 * Your warranty is now void.

 * do some research if you have any concerns about features included in this ROM
 * before flashing it! YOU are choosing to make these modifications, and if

* I've test on 14.1060.1708.70 and older firmware and confirm working *

1. Download the file below
2. Put your phone into fastboot mode (power + volume up) and connect to your computer
3. Run ze554kl_unlock.bat
4. Phone should be unlocked with annoying splash screen ;)

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

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.

* 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):
* no_verity_opt_encrypt 6.0 works:
* 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.
