[Q] Need Help Unbricking - Transformer TF300T Q&A, Help & Troubleshooting

I just got a transformer pad tf300t, and i am new to android, and just the other day i managed to brick it. i have searched for hours on end for a way to unbrick it, but all the methods i can find don't match my circumstances. So far all i have managed to do it get it into APX mode (i don't know how), and installed a driver so that in Device Manager it says "Asus Transformer Prime APX Interface". Whenever i do volume up+power button, or volume down+power button on boot, it reboots and returns to the boot screen where it stays forever until the battery goes dead. This all happened after i unlocked the boot loader, attempted to install clockworks, and then the battery went dead while using the wipe system data option in the boot menu (or whatever it's called when you do volume down+power button). Any help would be awesome and i would greatly appreciate it.
EDIT: Just sent an email to ASUS about the problem, and of course they weren't any help and just said i might need new hardware (hopefully not true)

Hi, i've met the same problem.
In fact when i tried to update my TF300T to JellyBean, my device didn't want to boot anymore only in Recovery or on Bootloader. So i tried to update the Recovery with the fastboot and install a TWRP recovery with Fastboot in USB and tried to re-install the ROM (CM 10).
But after that, Recovery and Fastboot did'nt work anymore. I've made a video to illustrate the problem (youtu.be/9aSWZrkP_Ec)
This is like that in Loop untill the device has no battery left.
Sorry for my mistakes, i've got an aproximative english
Thanks for any help.

To the OP, if you can some how push a new boot.blob from a ROM and then push a new system blob from the stock firmware, that fixed it for me. I could get into recovery still though so I used fastboot to do this.

[Q] I need help! My TF got stuck and can't boot into recovery!!!

My Tf got stuck at the logo Eee Pad boot after I tried to restore the old rom, and now it can't do anything except boot and stuck at the logo.
I tried the nvflash unbricking technique from rayman84 : http://forum.xda-developers.com/showthread.php?t=1123429
, but my TF only listed as unknown device when I tried to get to APX mode and it also said,
"This device is disabled because the firmware of the device did not give it the required resources. (Code 29)"
Now I don't know what else to do. Please help! I hope I am not completely bricked the device yet.
Have you tried the button combo to get into recovery?
Press and hold the Vol down + power button.
When prompt, you'll see lines of words at the top left of the screen, push the Vol up button immediately within 5 sec to get into recovery.
Apparently, I didn't know the button combo. Anyways you save my niece's TF. Thanks a bunch
Edit: although the tablet is working now, it still got the message usb unknown device. Do you know how to fix it?
Hi, i don't know if i should post a new thread but my problem is almost the same as bengob3t's one.
I have a brand new TF101 with a B70 Serial number, but i successfully rooted it using the RazorClaw Tool. Then i tried to install clockwork mod followin this topic : http://forum.xda-developers.com/showthread.php?t=1106587
I directly applied the instructions from step 8 (download hashmyfiles etc...) and i rebooted my Eee pad manually step 13
I didn't see any progress bar, but my device is stuck on the Asus screen, and the speakers make stange noises at regular intervals.
I am able to go into recovery though (power + vol down then vol up) but the factory reset doesn't work, and i cant really do anything (at least not anything that i know what it is).
Is my tablet definitely bricked ? If not, how can i bring it back to life ?
I wasn't able to use NVFlash, as i can't seem to go in APX mode. I press power+vol up, i hear the sound usb device connected and immediately after i hear the sound "usb device disconncted"
Nvflash says
"Nvflash started
rcm version 0X4
Command send failed (usb write failed)"
Thanks in advance for your help.
EDIT : When i put the micro sdcard from my phone into the tablet, i am able to mount it. So i will probably be able to flash something from it, but what ? Do i have to flash a recovery ? Directly a custom rom ?
I'm a little lost, but i'll try to give you guys as mush info as i can find.
EDIT2 : I flashed the PRIME rom, everything seems to be back to normal... if you got info on my situation, don't hesitate to fill me in ^^ i'd like to understand what i did wrong, even though i dodged the bullet.

Do you have the correct driver installed? Do you have Asus sync install on your PC?
hmm.. I'm not sure. I downloaded the unbricked tool nvflash file, and the tool already had usb driver inside it. Is that the driver you were talking about? I never were able to get to the point where I need to point the APX to where the driver located because it always said unknown driver the whole time.

