just rooted my TF101 using ViperMod but now I'm not sure whether I should install CWM recovery or not if I want to install further OTAs. I have read some threads but couldn't come up with a clear answer. I read somewhere that only stock recovery can receive OTA updates but also read that CWM can receive them too. If I can't install CWM then what ROMs can I install with stock recovery? What's the best way to go if I want to be ready for the ICS? Thanks!!

Technically you'll still receive the OTA update you just can't apply it if you have CWM or a custom ROM installed.
You can't install custom ROM without CWM (if you have an older SBK tablet you can use NVFlash with a compatible ROM).
So I shouldn't install cwm until the ICS drops right?

If you want to update to ICS via OTA don't instal CWM.
As you have been told, you will get the OTA message but the update will fail.
So you have two choices (or three):
* Keep stock recovery and update to ICS when the OTA update is available
* Install CWM and update to ICS as soon as a DEV publishes an ICS ROM
* Install CWM and remove it as soon as you know the OTA is due (pretty lame, but you could do it).
Regards.

I have a question about removing CWR. Actually 2.
1. Can't we just uninstall and wipe data with Titanium since it was installed as an .apk- from Gnufabio? (pretty sure this won't work but thought I would throw it out there anyways). Where is the recovery located on a tablet (what folders) Same as in phones?
2. Can we just flash the stock recovery by itself and not reset back to .13 or younger? If I am running stock ROM, it seems that I should be able to just reflash the stock recovery and replace it w/o changing the ROM or factory reset.
I have no problem doing it the long way but if it doesn't need to be done and we can replace the CWR with stock and not tamper with the ROM, it seems logical.
Clearly I just got the tab recently and have been reading and reading but they seem so much different than the way phones work. I am very comfortable flashing ROMs/Kernels/Mods on phones, but just a little intimidated with the tablet (for now).

1- The RecoveryInstaller app only help to flash the recovery image so no you can just delete it.
2- You can flash a stock recovery image via CWM. You can get a repacked version here.

I figured that would be the case with the executable part of the apk.
I read that thread but wasn't sure if only the stock recovery by itself could be flashed w/o the prepacked ROM.
Hi there!
I'm a owner of a TF101 (B50) for month now, and recently I had the need to switch between multiple version of Android (as I'm an Android dev) : back and forth to/from Honeycomb from/to ICS for example, multiple time a day!
So, as I'm used to do with all my "Google's Experience" devices (Nexus S, Galaxy Nexus), I installed CWM on my TF101 to be able to generate nandroid. So far, so good.
I then downgraded my tablet to stock 3.2 using nvflash, installed CWM, and did a nandroid. Great, I now have an Honeycomb backup. Of course, at this point, I'm no more able to upgrade using OTA, so here's my first question :
1- Once CWM installed, how do you upgrade to the latest build ? Asus blobs are not compatible with CWM!
Then, since I needed an ICS nandroid, I reverted to stock 3.2 (using NVFLASH), and I let the OTA did the job for me - before installing CWM. Ok, now, I have both Honeycomb and ICS as backup : let's test that.
I rebooted in recovery, and then restored my 3.2 nandroid (from ICS, remember?). All I had once the job was done, was the android logo with an exclamation mark
After some Googling, I understood why : unlike my Google's devices, on the TF101, it seems CWM can't restore the boot partition. So, the bootloader used was the one for ICS, and the tablet failed to boot.... Here's my 2nd question :
2- Am I right? What guys are you suggesting to be able to switch easily between different nandroid versions ? Should I nvflash the boot partition by hand? If so, where to find a documentation on NVFLASH ? (I'm regretting fastboot )
Thanks for reading.
You can repackage the blobs so that they can be flashed from cwm. I think one roach's 3201 recovery is packaged this way, so you can take it apart to see how it all works. Essentially blobs are flashed through the staging partition. There is a blob tools thread in the dev section that has all the details.
If you want to go back and forth between roms, I think that nvflash will be your best bet. Rayman and bubble bee have the most info. Check out therenwebsite. It's something like androidroot.mobi? There is also a full backup and restore thread in the dev section that explains a lot of the details of nvflash.

