I'm trying to build TWRP for Symphony Z60 Plus,
Chipset - Unisoc T616, Stock Android, device has A/B (vendor_boot) partition, no recovery partition,

DT : https://github.com/Bakar53/android_symphony_z60plus

After building this tree and flashing the new vendor_boot.img, the device seems to boot into recovery with the boot logo screen. The screen turns off after around 60 seconds, and then wakes up and turns off again when pressing the power button. When the screen is about to turn off, touching it briefly makes it brighter, so both brightness and touch seem to be working. 

However, the boot logo doesn’t disappear, the TWRP UI does not appear, and ADB does not detect the device. 

Could you kindly help me fix these issues or guide me to the proper source tree for TWRP on this device? Thanks in advance.

@hovatek, I've build TWRP using hovatek builder (work id 1XfIHZMpJ8OauzKBUi30 ), but still now TWRP UI isn't appearing (only bootlogo) and now adb works, so I could collect some logs & logs are attached,

I've commented out the two custom flags you added and queued for rebuild

Code:

# TW_DEFAULT_BRIGHTNESS := 25 # TW_EXCLUDE_MTP := false

Try the new build and give feedback.
graphics_drm.cpp might also need to be tweaked, but we'll come to that later

I have completely refactored the DRM of TWRP and resolved the compatibility issue on Unisoc. You can refer to https://github.com/rtyutechstudio/unisoc...code_patch for the solution
