My Xiaomi Mi 9T's audio and microphone stopped working. I confirmed it is a firmware issue by using CRT mode and given that my bluetooth earbuds also do not output any audio. After downloading the correct fastboot ROM (Stable Global 12.1.4.0) and flashing it on my phone, the issue has not been fixed. After further Chat-GPTing I understood that the non-existing modem.img, dpso.img and persist.img where the reason behind that, because they're the ones responsible for audio processing and whatnot. However, I can't seem to find a 12.1.4.0 ROM having those files, and would like to know if I can flash those singular ones from an older ROM.
