This works 100 % ( frp bypass ) !
Phone is locked by google account , setting back to factory settings dose not help !
Short story what you have to do :
1 unlock bootloader -> ZF4_ZE554KL_UNLOCK -> ze554kl_unlock.bat
2 install custom recovery like TWRP 3.1
3 disable dm-verity -> flash -> no-verity-opt-encrypt-6.0 , reboot to recovery , do a full system backup :)
4 this is very important don't forget to flash dm-verity , otherwise boot-loop !
5 clear cache or do a factory reset
6 done !
7 when the phone starts , every time there will be a annoying message , totally normal ,don't worry !

Here are some pictures about the unlocking process :)

Yes, it works on 8.0, I did all the OTAs first. Not sure on warranty.

Tips:
* Get Developer mode and ADB shell working first (tell the phone to always trust your computer)
* Volume Up+Power on for fastboot mode, Volume Down+Power on for recovery. Long hold power to force phone off (unplug USB first).
* Use this version of TWRP (thanks shakalaca): https://www.androidfilehost.com/?fid=889964283620764455
* no_verity_opt_encrypt 6.0 works: https://build.nethunter.com/android-tools/no-verity-opt-encrypt/
* Make sure your USB cable is unplugged when booting to TWRP recovery or it will hang. You can plug it back in once TWRP loads.

The problem has already come with the device since I bought zenfone 4

What did you do to keep your device in a bootloop?
hello, friend, I just can not say it's already the third time he has entered bootlooping without me doing absolutely nothing. my question is several first I can do the procedure of unlocking the bootloader with the device in bootlooping. secondly if I make a hard reset I start the device normally.third and last these bootloader unlock files are for android 8.0 and 8.1:confused:

From what I know it is possible to unlock the bootloader with the device in bootloop (but since the problem is something in /data). But if it is already the third time that happens, how did you solve the other two times?
And the unofficial unlock method works on Android 8 (ASUS has never released Android 8.1 for Zenfone 4).

    Just wanted to say that this method worked on the Pie beta as well (tried myself), in case someone is wondering whether it works or not.

    Does this activate dm-verity? Unlock image when the device turns on?
    Are they still being updated via OTA?

    Did you unlock bootloader by official or this one method?

    I said this method worked, if this method is unofficial (as its written in the title), which one did I use? Kinda obvious I guess...
