[fixed] Did I brick it?

Hi there. I was fooling around with my TF300T (I was foolish at some point, probably) and managed to install Jellybean using this method. It started working fine. So it did that I restored my files using Titanium Backup Pro, installed from the App store right after the first boot. The apps/data I restored with Titanium Backup, as far as I can remember, were mostly games and Dolphin stuff, nothing directly related to system, as far as I know.
After this backup restoration, I used the tablet a little more, played the games to check if my progress was not lost and all that. It worked, Angry Birds at least had all the levels I completed before yet marked as completed after restore the procedure.
So far so goo... no! For some reason I can't remember I restarted the tablet, at least I tried! It got stuck on the loading screen (the white Asus, not the shiny one). So, after that I tried to restore it again, and then I probably did something completely stupid and I can't even remember what.
I even tried superwipe on it, but that didn't work neither.
At this point my tablet let me flash recovery image, CWM and TWRP. I can use adb shell with CWM but not with TWRP.
For some reason, I don't know, when I use CWM it doesn't mount /sdcard, TWRP seem to be mounting it, but go figure, I can only access the /sdcard that TWRP mounts using TWRP, if I change the recovery to CWM for some bizarre (or obvious to you guys) reason, I can't mount it.
And no matter what recovery I use, I can't flash any ROM. Both recovery tells me it was flashed, no error message (at least not at the screen) but every time it reboots to finish the installation, I see the Asus logo with a progress bar that goes from 0% to 100% in less then one second, and once it's filled, the tablet reboots itself and show me the regular boot screen with the Asus logo (again, the white one, not the silver-shiny).
So, resuming my problem, I can fastboot and adb shell it (adb only with ClockWorkMod Touch), but flashing doesn't seem to work. And I believe the internal memory/storage structure have been compromised.
How do I fix this?
Here is what I did to fix it

Download a cm9 rom, open the zip file and extract boot.blob . Flash with 'fastboot -i 0x0B05 flash boot boot.blob' then reboot...

Looks like partition sizes chaged with the Asus update. I couldn't flash CM10 or any other rom as well (signature mismatch). If you installed the official 4.1.1 update, you need to manually install it again. Older versions and rollbacks wont work unless you push to some trickery mmcblk0p4, but that's another thread in itself
Download the JB update from Asus's website (if you still have it, that's fine) and extract the blob file. Put the blob file in teh same directory as your fastboot. Boot your TF300 into bootloader and enter:
fastboot -i 0x0B05 flash system blob
It will take a while to install, so be patient. Hope this helps

Doing it now. I'll update as soon as I finish it. Thank you very much for your reply.
UPDATE 1: I can see the shiny-silver ASUS and the progress circles, waiting to see what happen!
UPDATE 2: Setting up Jellybean now (Welcome setup)!
UPDATE 3: Looks like it's working!
Dude, thank you so much! I'll fool around with it. Is there a root method working already? I was wondering if there's a way to restore my backups, at least the ones I made for my gaming progress.

Man you saved my life. Thank you very much!

When i try it i get error: "Failed to process command flash: system error(0xa)"
any help?

Thank you for posting this thread, I wasn't paying attention one day and flashed the wrong version of something and ended up stuck on the white Asus logo. Flashed a ROM's blob via fastboot and was up and running in no time, though it did take 2 attempts, the first time it received the blob but failed to write it.

I recommend you to use the CleanROM 2.5, it's stable and fast! Really fast! Faster then the ASUS Stock ROMs. I'm really enjoying it.

Still can't flash ROMs
Thanks so much for this. It really helped to get me back to where I was. However, I still can't flash any roms besides the stock asus jb. What can i do? I've tried several different ROMs. I still get stuck at the ASUS "The Device is Unlocked" page

For CleanROM he'll need a specific TWRP version. It's better give CleanROM thread a read before install it.

I'm having the exact same issue as you did. It just will NOT let me flash the stock JB rom. The tablet tells me Failed to process command flash:systemerror (oxa) and command prompt says

1. Please, make sure the Tablet is the only one Android device connected to your computer
2. The bootloader is unlocked, right?
3. It's not the matter (almost impossible to be the case), but what are you using as recovery, TWRP or CWM?
4. Are you trying to flash the Official ROM?

No you haven't you need to download fastboot and connect the tablet to your computer, on that screen just let it sit their.
Download the asus firmware. Follow the flashing fastboot guides here. You need to flash the blob file.

