This kind of all custom kernels need to be flashed by custom recovery like twrp? Can I flash this by original recovery? I just bought OP3T yesterday. I don't know anything. What I really want is changing my terrible vibration on OP3T. Need some help. (OP3T OOS 5.0.1)
You need to use TWRP to install. However, you can use fastboot to temporarily boot into TWRP if you want to keep the stock recovery
