Thanks so much for the guide. I was using the LCD Density App and that thing jacked my Infinity up big time. I will never use that application again. It wanted SuperUser clearance to save the Pixel Density, then when I checked Save & Reboot, my Infinity never turned on again. It just got stuck at the ASUS screen and wouldn't turn off. If I tried to power down, it just turned back on and stuck at the first Asus Screen.
I used the following directions and was able to get back to stock firmware.
*** Factory Restore after a softbrick ***
When You Need This?
* if you get stuck on Asus boot screen (the one with the spinning wheel)
Note: You need to have a working recovery (stock or custom) in order to use this method.
========= Recover with stock recovery =========
1) Download the latest firmware from Asus site (based os your SKU,eg. ww 184.108.40.206)
2) Extract the .zip file somewere on your desktop (the result will be another .zip file,use it for step 3)
3) Rename the extracted archive to "EP201_768_SDUPDATE" (without the " ") and upload it to a MicroSD card
4) Insert the MicroSD card in your tablet and use this button combination to Power ON and go to recovery --> Start the tablet by pressing Volume Down and POWER togheter for 5 seconds ,a message will inform you that you have 5 seconds to enter the recovery,press Volume UP before the 5 seconds expire.
At this point the device will go in recovery and should start updating your firmware .
So yeah, thanks for this guide and beware of the Pixel Density Application. I know someone from here created it, but It could not have been more clear that it messed my tablet up since I had never had a problem until I gave it SuperUser Clearance then it never turned on again.