Hi, I have the exact same error message after installing the latest firmware from asus (ww_epad-10.6.1.8-20130225) and flashing cwm recovery.
Flashing via fastboot works fine and I have already reflashed the blob file and reflashed cwm recovery. still the same issue: "Key driver not found" and upon chosing entering RCK it freezes. OS boots fine, no issue here. Any clues? Should I flash the stock kernel from Asus?

well, I am using a win xp machine for fastboot. so I don't have the same issues. fastboot works fine, so that I use the normal fastboot process to flash the system and the recovery kernel.
I finally got it to work again by flashing the newest TWRP instead of CWM. It seems CWM does not yet work on the latest firmware.
I followed this guide for flashing TWRP with fastboot. This version actually also just asked me, if I want to root the device, I clicked yes and it was rooted. Perfect.

I am in EXACTLY the same boat as you. The only difference is that I flashed TWRP instead of CWM. I finally decided that it was time to root my tablet...got tired of the lag. IIRC I've gotten the "key driver not found.. booting OS" error message since doing the OTA update to 4.2 (I did this prior to rooting.) Everything SEEMS to be working okay, but this bugs the heck outta me, and I'm sure it can't be a good thing. Hoping somebody will chime in with a fix for this. I've searched and searched to no avail.

Recovery failing to flash

So I flash the stock rom on it without thinking and now it wont let me flash a recovery to the tablet threw fastboot or goomanager and it wont update throguh asus update but its booting fine and wont take any updates at all i need help being pointed in the right direction!

I flashed the wrong bootloader i think and how do i flash the correct bootloader without a recover?

in fastboot im getting the error: cannot load 'file name' :no error weather its cm or twrp it wont load it and i dont know what to do please help

First of all it would be important to know what bootloader you are actually on. You do not want to flash a recovery that is not compatible with your bootloader!
So boot into the bootloader with Volume Down and POWER and read the tiny script. From there select the Android with Volume Down and boot back to system with Volume Up.
And then please report in detail what you are trying to do in fastboot, which commands you use etc.
Without knowing what you are doing we cannot tell you what you are doing wrong.....
First step: In fastboot command: fastboot devices - Do you see the serial number of your tab?

So you are on an ICS bootloader with a JB rom... How the hell did you manage to do that?
You did not answer my question about fastboot. What you tried and what did not work.
But anyway, how I would proceed, just to get you back into safe territory, is to download the latest Asus firmware 10.6.1.14.10, unzip the downloaded file once and copy the resulting zip to the root of your internal SD.
Reboot, and hopefully the stock recovery will recognize the update file and flash you to JB 4.2.1 (which BTW is the latest version for our tabs - there never was, and probably never will be a 4.2.2). Flashing the stock firmware will replace the bootloader.
So from there you just have to get fastboot working, flash the latest TWRP and then the custom rom of your choice COMPATIBLE with your bootloader and recovery.
If that doesn't work we have to try something else. But try this first and report.

NEXUS 5 stuck at Google logo

Hi Guys,
After some cleanup in CMW i accidently format EVERYTHING. (formatted all single option in CMW, afterall a bad idea) So now i'm stuck at the google logo.
Now i have the 4.4.4 KTU.zip on my computer. Can i flash this via ADB sideload (as a renamed ''update.zip''? Or can i just copy the .zip file to my Nexus from a computer?
I'm @ work so i;m stuck guessing what i must do to get this thing work!
Thanks in advance guys

i dont know what it is, but if its a rom, sideload then flash away. your phine is empty right now, no rom or anything. you need to put something into your phone(sideload) then flash it.

Yes, the whole zip file is the stock ROM in a zip file.
Luckely i can't login as administrator here or else i could get my device working here
Thanks!

Why not just start the bootloader (fastboot mode) and execute the flash-all.bat? It'a the 'official' way to completely restore your phone. I've done it several times and it always worked great

Boot loop to recovery

Hello everyone,
I have accidentally messed up a TF700 device that my grandma received from a friend. Now I am stuck in a loop, when the device boots up directly into recovery. In recovery, I can connect with adb and reboot to bootloader with fastboot mode, where I see the three icons and I can connect with fastboot, I can even boot the stock ROM, which works fine now, because /data has been wiped.
I have been looking for recovery blob on Asus website, but it looks like Asus has totally cut off the device support, I can not find anything.
Because I have been doing lots of nasty things to the tablet, by following a guide for flashing the TF201 (long story including wrong model name on the device sticker ) the easiest solution is probably to flash the original recovery, bootloader and ROM. Does anyone has by accident the recovery blob for Bootloader 1.00e ww_epad-10.6.1.14.10-20130801 a03 ?
Or is there any other solution for the loop? The problem is that in the recovery, I can not do almost anything, no partition can be mounted, I have probably flashed recovery for TF201.
Thank you.

