[Asus Transformer TF700] TitanUranus:
Thank you, thank you all - I've got my tablet up and running again! Despite the stress, I managed to remain reasonably confident it could be recovered, purely because of good people like yourselves helping. Now I have the tablet up and running again, and I also have a sense of achievement in recovering from what was certainly a catastrophic failure. I can also say, I am immensley indebted to those who provided the instructions on using NVFlash to get those precious system specific files backed up in the first place. If something like this happens to me again (which I sincerely hope is doesn't) I'll at least have them to fall back on.

The problem was most likely caused by my microSD card failing at the wrong moment. When I went to reinstall the card was badly corrupted, though this could have been caused by the whole system having been corrupted, I think it's most likely the card failed during a restore which caused the problem.

I do have one question, when I go to recovery menu, where it says the device is unlocked there is a message "Key driver not found... booting OS". I don't remember seeing this before, does anyone have an idea what is is and what it means? I managed to restore a CM10.1 backup I had on another microSD, and also was running the latest Asus firmware, so clearly it isn't preventing me from using the tablet, I'm just curious - perhaps it ws there all along and I never noticed. When I first saw the "Key driver..." message, as I was trying to recover the tablet it really freaked me out more than anything else. I thought maybe there was an error with my NVFlash backup files and may be permenantly locked out.

I'm going to make a little pack of the files I used to recover, including the extracted files from the Asus firmware blob, that way I shall have it saved for an emergency. What I may do is write a little guide, and upload a package with all the required files with the exception of the device specific files. I have thought about making a windows *.bat file to automate the restore, but that's probably a bad idea, and I'd urge people NOT to attempt restoring the tablet this way unless it is the last resort. If I do write a little guide, it won't be in the next couple of days - I've spent enough time trying to restore my tablet to working order and want to enjoy using it a little first!

Again, huge thanks to all of you for taking an intetrest and helping me recover my TF700. If any of you need someone to test any new things on the TF700 I'd be happy to help any way I can, just let me know. If anyone is unfortunate enough to find themselves in a similar predicament please feel free to PM me and I'll help if I can.

I did it! I would like to thank Woot for selling me a new 700t for $369 while still running .26 bootloader. To everyone here especially those with problems as I read them all, and to those who offered solutions. Now it's on to the fun stuff:).

Sent from my AnthraXed AxisM Galaxy S3.
[Asus Transformer TF700] 33colburn:
I am in need of assistance please.

[/B]:crying: I have been trying to restore my tf700t to working condition. I need someone to hold my hand as it seems like I should be able to fix the but am just missing something. I have access to FASTBOOT. My computer recognizes the tf700t when in FASTBOOT. The computer also recognizes the tf700t in APX mode. I have typed in some fastboot commands and they work. Here is pertinent data if photos are not clear enough.

When booting to FASTBOOT screen says: Key driver not found.. Booting OS

Android cardhu-user booloader {1,00e} released by "US_epad-10.6.1.14.4-20130329" A03

Starting Fastboot USB download process

I am attaching 4 pictures to show what is happening. I tried the "10.6.1.14.4 US Bootloader and TWRP 2.5 DOWNLOAD " from sbdags, extracted the blob then used the following command in fastboot:

fastboot flash bootloader blob.SOS

and

fastboot flash bootloader blob.EBT

It says "waiting for device" then nothing.

I need to know if I can recover or am waisting time and need to send it to ASUS for repair.

Bootloader is unlocked.

When hitting the Volume + key with the RCK Icon highlighted I get this:

Key driver not found.. Booting OS

Android cardhu-user booloader {1,00e} released by "US_epad-10.6.1.14.4-20130329" A03

Unrecoverable bootloader error {0x00000000}

Thank you for any help in advance. I use this tablet from bed (just had a spinal fusion, 6 month recovery) and without it I can't do anything. Doctors orders to stay in bed for the first 4 weeks.

The problem happened when I used wiping script "JB.Format_ALL_X2.zip) followed by using TWRP 2.5 to wipe all partitions and then wiped Data partition. Upon reboot I received the Previous Screen information listed about.:crying:
[Asus Transformer TF700] TitanUranus:
First, sorry to hear about your health. I know what a blessing it is to have access to a computer - it really is an essential tether to the outside world for people like yourself, so let's get that damn thing up and running again!

