[Q] I seem to have soft-bricked my TF300. Ideas? - Transformer TF300T Q&A, Help & Troubleshooting

I was just in this thread, where someone fixed their soft brick: http://forum.xda-developers.com/showthread.php?p=37314263#post37314263
Mine stemmed from the same thing. Trying to flash a JB rom over ICS.
My TF300, when it boots up, only has options for fastboot and normal boot (AKA, stays on a white Asus logo). There's no way for me to get into a recovery, even though I had TWRP installed. I tried using NVflash, but there's no way to use it when your tablet is already soft bricked.
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
C:\Fastboot>fastboot -i 0x0B05 flash system blob
sending 'system' (799748 KB)... OKAY [144.648s]
writing 'system'... FAILED (remote: (InvalidSize))
It also has some weird issues in fastboot mode. the reboot command doesn't actually reboot the tablet, even though it says successful. Also, it'll only run one command at a time successfully before I start getting all sorts of errors in command prompt.
I have no idea where to start with this thing... Any suggestions?
edit: Also, wiping data from fastboot doesn't seem to do anything. It just freezes. Likewise, in fastboot, when I let it sit and it's supposed to reboot on its own, it doesn't.

Try this link for access to recovery or apx.

No luck. The tablet literally doesn't have a recovery at all. Trying to flash any stock ROM through fastboot results in failure.
Every time I try, command prompt gives me the error FAILED (remote: (InvalidSize)) and my tablet does the "Failed to process command flash:system error(0xa)" message
I'm not sure if any flashes through fastboot are even working right. It says success, but the reboot command never works (Even though that says success, too)

Have you tried reflashing your recovery then installing a stock rom from there?

No fastboot, no recovery, no apx backup
Sell it for parts

Etc
Or buy a new mobo

Yeah. No luck. It'll say success, but the tablet freezes and the reboot command doesn't work. After I manually reboot, no luck either.

I've looked up some information about it. People who experience the same problem (not able to get into recovery, adb, etc) had to send their tablet into Asus and it got shipped to Czech Republic, then in about 3 weeks it's returned ready to go. Maybe that's a possible route? If not, search xda-developers deeper and check out transformerforums. They have alot of stuff linked to XDA so who knows, maybe what you're looking for is on there.
Best of luck to you!

Which recovery do you flash
Jb or ics version
Cwm or twrp

dont waste more time
As i posted somewhere else, this tablet is a pretty bad purchase.
I bricked mine without unlocking bootloader, without flashing anything, without even connecting it to the computer.
One day it got stuck in asus screen.
After hard reset, recovery and wipe data i was left out with a brick. (no more snk, usb, wipe data screen)
Interesting you can brick a tablet without doing all those things they warn you not to do.
Dont waste more time looking for a solution. theres none, your tablet is now a useless brick.
sell it to someone who needs the parts.

Wow, that's really weird. Hard to believe that it just bricked itself one day. Since it was never unlocked, did you take advantage of the warranty and say it was a manufacture defect?

I had the same issue although it stemmed from a different origin. I'm guessing it won't reboot on its own because you've wiped the /system files. Can you still connect to your PC using fastboot? If yes, try the command "fastboot -w", then try fastbooting the stock ICS blob file. By the way, I'm still new to the Android platform but I've learned quite a bit in the last few weeks by tinkering with my two Android devices and soft-bricking them several times in the process.

I had the same problem, and my understanding is that it stems from a messed up bootloader. Literally, I had the -exact- same error messages so I know what you are going through.
Fortunately, I was able to use NVFlash to recover mine. I don't know what other solution there would for you, my friend. Best of luck, let us know what ASUS charges for the repairs if you decide to go that route.

[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

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.

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?

[Q] Brickety Brick

I couldn't leave well enough alone and I f'd up somehow trying to flash my pad to 4.2 stock from Cyanogen with TWRP. Now booting thru vol- and power brings up TWRP only. It asks me for a password, which it never has before. I hit cancel and it puts me into home screen. Only ray of hope I see is that ADB still recognizes it and interacts with it. I've tried pushing every ROM I can get my mitts on to the pad. When I try and install it fails after a few seconds. Then the files I just pushed are no longer on /sdcard. I don't have a clue.
Anyone, anyone? Bueller, Bueller...

