Fastboot boot not work on android 10
Be careful when installing or updating modules, I updated the busybox module and the phone wouldn't boot anymore, just went straight to fastboot with no boot animation.
I had to flash stock boot img to boot again, but then it's not possible to remove the bad module.
Backed up my sdcard and apps and rolled back to pie until there's working twrp.
