Question Fix Xiaomi mi 11 - Speaker not working - Xiaomi Mi 11

Problem came after downloading android 14 (miui), both speakers stopped working and only the mic works when you call someone. I have downloaded latest package to see and reset but nothing works. What can I do?
is it possible to flash a stock rom (android 13 or other stable) with a locked bootloader? I don't want to wait 7 days to unlock the bootloader.

Bluetooth Problem

I have a problem with the Bluetooth module. When I first time turn it on, it's working normally but the second time it's never start. The only way is the reboot then work normally again, once.
ROM: MIUI 10 Xiaomi.EU 8.8.9
Same here my friend.
Is Rom problem
I use same rom and I have same problem too. What about who uses global rom?
Use 8.8.30 xiaomi.eu, no issues here (had similar BT issues on earlier versions). If you don't run this one or later maybe a clean flash helps.

This is a known problem with an easy fix.
BT stops working after deactivating it once or going to airplane mode.
You have to:
Put the phone in airplane mode
Reboot to recovery
Wipe ART/Dalvik and Cache
Reboot to system
afterwards it works.
Thanks to PMShodan for this hint

I tried this method, it works for a few days, then the problem recurs! Tt the moment no definitive solution
Do you think the problem is of the bluetooth driver, or is it a bug of the miui 10? strange that the xiaomi team has not yet found a solution
Hi guys, I still have the bluetooth bug, I have the miui 10 stable (oreo based) of the miui eu team. Is there a definitive solution? thank you
Same issues with the Bluetooth on Mi 8 Global with Miui 10 and I need to know if it is hardware or software, cause I want to use a custom Rom and I need to know if I am to use the warranty
- Bluetooth sometimes tries to connect to inactive device;
- Sometimes in messenger the phone doesn't switch to Bluetooth
Bluetooth is not working at all on MIUI 10 after air update.
When trying to turn it on it just shows error notification in the bottom of screen.

Mic fail in call - no sound transmitted

Hello,
This has been driving me nuts. I can't be heard in normal calls, the mic picks up nothing.
I am using global 9t pro.
I have tested the hardware and the mic is working. Speakerphone works also. All roms tried present the same problem (stock, lineage, Xiaomi.eu). I have now clean flashed stock MIUI 10 and updated to 11 and problem remains.
I've read there can be sim reader problems, but speakerphone seems to work. I've read there can be audio routing problems relating to headset with mic being detected, but I can't find evidence the phone thinks there is a headset connected. I've disabled Google Assistant and the problem remains.
What puzzles me is that even after a complete clean flash of stock rom there is no improvement.
Any advice would be greatly appreciated.
Thanks

Hello I had a similar problem, my autorotation and mic started to fail and I got confused, after some research it turns out if I flash MIUI 11 and go back to MIUI 10 a partition called persist gets deleted and it completely messes up your sensors and it won't get fixed regardless you flash another rom, what I did was download fastboot rom and flash it. If that doesn't fix it extract the persist.img from the rom files and flash it through TWRP and it should go back to working. Wait now that I think about it you try flash persist.img from the files and if it doesn't work then you flash the fastboot rom. Good luck

Call Audio not working on Android 10 - CN Mi 9

Hello - back here again to rephrase my issue, as I now have two devices in the exact same situation.
Two Chinese brand new model Mi 9's. Both have microphone issues when placing calls on any Android 10 MIUI or AOSP (Stock or Custom) ROMs.
MIUI 10 and Android 9.0 AOSP ROMs (Like Evolution/PE) work fine. Anything Android 10 based (MIUI11 or AOSP), need to hit Speakerphone button first, then disable it, and microphone works.
Already used fastboot files with miflash to go back to stock MIUI 10 China ROM, OTA update to MIUI 11, and then it stops working. Tried EEA, Global, etc.
What am I missing here? What do I need to flash before upgrading to MIUI 11 even off a fresh fastboot reset?
Thanks in advance

Honor 9 lite camera & flashlight problems

Hi,
I'm hoping someone out there can maybe help me with this please?
I have an Honor 9 Lite (LLD-L31C432) & recently the camera & flashlight stopped working. I've tried a number of other camera apps (the P20 ported camera, various google cams etc) but none work - all either open to a black screen & shut down immediately or else just say the app has crashed, etc.
The phone is bootloader unlocked and was on stock rom (LLD-GRP2-OVS-9.1.0.121). A few months ago I switched to Openkirin's Resurrection Remix OS 7.0.1 Beta 1 ROM & all worked ok (I had the stock camera, a Google Cam version and the P20 camera all working), but due to bluetooth problems I tried the Openkirin AOSP 10 Preview 1 ROM. Had a few problems with this one so tried to return to the stock ROM and had a lot of trouble getting it working again (bootloops, etc).
Eventually got the stock firmware back on but then noticed that the camera & flash no longer worked. Since then I've returned to both the Resurrection Remix ROM and the AOSP 10 Preview 1 (& Preview 2) ROMs but the problem still remains. Is it possible that I've broken the camera when fastboot flashing or using TWRP? I 'went around in circles' so much whilst trying to get back to stock that I can't remember ever step I tried, but it would seem a bit of a coincidence if the hardware failed just around the time of me having issues returning to stock ROM.
Also, If I was to relock the bootloader is it possible to tell that it has been unlocked in the past? It was purchased May 2018 so would still be in the 2yr warranty period but I wondered if Huawei could tell it had been unlocked in the past (I also read somewhere that the warranty is invalidated just by registering to get an unlock code, even if you never actually used it? - not sure how true this is!)
Cheers!
Andy

The touch doesn't always work on A13

Hello everyone
This is the case on Firmware from 11 Mi UI, everything works well (Syberia 10A). I install A13 and Firmware from 12 Mi UI and the touchscreen starts to freak out for me, namely, it does not work when re-locking / unlocking. You have to turn the screen on and off many times to make it work
Is it possible to somehow pull the drivers out of the Firmware 11 and transit them into 12?
