Android won't boot after unsuccesful wipe operation
I was having the same issue as this. I was in a "recovery boot loop" and could not get to the recovery options.  I did have ADB access to the device after I installed the "Naked Drivers". Once I did this I was able to see the device using the command "adb devices". The MAGIC command once I had adb access was "adb reboot bootloader" BAM! It rebooted mid bootloop and I was able to select the fastboot option. I followed all of matt95's instructions above including following the link he provided to XDA. The link at XDA explained how to get the "blob" file. It's easy, you download the current rom from ASUS and extract the blob file from it. I literally copied and pasted each command with the exception of the path to my blob file and my TF201 has been resurrected! 

Good Luck!
