Also, you might need a newer recovery for more recent ROMs. There are both 126.96.36.199 and 188.8.131.52 versions available in the development section.
I did everything as you posted:
1. Downloaded the most current firmware for the TF300T from the Asus site.
2. Pushed it to my device using fastboot
3. Installed custom recovery for my version of Android
The Installation bar completed after I pushed the firmware & recovery. It just took long to reboot. I read that you have to let the ROM "stabilize," so I suspect it might have been the cause of the hang. Everything went pretty smooth after the reboot, though. I installed TWRP 184.108.40.206 (as you posted above) and installed a new ROM. Thank you very much for taking the time to reply. I love this update!