Yes, best would be if you reflash the Asus firmware, then start from scratch.
Geab the zip here https://www.androidfilehost.com/?fid=817550096634791660
Extract it until you see the system blob (called simply "blob"), move it to your fastboot directory and flash it in fastboot:
fastboot flash system blob
Reboot
That returns you to a stock system.
Then flash the latest TWRP, format /data, then flash your Katkiss rom of choice
Good luck

This is awesome, thank you for such quick reply. Just one more question, is it OK to flash US recovery if there is WW version bootloader? Just to be sure not to scew it even more

Yes, flash away. The bootloader is the same for WW and US, just some wifi modules are different, I think.
That firmware is US anyway and it includes the bootloader, so you'll have a US BL afterwards

Works fine for me. Downloaded it and it opened without problem. Try this link, uploaded the same file here: https://www.dropbox.com/s/tz1lcspqayhs7ug/US_epad-user-10.6.1.14.10.zip?dl=0

No I just can not extract it
7-zip, winrar, gzip tried and I always get CRC error. I can however open it to see what files are inside, but not extract the blob to flash it. So maybe there was a little misunderstanding.

So Good news (partially), I have managed to find on the Internet similar package with WW. Extracted the blob and flashed to system partition. But nothing has changed, it is still booting right to recovery (FlatLine CWM)
Strange thing is, in recovery, I can not mount any partition.
Another strange thing is that in the fastboot mode, there is no blue progress bar as it used to be before I damaged it. Also it does not respond to any reboot commands. I have to do hard reset.
Any idea to try out, please?

Mhhh, maybe you have to go the super clean route.
Run these commands one after the other, letting every single one finish. Some are very fast, some take a bit longer
fastboot erase misc
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase boot
fastboot erase userdata
fastboot flash system blob
fastboot reboot
If it hangs at any of the commands (30 min or more does not return to prompt) just reboot with the buttons and continue with the next command.
Good luck

Awesome, I have some progress here, thanks to you. After formating the other partitions, the fastboot screen finally started to react and the blue progressbar appeared and the blob has been flashed.
After that, I have rebooted the tablet and it was stuck on the ASUS splash screen. When I rebooted to fastboot again, and tried recovery, I got Dead Android image instead. So there was no recovery image on the partition. When I tried to select cold boot to Android, I gets stuck again. So I have at least flashed TWRP recovery back again and I can boot to that recovery.
Also it looks like, despite of what was the archive name, I have now US bootloader and not WW anymore
So how to ged rid of the ASUS splash screen now? I suspect there is no kernel and RAMdisk on the boot partition now, since I have formated it, right?
I have tried flashing the JB kernel linked in the thread here https://forum.xda-developers.com/showthread.php?t=1919961 but without any result. However I am not 100% sure about the android version.
Or maybe this is a good time to flash completely different ROM?

Ok, step-by-step...
Strange though that it did not boot after flashing the blob... hope you do not have something else going on.
The Asus blob contains everything: Every partition is reflashed with stock software so everything should be in place. The dead Android is the stock recovery showing that it cannot find anything to flash. That is perfectly normal and healthy.
Yes, do not try to piece the system together, flash a full rom now (after formatting /data in TWRP).

I would recommend one of the KatKiss roms, the latest is here:
https://forum.xda-developers.com/transformer-tf700/development/rom-t3457417

Hello and sorry for not replying long. The baby at home was sick so I didn't have time to play with the tablet.
I have flashed the ROM you linked and the tablet finally is booting and working :victory: Or so far it looks like that
Thank you so much for your asistance here, I learned a lot on this journey.

For whatever it is worth, I just had a sudden occurrence of a similar problem. Im still using this tablet on an almost daily basis and one day it started a boot loop. When I tried the RCK it would show TWRP and then bootloop again. Followed the 'simple clean' steps and reflashed twrp and clean version of KatKiss and now good to go! Thanks @berndblb for the refresher course in fastboot commands.....