The good news is, if you are still able to access fastboot, it's not going to be too hard to fix it. The bad news is, I'm not an expert, though I maybe can help you sort it out. Most important thing is that you don't worry too much about the TF700, there's lots of clever people here who will help you get it running in no time - just hang on. For now, you might want to try the following - if you have access to a windows PC.

download this:

http://www.androidfilehost.com/?fid=22901594685178272

Extract the download into a directory on your desktop (or somewhere else if you prefer). Then simply connect the TF700 to your PC and go to fastboot mode, open the folder with the files you extracted, and double click the file called "Scott's TF700T Recovery Install Tool.bat".

Hopefully this will get your recovery (TWRP) working again, and you can either install a fresh ROM of your choice, or restore a backup if you have one. Don't stress if this doesn't work, we'll throw some more ideas at it later and something will work eventually! Hope that does fix it for you though, good luck. I'll check back later (sorry, have to go away for a few hours, but will check back when I get a chance) and see how it's going.
[Asus Transformer TF700] 33colburn:
1st attempt no go. Ideas?

I tried it and this is what I got. See pics. Ideas?:crying:
[Asus Transformer TF700] TitanUranus:
It seems like you might need to install the drivers for connecting to fastboot. You can download the drivers and get some more information here:

http://xdaforums.com/showthread.php?t=1426502

Once the drivers are installed hopefully your PC will be able to communicate with the TF700. Make sure you install the correct driver, there are drivers for APX mode included in the package, but please DON'T try using APX unless you know you have the NVFlash backup files. APX could make things worse. Install the drivers, connect to fastboot and try running that recovery install program again.

As long as you are able to get into fastboot, things can be sorted out. I know how frustrating it is when you can't get things to work, but it will get sorted out eventually so try not to worry too much. It took me 2 days to get mine working again, but it was in a lot worse state than your TF700.

EDIT: SORRY, USE THESE DRIVERS!

http://androidroot.mobi/download/Universal_Naked_Driver_0.7_tf700.zip

The information on the link above is still useful though, just these are the patched drivers for the TF700.
[Asus Transformer TF700] 33colburn:
will give it a shot right no2.

Ok. I will try it.:good::fingers-crossed:
[Asus Transformer TF700] 33colburn:
Ok tried it. One time it said it worked and one time i got this picture. What do you think?:( But It still says no recovery kernel unrecoverable bootloader error 0x00000000
[Asus Transformer TF700] TitanUranus:
Hmm, I got the unrecoverable bootloader error too. Did you try the patched TF700 drivers from my last post? I updated it when I realised the link with the instructions didn't have the patched drivers.

If you already tried that, then I think it's probably better to wait till someone more knowledgable than myself can suggest something. Sorry I can't help you more at the moment. I have to go to bed now, but I'll come back and check how things are going tomorrow. Hope you get it sorted before then.
[Asus Transformer TF700] 33colburn:
I think I need to wipe the internal partitions or flash a kernel?

Maybe I need a big hammer. That weird one (picture) saying too many links. What does that mean? Does the recovery come with a recovery kernel? I have a feeling I need to wipe the partitions or repartition and try your steps again. What do you think? :confused:

---------- Post added at 07:00 PM ---------- Previous post was at 06:56 PM ----------

I have tried several drivers. Is there a way to make sure all other drivers are deleted. Well I won't send it in as no need to shell out 200 I don't have if the tablet can be repaired with some trial and error and patience. :good:
[Asus Transformer TF700] TitanUranus:
Sorry no one has been able to suggest anything yet. I think you will need to use fastboot to write a complete Asus firmware to the device, maybe write directly to several of the partitions. Not sure if this would require de-blobing beforehand or not. If you could do that and reboot the device, it would probably rebuild it from scratch. If no one else is able to help, I'll do a bit of research on how you'd go about this, but I'm a bit busy right now.

