[Q] Nexus 7 (2012) - Converting to f2fs - stuck on google screen - bootloop? topic

a few times now over the months with my nexus 7 (2012) i have tried to convert to fsf2 with twrp manually and always seem to get stuck on the google screen for over 5 - 10 minutes, only once from my first try after simulating a battery pull (holding all the buttons down) I got past the google screen in normal quick time, but after trying my first reboot i got stuck on the google screen again. How long is the google screen at most supposed to be on the screen for before launiching the rom boot screen after converting to f2fs? Is the google screen bootlooping?

Most recent try at converting...

Reboot into TWRP (2.8.3.0) recovery
Wipe the system, data, cache, dalvik cache
Change system, cache, and data (one at a time manually) from EXT4 to F2FS
Reboot Recovery
In main TWRP menu, hit "Mount", and "Enable MTP" if it is not already enabled
Drag the two zip files you downloaded into the TWRP folder
Hit "Install", find the "TWRP" folder
Select the Slim group zip and swipe to flash
Go back and select the gapps zip and swipe to flash
Reboot the system
Wait a few minutes to boot up
stuck on google screen????
