before flashing pixelplusui to see if it doesn't break bt first flash latest miui version 12.5.1 or smt then flash miui 220.127.116.11 after that you can update again to latest miui. Then Bluetooth will work again. This Bluetooth problem doesn't get fixed when you just install the stock firmware or at least that's my case.
Maybe you should try factory reset after installing pro Fw
theres no way factory reset do anything to /system or /vendor... it only wipes /data /cache u didnt know that??? and before any flashing new rom there is always /data /cache wipe. Others including me tried installing latest P59 fw and issue still persists so idk if hes just lucky or what.Maybe you should try factory reset after installing pro Fw
I have used PE same issue there but when I moved back to miui the issue is still there
So I tried factory reset and it worked
You should give a try on PE after flashing p59 try to factory reset in PE and tell did it worked or not
Well in my case when I'm in miui I'm using p57 based fw and when I moved to PE Bluetooth issue is there. Maybe it's p57 fw that's causing issue, I'm not sure.theres no way factory reset do anything to /system or /vendor... it only wipes /data /cache u didnt know that??? and before any flashing new rom there is always /data /cache wipe. Others including me tried installing latest P59 fw and issue still persists so idk if hes just lucky or what.
Flash Miui 12.5 fastboot. Do Factory reset in Miui settings. Recheck Bluetooth after done. If it work, continue with flashing any you want and dont flash rom based on PE tree or your Bluetooth will be same again.
sorry bro, i have followed the guide above, and I've installed pixelplusui and everything is okay, bluetooth issues has been gone
Bluetooth does not work well due to nvdata, also after PE 12 there are many problems in the operation of the device, you can fix it either by flashing to miui 12.0 (after that you can flash to any firmware), or by flashing this patch in twrp - click, after application it, if you restored imei via meta mode, everything will fly off and you will have to do everything all over again.I have been using PE+12 (May 2022) and I have went back to MIUI. Since then I have been experiencing the low bluetooth range on MIUI (although it was fixed in the recent PE updates)
I tried re-writing presist but the problem is still there. Is there any way to write the MIUI files responsible for the bluetooth connectivity?
