Poco F2 Pro Audio broken after upgraded to 19.1
Expected Behavior
Speakers should work properly.
Current Behavior
VLC Player, Pocket Casts...cannot work. So does the Phone app, I can neither make nor receive a call.
Possible Solution
I don't know. I found this similar issue which suggests that the firmware maybe not the latest. So I tried to update the firmware in these steps:
- Download the latest firmware from https://xiaomifirmwareupdater.com/firmware/
- Run
adb reboot sideload
adb sideload firmware.zip
But, the update was failed. The feedback message indicated that the Target SPL is downgrade to the Current SPL.
Steps to Reproduce
- Follow the official Manually upgrading LineageOS guide to finish the upgrade
