Hello Hovatek admins. I have already unlocked my bootloader and root my device (LB8A Android 9) using magisk. I ported twrp using the twrp Porter 1.5 and it was successful.however when I flashed twrp using fastboot, and I tried to boot to recovery, it just continue in an endless loop.it won't boot to recovery nor fastboot also and it's not shutting down as well. I had to open phone and remove battery connector to flash it back to stock.
In the stock rom I used, there was a vbmeta.img inside. What's d implication and is there any fix for the endless loop??
