[Q] nachoroot for first time rooter

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.

[Q] How do I find out what version TF I have?

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.

Easy Guide to Unlock, Root, and Flash ROM?

Hey guys, I just unlocked and flashed ROM on my LG Optimus G phone and looking to do the same with the TFT300T.
I did read some of the stickies, and there are various ways of doing this.
Anyone recently unlock, root, and install ROM on your TF300T? Which directions did you take? I am looking for the simplest and user friendly solutions. Any tips are much appreciated.
Thanks

What rom/ android version are you currently running?

I am on 4.2.1

First off you need to go to Asus support site and download the v8 unlock apk & run it (unlocking your bootloader).
Then have a good read here to learn how to flash the compatible TWRP custom recovery (2.4.4.0), the root your device.
As of know I don't know about any custom roms that will boot with the newest bootloader. Correct me if I'm wrong here.
Do have a good read though, and read it again - and make sure you understand it and then read some again. Then proceed by following the steps to the letter.
Have fun! :good:

Can I just download an older unlock apk if the current ROMs don't run with the v8 unlock?

No. If you updated to 4.2.1 you need to use the v8 apk.

Got it. So if I am on 4.2.1, there's no ROM that I can flash? Just want to get that absolutely correct.

Not that I'm aware of at this point. The new bootloader uses a different partition layout than the "older" 4.1 ones, so it will soft brick (as will flashing the wrong recovery, you'll want the latest twrp 2.4.4.0)

Thanks. That's really good to know.

So at this point, for anyone on the OTA 4.2.1, we can unlock and root but cannot install any kernels or ROMs yet, correct? Anyone know if CleanROM is being updated to work for us yet?

I think you can try this ROM.

Thanks, I had a look at that. I'm having a hard time figuring out which set of "instructions" to use. The ones on the OP:
Code:
Installation instructions:
- Unlock your device using the Asus supplied APK. Search around the forum for the official unlocking app.
- Install a custom recovery such as TWRP. Follow the instructions in the TWRP thread (website)
- Copy over the ROM zip to your Internal Storage or your microsd card
- Boot into recovery and simply install the ROM. This ROM will NOT wipe your current ROM settings
- Enjoy!
Or at the bottom of post #3 (where it seems to have the download links) it says "BEFORE YOU DOWNLOAD AND INSTALL ANYTHING IN THE JB 4.2.1 folder BELOW CLICK THIS LINK FOR INSTRUCTIONS AND WARNINGS!"
Which then gives you this set of instructions:
Code:
The stock ROM is uploading in the JB 4.2.1 subfolder of the main download folder on the first page..
Be warned that once you do this... you will not be able to simply restore your backup and go back to 4.1.1. You will need to flash the JB bootloader ( think craig gomez has a package for it) and repartition your tablet. So be ready to STAY on 4.2.1
Instructions:
1. Make a full backup of your internal storage and copy it over to your computer after. Do a "nandroid" or "backup" in TWRP and copy the resulting folder/files to your computer (if you want a backup...)
2. Download and copy the Energy_JB_4.2.1_Partitions.zip to your tab.
3. Reboot into recovery and flash the above mentioned file. Reboot.
4. Wait while the blue line at the bottom is doing its thing. At the top you should see a "signature match" message. This WILL WIPE YOUR INTERNAL STORAGE. Which is why I recommend a backup!
5. At this point the tablet will NOT boot. You need to manually reboot and get back into recovery. Hold power and volume down and choose "RCK".
6. Either using an sdcard or adb, copy over the actual ROM zip Energy.TF201.JB.03.15.2013.STOCK.zip and flash it! Reboot... and... Enjoy.
Having started on the OTA 4.2.1, I can't figure out what I need to do here. Do I require the Partitions.zip, or am I already set with that having installed 4.2.1 prior? Conflicting sets of instructions are bad...

Sbdags is working on it and has made some great progress. He's got it figured out where we are gonna be able to flash the bootloader, kernel, and custom recovery all at one time. From what I've read, I have a feeling a release is coming pretty soon.
Just keep up with the thread and you'll be good to go.

Im posting because I want to keep up on this thread, I too have an ASUS TF300 with 4.2.1 and want to root it and install a custom ROM like I have on my Droid Razr.

I tried several ROMs and this was the only one I was able to get to work.

I have been having lag issues since the OTA upgrade to 4.2.1 and figured putting a custom ROM on the TF300T might help things out. Glad I came in here. I had unlocked it via the ASUS website: http://www.service.asus.com/#!downloads/c1wax

So what else can u do with unlock?

