thanks rayman! but i could not recover my recovery now. I'm stuck and don't know what possible things i can do.

i downloaded fews recovery img and push via NVflash but no luck. Now i can't boot into fastboot, just can boot into apx mode and system only.
[Asus  Eee Pad Transformer Prime] JoeyDelp:
Back to TF201

So for anyone wondering how to transform your TF201 back from HairyBean 1.2 with the TF300 bootloader and all, i did it and will explain briefly how i did so.

Firstly, I am not responsible for what happens to your "TF300" in this process. I did this purely to get back to TF201 and am just sharing my experience with you.

Need NVFLASH with your blob.bin that you created way back before S**t hit the fan.

Need asus stock .28 from sparky found here http://xdaforums.com/showthread.php?t=1708613

Need the recovery.blob for cwm touch 5.*.*.* (i forgot version, it's the newest one)

Stock android .28 found on Asus support site.

Blobunpack.exe, see the attached file

Open the sparky's unlocked stock rom and extract the blob and also extract the blob from the official asus .28

Run each of these blobs over the blobunpack.exe and store the blob.* files that pop out for each in 2 folders respectively.

Next boot your device in nvflash

Run the following commands in this specific order:

1. wheelie --blob blob.bin

2. nvflash -r --download 4 blob.EBT (came from Asus official .28 blob so redirect to the folder where you stored it)

3. nvflash -r --download 5 blob.SOS (came from Asus official .28 blob so redirect to the folder where you stored it)

4. nvflash -r --download 6 blob.LNX (came from Asus official .28 blob so redirect to the folder where you stored it)

5. nvflash -r --download 10 blob.APP (came from Asus official .28 blob so redirect to the folder where you stored it)

6. nvflash --resume --rawdevicewrite 0 2944 bricksafe.img (this came from when you originally did the nvflash setup so redirect to it)

7. nvflash --resume --go (the device will now attempt to boot stock but will go into a bootloop, by now you have the

stock TF201 bootloader back)

8. hold down power + volume down and wait for options then boot into fastboot

9. once in fastboot flash the recovery.blob for the CWMTOUCH, using fastboot -i 0x0B05 flash recovery recovery.blob

10. hard reboot by holding in power and wait for the blue bar to fill and the device to restart again

11. now boot into recovery

12. once in recovery you might find that cache wont mount and a lot of errors, ignore this and go to mount and format system and cache

13. now do a default wipe as if you were to install a rom. (factory reset, wipe cache, wipe dalvik cache)

14. once this is done you might want to adb push the sparky's .28 rom and install it but doubt it will work.

15. if it doesnt then boot into nvflash once moar and then nvflash -r --download 6 blob.LNX and nvflash -r --download 10 blob.APP

(these are the blobs that popped out of the sparky's rom blob)

16. once this is done just do nvflash --resume --go

If steps were executed you should boot back into plain old stock .28 for the TF201:fingers-crossed:
[Asus  Eee Pad Transformer Prime] lortay78:
Thank you so much for sharing those steps.
[Asus  Eee Pad Transformer Prime] wejgomi:
Hi. Thanks for all steps. But after all I cannot install CM10 builds and boot like I did before. It gets stuck on boot animation. Stock ICS rom boots ok but its old. Do you have such an issue ?
[Asus  Eee Pad Transformer Prime] JoeyDelp:
Havent tried CM10. Personally dont like it so much, busy doing the official JB update now as that was the purpose of reverting from the start.
[Asus  Eee Pad Transformer Prime] wejgomi:
The problem is there with every custom rom. They just won't boot. I think it might be something with cache problems in recovery. I remounted and formatted twice, I don't know. Maybe we are missing a step in process. By the way, having tried official JB, I can say you're better off with these custom roms. The lag is gone, but slugginish is still there. Wejgomi
[Asus  Eee Pad Transformer Prime] dj-bilbo:
hmmm... started the nvflash using both of these threads [htxp://xdaforums.com/showthread.php?t=1823106] & [htxp://androidroot.mobi/t3_nvflash/].

