First off I want to thank @lj50036 for his time and most of all his patients in helping me bring my TF300T back to life I can't thank him enough!! His original post on the TF700T is here. Make sure you go thank him!!

You must have the NVFlash generated files from AndroidRoot.Mobi for ICS or JB.

This is what I did and it might not work for your specific situation. I performed this on a Mint 15 32 bit machine. This is very important (EDIT: This has also been done on Mint 64bit); Ubuntu might not work and would not work for me .

My situation:
I had flashed the wrong recovery (TWRP 2.6.3.0). This left me with only being able to boot into a recovery that would not mount anything but it would boot into APX mode.​

What you will end up needing:
blob.bin
unlock-token.img
factory-config.img
bricksafe.img

Also needed:

Fully charged TF300T (Just plug it in, it will charge no matter what...If not, you don’t need my help!!!!)
Asus data cable
Linux Mint 15 (32 bit) PC
Stock firmware blob (from asus's website. Make sure you get the right one) Download
nvflash and wheelie Download
And fastboot for your PC

You might also need TWRP 2.5.0.0 Download


Mint

1) Lets start with Mint 15 (32 bit) Download and how to make a bootable USB. instructions this has got to be one of the easiest OS’s I have installed and setting up dual boot is cake.

2) Once Mint is booted you want to update it, and it’s a little broken but it’s what I did and you will get some updates. Click where the start menu is in windows find the search field and lookup update manager. Run it and download what you can.

3) Extract wheelie and nvflash to your home folder...
Extract your stock firmware in your downloads folder twice...You will see a blob (this is not a .blob file make sure you put that in the name) file rename it boot.blob and move it to your home folder...
Move the above mentioned device specific files to your home folder..
blob.bin
unlock-token.img
factory-config.img
bricksafe.img
nvflash
wheelie
boot.blob (we renamed it in the last step)


4) Next we need to install fastboot, this is straight up Linux voodoo, open terminal and get comfy cause that’s what you’re going to be using. next type
Code: 
fastboot
it will prompt you with the command to install fastboot.

These inputs and outputs are from lj50036 post on the TF700T and may very from your outputs. I used the processes and it worked for me.

Lets get started

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 output of my process
Code: 
sudo ./wheelie --blob blob.bin

lj50036@cmbroms:~ > sudo ./wheelie --blob blob.bin
OUTPUT
Wheelie 0.1 - Preflight for nvflash.

It may shutdown after each command, get back into nvflash with the above steps.....

Code: 
sudo ./nvflash -r --go

lj50036@cmbroms:~ > sudo ./nvflash -r --go
OUTPUT
Nvflash v1.13.87205 started
[resume mode]

This is where I ran into problems that didn’t work with the TF700T recovery process. I could not boot into Fastboot with the holding the power and the volume down no matter what I did. this is how we got around it.
download the correct .blob from TWRP rename it twrp.blob then run

Code: 
sudo ./nvflash -r --download 5 twrp.blob

I don't have output for this.

At this point I could boot into the OS, but still not into fastboot. My OS had the option to reboot to download. If you don’t have this option you could try this or this. But the best way is via the buttons.

Run these command in fastboot in this order

The next command is to just verify your computer can see your device

Code: 
sudo fastboot devices

INPUT
lj50036@cmbroms:~ > sudo fastboot devices
OUTPUT
015d2bbce2501405 fastboot

Code: 
sudo fastboot erase system

Thanks for your docs, only a question please, are necessarily forced to use "Linux Mint 15 (32 bit) PC" or can i use Windows as I did to generate the img and blob?
I don't understand this step, "nvflash" work fine to download this file, it doesn't work during the write from Windows command prompt?

I can confirm this working on mint 15 32 bit, mint 15 64 bit, and mint 16 64 bit.. I would stay away from windows if at all possible....Thx lj

Did you come from a brick or did you just use nvflash to flash a recovery??

My device is TF201.
Here is my long story: (search for my post)
http://xdaforums.com/showthread.php?p=50690267

In short, i cannot get fastboot but can get to APX (power + up)

Was thinking of trying your steps but I dun understand how to get twrp.blob.

Also, prior to my brick i flashed some cwm recovery. Does that matter?
I have all the output files from the flatline thingy.

Any ideas?

First, let me thank you for responding. Really appreciate this.

You mean I actually have hope even that now I only have a black screen + APX device detected in windows 7?

Should we continue this on this thread? Since its tf201 and not tf300
Or should we continue on IRC?
http://xdaforums.com/showthread.php?p=50690267
(please read my story (10th reply down))

I have no idea how to proceed at all and dun wish to do anything silly.
Should i follow what you did or this:

