[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

Fastboot TWRP or CWM recovery, format everything in there and flash ex. cleanrom 2.5
Let me know if it won't work

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

This tablet is such a fiesty little *****... Nowhere near as simple as my GNex to flash things.
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?

This is an awesome fix, thought I was buggered with a tablet that couldnt mount anything, couldn't get into download mode, recovery was fubared.. and then I stumbled on this
THANK YOU

[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...

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!

Then if I leave it, it boot loops again.
If I hold volume down I get back to the RCK/Android/WipeData fastboot screen. If I try RCK I just get an android lying on its back. If I try from the sd card it spins for ~5 mins then reboots and back to boot loop.
So its almost as if its not writing anything with fastboot.

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..
Edit: @_that
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.

Indeed. Seemed like a good idea at the time. Fed up with this rubbish now, gpl'd but still managing trying to foist essentially drm on it. I think what annoys me most is the insidious and slow corruption of the ideal. Must say its partly my own fault, i have stood by and done nothing.
Apologies anyway.
Think I'll buy a Rasberry Pi.

boorloader woes jb4.2.1

Hi
Having problems flashing from stock TF300T JB4.2.1
I started by downloading the asus bootloader unlocker.
Im not sure if the bootloader unlocker wored properly or not.
Then I reboot tablet using Vol DN + PWR
I boot into a bootloader and it says starting fastboot usb downloading protocol
I have 3x icon choices
[RCk] ... [Android] ... [WipeData]
There is no USB mode.
According to the guides I have to select usb mode.
What has gone wrong?
Thanks
Mike

in 4.2.1 bootloader menu usb mode (fastboot access) is enablet by default, when you are in this menu, just use command fastboot devices and check if device is visible.

Make sure the guide and ROM you are installing is for your bootloader and not the previous version.

I got this error early on on a different PC than I use now. It turned out to be the USB port on my PC that I was using. I moved from a front port to one on the motherboard in the back and it flashed successfully. I know others have had cables that caused the error so try a different cable as well.

Error related to the bootloader not being unlocked, i have gotten a bit further now.
I now can run TWRP recovery, so I'm doing a full backup to internal storage.
I guess after that I should copy that onto my PC.
What is the next step after that, is it safe to now start flashing roms.
If I flash a 4.3 or 4.4 rom, can I go back to 4.2?

Glad you solved the problem. :good:
Making a TWRP backup is good but I suggest making a Flatline - NVFlash backup to be sure you have a way back if you brick your tablet. It is time consuming but well worth the effort. Here is a link to that procedure - http://forum.xda-developers.com/showthread.php?t=2455922.
Several considerations before you flash a custom ROM. Be sure you have the correct bootloader and recovery version for the ROM you are flashing. As far as returning to 4.2 after moving to 4.4 I believe there are a couple of ways but haven't done that myself.
All of the threads with custom ROM's have very clear prerequisites and steps to follow for each particular scenario. Also, there are hundreds of posts in the Q&A and Development forums with excellent advice and cautions. DO YOUR RESEARCH! I know from experience that rushing into it can be a disaster and without having a thorough understanding of the steps involved and the potential pitfalls, you will wind up with a bricked device. I bricked a smart phone about a year ago just because I didn't take the time to do the research. It's a hard lesson to learn that way so take the time to research, research, research, especially if you are going to try different versions and different ROM's. In the end it will be time well spent.
Good luck my friend!

Bricked XT925

Hi all, first post here.
I have a bricked XT925 which I'm trying to recover.
It will go into fastboot and I can access it with ADB/Fastboot/mFastbootv2/RazorHDToolkit5.0/RSD lite etc, but none of these will write a new recovery to flash.
I was able to unlock the bootloader using the Motorola website and the phone will talk to the PC software, but it's as though the internal flash memory is trashed.
In fact lots of commands to the flash result in a "fastboot max download size 30mb" error.
Can anyone help?

I would start with obtaining a clean working flash of the official ROM, before trying to flash anything custom.
Just a guess, but if you went to the unlock website after the phone was soft-bricked, the bootloader may still be locked. I assume that the phone needs a full working OS to receive and implement the unlock signal from Motorola. Since it hasn't booted the OS since it was bricked, it hasn't had a chance to do so.

Would that I could. All the links I've found so far are dead.
I have another XT925 in working order, anyone know how to extract the image from it?

I think the Bootloader error messages are to be expected, everything I've since read suggests I should ignore them.

I have one of the old Canadian leaked KK stock sbf (I was using it to see if I could bring anything to my AHD). I can post it to my GDrive and post the link this afternoon.

Thanks for that, unfortunately my situation has become worse.
Whilst the phone was connected and in fastboot mode, I deleted the ADB driver in Device Manager and now the PC, or more specifically ADB and Fastboot wont talk to the phone. Grrrrr.
Oh, and the other handset has decided to die as well.
One thing at a time. Anyone know how to restore the driver/get-the-phone-talking-to-ADB/Fastboot again?