I read, somewhere, that we can flash stock Asus firmwares using CWM ('update zip') by first extracting the initial zip (which contains another zip containing the blob). Is it true?

yes but you will loose root and cwm recovery. It's the easy unroot method.
Not a big concern. I can easily recover both root and CWM using the universal root method since I have a B50!
Thanks
Will you lose root/cwm even if you have OTA Rootkeeper installed?
You Shouldn't but no guarentees x)
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.
I found this thread and since i am a newbie when i read it a few questions came on my mind
Alternative Firmware update Method
1. Decompress downloaded .zip file (it will be another .zip)
2. Rename it to EP201_768_SDUPDATE.zip
3. Format FAT32 the MicroSD card that you will be using for the update process
4. Copy the file to (the root directory of) your MicroSD
5. Insert it into the tablet
6. Shutdown (power off) the tablet
7. Power it on by pressing and holding VOLUME DOWN and POWER buttons simultaneously
8. When you see white text in the top left corner of the screen, release the buttons ^^ and press VOLUME UP button until you see Android logo and process bar
9. Wait patiently for 10 minutes or so
10. Enjoy!
Also remember that you will probably need to use RootKeeper to regain root privileges and reinstall BusyBox too (firmware update changes the /system partition).
That's the thread i have read and the questions that came to my mind are:
1.Do i use the same method for any update?
2.Is it a safe way to update my firmware because after you unlock bootloader no OTA update but only manual update is possible.So is this the right way to manually update any version of firmware update from now on?
3.Is there any other way to manually update my Asus?
4.Do i have to follow another way of installing the update because of the custom recovery that i have installed? (TWRP)
5.If i format the SD Card using exFAT will this method work or not?
I appreciate any help you could give me since i am a noob and some things seem really scary to me due to the fear of bricking my device,
Thank you in advance for your patience reading my questions:angel:
Help with OTA
Dino,
I have a few quesitons for you (just to verify).
Is your boot loader unlocked?
If so, are you running a custom recovery?
If not, then why don't you just use the over the air update?
If your boot loader is unlocked, and you are running a custom recovery (which I understand you are), then yes, you will likely need to update from SD Card from here on out. Once you unlock the boot loader you can no longer get OTA updates. I would recommend following this thread: http://forum.xda-developers.com/showthread.php?t=1915079
If you are already rooted then you can use SuperSU, and OTA Rootkeeper to regain root after the update. There are tons of threads that discuss this. If you are doing root for the first time, you should read this: http://forum.xda-developers.com/showthread.php?t=1916762
The SD Card format needs to be FAT32. In regards to being a "noob" and scared, you should be. Did you make a recovery image using NvFlash before you touched your tablet in the first place? If not, then I would recommend that once you get to JB that you never attempt to load anything on your tablet ever again, at least not until you are no longer a "noob", and you are understanding and accepting of the fact that you may hard brick your tablet some day.

Thank you very much for your kind reply.I am rooted but still have not unlocked Bootloader. After i've read several threads i was too scared to unlock my bootloader,that's why i was waiting for some answers in order to do it. Basically the only reason for me to unlock the bootloader is the fact that i can keep a backup of my whole device (nandroid if i say it correctly) by using a custom recovery, that's it and that is for me the only reason to do it. I am not interested in flashing custom ROMs just Backup my device.
So what is your suggestion for me to do, with the fact in mind that i want to backup my device.
As for the other thing that you mentioned "nVFlash" i don't know how to do it and although i have read some threads about it i am still very confused how to do it. If you could guide me through it, in simple steps, i would be very grateful. I am on .26 version if that helps.
So to sum up,I got my Asus rooted, locked bootloader, firmware version .26, stock recovery, help is always appreciated !!!
Thank you again in advance,

If you really just want to backup all your apps and your data, you do not need to unlock or install a custom recovery at all. Just use something like Titanium Backup and that's it. Everything else (kernel, system and recovery) can be restored from the official Asus firmware image.

That's exactly the same as I have (locked, rooted, .26), and I am still not sure whether I want to unlock my bootloader and void my warranty. I am at least interested in trying some custom ROMs later, but first I need to understand what exactly the locked bootloader prevents me to do (flashing and loading custom recovery/kernel images and using fastboot - anything else?).