Make sure you have flashed the correct version of TWRP. as there are three different versions on their website. If you are confident you have flashed correct TWRP version then you may need to downgrade to the previous version of TWRP. I had a similar issue I downgraded to 2.4.4.0 JB build. Hope this helps
"...you may need to downgrade to the previous version of TWRP."
I can't get into fastboot to install an earlier version. I think I'm screwed.
Theoretically I could use TWRP to totally wipe the pad and then ADB to push the system files back on, but... I don't have that kind of tech knowledge and I doubt anyone who doesn't work for ASUS does.
Edit: My mistake. You can use ADB to install TWRP. I'll give it a shot, though I'm pretty damn sure it's a long one.

I don't get three or four icons. It boots directly into TWRP. ADB still recognizes the pad and I can still push files to /sdcard. I tried reflashing the ROM but it fails after just a couple seconds, shuts down and boots back into TWRP.
I'm going to get a flashcard reader today and format my external card FAT32 and see if I can't install a new ROM from that.
im in a different situation
i did a erase system in fastboot
now i can only go to fastboot with preload on it
or
apx
is there any wait i can fix it and bring it back to live
Update: Bought a card reader at local Discount Electronics. Plugged it into my PC and it promptly froze my computer and destroyed my $80 64G sd card. Can't catch a break here. So I need to get another card and reader before I can attempt to install rom from external card.
The card reader is by a company called Zeikos. http://www.amazon.com/electronics/dp/B001T9N0R6 You have been warned.

You will have to reroot but with motochopper that is minor.
Unzip 10.6.1.15.3 till you have a blob file. Place the blob in the directory with fastboot.
Reboot into bootloader and wait for fastboot to start. (watch the upper left of the screen)
fastboot -i 0x0B05 flash system blob - wait for the flash to finish then
fastboot -i 0x0B05 reboot
Good Luck!

Reboot into the bootloader. If you get into the bootloader cold boot - volume down on the first icon.
If your tablet fails to boot into android go back to the bootloader and reboot into recovery.
I'll wait for your response.

From off state it always boots into TWRP. I stupidly installed an older version on accident. 2.2.2
With your help I was able to boot into fastboot with the adb command. I've run installs of both the ROM and tried an update to TWRP. According to the console everything went fine but when I give it the reboot command nothing happens. Somewhere in there it looses connections with the tablet it seems.

Excuse my noobishness.
I can get into bootloader with the adb reboot bootloader command you gave me
When I go to recovery, RCK right?, it freezes up.
From cold boot it goes directly into TWRP, which asks for a password which it hasn't ever before this mishap.
If I go to android from bootloader and it goes to TWRP as well

[Q] Locked or Unlocked?, boot loop, bricked.

Ok so I unlocked and rooted the my TF700 but had not yet installed any new roms or recovery on it, I was getting round to that but other things to do etc. So one day the battery ran out and when I powered it up bleary eyed one morning it said it could not boot due to being encrypted. I had not encrypted it. So the only option I had was to wipe the device.
Done so back with a working device for some weeks. Then the other day I powered it off. When I powered it back on boot-loop, gets to the point of Asus inspiring inovation persistent perfection (yeah right).
No problem I thinks I'll just use fastboot to save the day because when I boot it says "Device Unlocked" and I can get to the RCK/ANDROID/WIPE screen. So run fastboot and it says it writes to the device but I don't believe it as the copying of an image takes ~130seconds and the writing 0.094s.
So I think I am in this half-locked limbo and I am assuming there is no way out of this.
I've tried a stock rom on the sd card which gets up the Android with a spinning blue vector in his chest but this goes on for about 5 minutes and reboots again back to boot loop.
How did it get half unlocked and if its half unlocked then surely its not unlocked so how does that affect the warranty, I may just send it back and see what happens? I am annoyed because I had not got around to messing around with custom roms etc... I also thought it wouldnt OTA update I am guessing maybe this is what happened when it complained about the encrypted device.
I really am about to give up and use it for chopping onions, a very expensive chopping board.
Not sure if anyone has any bright ideas but I'm all out...

Ok so I unlocked and rooted the my TF700 but had not yet installed any new roms or recovery on it, I was getting round to that but other things to do etc. So one day the battery ran out and when I powered it up bleary eyed one morning it said it could not boot due to being encrypted. I had not encrypted it. So the only option I had was to wipe the device.

