Well looks like this ROM doesn't want to play with me.
Just tried flashing it, after doing a proper wipe, followed by flashing the Devil 3.4 kernel' and at first impressions seem to work fine (besides the fact that it still did not pick up my 128GB microsd card in ext4 format. Also tried the microsd card in a card reader via USB OTG and no detection)
I then decided to turn the phone off (can't remember why). Later on, I turned it back on and the phone become somewhat unresponsive. I would attempt to unlock the lockscreen only for the the device to then return me back to the lockscreen. I tried pressing all the buttons, nothing.
I tried to quickly unlock and activate an app, nothing happened as a result and it would then send me back to the lockscreen.
Tried the power button to reboot the device, unresponsive; had to pull the battery to get back to TWRP 2.8.1.0 recovery (using this recovery as 2.8.4.0 may have been somehow connected to my previous problems of being stuck at the boot animation).
I have absolutely no idea why this ROM has been this troublesome. I really wanted this ROM for all its features/goodness,
I guess I'll just stick with my nandroid of BeanStalk (which has been getting somewhat sluggish), until a solution arises or the Dev decides to release an update.