I don't suppose you managed to backup your original files with NVFlash when you got it? If you have, I could talk you through restoring the device with those files. Like I say though, the device should be fixable without having to send it away. If you're still stuck I should be able to figure out something for you over the weekend.
[Asus Transformer TF700] 33colburn:
Ok. I am moderately familiar with fastboot, and deblobing.

I will wait for your help. You are greatly appreciated. Since you think we can figure it out, I will be patient. I don't want to spend the money to send to Asus, since I'm currently disabled and would rather spend my assistance on my kids. Let me know what you find out. I have subscribed to this thread and eagerly await any email notification. Thank you Again for your time and effort.

Cole

If you think you could walk me through it I could use Skype to have you walk me through it. I had to break out my old tf101. Would be willing to makea small donation for the help getting it up and running. Sure miss having a keyboard :o
[Asus Transformer TF700] smalis:
If you have NVFlash capability, look at my posts 301 and 311. Those should enable you to recover your tablet.
[Asus Transformer TF700] TitanUranus:
No donation necessary, I just hope we can get your TF700 working again. It would be a real shame for anyone to have to spend money fixing something if it can be fixed for free with a little research and messing about. I think Asus just use these kind of problems to rake in some easy money from customers they should be trying to assist, not rip-off.

If you did back up your device using NVFlash and have those files safe, let me know as we can skip forward and fix it with APX. If you don't have those files, then I want to figure out how to write partitions using fastboot and test the procedure on my TF700 to make sure I know how it works and that it won't do anything bad (I have the NVFlash backups so it's safe enough for me to try things first).

I don't think it will be too difficult, but I want to make sure I don't give wrong information since I'm not an expert! With luck someone who knows how to do this will explain it in the next day or 2, if not I'll try it out on mine over the weekend and see how it goes. When my TF700 stopped working I couldn't even get fastboot to work, that's why I skipped over all that info and went straight to APX, but unless you have the original files for your TF700 backed up, using APX is not a good idea (except as a very last resort). It might just be as simple as writing the system blob to the system partition using fastboot then restarting, but I don't know how to do that right now. I'll get back to you when I figure it out (probably won't be tomorrow, I'm afraid I'm very busy).
[Asus Transformer TF700] 33colburn:
I was dumb and didn't make any nvflash backup as I was in a hurry. Too excited. To us

No nvflash. Will wait for more help. I will also review the other post suggestion above yours, but i may have tried it. I will get back with you later after trying it again.
[Asus Transformer TF700] 33colburn:
I think I can do it if you could help me with this error.

This is the error i get: See attachment. Everything else is ready to go

****PLEASE DELETE DUPLICATE****
[Asus Transformer TF700] smalis:
So you extracted the blobs from the stock rom zip and put them in the same folder as wheelie.exe?
[Asus Transformer TF700] 33colburn:
Here is what I think.

I can only find one official download from Asus. When I unblob it extracts giving me 5 files. All are named blob but with different extensions. The extensions are EBT, LNX, SOS, PT and APP. All are in the sMe directory. If I can get wheelie to work I think I can fix it. Ideas?

---------- Post added at 04:37 PM ---------- Previous post was at 04:26 PM ----------

I cant find the firmware for the bootloader i currently have. I can only find firmware 10.4.4.25. My current booloader is 10.6.1.14.4 maybe i need that firmware but i can find it. Asus doesn't have it on their site. Can you provide the stock urooted official version for me or a link. Don't know if that is the problem?

---------- Post added at 04:41 PM ---------- Previous post was at 04:37 PM ----------

Unblobing it gives me 5 blob files with the following extensions: EBT. SOS. LNX. PT. APP. Everything is in the same directory. My pc is vista 3bit and i run as administrator from the command line.

[Asus Transformer TF700] dragon57:
The original post in this thread says "THIS ONLY WORKS IF YOU HAVE A PRE 9.4.5.30 BOOTLOADER". If your bootloader is version 10.6.1.14.4, this will not work.
[Asus Transformer TF700] 33colburn:
That is what I was thinking.

