Hi!
I'm a happy user of the ATP since this summer. When I buy it, it comes with ICS (Android 4.0), and when Android 4.1 was released, I didn't wait to an official upgrade: I follow the instructions and unlocked with the official ASUS application and then installed CWM 5.8.2.0 and a CyanogenMod 10 nightly.
Now, I want to move forward, but I read some thing about different bootloaders and I prefer to be more careful than I usually am.
First, I don't if I can return to an official ASUS ROM with my actual configuration (unknown bootloader, CWM 5.8.2.0 andCM10 nightly).
Second, I don't know if there is an thread about the official ROMs (I was unable to find any).
Third, I don't know if the latest ASUS ROMs are Android 4.2.1, 4.2 or 4.1.
[cry mode]In addtion, trying to look my bootloader version I made a mess and wipe my user data, so this is the perfect momentum to move backward/forward and put my ATP in the "right way".[/cry]
Thanks in advance and best regards
Ok, I just have found a thread about the official updates and it looks like ASUS is still on 4.1 (not bad!).
So, One of my questions is answered
I hope that when you say "unlocked" you mean after getting nvflash access:

(will save you from bricking)
Generally, you have the ICS bootloader and the JB bootloader. Most roms now require the JB bootloader, so if you're looking to flash new roms, especially something like craigmcgomez's unofficial AOKP/CM roms (based on 4.2), you'll need the JB bootloader. I simply used this rom:
http://forum.xda-developers.com/showthread.php?t=1927494
This is the official worldwide ASUS update (there's also a US version in another thread, not sure if these are still the most up-to-date), but it's 4.1 (.2?), rooted and it comes with TWRP recovery (I prefer over CMW5), but most importantly, it comes with the new JB bootloader. I understand you won't be able to return to the ICS bootloader after you update to the JB bootloader, but I don't see a reason why you'll want to. Either way, you can flash this even if you're on the ICS bootloader (and if you're already on the JB bootloader).
After you flash this you can flash JB bootloader-compatible roms. I recommend AndroWook or AOKP. I'm on AndroWook, but I'm waiting for official CM10.1.
If I'm not mistaken, the CM10 nightlies work on the ICS bootloader, and 10.1 will officially support the JB bootloader only, so my guess is you're on the ICS bootloader. If you updated to stock 4.1.x or any rom that says it comes with the JB bootloader, then you know you've got the JB bootloader, otherwise you're probably on ICS bootloader.
Thanks WiW for your answer.
I don't know if I have unlocked the Nvflash...
I refer to using the Asus tool for being able to enter to the bootloader/recovery (when the message "This device is unlocked"appears on the top left corner when the Nvidia logo is on the screen.
I will check all your links now. A lot of thanks for you time!

Now reading your two first links I'm pretty sure that I didn't unlock my NVflash. I only unlocked my bootloader for being able to flash a recovery, just that.

Well, if you're not sure you can follow this guide and see if it works for you. If you did not follow the steps from the previous links I posted, I think there isn't much you can do about it...
Sorry for the misunderstanding. I was able and I successfully unlocked and backup my files with NVflash.
I installed the official Asus ROM and the JB bootloader and TWP Recovery.
After that I've installed the Androwook, as you suggested. It works fine, but I expected 4.2... my fault, I didn't read the entire AndroWook post.
A lot of thanks WiW

This on behalf of a coworker, who's developing an app for the TF201.
He accidentally did an OTA upgrade to JB. Unfortunately, the client's acceptance testing is only for ICS (please don't ask, and please don't say the app should be made to work with JB), and he needs to downgrade the Transformer back to ICS.
The device has not been unlocked and has not been rooted. It was stock ICS before the upgrade and is currently stock JB.
I don't have much experience with the Transformer, though I've mucked around with alternative ROMs for my B&N Nook Color and my Galaxy S.
Do we need to do the following?
1. Unlock the bootloader (using the V6 unlock tool from Asus, even though it's labeled as being for ICS)
2. Install ClockworkMod
3. Use CWM to install the ICS binary images that we get from Asus
On one of the threads discussing a JB to ICS downgrade, someone noted that there's no way to revert the JB bootloader to the ICS one. If that's the case, what are the implications of that?
Thanks.

Unless you did the nvflash process before going up to Jellybean (which you haven't because you are not even unlocked) then you cannot go back to ICS. Do not even attempt it you will brick the tablet.
I got the boot unlocker from ASUS and unlocked the Transformer Prime about 6 months ago (while on Android 4.0.3), with the help of a techie friend. Since then it has been lying in a corner. Given that my new work requires me to travel, I am planning to use Prime as full time laptop replacement.
Browsing thru the forums, I get the impression that Androwook (based on JB) is the most popular & stable ROM for TF201. I would like to flash my device with this ROM. However, I do not have experience of flashing a ROM. One of the prerequisites of Androwook is - Unlocked Transformer Prime with either CWM or TWRP recovery and updated to the official JB bootloader.
Can anybody help me understand how to go about flashing a new ROM in a step by step fashion without need a Windows PC or point me to a video with detailed instructions.
PS: I have a desktop running Ubuntu. So, I am hoping that flashing new ROM can be done without needing Windows.
Only experience I have with flashing ROMs using a *nix box was with my old WinMo phones. worst case, just run a VM and follow the instructions in said ROM's post.

