Been waiting. Always ready for testing
And just be sure, it doesn't need unlocked bootloader, right?

Nah, this phone doesn't even support unlocking.

I tried it yesterday but it went black screen right after booting (after playing bootanimation for like 5 minutes). It seemed to be powered on but the screen was totally like off. And adb logcat was crazy with error messages like java exceptions & avc denied read/write etc. Gonna try again today since I forgot to screenshot it.

Attempt 2

# Was using stock firmware
# Installed TWRP 3.6.0_9-2 with MiFlash 2020.3.14.0
# Allowed system modification at TWRP startup
# Wiped data, dalvik/art, cache
# Installed ROM, no error in TWRP
# Rebooting: bootanimation plays, 180 degree rotated
# Black screen. But screen is actually on
# Phone connects to PC only in adb mode, no MTP
# Screen sharing to PC, still black
# Rebooting doesn't help, and the bootanimation takes like 5 mins every time

Here's some logcat.

This phone is a bit weird that the screen likes rotating on different variants of the phones, very nicely done, OPPO.

It will take a while to boot after the boot animation stops as it is loading SystemUI, you can try to format userdata as encryption seems to be dead currently.

You have to FORMAT DATA and type yes. The option is present by the side of advanced wipe. It is going to format your internal storage, so you have to flash it with SD card or otg

Hello,
Please excuse me but does calling and camera work fine? Also does audio, wifi home button work? Please reply!

Hello,

"No calling" because no imei, camera is also not working, audio is not implemented so "no audio", "wifi works", home button is also not working. Sed. There is no fix for above and not coming anytime soon. Maybe after two to three years. RIP this phone