Got the first step of running the ...\ebtblob.bin cmd.

It rebooted in virtuous prime (but showes the correct “AndroidRoot 9.4.2.28r01" text. So i stopped it and rebooted in fastboot.

I sent the 2nd cmd ...\blobgen img and it's been more than 3 minutes and still no reboots.

It reads

"sending 'stagin' <4672KB>...

OKAY [ 2.396s]

writing 'stagin' ...

and there I am...

Is the reboot to rom the cuprit? what should I do?

PS: I also think i'm low on battery now...

Nevermind! i figured my cmd line was wrong! :D

[Asus  Eee Pad Transformer Prime] dj-bilbo:
I'm so close...

got to the wheelie execution file.

in windows, in cmd promt, (in nv_flash folder) I enter

"wheelie.exe"

I get the following lines:

"Wheelie 0.1 - preflight for nvflash.

Copyright <c> 2011-2012 androidroot.mobi

===============================

[-] you must specify --blob

So i typed

"wheelie --blob blob.bin"

And i get the above lines plus this one:

[-] failed to open blob file: blob.bin

any clue? not sure what to do now to pass this step.

Unless I'm supposed to copy the blob.bin file that i saved back in the same folder as the wheelie.exe file?

thanks

after more reading, i guess right. Had to copy/past the blob files created back with the nv_flash folder.

LOL, now i'm getting this msg "nvflash" is not recognized as an internal or external command, operable program or batch file.

I'm sure I'll figure out why soon... I hope!

edit: I did. i hadn't gone into the nvflash folder, thus the dos msg! lol

another successful outcome!!

Now on to flash twrp!
[Asus  Eee Pad Transformer Prime] wejgomi:
I think I found the cause. After following Joey's nvflash steps. Be sure to format your "staging" partition too in CWM or TWRP recovery. Then the custom roms work. Wejgomi
[Asus  Eee Pad Transformer Prime] Moe5508:
My wheelie executable keeps crashing just on step one...so basically am unable to bootstrap into nvflash using the wheelie blob blob.bin command. Was on HB 1.2 and managed to flash the stock JB but I need to flash the custom TWRP recovery now...

Device is in APX mode and connected to Win PC at the moment.

EDIT: A simple redownload of the NVFlash file pack containing wheelie executable solved the issue and I can fire up wheelie again with no crashes...
[Asus  Eee Pad Transformer Prime] JoeyDelp:
Just a quick update to my last steps, it seems all this is not necessary.

PLEASE DONT FOLLOW THESE STEPS WITHOUT READING THE LONG VERSIONS http://xdaforums.com/showpost.php?p=32134057&postcount=465

What i did last night in attempts to load up stock JB and bricking my prime a few more times I realized that all that is necessary for it to boot is to 1. wheelie --blob blob.bin. 2. nvflash -r --download 6 blob.LNX (found in say sparky's rom) 3. nvflash -r --download 10 blob.APP (also from sparky) and then lastly 4. nvflash -r --download 4 rec_bootloader.bin http://androidroot.mobi/download/rec_bootloader.bin, then just nvflash -r --go.

This should take you back to a stock rom and from there flash your CWM normally using fastboot and format system, cache, staging (thanks wejgomi, i forgot about that) then load up your custom roms and it should work.

Hope this helps

Noob help

Hello,

I was wondering if the recent update to android 4.1 JB for the tf201 has the same result as the JB update to the tf101 or the tf700, can I still go through the procedure described in the guide even though I automatically updated to 4.1 already? Otherwise do I have to downgrade in order to be able to go through with this? Thanks.
[Asus  Eee Pad Transformer Prime] lilstevie:
Yes, the JB update has the same issues as it does for the TF300 and TF700, and no, you cannot downgrade to do this.
[Asus  Eee Pad Transformer Prime] Blades:
After flashing the ebtblob.bin - I cannot reboot into fastboot mode. It literally freezes.. I can tell this because the selector is a blinking cursor, and it just stays frozen over the USB icon. Is this a common error? I do not make common errors.. If this is some how my fault I'll smash my TF201 and eat the pieces. I'm serious.
[Asus  Eee Pad Transformer Prime] RonH54:
I am sure this mentioned somewhere in this thread but should I un-root my Prime with Rootkeeper app before I perform NVFlash?

