[ZenFone 2 Q&A, Help & Troubleshooting] cjdandy:
Hi Guys

please help me fix a few problem which are driving me crazy.

here's the story

my zenfone is z00ad 4ram 64gb version, everything was fine until recently, i tried upgrade to Android M using asus flash tool with the latest raw file provided by realyoti, as a result got it hard bricked, black screen no vibration and pc could not detect the device too

took it to a repair center (there is no official asus service center in my country), they were successful doing a boot repair but couldn't flash any roms ,they told me that they had to replace the hard drive of the device, did so but still took them more than a week to call me saying the phone is ready

they somehow changed my phone to a "Z00ADA" variant with a rooted CN rom, the serail number was 111111111 in the settings, but in the bootloader the serial number was 0123456789..G, and my imei was different from what the box said but since they were both in the back of my phone i assumed it is ok. there were too many Chinese apps and no gapps, so i decided to change to ww version, but there were no recovery and when i tired to boot into recovery phone just booted into the bootloader instead, let the repair technician know asked him why there is no recovery told me that he had to replace the motherboard to do that and that i should use the device as is or give him yet more time to solve the recovery and Z00ADA version, it was nearly a month so i told him no thanks

found the guide on how to do it myself , using fastboot comands and upgraded straight to the latest android M, by the time i finished the typing fastboot reboot that i noticed the op had written its best to flash a L rom before flashing M rom ( which i didnt, and since there was no APD.IMG in the MM rom i skipped flashing it) phone booted up perfectly though

upon connecting the phone pc still recognized the device as Z00ADA when the bootloader was Z00AD, strange!

phone was working fine except for the fast-charge which was working sometimes and not the other times and the com process.phone.stopped working error

then one morning when i restarted the phone it didn't turn back on, thought it is because of the come.phone .process so wiped cache did a factory reset but ran out of battery when booting up. recharged it when i got home and phone booted up but those two problems i mentioned was persistent, then fastcharging stopped working and it was taking me 8 hours to recharge, decided to flash again but pc was not recognizing the device, used sd card to flash the update zip and did a factory reset, phone was ok with those same problems

found a guide deleted every intel driver using a tool and got the pc to recognize my device as Z00AD, since fastcharging was ok in android LP tried to downgrade , used fastboot comands flashed everything but got error in

fastboot oem partition /tmp/partition.tbl

fastboot flash /tmp/partition.tbl partition.tbl

phone was stuck in boot screen , used asus flash tool flashed the LP raw and phone booted up

but the screen was acting up and was doing things on its own, used asus flash tool to upgrade to MM raw , phone booted up screen was fine except when i tried the one layer mode in asus zenui launcher, changed back to two layer mode and it is fine til now, fast charging is working too

but now i have this strange problem, i have to plug the charger in and switch the phone on otherwise after loading the home screen phone will shut down though i have like 70 in the battery , and sometimes the phone shuts down when im using it

please tell me what to do , had i messed the phone changing from Z00ADA to Z00ad , it was working fine on that cn rom

too long didn't read, my phone got bricked , had it repaired and upgraded to android MM, but the phone either shuts down automatically or doesn't stay in home screen if it is not plugged

please help me solve it and change my serial number to the original one

thanks in advance for your replies:angel:

Edit: so today i downgraded to Android LP WW_ZE551ML_2.20.40.194_20160713 using asus flash tool 1.0.0.17, and i no longer had the issue, it didn't turn off, used it for a whole day like that for testing purposes and i got to 5% battery percentage without no hiccups lol, seeing that the issue worked itself out i decided to upgrade to Android MM UL-Z00A-WW-4.21.40.352 using update from adb sideload command and then wiped cache and data and rebooted the system, the welcome screen popped up and as i was choosing the language the phone shut itself down again, what is the problem , is there any log file i could share with you guys to see what is causing this system shut downs?

Edit 2: i took out the sim cards and phone was ok . it was not turning off, tested all apps installed and i noticed every app is working fine except for camera, the second i clicked to take a picture the phone shut down and was not switching back on unplugged, how ever i can take pictures and have both sims installed and phone is functioning properly when it is plugged to power supply. can somebody help me fix it?
