Why don't you use the correct firmware for your device supported from the ASUS download center?

Please go there. Figure out the firmware for your device. Then try again. http://www.asus.com/Tablets/Eee_Pad_Transformer_Prime_TF201/HelpDesk_Download/

Hi guys. My TF201 suddenly stopped booting into OS. Its unlocked some years from now, never had problems. Now it's stuck on a bootloop and when you power on, goes directly to recovery but twrp isnt working and restarts again.

I cant access fastboot either. Either I turn on with vol- pressed or just power on without anything else, twrp tries to launch but restarts again in a loop.... I tried the paper clip tiny button, same thing again. I tried everything, even with sdcard with asus original blob, cant boot from sdcard... im out of ideas...

Cant boot from sdcard, cant access recovery, cant have fastboot mode...

Can u help me?

any way to flash tf201 with power off just usb connected?

[IMG="Tf201_usb_poweroff"]https://s22.postimg.org/vqx2u03lt/tf201_usb_poweroff.png[/IMG]

I get this when i plugin tf201 with power off... I would only need .. usb driver and software to flash... anyone?
[Transformer TF300T Q&A, Help & Troubleshooting] berndblb:
Is there any particular reason you posted this in the wrong device forum (this is TF300, you have a Tf201, right?) and in a thread that has nothing to do with your problem? :p:cyclops:

But I'm just needling - never mind....

The only way to recover from this I know of is with _that's bootit.ko.

APX mode does not help you unless you generated your nvflash blobs way back when and stored them somewhere for safekeeping and a situation just like this one. If you don't have them, forget about it. They are device specific and now it's too late.

There are a couple of things to try.

lj has a thread describing how to use bootit.ko here: http://xdaforums.com/transformer-tf300t/help/guide-t2854495

Yours truly wrote a similar guide on a different forum here: http://www.transformerforums.com/fo...my-transformer-tf700-boots-only-recovery.html

If you follow lj's guide, the second part (flashing the Asus firmware in fastboot) is optional. If you get the tablet to boot into fastboot and you can erase cache and misc, you could also try to just flash TWRP again and flash a rom. Flashing the firmware in fastboot restores every single partition to the factory default, so that's the safe but also the long option. Because once you get the tablet to boot into the stock rom, you have to reflash TWRP, in your case possibly the Hairybean bootloader (don't know which rom you were running) and then the rom. Your choice.

Now - you have one added challenge: Both guides assume that you have adb access in TWRP.

If TWRP reboots on you, you may have only a very small window of time to perform the adb push of bootit.ko and the insmod command.

Watch it with Device Manger open: let the tablet loop and check if at any point you have adb access. Time it. Use a stop watch or tap your foot and count or whatever rocks your boat.

This could take many, many tries, depending on how good your timing is and how long you have adb (if at all). You don't have to get both things done in one window. Try to adb push the file to the tab first, then worry about the insmod command.

I have seen this work in a situation like yours a few times. Takes persistence and luck. Which I wish you plenty of...

Oh, and if you do not have adb in recovery at all - sorry, but I think you would be SOL in that case..... :crying:

So.. I think I bricked my device :(

Selected the "Wipe Data" by accident on the bootloader menu, so now my tablet, starts on asus logo, then four Linux penguins appear with a legend and then it changes to the TWRP recovery project screen, stay there for about 20 seconds, and then it restart again with the same, on and on and on, until battery rans out

have tried the methods described here

fastboot -i 0x0B05 flash system blob

< waiting for device >

fastboot erase recovery/system/misc/etc...

< waiting for device >

adb reboot bootloader

error: device not found

adb reboot bootloader

Yes, maybe a little off-topic and surely not for tf300, but i think it applies to tf300 also... Well... i can't access adb, as it doesn't even for a second open port(s). I tried for several times in windows cmd adb devices... well... nothing yet. It would be nice if its chip was mediatek, so I could flash it without the need to power it on... is there any way to do this as a "generic image"? (ASUS website has got blob files to upload to device, but these aren's those, are they?).. so, im loosing hope... no adb, no fastboot... thank you for the guides above, but they couldnt help me yet.
[Transformer TF300T Q&A, Help & Troubleshooting] TiagoDM:
Ok, thank you all but after I read lots of information about this, and having no blob.bin previously from the device, the only thing that i think off is sending this to ASUS... I didn't wat to spend money... or maybe I can buy a new tablet with better performance... thank you all anyway, but I don't think there is much to do with it, I dont "speak" assembly, so, im done.
[Transformer TF300T Q&A, Help & Troubleshooting] Nektopoli:
Ok, look as though you can still send command to the tablet and it will execute them, when you tried the 'fastboot -i 0x0B05 flash system blob' command what was the 'blob' file you were trying to flash?

Don't, not yet. You need to see if you can send commands to the table from a laptop/desktop. If the tablet can receive the command it should be saveable.

I did something, and looks like ADB is working, but not completely

I tried "adb reboot-bootloader" and it did nothing

but it is sending files and it is responding to the "adb devices" option

tried with the blobs and the zips containing the blobs, but it says no androidmanifest.xml is there...

any idea?

Hi.

Today when i power on my tf300t stuck at Asus logo. I rebooted it from the reset hole with the same result. Then i entered in recovery (stock) and try to flash from sdcard latest firmware from Asus site. I have the progress bar runing and the tablet is restarting after the progress bar is near the end, but with no result (the tablet remains stuck at asus logo).