Thanks
[Asus  Eee Pad Transformer Prime] RonH54:
I got my Prime in Feb. and though I Rooted it immedialy I had held off Unlocking it for possible Warranty. After this latest screw up with ASUS OTA JB I decided I had had enough. I unlocked and got an NVFlash backup performed, files saved in 5 different places and I feel better..........:D Now off to get TWRP 2.2 on Prime and Flashing the GREAT Developer ROMS that are out there.

[Asus  Eee Pad Transformer Prime] ScottIsMyName:
So if we are on JB already, there is nothing we can do yet?
[Asus  Eee Pad Transformer Prime] RonH54:
I was never able to get OTA JB on my Prime. That is why I went ahead and unlocked it and got a NVFlash image so I could just forget about fooling with ASUS and get JB from a Custom Made ROM/
[Asus  Eee Pad Transformer Prime] Smurph82:
After a failed JB OTA I went ahead and unlocked my tf201and got the Nvflash files as well as the bricksafe.img. I then flashed CWM and then CM10. While I love CM the current nightly is a little buggy. I was wondering since Asus posted the official JB update on their website can I flash that blob file and run the official JB. If I do that would I lose the Nvflash ability that I just got?
[Asus  Eee Pad Transformer Prime] mrjarhed:

Watch this space! We're preparing an updated wheelie that can handle this scenario. (E.g. you tried really hard to brick your device :P)
[Asus  Eee Pad Transformer Prime] kwineon:
Is there anything in the works in the ways for a generic blob for recovering devices?

I got my tablet back from RMA yesterday and was excited to play with it. It updated to JB when I booted it, then when finding out that there isn't a working root method for it, I decided to use the ASUS tool and unlock it. Didn't get to do anything after it, it rebooted and now I am stuck on the ASUS screen (says unlocked in the top right, nvidia int he bottom left). And I feel I am SOL when it comes to an RMA.

Would the generic/full flash file have to come directly from ASUS?

Hopefully something can be figured out. :/

Thanks,

Dave

when i run this command from terminal emulator

$ nvflash --resume --rawdeviceread 0 2944 bricksafe.img

i get

/system/bin/sh: nvflash: not found

what do i do now?
[Asus  Eee Pad Transformer Prime] kmdm:
Okay.

Firstly, to complete the below process you absolutely will need Linux (we are in the process of building wheelie for Windows, however, the complete procedure outlined below simply does not yet work on Windows so that is a moot point).

1. Download http://www.androidroot.mobi/download/wheelie-0.2.tar.bz2

EDIT: I should probably say that you'll probably need to use wheelie thus: $ wheelie -r --blob blob.bin

This is the wheelie build that should successfully boot your device into nvflash resume mode, from there, if you cross-flashed the TF300T JB build you will need to completely re-provision your device by downloading and following the README in the following zip:-

2. Download http://www.androidroot.mobi/download/backtostock_tf201.zip

Once completed your device will be fully working and stock - from there you can continue as normal (please don't cross-flash TF300T ROMs - specifically bootloaders to the TF201). :P

---------- Post added at 09:31 AM ---------- Previous post was at 09:25 AM ----------

This is simply technically not possible - not even for ASUS or NVIDIA.

This is your problem.

(Hint: You don't run it from your android device but from your PC)
[Asus  Eee Pad Transformer Prime] ieftm:
1. Take head

2. Bash against wall.

3. Read the guide again, especially the part detailing where to run nvflash from.

quick question

HI guys,

So I ran the first 2 commands to create the blob files, I only see one blob fine and 5 others that just say local disk...how do I move those files back on to my laptop?

Not sure how to get to MTP mode.

Appreciate the help!