But if I could get this blob.bin file i have had it flash a few things using fastboot. Hopefully someone can figure this out. I think this can still be done. Don't have any nvflash backups.
[Asus Transformer TF700] _that:
The only way to get the blob.bin for wheelie is by flashing the hacked bootloader over the stock 9.4.5.26 or earlier bootloader. If you don't have this file, you are in the wrong thread.
[Asus Transformer TF700] TitanUranus:
Did you get the PM I sent you? Basically I said try this, but with the TTF700 Asus rom instead of the TF300:

1. Power off your tablet

2. Download the latest TF300T firmware (XX_epaduser_10_4_2_9_UpdateLauncher.zip) from Asus site based on your SKU location (eg. ww, US, etc): http://support.asus.com/Download.asp...300T&p=20&s=16

3. Right click and extract the downloaded .ZIP file (XX_epaduser_10_4_2_9_UpdateLauncher.zip) onto your desktop

4. Right click and extract the new .ZIP file (XX_epad-user-10.4.2.9.zip) onto your desktop; you should now have the blob binary and META-INF folder on your desktop

5. Copy the blob binary to your platform-tools folder (C:\Program Files\Android\android-sdk\platform-tools or C:\Program Files (x86)\Android\android-sdk\platform-tools)

6. Plug tablet into your computer

7. Boot your tablet into Fastboot by pressing and holding Volume Down AND Power for 5 seconds

8. A message will inform you that you have 5 seconds to enter Recovery; press Volume Down twice to select Fastboot and then Volume Up before the 5 seconds expire

9. Open a command prompt and cd into your platform-tools folder; or press right-Shift on your keyboard and right-click the platform-tools folder and click "Open command window here"

10. Enter the following command in the command prompt: "fastboot -i 0x0B05 flash system blob" (without the " ")

11. Once the previous command completes enter: "fastboot -i 0x0B05 reboot" (without the " ")

I'm not sure if my PM's are getting through, if so can you please communicate through them for now.
[Asus Transformer TF700] 33colburn:
Could you point me in the right direction?

Thank you for replying. If you wouldn't mind pointing me in the right direction or are you saying it needs to go to Asus because my bootloader is to new?

Thank you,

Cole

Can't always get back with people quickly. Had a spinal fusion 3 weeks ago am in bed for the next few weeks. I would like to fix this rather than shelling out the money. Am currently on disability and would rather have the money for my 2 kids.

Thanks again.
[Asus Transformer TF700] 33colburn:
What about a clockworkmod backup.

Is there a way to use fastboot to push a backup I made when everything was working?

Thanks in Advance.

Cole
[Asus Transformer TF700] _that:
You need to get the TWRP blob from their homepage and flash it via fastboot. The command should be similar to:

fastboot flash recovery whatever-your-twrp-is-named.blob
[Asus Transformer TF700] 33colburn:
Thank you. I will try that.

I think I have done this already but will try again. But when I type fastboot reboot it doesn't reboot. When I manually reboot it doesn't stick or change anything. I still get the unrecoverable bootloader error 0x00000000 typed in red. So many things will flash I feel like with the wealth of knowledge you and TitanUranus have I can get this. I will try it in about 1/2 hour and post back.

Cole
[Asus Transformer TF700] 33colburn:
Ok here is what I have. See Attachments.

When I type in fastboot flash recovery twrp.blob it says waiting for device. Nothing happens even if I reboot to fastboot a second time.

When I type in fastboot -i 0x0B05 flash recovery twrp.blob it says it was successfull but upon reboot, same thing

unrecoverable bootloader error {0x00000000}

I think I have to get that wheelie program to get it running. The kernel is not getting flashed. I am wondering if the previous posted was right about my bootloader being to new. Maybe someone knows a workaround.:crying:
[Asus Transformer TF700] _that:
I remember some other people having trouble with fastboot saying "OKAY" but it still didn't work, but AFAIK nobody posted a success story - use the search function. You could also try flashing the whole firmware blob extracted from the Asus firmware download or from some incremental dlpkgfile.

No chance without the blob file (note that it is a completely different one as in the firmware). Since parts in that blob must be encrypted with a device-specific key, you can't use someone else's file.
[Asus Transformer TF700] 33colburn:
What to do now?

I have tinkered around with the fastboot and retrieved the cpu id number. Don't know if that will mean anything. Should I just send it to Asus? Would i be able to retrieve and then create what I need from a TWRP backup I made a day or two before it bricked. If i can could you point me in the right direction. Don't want to waste too much time if it just needs to be sent in for repair.