The bootloader is locked, and I have acces to fastboot, no adb.

I followed the Buster99's method, but I can't erase misc and can't write the blob file, in both cases the tablet freezes and I ended with Unrecoverable bootloader error.

Is there anything else I can try?
[Transformer TF300T Q&A, Help & Troubleshooting] berndblb:
Unfortunately not. With a locked bootloader fastboot is useless to you. It won't let you make any changes to any partition. Believe me, we have tried very hard to get around it, but failed miserably.

Make sure you are trying to flash the same firmware or newer, but you probably are. Otherwise the recovery would not even start to flash it.... Something else is not working and I am afraid only a new MB is going to bring this back to life...
[Transformer TF300T Q&A, Help & Troubleshooting] multiSingularity:
It works! It's a miracle.

Thanks a million buster99. This resurrected the corpse of my TF201 after all hope had been lost, and other posts assured me that my tab was hard bricked. Not so much it seems!

Now I'm back to stock 4.1 and ready to root 'n' flash.

I had this problem as well if i entered the stock recovery I would get a dead droid and Error! However I was able to get into the OS and I was also able to make a connection from my PC. So using ADB and Fastboot I was able to load the current version of TWPR, this made my error go away I now have a working recovery and I have root.

I downloaded twrp-3.0.2-0-tf300t.img as recovery.img and put in my C:\Android\sdk\platform-tools> directory and my device. (Not sure which one it uses so I put it in both to be safe)

opened an administrative command promp in the C:\Android\sdk\platform-tools> directory.

adb devices

(Which showed my device was connected.)

fastboot -i 0x0B05 flash recovery recovery.img

(will show waiting for device)

Manually restarted my device to recovery (Hold power and volume down).

as soon as my system went into fastboot adb started flashing the recovery. after jumping threw a few setup hoops I was good to go and up an running with the latest version of TWRP.
[Transformer TF300T Q&A, Help & Troubleshooting] Butzacooky:
Hey guys I wanted to give my experience regarding this issue. I tried to use a tool to root my TF201 that bricked my tablet halfway through. I had an unrecoverable bootloader error with 0x0000000... I followed Buster99's instructions the first time without installing android sdx drivers. I don't remember what step didn't work as it was a week ago, but I do remember that I didn't get the reboot command to properly register on the tablet). I then installed the drivers via that F8 reboot to disable drivers enhancement or whatnot. Then I downloaded the latest US firmware 10.4.2.18 FOR MY TF201 (please use the appropriate firmware for your tablet version) and unzipped it twice to find a file named "blob". I followed Buster's steps again and it worked - through and through. I'm back at stock firmware (with my bootloader still unlocked).

Thanks Buster99!

Hello, am I to download files to a pc since you say to make a folder on the c drive? Extract “Minimal ADB & Fastboot” and install it on the pc? Or, am I doing this on the SD card since I have no access to recovery mode on the tablet. It seems stuck on the team win recovery project when I do the power button and volume down buttons. I can't even shut it down with just the power button. Thanks for your help.. Cindy
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
When your tablet turns off during the boot loop try to hold the volume down button for a long time in order to get into recovery when it turns on again. The three icons RCK Android Wipe Data should appear. In the left upper corner should appear the message

"Starting Fastboot USB download protocol"

.

When this message and the three icons appear, you'll have access to the device via USB through your PC and you can rescue it.

Should the action fail your tablet is bricked totally. Bricked means there is no chance to get access into the tablet. It's like a door is walled up by bricks.
[Transformer TF300T Q&A, Help & Troubleshooting] berndblb:
Yes, you download and install Minimal ADB&Fastboot on your PC. Those are two low level protocols used to communicate between Android device and PC. You use fastboot when the tablet is in fastboot mode, that is the screen with the 3 icons, and adb if the tablet is in recovery or booted into Android. You also need to have the correct drivers installed on your PC. If you are lucky you have them already - just try it. Otherwise you need to install them.

If this is your first time with adb/fastboot it's a steep learning curve, but take your time and it can be done. Google for a tutorial on both - there are plenty around.

This rescue method here is based on fastboot, so you need to get your tablet into fastboot mode. If you're stuck in TWRP you may have access to adb. If 'adb devices' returns a string of letters and numbers, try to boot it into the bootloader with 'adb reboot-bootloader'.

Good luck

[Transformer TF300T Q&A, Help & Troubleshooting] berndblb:
This can be an annoying problem and you may have to try several driver packages, uninstall them if they don't work and try other ones. The drivers from the Asus PC Suite were for Windows XP. They may and may not work anymore - depends on your Windows version.

As you found out, you want to stay away from all these driver downloads sites - they are usually infested with malware.

You could try the Universal Naked Drivers from here: https://xdaforums.com/google-nexus-5/development/adb-fb-apx-driver-universal-naked-t2513339

I believe those are the ones I used when I moved to Win 8 and then Win 10. If you have the 64 bit version of Win 8 or 10 you have to disable Windows driver verification feature to install them: https://www.youtube.com/watch?v=71YAIw7_-kg

Oh my... You do need to get adb working, I know only of one way to get out of that loop and it involves a couple of steps in adb. Check out this guide: http://www.transformerforums.com/fo...my-transformer-tf700-boots-only-recovery.html