Thanks

**Never mind, I got them via adb**
[Asus  Eee Pad Transformer Prime] wwjoshdew:
I read that LOUD and CLEAR. You have stock EVERYTHING, but you have backups of the (8 I believe) files that the NVFlash process created. It overwrites the custom AndroidRoot bootloader so you do don't have a custom bootloader... How you'd access NVFlash, is still making me scratch my head. I guess you have the "secret codes" or something to access that part of your prime?
[Asus  Eee Pad Transformer Prime] mrjarhed:
Thank you

Thanks very much for this.

My apologies for not seeing this sooner; my brain's gone a bit weird searching everywhere for a way to fix this.
[Asus  Eee Pad Transformer Prime] Smurph82:

Tf201 stuck in APX mode

Hi Guys, I am after some help with my prime, I have done the nvflash setup and have all the files stored ok,but after flashing a JB rom I seem to be stuck in APX mode.I can wheelie into nvflash ok, but don't know the the correct procedure to repair my prime, I think that it's the bootloader at fault, tried holding down the power button for 30 sec's, no go with recovery or fastboot as well, any ideas?

After trying to repair the bootloader I now seem to have made things worse as I cant get into nvflash now, wheelie say that it is sending the bootloader, gets to 100% and sits there blinking at me with the prime saying it is entering nvflash recovery mode, but gets no further
[Asus  Eee Pad Transformer Prime] Blazeitup123:
Thanks man, this worked perfectly!
[Asus  Eee Pad Transformer Prime] frusso:
Same problem.

The only thing that works on my prime is the nvflash. I can run in nvflash mode but now i don't know what to do.

There was in same place a procedure to full restore ICS or JB starting from scratch (ie flashing bootloader, recovery, rom an so on) ?
[Asus  Eee Pad Transformer Prime] kwineon:
Okay, that kind of sucks.

Next question,

If I send it in to Asus, can they then remake the files necessary and reprogram my tablet? Or will the board be shot.

I seem to have lost my boot loader. :/

Also, is it possible to use NVFLASH to flash a boot loader blob from a stock release to restore the boot loader, then fast boot install CWM, then install a custom ROM? Or am I SOL?

Thanks for your help,

Dave
[Asus  Eee Pad Transformer Prime] tpdtopcop:
Hi all,

Have a quick question. I bought a used prime and noticed when i boot it up i have the android root in the left corner, however being that this is used i have no file that says android root with blob files inside. Do i have to do the whole thing over again, or just do this part..

finally time to generate your nvflash blob files with the following command:-

$ fastboot -i 0x0b05 boot nvfblobgen.img

Also can i do this using terminal emulator on the prime?

I just want to be sure I have done everything correctly before I try any Custom ROMs. I have used NVFlash on my TF201 using Fastboot commands via my Windows PC and I have created and saved the files it created. If I ever do need to recover my Prime from a Brick state using this files I need wheelie for Windows and that out yet for use? I am not clear on this restore point.

Thanks
[Asus  Eee Pad Transformer Prime] kmdm:
The problem isn't wheelie, the problem is nvflash.

If you need to recover from a fully bricked device you'll need to suck it up and use a Linux LiveCD or if you can't manage that I'd strongly recommend you stay stock ;)
[Asus  Eee Pad Transformer Prime] RonH54:
Thanks for reply. I have No problem staying with Stock in that I have been one of the lucky ones were I have had no really problems with my Prime for the things I use it for so I am in no rush to really do anything.. I just have always loved the Custom ROMs guys had created for my SG1 phone and want to try CM10 on my Prime just to see it. Am I correct in that something will evenually be created where I can use PC to restore a NVFlash and not have to use Linux?

Thanks again
[Asus  Eee Pad Transformer Prime] kmdm:
Who knows what the future holds?

Bottom line: If you're not happy with using Linux to restore - DO NOT DO ANYTHING THAT MIGHT CAUSE A BRICK, SIMPLES! (Easiest way to do that is to stay stock!)
[Asus  Eee Pad Transformer Prime] RonH54:
When I Google "Linux Live CD" and there are lists of several ones it seems. Which Linux should I get if I do indeed try something and need NVFlash restore. I have no fear of running Linux commands if it needed.
