[ZenFone 2 Q&A, Help & Troubleshooting] ryankabir:
Well I'm not gonna dig too deep into the twrp touch issues (there could be conflicting drivers or even something weird i noticed in twrp302 anything below 20% batt (or if batstats corrupt) then the touch goes craycray.. so lets ignore that..

this thread is getting too heavy i won't have time - so - you can always backup ur data partition so no worries there.. nothing to lose..

one problem at a time.. as I said in first post my phone was bricked much worse i had mismatched fastdroidboot and bootimg and after pressing power on maybe 4-5 times.. it would only turn on once.. sometimes on and immediately off... sometimes on stuck on logo.. sometimes on and no logo but screen is black (corrupt splash)..

so lets just try to go baaaaaack to the futureeeeeee ... Ok I found the script I made (after 8 hours of trying EVERY combination from different guides I just took individual components and made my own.. ) -

I'm writing this in a hurry so please use my first reply to get the XFTS Ubrick Guide for the Files + get the LOLLIPOP One Click BL Unlock + Lollipop Raw image... Their Guide wants you to use Asus Flash but that program failed me every time... so I have got a differnt way to do it..

I'm copying this directly from my own script (so you can change if any paths/names different)... but do not change the order or sequence

Using OneClick (keep the unlock1234 files saved separately for later use)...

If you have these unlocked I just say do it again anyway - no harm...

Unlock Bootloader for LP Stock (even if you have MM you must downgrade by this same method)

#flash old droidboot for LP stock Bootloader

# must run reboot bootloader once with this droidboot before continuing - dn't skip this
# unlock bootloader (use files provided inside oneclick tool but instead of using their script, manually do it - more reliable)

#if you get failed/error at oem stop - reboot to Bootloader (VOLUP+Power long press -

Release power at Asus Logo or long vibration) and re-do the last step

#if all done so far

fastboot reboot-bootloader
#white Asus logo means unlocked loader

fastboot flash recovery twrp3.img

#toggle Up to choose Recovery - quick tap VOLUP+Power
#twrp will start

install Custom_MM_Rom.zip
#likely it will fail giving IFW 7 error - (intentionally did NOT put MM BL here), so
install Asus_MM_WW_420_184.zip (stock on stock only)
#let it be fully done, verify working MM stock OS
#check if it works - *sign* test your touch screen quickly and in dev tools Keep Debugging ENabled
#then power off - or if you have more options directly choose reboot
#during reboot vibration hit VOLUP+P to Fastboot

####RE-DO Entire first half again