[Q] Root, Custom Roms, Unlock on Asus TF700T

Hello,
i was wondering if someone could answer some questions that i have about android and the asus tf700t.
now i already searched on google and on xda but there are so many informations and i just cant tell which one is the "best" or the right one.
My Asus is unlocked. i got that far and didnt think it would be too hard to root but i see command lines and/or 3 different kinds of software or files that i have to download first or programs like unlockroot etc.
so i was wondering if you could answer me a few questions.
1. do i need to root to put on a custom rom or is it enough that the device is unlocked?
2. what is the easiest and safest way to root?
3. what are 3 good custom roms?
i have android 4.1.1 on my asus and heard that 4.2 is out so i would like to update it but i never had an android device until now so i just want to make sure i m not destroying it after 3 months of use.
Thank you very much
Ben

Custom ROMS are pre rooted, usually, so you best bet would:
1. Update to stock 4.2.1
2. Root using Motochopper
3. Download GooManager(give root rights') from Play Store and Install TWRP by installing open script recovery.
4. Perform a factory reset via TWRP, without wiping Internal storage, or MicroSD card.
5. Install CromiX or CyanogenMod
There are other ROMS out there, but it is advised to install CromiX first because it is stock based and can be flashed over the stock ROM.
Also, make sure you know how to get into the recovery manually, and make sure you check files before flashing to make sure things downloaded properly.

Asus pulled the JB 4.2.1 firmware off their website, probably because they realized it had too many bugs. They probably are working on a new release and I would wait for it.
In the meantime read the forums and familiarize yourself with the process of rooting, installing a custom recovery and flashing custom roms.
If you don't want to wait, search for the forums on the Motochopper tool. I believe you can also use it to gain root under 4.1, but I'm not 100% sure.
If you have root, download Goo Manager, tap the 3 dots in the upper right and choose: Install open recovery script.
This will install the TWRP 2.5.0 custom recovery.
Boot into TWRP and select 'Backup'. This will give you a nandroid backup of your current system. Copy it to a safe place.
Next, you still being on 4.1, you need to flash the JB 4.2 bootloader which is version 10.6.1.14.4. You'll find a link in post 1 of the Cromi Xenogenesis thread in the development section. The dev packaged it with TWRP 2.5. It doesn't hurt to re-install TWRP.
Also download the latest release of the Cromi-X (ODEX) ROM, currently 4.4.1, and place both zips into the root of your internal or external SD card (your choice).
Boot into recovery, choose 'Install', navigate to the 10.6.1.14.4 bootloader/TWRP zip you downloaded and swipe to flash it. After installation the tablet will reboot into your old rom - this is fine.
At this point, just to be safe, you may want to check if you have the correct bootloader installed: Boot up with Vol Down and Power button and read the tiny script. It gives you the bootloader version.
If you're 100% sure you have the correct bootloader and TWRP 2.5.0, proceed:
Boot into TWRP recovery again, select Install, select the CROMIX 4.4.1 zip and flash it.
The Aroma installer will start and give you options to choose from. Stick with most of the default options for the beginning. You can always re-flash the rom with a different set of options selected.
Enjoy!

[Q] TWRP Causes System update and fails

I have searched through multiple threads regarding TWRP and upgrading to ChromiX 5 but haven't found anyone running into this issue. Disclaimer this is my first time unlocking/rooting a device.
I have an Asus TF700T that has been unlocked, because of the software version (10.6.1.14.10) rooting doesn't work via Motochopper. However, based on the thread I can still load a ROM without rooting b/c i unlocked. I have loaded GooManager and installed the recovery script, but when i try to reboot into recovery mode instead of TWRP opening I get the Android system update screen and then a dead droid with the red triangle and failure. I have the Chromi X-5 on a separate SD card so i don't think that is contributing to the failure. Am i missing a basic step that seems common sense? I'm lost here.

Follow up on this, i did find a related post http://forum.xda-developers.com/showthread.php?t=1797692&page=4 where it looks like TWRP isn't actually installing (guessing b/c 10.6.1.14.10 can't be rooted?). I've followed the directions installed GooManager and see the blob in my internal storage.

You need root to install TWRP with GooManager. That's why this method does not work for you.
Go to the OP of the CROMI-X thread, sbdags just revised the instructions and the steps are easy to follow.
http://forum.xda-developers.com/showthread.php?t=2425383
You can use Scott's tool to install TWRP (download link is in that thread) and then flash CROMi-X from TWRP.

That appears to have tried to install, but after the loading bar turns blue it almost seems like it doesn't finish. I have 2 probably really stupid and extremely nooby questions:
1. Should I have a root app or TWRP on it after doing this?
2. Should I be able to use GooManager after running this tool?
EDIT: Now i realize i was able to fastboot into TWRP after running that, sorry Noob level failure right here
