[HOW-TO] Unbrick your Transformer Prime (or not)

[reexon]

Newbie in need for help - Unknown BRICKED State….and Unknown how was bricked

ASUS TF201 / 64 gb. – No access to specific blob files.
I think I have APX mode after I run the below commands in Ubuntu

lsusb...
Bus 002 Device 085: ID 0955:7330 NVidia Corp.

and when I run
dmesg |tail

I have tried Windows before Ubuntu, I was able to identify as APX in device manager but I could not understand and get any results, and decide to move to Ubuntu.

I appreciate if I can get straight answer that I can’t seem to find:
Since it’s visible as APX in ubuntu and Windows what are % chances to be recoverable?

I’m newbie and I have tried to learn as much as I can…but after a week of frustration I’m very down on energy, and lost …in commands that don’t seem to work as specified on forum.

I appreciate any help and direction on where should I start.

As of now the chances are exactly 0% if you don't have backed up the nvflash blobs.

Two posibilites:
1. Buy a new logic board at ebay ($ 30 to 60)
2. Hope on outcomings in this thread: http://xdaforums.com/showthread.php?t=2178110

is this brick??

Till yesterday I had namidario cm 11 rom, 4.1.1 bootloader last version of voyager TWRP and kokokernel. Everything worked pretty good.

Yesterday and today I tried to flash PARANOID ANDROID 4.4 and it went on Framwork_res_Stock_20140608 loop, than I tried to intal the previous PA 4.3 version (and the Framwork_res_Stock) and it went stock on asus splashscreen. Than today I tried the new namidario CM11, but the same asus splash screen is stucked there...

What sould I do?
Is it another type of brick?

EDIT: I saved the day... just wiping everything I could, and flashing again the namidario's CM11, but previous version and it worked again...

Sorry for my english.

Hello,

I Will pay if anyone really help me with success to unbrick my TF201, really !

Thanks a lot,

You are my last hope....

I'm looking to update to later JB bootloader so I can try Androwookie again and or new KIT Kat Rom I just seen. Currently on older Energy Rom and its been stable but cant stream and use bluetooth audio without video being streamed stopping. I want to see if a more updated ROM would help with multitasking..

I've done this update before but don't want to risk bricking after reading this thread. I have bricked mines before and spent a whole day, (took a day of work off!), on this thread til I got it back. So good luck to anyone this happens too.

My question is there a more recent update to use NV Flash? I remember looking before and it was too complicated for me to follow. I noticed this was updated 2014 but not sure if anything really changed. I just want to have something to go back to in case I mess something up!!

Thanks

TF201 Bricked Brick 1a / 1b ?

Hello,

My Transformer prime always boot to the same screen (green robot with rotating gear) No text and nothing append:

I can connect the tf201 to the computer with adb but not with fastboot.

So I try the brick 1a solution and brick 1b but no good result I can't enter in other recovery mode like with cwm.

This problem appeared after I've done wipe user data because AndroWook always reboot my pad.

Here is the command I used :

C:\tmp\Upgrade ASUS transformer TF201 android UBTv1.3.2>adb shell
~ # dd if=/dev/zero of=/dev/block/mmcblk0p4 bs=100 count=1
dd if=/dev/zero of=/dev/block/mmcblk0p4 bs=100 count=1
dd if=/dev/zero of=/dev/block/mmcblk0p3 bs=16 count=1
dd if=/dev/zero of=/dev/block/mmcblk0p3 bs=16 count=1
^C
C:\tmp\Upgrade ASUS transformer TF201 android UBTv1.3.2>

When I reboot, pushing volume down and power don't make it enter into recovery, each time it's the green robot.

Please can somebody help me ?

CanI reinstall cwm with adb, without fastboot ?

Thank you very much.

Good evening every one.

Well, owner of a tf101, i am trying to help afriend who has a big problem with her tf201, but did not find any solution yet:

Her tf201 is stock rom, she only made stock rom updates and she thinks she has the latest one, but i cannot chek it since....all of a sudden, she turned her device off normaly one day, and she's got bootloops the other day, any time it comes to ASUS logo it reboots again and again.

She never did anything, no unlock bootlocker, no cwm, no twrp, no Nvflash preinstalled....just stock situation.

Of course she's got files she'd like to save like photos, etc....reason why the only thing i did not try is wiping datas. Cause yes, i am able to load stock recovery pushing volume down and power.
I downloaded the latest stock rom from Asus site, installed it on Sdcard to try to reinstall the firmware. The installation seems to begin, but after 2 or 3 minutes, bootloops are back again.

Could you please tell me what you think about all this ?

Thanks very much in advance.

Still Sick

I was in the basement and ran across my paper weight. Figured I would check back into the thread to see if someone smarter than me had stumbled across a fix. I had forgotten about it, but the sick feeling has set back in right before Christmas.

I am having this exact same issue, did you ever find a fix?

I am having this exact same issue, did you ever find a fix?

Have you tried "adb reboot bootloader" ?

Brick 2: When booting up your Prime hangs at the splashscreen (the screen with "EeePad" in the middle) and tells you something about an "unrecoverable bootloader error" (happened so far to at least 4 users)
-> Please go to Option 2
Option 2

Sorry, but your Prime is most likely hard bricked.
This can happen if you try to apply a stock blob file after you installed CWM. There is currently no way to recover from this

I have same problem, Can anyone help me? :'(
tks everybody! :good:

Can anyone help me?
I was in the 4.1.1 but the tablet started to be amazingly slow, so I did the root and unlock with the asus software.
After I tried to update to a new rom with goomanager and the pad rebooted. Now is stucked into Asus logo with "the device is unlocked" on the left corner and "powered by tegra" in the right corner.
I cannot even turn off the device. If i press the power button it restarts again.
I'm not able to go to recovery or fastboot. Its always in asus screen.
What can I do??
Thanks

Unbrick

I think you should forget about that. I did exactly like you 2 years ago. It was really slow, so i tried to get it faster and now is always in loop mode. No solution in the past years. Today i start cleaning for moving between houses and i found my old transformer and i came here to check, because it kills me knowing i need to throw this away and i have the transformer with the battery keyboard docking station.

yah i throw it away too, it's time-consuming
i have just bought a new tablet :"))

 

[Rushing]

This was the most high end tablet I hope I ever have to trash.
It sucked in the beginning with stock, it sucked with root, it collapsed with cyanogenmod. and yeah I did all the somewhat tedious backup of the needed restoration files. But it wouldn't be worth it to restore the fail Asus made.
I will take it apart and look at the old gpu for fun.

[scroeffie]

i can only get in to apx mode on my tf201 any tips !

 

[j0p3y]

I'm into a bricked state where the only screen I get is the black screen, in the center it says in white "Asus® Inspiring Innovation - Persistent Perfection" and in the bottom-right there's the 'powered by Nvidia'TEGRA' logo.
I can't get the tablet to shut down.
I can get into bootloader mode with four options by pressing power+vol-down for 10 seconds.
Selectable are RCK, Android, USB and Wipe data.
I like to update to KatKiss 7.1 (https://xdaforums.com/transformer-tf700/development/rom-t3457417)
I haven't used the tablet for some years because of the terribly slow preformance. Had it replaced for an iPad for some time. That device is gone now (!) )
I didn't root the Transformer Prime when I used it.
Now I like to try to revive the device, are there any instructions so I can get it working on KatKiss?
I'm a bit familiar with rooting and ROM flashing.
This device is non-essential, so I have my hands free to try whatever it needs