Fastboot FAILED (remote: failed to erase partition )

I have OPO 64GB and unlocked via fastboot. Every fastboot command related to flash or erase or format gave same error, unable to erase or write the partition.
I was able to fastboot boot <custom_recovery.img> into TWRP 2.7 I believe but TWRP gives errors, unable to mount <partition>, etc. Any command in TWRP results into a failure to mount or write.
I tried ADB Sideload <zip> and at 12% it rebooted back into Cyanogen Mod ready logo.
TWRP only runs if I boot to it via fastboot, it can't write to the bootloader via fastboot. One strange thing under TWRP storage it shows Internal Storage 0MB and USB-OTG 0MB, the partitions also show 0MB excep for system, but can't format anything or resize.
I feels like there is no storage in this device, is this something that can be fixed or is this a DOA device? It was working fine and a Cyanogen update ran and bricked it!
When I try to fastboot flash I get this error, fail to write. I even tried the OnePlusRestoreTool and it fails to write to the phone.

It seems that your partitions are corrupt.
I had the same issue and solved it by restoreing completley to stock Rom. There must be a thread for this anywhere out, if not download a fastboot image from cyanogen support site extract it and try to flash it.

That is what I was leaning towards, but in every solution to restore the stock ROM I have to use fastboot and fastboot just fails to write anything. I can't even get TWRP to stick, fails to write every time. I tried the OnePlusRestoreTool but the driver installs ok but the tool can't find the phone, tried 2 different PCs. I was hoping for another solution other than fastboot or the OnePlusRestoreTool, I searched but could not find another method, I was hoping someone could point me in the right direction.
Thanks

So I tried the link but also their method uses FastBoot and FastBoot fails to write to the OPO every time no matter what, see below. I can put TWRP in memory but can't write to the SD I guess. Any tool that can reformat the storage and put it back together since FastBoot and ADB can't write to it?
Thx

Try this http://forum.xda-developers.com/oneplus-one/general/guide-unbrick-oneplus-one-t3013732 , it will rewrite all the partition and then change the rom and recovery you want, it should work

Hello, so I managed to get an older PC to do all this in as well and tried another PC anyway. I ran the color.zip install, drivers installed OK and phone is detected, I ran the Msm8974DownloadTool.exe and it found the phone in COM3, I see a progress bar in one file, the image file and then it reboots the phone but it comes back to the Cyanogen splash screen and it does not go anywhere, so I reboot it again manually power+VUp and the tool finds it again and tries to send the *same* file again, and then I tried this loop at least 10 times.
I conclude that it is unable to write the image to the cell, same symptom I encountered with Fastboot flash boot img. Does this mean that the cell is bricked since nothing can write to the SD?

Do the progressbars you see in Msm8974DownloadTool.exe become green?
Maybe see there:
http://www.technobuzz.net/guide-to-recover-from-hard-bricked-oneplus-one/
It is nearly the same like the one posted before, but has some screenshots.
After doing this color OS should boot up, not cyanogen os.
If only one image file is "flashed", check if your color.zip is downloaded correctly
Hope this helps

Hello, not really, it does one file and then I see progress bar move on the first file, progress bar finished and then the phone boots to the cyanogen screen again, then i tried again, it still shows the same file again. It does not save the file, fails to write pretty much, same thing as fastboot.

There should be serveral progressbars. One for each image in color.zip. Try to reinstall the qualcomm 2012 drivers.
Have you restarted your PC?

I actually did that and tried one plus one as well, I also tried the other unbrick toll as well with other drivers. The phone is recognized no problem, but nothing can write to it, just like fastbook flash , write denied every time.

Restarted your PC after qualcomm driver install?
Maybe there be driver problems related to win10.
Also check
fastboot oem device-info if your bootloader is really unlocked

It won't work, his device is not recognized by adb or fastboot.
My device is in the same state, I rebooted it and it hard bricked, I tried using the ColorOS flash tool but, when I start it, it is stuck in a loop trying to flash "8974_msimage.mbn", any solution would be appreciated, because I hard bricked it in the first day after receiving my OPO (I bought an used one).
I already tried on two different computers, the same issue happens, I also tried to find a fix, but everyone that had this issue never replied, so I think this state is really THE hard brick, with no ways to go back to the original state.
@newpop1_android did you find a solution for your problem?

The problem is that the device gets disconnected when flashing for some reason. I tried two different drivers, both didn't work.
I'm willing to pay 5$ to someone who can fix this issue for me.

Which Windows Version do you use? I would try with win7. With win 8.1 and 10 you have to disable driver verification.
Have you disabled your antivirus?
Have you disabled UAC?
Maybe another USB cable?

Windows 7, but Windows 7 also needs to disable driver verification.
I don't use any antivirus.
No, but I ran the tool as administrator.
I already tried that, I tried with the original cable that came with the device and my Moto G 2014 cable, same issue on both.
It isn't a missing driver issue tho, Qualcomm drivers are installed and working because the ColorOS flash tool detects the device.
Anyway, thanks for helping
