(01-12-2021, 10:06 AM)lolvatveo In research download tool setting I select power off after flash, put vbmeta first and flash custom recovery later, also changed the name to be the same as stock. I tried many times but doesn't boot to menu it hang forever, i open the phone case cover to disconnect the capable pin then flash stock vbmeta then it boots normally. Phone don't accept these file or vbmeta custom not suitableohh, maybe I got the problem, try with flag 0 when creating custom signed vbmeta and flash that using fastboot
fastboot flash vbmeta vbmeta.img
then reboot
fastboot reboot
check is you can reboot to system without bootloop or not

thanks I will try with flag 0, my phone can't flash through adb fastboot when not root (fastboot flag locked) need #SU permission to flash.

I can unlock OEM and USB Debug, this SPD can only flash via Research/SPD/Factory Tool if not Root. I tried many ways to unlock it with fastboot command, it didn't work: flashing flag locked. better is research tools