[GUIDE] nvFlash General Users Guide [Unbrick/Recover/Downgrade/Upgrade]- TF201
http://xdaforums.com/showthread.php?p=50691902
-----------------------
1. Download an un-blob'd ROM (links below). [Advanced users can use BlobTools (blobunpack) and unblob a ROM. Make sure you have compatible unblob'd images of the bootloader, recovery, kernel & system]
2. Extract wheelie, nvFlash and the unblob'd ROM to a directory (avoid spaces in the directory path)
3. Start your device in APX mode [Power On + Volume Up]. Your tablet screen will remain blank in APX mode.
4. Bootstrap your device (enter nvFlash mode) while your device is in APX mode using wheelie
wheelie.exe --blob blob.bin
5. After wheelie does it's job, your device will be ready in nvFlash mode. You can now begin the process.
6. We start with the bootloader. In the case of the un-blob'd ROMs below, this is the blob.EBT file. To flash the bootloader, use this command:
nvflash.exe -r --download 4 blob.EBT
7. Next we move to the recovery image. In the case of the un-blob'd ROMs below, this is the blob.SOS file. To flash the recovery image, use this command:
nvflash.exe -r --download 5 blob.SOS
8. Next we move to the boot image. In the case of the un-blob'd ROMs below, this is the blob.LNX file. To flash the boot image, use this command:
nvflash.exe -r --download 6 blob.LNX
9. Next we move to the system image. In the case of the un-blob'd ROMs below, this is the blob.APP file. To flash the system image, use this command:
nvflash.exe -r --download 10 blob.APP
10. Finally, we reboot the device. After you run the following command, you will see the text "AndroidRoot 9.4.2.28" and your device should reboot in a few seconds. If you device does not reboot after you see the text, force a reboot (long press the Power button)
nvflash.exe -r --go

Thanks for your great tutorials. I did this process on my TF201 and it worked great. Trying to do the same on my teenagers TF300T and I'm running into an error.
When I do fastboot -i 0x0b05 flash system boot.blob I get error: cannot open "boot.blob"
Tried renaming the file, as well at using another copy of the file from my cloud. I noticed the file is listed as a txt file not a blob file

Never mind. Used the stock blob and it worked.

    unlock-token.img
    factory-config.img
    bricksafe.img
    nvflash
    wheelie
    boot.blob (we renamed it in the last step)


    4) Next we need to install fastboot, this is straight up Linux voodoo, open terminal and get comfy cause that’s what you’re going to be using. next type
    Code: 
    fastboot
    it will prompt you with the command to install fastboot.

    These inputs and outputs are from lj50036 post on the TF700T and may very from your outputs. I used the processes and it worked for me.

    Lets get started

    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 output of my process
    Code: 
    sudo ./wheelie --blob blob.bin

    lj50036@cmbroms:~ > sudo ./wheelie --blob blob.bin
    OUTPUT
    Wheelie 0.1 - Preflight for nvflash.

    OUTPUT

    [resume mode]

    This is where I ran into problems that didn’t work with the TF700T recovery process. I could not boot into Fastboot with the holding the power and the volume down no matter what I did. this is how we got around it.
    download the correct .blob from TWRP rename it twrp.blob then run

    Code: 
    sudo ./nvflash -r --download 5 twrp.blob

    I don't have output for this.

    At this point I could boot into the OS, but still not into fastboot. My OS had the option to reboot to download. If you don’t have this option you could try this or this. But the best way is via the buttons.

    Run these command in fastboot in this order

    The next command is to just verify your computer can see your device

    Code: 
    sudo fastboot devices

    INPUT
    lj50036@cmbroms:~ > sudo fastboot devices
    OUTPUT
    015d2bbce2501405 fastboot

    Code: 
    sudo fastboot erase system

    INPUT
    lj50036@cmbroms:~ > sudo fastboot erase system
    OUTPUT

    OUTPUT
    erasing 'recovery'...

    Code: 
    sudo fastboot -w

    INPUT
    lj50036@cmbroms:~ > sudo fastboot -w
    OUTPUT

    erasing 'cache'...

    At this point it just hangs on erasing 'cache'
    I just close terminal and open new one, and run the next command
    If your tablet hangs just reboot back into fastboot again

    Code: 
     sudo fastboot erase boot

    INPUT
    lj50036@cmbroms:~ > sudo fastboot erase boot
    OUTPUT
    erasing 'boot'...

    OUTPUT

    Code:

    OUTPUT

    finished. total time: 2.843s

    Code: 
    sudo fastboot -i 0x0B05 flash system boot.blob

    During the sending/writing process of this step you will get the blue bar on your screen.....

    INPUT

    OUTPUT

    Thanks for your docs, only a question please, are necessarily forced to use "Linux Mint 15 (32 bit) PC" or can i use Windows as I did to generate the img and blob?
    I don't understand this step, "nvflash" work fine to download this file, it doesn't work during the write from Windows command prompt?
    Click to expand...
    Click to collapse

    I can confirm this working on mint 15 32 bit, mint 15 64 bit, and mint 16 64 bit.. I would stay away from windows if at all possible....Thx lj

    I would like to point out for nvflash -r --download 5 twrp.blob my output was the following:
    Code: 
    Nvflash v1.13.87205 started
[resume mode]
sending file: twrp.blob
- 8165480/8165480 bytes sent
twrp.blob sent successfully
    Then the device proceeded to reboot into android :)

    Thanks for your great tutorials. I did this process on my TF201 and it worked great. Trying to do the same on my teenagers TF300T and I'm running into an error.
    When I do fastboot -i 0x0b05 flash system boot.blob I get error: cannot open "boot.blob"
    Tried renaming the file, as well at using another copy of the file from my cloud. I noticed the file is listed as a txt file not a blob file

    Never mind. Used the stock blob and it worked.