Thank you for your time and effort.

Cole
[Asus Transformer TF700] 33colburn:
I gave up and the place I bought it didn't mind returning it.

So as to not waste anymore of anyone's time, I wanted to say thank you for all your help and yes, I did make nvflash backups of everyining:good:

It seems that jelly bean requires the version 10 bootloaders. Just for knowledge sake I still wonder if it could have been fixed by somehow using a TWRP backup to recreate needed files.

Another question I have is: since I backed up using nvflash could I downgrade the bootloader? Or, does it not matter, you can't because of the updated bootload. BTW the new one is running nice. It was hard to go back to the TF101 and no keyboard for even a week.

Thank you,

Cole
[Asus Transformer TF700] usern ameisval idandnot:
Any chance to get this for the newest bootloader?
[Asus Transformer TF700] Pretoriano80:
I wouldn't hold my breath on that, this has been asked many times and the answer was always NO.
[Asus Transformer TF700] usern ameisval idandnot:
Could someone sue Asus for not giving you full access to a device they dont own anymore? If Mercedes sold me a car and would provide access to the trunk only after I agreed to lose my warranty that would be outrageous. Asus does that and on top they wont give you the key to the spare tire. :silly:
[Asus Transformer TF700] _that:
Try asking them for the firmware for the engine control unit - or even only for the onboard navigation/entertainment device.
[Asus Transformer TF700] usern ameisval idandnot:
So you concur with Asus? In the brick thread you sounded a bit different.I would not need the things you mentioned to repair my not moving car.
[Asus Transformer TF700] _that:
No, I still think they should give me my SBK for waiving my warranty. But a car analogy doesn't help. :)
[Asus Transformer TF700] usern ameisval idandnot:
Of course it helps. There are a lot of people with little knowledge that need an analogy to understand what digital companies do. Knowledge is power. Fight for your rights internet generation!
[Asus Transformer TF700] sbdags:
Yes but you are supposed to have access to the trunk. As _that says you are not supposed to have access to flash the ECU as you could render the whole car useless by doing so and why would they want to support that?

Their business case makes perfect sense. Users will and have bricked their devices through flashing. It is an unnecessary cost to them to have to support something that would become unsupportable as there is nothing to stop you flashing an incompatible firmware from another android device (other than realising your own stupidity). I for one think it is a great model.

Here's a device, safely locked to Asus updates. You want to risk bricking it? Fine, unlock it but don't come crying to us when you break it. Keeps both parties happy.
[Asus Transformer TF700] usern ameisval idandnot:
I totally agreed with you, dont get me wrong on this. The point I tried to make is that after you lost your guarentee they still dont let you access the ECU.
[Asus Transformer TF700] DIXES:
After having done this procedure, can I upgrade TF700T to Jelly bean 4.2.1 firmware? And when I upgrade it, the NVFlash backup still works for un-brick? Thanks.
[Asus Transformer TF700] TitanUranus:
Yes, you can downgrade to 9.4.5.30 if and only if you have created your NVFlash backup files. If you already have any bootloader newer than .26 (which is likely as it's a really old firmware) you can't do this though. Also, unless you are not used to messing about with these things, or don't have experience I would recommend creating the backup only in case of dire problems. Unless you are good with computer/tablets or are very keen to learn I wouldn't try downgrading except if you have actually bricked the device. It took me about 3 days of considerable research and help to figure out how to restore my bricked TF700 using the NVFlash backup.

In short, if you can do it, make the backup files "just in case" and hope to hell you never have to use them!
[Asus Transformer TF700] DIXES:
My device is already on Jelly Bean 4.1.1 now, should I downgrade to ICS just for creating the NVFlash backup then upgrade to Jelly Bean again?
[Asus Transformer TF700] TitanUranus:
You cannot downgrade. You need to have backed up using NVFlash BEFORE any bootloader updates. Since you have updated without creating the backup files it is too late I'm afraid.
[Asus Transformer TF700] DIXES:
Due to flash an old version blob is impossible or it will not flash old version bootloader while flashing an old version blob?