Broken CWM

I have flashed the CWM from TF201 by accident. Now the tablet is stuck in that CWM mode. I can't connect to usb using adb mode. Power+volume down does not work anymore. Any way I can reflash the correct CWM?
THanks
If you can boot to OS - you can use fastboot to flash any recovery.. or flash TWRP from goomanager.
upd: sry..don't see about "stuck".

I have made the same mistake. Although I can get the device to fastboot USB mode. I have tried to use CWM with the restore I made before I put in Cyanogenmod 9, as well as putting on the Cyanogenmod experimental #2 for TF300. No error messages at all and it wipes data and cash without any problems.
But I get locked on the Asus boot screen and it does not continue ie I am stuck as well.
I have as well tried to use the TWRP 2.1.5. I get the Teamwin loggo screen, it wipes all the data and verifies all the filesystems and reboots. Still stuck.
Is the device bricked ?
upd:The TF300 can not be shutoff either. When you hold the power button the screen goes black, but after ~5 s the device is starting again and is still stuck on the Asus bootup screen.
if you reboot it holding vol down and power, can you get back into the boot menu, to reselect fastboot?
if holding the power button doesn't switch it off, what happens if you leave it to run out of batteries then do this?
then you can flash the correct recovery.img

Yes, I can get access to the fastboot and I have already tried to flash with the recovery.img. I have as well let the battery run out and tried it once more with the same result.
Still stuck on the asus bootup screen.
power
Hare,
I have same problem.tab cannot power off. Just reboots into cwm.
I was thinking to drain bat. Thanks for sharing that info.
There are a lot of topics about people who broke their devices with TF201's recovery.
Afaik, no one recovered it. Send to Asus.
So the device is bricked then :'(.
Thanks for clearing it up.
Sent from my GT-I9100 using XDA
RMA..
Guillaume,
Thanks for clarification.
I have read that ASUS wants 700USD for replacing/reflashing the bootloader. That was for the tf201. Any way to nvflash it back to factory? I don't believe that they have to change the MB.
I have no warranty left, but I don't want to be gouged by them either.
Any thoughts, info?
Hi,
I've do the same mistake, but I can use adb.
Do youhave any news about our problem?
Thanks
Midyr
unable to power off
My issue is that I have the CWM for the tf201. I did the update from the CWM app in Android. Bad idea. So now the tab does not power off s.t. I can get into the power+vol down mode. Adb does not work since I cannot ( don't know how) to make it go into the usb debugging mode. I have tried several things none of which have worked. Still stuck.
I wanted some feedback for a RMA from ASUS, posted it here but sor far no answers.
Not sure if it would really work, but on my Evo, I don't have to completely power off the phone to do the recovery sequence. I can do it during a normal reboot. There is a point just before the device starts booting again where it is technically "off", and if I hold volume down (don't even have to hold power on my Evo; volume down seems to be the only necessary button) starting at this point, the phone will boot into the bootloader.
So, next time the device reboots, just start holding volume down (possibly power also, just in case) at the "off" point.

[Q] Can't access fastboot only APX

Hello, I have always been able to solve any issues from forum posts but haven't been able to find anything specific. Any help is HUGELY appreciated!
I was attempting to flash some 10.1 CM, so I went to the stock recovery and did a wipe data from my previous ROM and start clean. It rebooted without giving any indication and just hangs on the ASUS screen. The device is unlocked and I see that in the corner but when I try and boot using POWER + VOL DOWN it just hangs there without giving the typical recover options. I saw the nvflash but it looks like it requires me to go into fastboot at the outset. I can use POWER + VOL UP and the device shows up in APX.
As I have not used APX, I not quite sure of its capabilites. Is there a way I could flash a custom recovery image using APX or am I SOL? Thanks again for any help.