Sorry, from your description I don't quite get what exactly you did. What did you try to write with the fastboot command? To me your problem sounds like a bootloader problem.
I understand you still have fastboot access to your device? If so, I'd suggest to follow the steps described here at "Scenario Two":
1. Load a custom recovery, e.g. TWRP with the fastboot method.
2. Download the recovery + bootloader package as described in the CROMi-X thread.
3. Boot into recovery and flash that package.
If you get to this point you should be able to flash any custom (JB based ROM), recommend the CROMi-X.
Hope this helps!

ok, thanks for the clarification. However, that is exactly what I would have done ... you have checked the download file and fastboot seems to transfer it. From then on you should be able to boot into recovery.
Forgive me please for a dumb question ..but have you tried to boot the "classic" way? Like switching the device off and then power on with the Volume minus key pressed? Other than this, I am sorry but I don't have any further suggestion

Some things about your fastboot commands are very interesting..
First, what was the operating system that you were using. Second, your recovery name is not the same as you tried to fastboot with the command. Third, I think that you may do something incorrect with fastboot because your bootloader is fine and please be careful with your bootloader. If something is wrong with your bootloader, it is hard to bring it back unless you have your NVflash blobs... Last, you are still with the stock recovery and did not have a custom recovery installed yet.. Also, it seems that you have a bootloop. Any way, I think that you are still good depending on what you want to do with your device...

Linux, I renamed the recovery as per the instructions at the TWRP teamwin page (cant post links)
It seems that although it says the device is unlocked I cannot write anything to the device and it is stuck in a boot loop, wont flash the stock image from the sd card either. I have been searching for a solution now for a week and can't seem to find anything.

Your finished times are way too fast - mine are 10 times this so I suspect it hasn't written the recovery blob correctly. Did you notice it put a blue time bar on the screen when doing the write?

Yes I noticed that in comparison to other peoples output that it is too quick.
No there is no blue time bar put on the screen. After you fastboot the recovery the green block that pulses on the selected option RCK for example, stops pulsing and then I have to pinhole reset.
I am thinking that the unlock didn't correctly unlock the device orthe time it would not boot requiring a data wipe because it said the device was encrypted, I guess somehow it got an OTA although it shouldn't have received one. But I cant understand how the unlock could be reverted because the consensus is it cannot.
If the unlock didnt work I may try an RMA on the grounds that its not properly unlocked therefore the T&C for unlocking is not really valid as I would have expected to have an unlocked device.

I seriously doubt your arguments will get you anywhere with Asus since they don't support unlocking, but I've never heard of a "partial unlock". Either it works or it fails.
I suspect your problem is related to "bleary eyed", the encryption and data wipe you did. Or a driver issue on your PC.
If you cannot install a custom recovery via fastboot, I would try to flash the stock firmware and start at square 1.....

Did you turn on or tick the USB debugging in the developer options? You need to turn it on in order to fastboot... Good luck..:fingers-crossed:

Are you sure? The bootloader mounts the /data partition to read some Android setting? Does not look plausible to me.

Thats a good question, I would have thought so (always do for everything else) but now you mention it. I can't say for sure. And it won't accept the stock recovery from sd card, 5 minutes of spinning blue thing in chest then reboot into boot loop...

Thats the wierd thing, I did not encrypt the tablet, just discovered it with the green android telling me it needed to do a full data wipe because the tablet was encrypted, I've never encrypted any of my android devices. After this process it worked fine again. Then last time I powered it off it came back up in a boot loop.
I've put the stock firmware on an sd card and the it spins for a few minutes 3 or so then reboots into boot loop.

Well, I can kind of confirm this. Without having done scientific research, but recently I fought my fastboot connection as well. It turned functional only after I checked the USB debugging thing.

That was how I learned to fastboot. I never have problem with fastboot. I can do a test for you when I fastboot twrp 2.6.3.1 without usb debugging..

You are an expert in this area. Do you have any good advices for someone in need? Do you know why some users can not flash anything even though they follow the instructions closely? It would be nice if you can share your knowledge with new users like us...