You pretty much say it all, with unlocked bootloader, you could flash, custom recovery, kernel, rom, using fastboot, scripts excepted for boot animation for now, cause you need a kernel that supporting it, once we have a custom kernel that support boot animation, you could do that too.
Back to the OP topic, if you have locked bootloader, rooted and running .26 build, you have 2 options to upgrade, but first make sure you read the thread about how to make a backup of your bootloader using NVFLASH before upgrade to .30 or JB. This is extremely important and since you're still at .26, consider yourself a lucky one. Next make sure you have Voodoo OTA installed and make a backup of your root. Also verify that indeed you do have root by download "root checker" from the market. Also use Titinum backup and backup your device. Finally, you have 2 easy options to upgrade.
A. OTA,(incremental upgrade), automatic download and upgrade your device push out by Asus.(No brainer)
B. Manual upgrade, if you prefer to do a full version (fresh install). It is recommended that you do a factory reset before and after the upgrade.
1) Download the correct latest firmware from Asus site, for JB the firmware called US_epad_user_10_4_4_16_UpdateLauncher.zip (this is US version).
2) Extract the .zip file, it will be another .zip file. This zip named EP201_768_SDUPDATE.zip.
3) Copy the file EP201_768_SDUPDATE.zip from your PC to the root of your MicroSD card.
4) Insert the MicroSD card in your tablet and use this button combination to go to recovery --> Start the tablet by pressing Volume Down and POWER together for 5 seconds ,a message will inform you that you have 5 seconds to enter the recovery,press Volume UP before the 5 seconds expire. At this point the device will go in recovery and should start updating your firmware.
5. If you upgrade from .30 to JB, you could skip step 4 and after step 3, just reboot your device and it should find and prompt you to update.
Thats it ..profit!!
There are couple more, but mainly used if you soft brick or issue, like extract the blog file from Asus download and use fastboot to push etc..but I don't think we need that right now.
I'd like to know more about the details of using fastboot and the blob file. Can you link me to a thread that shows that?

I found that using fastboot from your pc is working bit better.
Actually, quite funny as I was just reading that. I'm attempting to downgrade to 9.4.5.30 now so I can root and then Keep Root and then re-upgrade and see if I can repair root.
I suppose this would be a bad time to think about 'blobbing' the tablet to JB
I would be more worried about the process except for the fact that I checked the binary-script file and all it does it put the blob on the device. No stupid patching like in Motorola devices. Makes like easier to deal with (in terms of applying updates) but a heck of a lot more bandwidth used (in terms of OTAs).
Speaking of which, are the OTAs the same files, full on blob installs, or are they patches? Just curious....

The OTAs contain patches for files in /system, and a blob for kernel, bootloader, recovery (EBT, SOS, LNX).
Background:
I got myself a second-hand I9020T a couple of days back which had CWM recovery and a 4.0.4 Userdebug testkeys build on it. As circumstances turned out, I flashed the phone to the factory 4.1.2 (from https://developers.google.com/android/nexus/images), but didn't note down the details of the old 4.0.4 ROM.
I rather like stock roms. However, I like stock roms with root even more.
Questions:
I wanted to know if there was any method to root my Nexus S without resorting to using ClockworkMod recovery? I'm hoping for a z4root kind of method which doesn't mess around with the boot loader.
Does such a method even exist.
I'm hoping that I don't have to mess around with the boot loader, yet get root access and all the power to do direct querying of my SMS DB.
Note: I can install CWM recovery, but I'd rather not. It's just the superficial choice I'm making, not a well informed decision.

As circumstances turned out, I flashed the phone to the factory 4.1.2 (from https://developers.google.com/android/nexus/images), but didn't note down the details of the old 4.0.4 ROM.
I rather like stock roms. However, I like stock roms with root even more.
Questions:
I wanted to know if there was any method to root my Nexus S without resorting to using ClockworkMod recovery? I'm hoping for a z4root kind of method which doesn't mess around with the boot loader.
Does such a method even exist.
I'm hoping that I don't have to mess around with the boot loader, yet get root access and all the power to do direct querying of my SMS DB.
Note: I can install CWM recovery, but I'd rather not. It's just the superficial choice I'm making, not a well informed decision.

You don't have to mess with the bootloader itself, just the recovery.
And no, you will need a custom recovery to flash chainsDD superuser or chainfire SuperSU. There's TWRP also available and popular, if you simply do not like CWM.

Is is possible to install the SU update (whichever of the 2) and go back to the stock recovery?

Yes. I don't see why would one want to do that, but that's possible.
Once you're done with your flashing, you can flash stock Jellybean recovery from here:
