This is a general users guide to unbricking your tf700t...
This is only what I did, It was successfull for me.
I did this on linux mint 32 bit, so thats what I can help with. Im sure it can be done on windows but who would want to!!!!!!LOL
I will help anyone that needs it of course... No matter the os... Just let me know!!!!
What you need
Your device specific nvflash backup files generated while enabling nvflash.
!!!!!!!!If you dont have them there is no help for you!!!!!!
- blob.bin
- bootloader.ebt
- unlock-token.img
- factory-config.img
- bricksafe.img
Also needed
- A tf700t (Its bad now, but all will be ok)
- Fully charged tf700t (Just plug it in, it will charge no matter what...If not you dont need my help!!!!)
- Asus data cable
- Linux Mint 32bit PC
- Super user permission
- Stock firmware blob (from asus's web site, make sure you get the right one)
- nvflash and wheelie
- And fastboot for your PC

nvflash/wheelie-Windows
Asus Stock firmware---MAKE SURE YOU GET THE CORRECT SKU FOR YOUR 700
INSTRUCTIONS
Extract wheelie and nvflash to your home folder...
Extract your stock firmware in your downloads folder twice...You will see a blob file rename it boot.blob and move it to your home folder...
Move the above mentioned device specific files to your home folder...
In your home folder you should have
- blob.bin
- unlock-token.img
- factory-config.img
- bricksafe.img
- bootloader.ebt
- nvflash
- wheelie
- boot.blob (we renamed it in the last step)
Start your device in APX mode [Power On + Volume Up]. Your tablet screen will remain blank in APX mode....
Bootstrap your device (enter nvFlash mode) while your device is in APX mode using wheelie....
I am going to show you the outpus of my process

hold power button and volume down to boot into fastboot...You will now have fastboot.

Hi.
I'm restoring my TF201 to its original condition sing the files I saved from nvflash in 2012 when I first bought the tablet.
I've connected in APX mode and flashed the blob.bin, then the tablet rebooted. I went back into APX mode and entered 'nvflash -r --download 7 unlock-token.img' and I get the following:-
NvFlash v1.13.87205 started
[resume mode]
Then it just stays like that!
I've tried to find different versions of nvflash becasue some people report that it helps, but no luck (really hard to find newest Win 7 version for TF201).
I've tried running as administrator: same output.
I'm using Win 7 64bit.
Help?
wheelie --blob blob.bin
The tablet should not reboot after you run the blob.bin ?
What is the output of the command .....
Code:wheelie --blob blob.bin
Thx Josh

Hi Josh.
Firstly, thanks for your help with this.
I've just connected the TF201 in APX mode (universal naked driver) and entered
wheelie --blob blob.bin
the output is:-
Code:C:\flashing\nvflash>wheelie --blob blob.bin Wheelie 0.1 - Preflight for nvflash.

Phil.
I'm assuming it was a reboot, the TF201 screen goes black and then it says:-
NvFlash recovery mode / NvSp Server
Chip UiD: (random string here)
!!!!!device update success!!!!!
but then all of the other nvflash commands worked so I'm guessing it was right?
I've just worked out that the screen with the three icons (wipe data, usb and android) is where you start fastboot (usb icon). the TF201 is now showing up in device manager as 'Asus Android Bootloader Interface', but every fastboot command returns 'access is denied' as the output...
Shoot me a hangouts or email at jl52741@gmail.com
When you get some time and if you would like any help looking into this issue ....

Think I sorted it; I tried another version of fastboot I have and it worked! Just waiting for it to finish sending the boot.blob to the system partition...it's taking rather a long time...how long should I wait and what should I do if it's stuck?
The time it took for mine are posted in the OP ....
Not sure why it would be stuck, I was not there for what you did ....

Sorry, edited last post before I noticed your reply.

Tried to recover from brick, I don't get bootloadrer.
I reflashed the bootloder but nothing works so far
I got the files:
blob.bin
bootloader.ebt
I'm missing the files
unlock-token.img
factory-config.img
bricksafe.img
any chance to save my tablet ?
sudo ./wheelie --blob blob.bin
sudo ./nvflash -r --download 7 unlock-token.img
sudo ./nvflash -r --download 14 factory-config.img
sudo ./nvflash -r --rawdevicewrite 0 2944 bricksafe.img
sudo ./nvflash -r --go
fastboot devices
fastboot erase system
fastboot erase recovery
fastboot -w
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0b05 flash system boot.blob
fastboot -i 0x0B05 reboot
nvflash --setbct --create --configfile flash.cfg --bl bootloader.ebt --bct recovery.bct --blob blob.bin
So I got Ubuntu up and running and I have the adb and fastboot drivers installed. I also dl'ed the linux wheelie and nvflash files. The computer can see my device when I run fastboot devices command but it won't run wheelie from the directory I created for it. Where do I put my files so the terminal can run them?