The real experts in this area are those who brought you wheelie and flatline... for me it looks very confusing. The twrp.blob md5sum matches mine, and I don't understand why it finishes so fast, says "OKAY" but doesn't work. If there was a problem with the fastboot protocol or with writing to flash memory, I'd expect some error message. Anyway, maybe try a different/newer fastboot binary or another USB port or another PC? I assume it's Linux on the native machine and not a VM?
I've seen a bootloader which would not flash anything in the case where someone cross-flashed a TF300 bootloader on the TF700, but I assume the OP has never tried such a crazy thing. Check the bootloader version, it should be 10.6.1.14.x.

[Q] [Question] CWM Installation and brick ?

Hello there,
First of all, thank you for your answer and sorry for my bad English.
I own a Asus Infinity TF700T since one year now which worked on CyanogenMod until today.
I had installed CyanogenMod 10.1 with TWRP and decided to install version 11.
In order to do so, I put CWM 6.0.4.5 in my /download folder with CyanogenMod 11 and the GApps.
I then installed CWM through TWRP (I cant remember which version though...) using VolDown + Power and selecting RCK and tried to reboot.
But it did not work.
It is stuck on the Asus logo with the "device is unlocked" message in the top-left corner of the screen.
Cant even restart with the same old VolDown + Power. If it had worked once, if then went stuck on the same Asus logo, trying to start the recovery.
For now, my TF700T is so bricked. I cant do anything with it but looking at taht fancy Asus logo.
I dont even know if CWM is installed or not since I could not boot on any recovery.
Thank you for your help.

Nah, as I said, I cant boot using VolDown + Power and so cant reach the RCK screen.
:/
I did install the APX drivers and my TF700 is fully recognized in Windows.
I am now trying to fastboot through Windows in order to get this mess cleaned but it seems compromise.
Moreover, I did not previously back up my NVFlash...
It seems I'm in it, huh.

This is the ONLY solution for this problem, worked great for me.
My solution
I have the same on my TF300t and A700 - but it seems i just managed to get my TF300t back
i tried all fastboot (reflashing recovery, boot, system etc) no dice - especially since writing system was done after 3 secs all the time.
Here how i restored my TF300T JB
download your appropriate lates firmware from Asus (WW, US etc.) and extract the zip twice so you have your blob file
install your device drivers if needed (i used Google SDK ones) (and as a Tip Win8 sucks for Fastboot stuff so try to get Win7 Vista XP for this)
Reset your device with a paperclip/needle (about 2 cm down of your sdcard slot) and hold vol-down to enter fastboot
(the folowing i did at least 10 times already but didn't erase misc)
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system c:\adb\TF300t\blob (this is my path - your's may vary depending where you stored your blob) ((also this was the first time i saw the loading bar while flashing)*
fastboot -i 0x0B05 reboot
* it also took a lot longer as it should:
C:\>fastboot -i 0x0B05 flash system c:\adb\TF300t\blob
erasing 'system'...
OKAY [ 1.695s]
sending 'system' (800935 KB)...
OKAY [133.121s]
writing 'system'...
OKAY [153.973s]
finished. total time: 288.789s
im now setting my tab up to get back to CM (which initially caused this sh1theap due to autoupdate error, same as my A700 got bricked )
hope i could help you out!

Hey kansasboy, thank you for your help !
I cant enter in Fastboot mode, even when using the Reset button + VolDown.
All I see is my TF700T correctly detected in my Windows 8 "Devices". It is in APX.
Anyway, I'll try your trick and hope it will work.
I'll stay in touch.

I think you have hard bricked if you can only get to APX mode and you don't have NVflash backups from your device.
Sorry
Your only choice is to replace the mother board, either from Asus or yourself.
I have the same issue.
I'm able to access the tablet through adb and run commands. Can you do that?

You have adb but no fastboot????
Try
Code:
adb reboot bootloader
That should boot you into the bootloader and then you can try buster's method to get it back.
It was one of the first things that I tried. Unfortunately the console seems to hang.
I'll try to leave the console opened after it hangs - hopefully it will reboot at some point.
I also tried to dd the twrp blob into mmcblk0p4 but it has the same effect - it hangs.
In case anyone wants an update to what I was saying in the posts above.
I managed to dd the twrp blob into mmcblk0p4. Apparently it takes A LOT to flash it.