How to get to JB bootloader on 4.0.3?
The link does not talk about the need for TWRP and how to install JB bootloader on a transformer prime with 4.0.3 Android. Any further pointers will help.

If you are unlocked on 4.0.3 ICS and want to upgrade to Jelly Bean the first thing you want is TWRP. You can install TWRP using one of the methods outlined here: http://www.teamw.in/project/twrp2/93 I imagine the terminal method will be your option since you don't have Windows. Since you're on ICS make sure you use the proper version of TWRP.
Once you have TWRP then all you need to do is find a rom that has the Jelly Bean boot loader included in it and flash that (such as Androwook V1.3).
Please let me start by saying that I feel like an incompetent idiot...
I have searched through the forums without find in a answer to my issue. I have not bee keep up with the tfp scene as I was pleased with how my prime has been running for months. I decided to move up to newer ROMs...thinking hairy bean
So I am rooted and unlocked....don't remember when I did the ladder. I just know when I boot, it says device unlocked I the upper left hand corner. I have twrp installed and am currently on Cm 10.1.
How do I know if I am ICS or jb boot loader?
How do I just upgrade to jb Boot loader to be able to install all these newer ROMs? Is there any easy way? I am hesitant to install a ROM which explicitly says I need to have jb boot loader if I am not sure what I have....
These may be stupid questions but given all the talks about bricking, etc....I am being cautious....thanks.
Leo
I guess my biggest issue is where to go from here....?
All the guides are for new users who are already on jb from factory or have upgraded via official Asus update....tough to find somthng for someone who is 3 months behind.

When you power on the prime look where the "Nvidia" logo is. If it is in the bottom center it is ICS bootloader if it is bottom right it is Jellybean bootloader.
In the second post of the hairybean thread there is instructions for upgrading from ICS bootloader. These wont do any harm if you are already on Jellybean bootloader so you could run them either way.
If you are still on ICS bootloader tho I would highly advise that you do the nvflash process first to make your prime unbrickable.
Hello all....I'm fixing my dad's tablet tf201 and I'm looking for the JB Bootloader so i may update it and put on a JB ROM...anyone know where I can update the firmware/bootloader? The tab is on IC BL..and unlocked...thank you...been searching around

Very important you don't mix bootloader/recoveries ICS/JB. That will likely brick your prime!
Assuming you are on stock ICS, safest way is to go straight to the Asus website and update full ROM to latest official JB firmware (10.4.2.18).
If you don't already have NVFlash backups, make these now (Best Guide) and then install latest TWRP recovery for JB and you will be good to go for custom ROM of your choice.
WARNING: Steer clear of CWM recovery as the TF201 version was never updated and if you install the one from their site on to a JB bootloader it will also for sure brick your device. (You are OK with the version of CWM left behind by Flatline as this has been customised for JB by the AndroidRoot team - but it is based on an old non-touch version so best to change to latest TWRP straight away).
Heya there and thanks for looking!
I know that this might be a "Why does this thread even exist?" looking question here but I just want to go on the safe side before making any changes (like flashing with nvflash) on a "might unsupported" setup I have right now on my TF201.
Also it's good for myself too to learn a few things more before trying and maybe bucking the whole thing up
Okay, so let's start with the configuration on my TF201 first so you guys know what you're dealing with here:
ROM: Hairy Bean (AndroWook) 2.2
Bootloader: Unlocked
Bootloader Version: 10.6.1.8-20130225 (4.2.1)
Additional Infos: Device was OTA updated to JellyBean and not rooted/unlocked before using any nvflash or backup method.
If you need more infos I'll add them once you tell me that I forgot them, thanks!
Now the question:
I found the latest entry from AndroidRoot.mobi saying that nvflash will finally work with JellyBean updated devices too (as far as I read tho). (Link to Post)
Besides the Bootloader version it says that it's incompatible with Hairy Bean (aka the ROM I'm using right now).
Next step I would do is downgrading to the 4.1.1 bootloader with the flash-able ZIP AndroWook provides in their thread and flash another ROM (which all require to be on the 4.1.1 bootloader). (Link to Thread)
Now my worries are if this will work or not because I made the OTA update before and I heard/read from many that it's not easy to downgrade to a previous bootloader version.
I don't want to brick it in any way, that's why I better ask before do anything
Will nvflash work at all? Or did I just get something wrong here with reading all about that stuff on AndroidRoot.mobi? Because as mentioned above I heard some saying that it doesn't work at all on the JB bootloader.
Thanks much already for answering!