Need help with xoom, possible brick

First,
I really want to thank everyone for their support in this forum. Everyone has been amazing.
I was trying to bring my MZ601 back to stock yesterday. Something bad happened during fastboot and asked me if I wanted to unlock my device. Then the screen locked up and didnt do anything. I rebooted the device and now it gets stuck in a boot loop with the EOS symbol (last rom I installed). When I enter recovery there is nothing there, all of my data is gone.
Worse the device is not recognized on my computer nor can it be found in adb fastboot. I have updated motorola drivers, but I think the device never gets past a certain point in order to be found.
Can somebody please help me.
Thanks,
Pretty impossible to brick XOOM's but i'll ask the basics. Can you get into recovery from a cold boot? Can you get into fastboot from a cold boot?
By the sounds of it you've just corrupted your rom or tried to re-unlock the device which would cause the entire sdcard partition to be erased.
Boot XOOM into Recovery, Fastboot, or RSD mode
So you need to get into Recovery to backup your XOOM (you do nandroid don't you?). Or perhaps you were working on creating new levels of awesome and something happend and you find yourself staring at the Motorola Dual Core boot screen with your XOOM refusing to boot any further. Fear not, you are only a few clicks away from finding your way back into recovery or fastboot goodness.
Turn your XOOM off
Press Power to turn your XOOM back on
When the Motorola Dual Core boot screen appears tap Volume Down repeatedly until "Android Recovery" is displayed
Press Volume Up to enter Recovery
You can also choose from Fastboot protocol support and RSD mode by using the same method but instead selecting their respective menu prompts.
Note:
If your XOOM is caught in bootloops or you find yourself stuck in RSD mode or Fastboot Protocol support you can hardware reboot your XOOM by pressing and holding Volume Up + Power until the tablet reboots (usually a few seconds but could be longer).

Hi,
Thanks for the tips. Unfortunately, it seems that I have caused the entire sd card partition to be erased. That mean when I trry to fastboot my device is not recognized. Also, i cannot add anything to my xoom through usb. I have tried to flash through the external sd card, but to no avail. What do I have to do?
What does your xoom show up as when plugged into your pc APX? Can you boot into fastboot mode. with power off press power and volume down until you see fastboot.

Hi thanks for the reply to my message.
Unfortunately I cannot find my device when it is plugged into my computer (PC). It does not show up on my computer nor in the device manager. I can start the fastboot protocol on my device by rebooting, but I also cannot find my device in ADB.
Thanks for the reply, but I am still very stuck.
are you sure your device is in fastboot ? did you reinstall the drivers, try with another usb cable, adb shoud see the device after the drivers were installed correctly ...

I did everything I have done before. I have setup android sdk, java, and motorola drivers on two different PCs. Both fail to find my device when i type ADB devices nor does ADB reboot bootloader work. I tried the different cable, but that also did not work.
Hi,
I see that your problem is quite hard, try doing this:
1 - Force your tablet to shut down (vol+ + Power)
2 - Turn on while holding the vol- button
3 - Keep pressing vol-
4 - Plug on your PC and try fastboot devices, adb won't work!
5 - If 4 didn't work, keep trying until it does
6 - Install a Stock ROM (so you will solve your problems)
If the above don't work, contact me via PM, so we can talk easily (maybe GTalk or something like this). Good Luck

XxLordxX thank you!!!
I took your advice and just used fastboot. Then I flashed the stock rom I wanted to use. My xoom is back up and running. I really appreciate the tip.
Also thank you to everyone that responded in the post, again, that is why I love coming here.

[Q] no fastboot no adb wrong drivers?

WHats up guys? My tf300 is still bricked after like 6 months. It started with me flashing the wrong recovery image then a wipe data finished it off. I can get into apx mode and device manager sees it as an apx device with a yellow triangle, or as several different names according to which driver i use. I have tried all the asus ones, the adb, the composite adb, all the ones from the naked driver set. No matter which ones i use fastboot devices returns nothing and adb devices says "list of devices attatched but nothing. Is there something wrong with the way im using fastboot? I just go to the fastboot folder and open a cmd window and it starts like C:\user\fastboot or whatever and im stuck there please help

Questions: what rom did you have before? Did you wipe data from the Asus menu, and not from inside a custom recovery? When you now try to get into fastboot by holding volume down + power, what happens? No matter what, try Buster99's solution. If the only mode you can get into is APX, and you didn't generate NVflash files, then I'm afraid your motherboard is stuck, the only solution to which is replacing it.

Must've been the wrong recovery that screwed up your tab. In my experience, wiping data from the Asus menu while you're on stock rom is not supposed to brick it as described by you. Try this method. It has saved quite a few semi-dead tabs. Good luck, and give thanks to the author if it helps.