Hey,
Sorry for the time not answering.
I only got APX on my TF700T, in any case I could reach ADB.
For now, the tablet is in the after-sale service of my seller, here in France.

Nvidia Shield Tablet OEM Unlock

Ive scoured the web for the solution to this but for the life of me can not get my boot loader to unlock. I know enough of this to get me by, but obviously I am not an expert by any means. This is one of the pre recall tablets that I had rooted to avoid the kill code. It was so long ago when I did this that I don't completely remember how I did it. But apparently I didn't have to unlock the bootloader to root it.
I haven't used this tablet in ages and decided to pick it up again but was getting errors that I needed to update google play services but it was not allowing me to do so. I have the Custom Rom Blisspop installed but it appears that they have quite support for it. So I was going to wipe that off and load Lineage. so I tried to get into recovery and it kept just stalling at the loading screen. So now I am wondering if I even flashed a recovery to it to make a backup. Regardless I wouldn't want to restore and risk getting the kill code delivered.
So the next thing I tried to do was flash twrp (and yes I did use the NVidia shield tablet version) and it said that it was successful but still could not boot into recovery. Then I noticed that it said my bootloader was locked on the bootloader screen. So I installed the platform tools and the drivers and adb was recognizing my tablet and everything was good. Until.... I did "adb reboot bootloader" and then "fastboot devices" or even "fastboot oem unlock" nothing worked. No devices would show up. But this whole time adb works. No matter what drivers I install or anything, I cannot get fastboot to recognize the device. I even changed the USB port to the back of my pc straight off the mobo and ran the cmd as admin and nothing is working.
I am starting to get discourage that my efforts are going to be for naught. Expecially since I am not sure exactly how I rooted it in the first place? which is completely my fault for not documenting it. Any and all help is greatly appreciate and I apologize if this has already been solved else were or is being posted to an incorrect location.
Thank you!

Ok, i finally figured out that the fastboot driver wasnt working. I ran "adb reboot bootloader" and while in fastboot mode, i found in the PC's device manager that there was an error with the driver. I manually updated it and i am finally able to successfully run "fastboot oem unlock".
But now im getting an error with it saying it failed....
Code:
C:\WINDOWS\system32>fastboot oem unlock
...
FAILED (command write failed (No error))
finished. total time: 0.002s
I am unsure what this means and will do some more researching. I will post back if i make any headway. Once again, i thank anyone in advance for any assistance they may be able to provide.
Apparently i had to unplug the tablet after installing the driver for fastboot before "fastboot oem unlock" would work. But it now says "Device = unlocked"!!!! hopefully i dont mess anything else up...
So now the tablet is "unlocked". I went to do "fastboot flash recovery twrp.img" and said it succeeded. I then proceeded to to do "fastboot reboot" and read that you should immediately load back into bootloader because some tablets will overwrite the recovery to stock if twrp isnt given a chance to correct this. So i did just that then volume keyed down to recovery and its back to doing the same thing where i am stuck on the nvidia logo loading screen. Does anyone have any suggestions on a fix for this? It appears that the tablet is refusing to enter recovery mode?
The reason why i need to get into recovery is for A: to make a backup. and B: to clear my current blisspop rom so that i can load a different Rom. I doubt it would be a good idea to install an OS on top of another OS. But who knows, maybe thats fine?

Once again, I thank you for the help.
I was up all hours of the no ight last night trying to solve this with no luck. Is there anyone here who might be able to help me?
Still can't get recovery to load... Tried everything. I did "fastboot - w", I tried flashing lineage on top of bliss pop. Nothing I do will give me access to recovery...
Any ideas?
You have to use hardware keys combination (power + volume + or - not sure exactly which) to boot to twrp for the first time after flashing. So hold the combination while you're still in fastboot (bootloader) mode and release when you see nvidia logo. Good luck
Edit : fastboot reboot is a command that takes you to system, not recovery, to reboot to recovery by using commands you habe to type fastboot reboot recovery. But still, I believe you have to enter for the first time using the buttons combination but it may work with fastboot reboot recovery
It's possible the bootloader is too old for the current twrp release to boot. Which version of android is on the tablet? If it's like L, then you'll have to either update the bootloader manually or update stock first, then twrp will work. There's a note about this on the twrp device page.
