I hope this time EU version will work, I've been stuck with 8.1.3.0 for too long now (but too lazy to switch to dev ROM).
I will update this reply accordingly based on test results:
Booting OK (I clean cache + dalvik, so even after booting there will be recompilation of all my apps)
Navigation button will be disabled, press home + power together to reactivate
Starts from SuperSU 2.46 to root (I don't test newer version zips). Probably can't start clean, need 7.5.2.0 for first flash, then do dirty flash on top of it
Quick ball enabled (can't disable, perhaps requires reboot) with option "temporarily shown in landscape mode" (EDIT: yep, gone after reboot)
Default thermal throttle config still sucks even for mid gaming, yet a daemon (haven't found out what it is) keeps /system from being remounted rw! Will attempt changes from recovery (EDIT: changes from recovery successful, need to manually mount /dev/block/mmcblk0p11)
Feel free to ask if there's anything you want to me to test. Yay! Welcome 8.5.1.0!
