My gyroscope, accelerometer, compass and camera autofocus not working!!!

DragonSlayer7# · Jun 18, 2020

So I was using PixelExperiece ROM and decided to switch back to MIUI. I downloaded latest fastboot ROM from MIUI website, Flashed it using MI FLash Tool.
While flashing my phone displayed "System has been destroyed" in between. And MIFlash tool showed some error.
So, I tried flashing again and MIFlash tool now said Bootloader was locked. (Because lock_all_and_install was selected previously).
Therefore I downloaded MI Bootloader unlock tool. (The phone still shows "System has been destroyed"). Ignoring that warning, I went to fastboot and ran unlocker. To my surprise, after unlocking was complete and phone restarted it booted into MIUI. I thought "System has been destroyed" problem would be solved. But later I realised, my camera was not focusing on close range object. It wasnt focusing at all. Then after playing around to check everything I found out, my camera was not focusing, gyro was not working (No auto rotate and noting in CIT test) neither was my compass working. So there is some kind of problem with my hardware now.

Later I tried flashing same fastboot ROM again hoping it will install fully now and not ending up in "System has been destroyed" error. And I also chose option to not lock bootloader while flashing in MI Flash tool. This time the phone did started on to MIUI but in MI Flash tool it kept showing flashing as status. Even after I disconnected my phone USB cable it said flashing. And those hardware things are still not working.

While using PixelExperience I did changed SELinux mode to make ANXCamera work. Would it (SELinux mode) be a problem for hardware not working? Or is there any other problem?

Thanks in advance for any help.

Wait what u said u flashed recovery rom via mi flash ? U have to flash persist.img (u will find this in your fastboot rom) from custom recovery in system/persist partition. Thats it.

Im sorry, my mistake. I flased fastboot ROM only. Not recovery. MIFlash tool won't allow you to flash recovery ROM at all.

Mmmm... No need to worry extract persist.img from fastboot rom folder and flash via OF recovery in system/persist partition. Then boot u get all your sensors back.

Instead of fixing existing sensors, flashing persist.img screwed up my wifi and hotspot. After flashing whole fastboot ROM againg they are now working. But other sensors are still not working.

Really? I mean i used same method last time for my sensors to work again and that worked for me. Next workaround is u should clean flash miui 10 fastboot rom then update to miui 11 using updater app. Hope it should work for u.

Can you please little explain how to do it. Step by step method explanation will be much appriciated !! (only installation part, i have all required software and ROM ready for fastboot) I am just not clear how fix my sensors.

Well i just got to know that by flashing 'persist.img' from a recovery will void Widevine L1 certification (Netflix with no HD, also other HD content streaming platform that requires Widevine L1 certification). I heard it will be permanent warrenty void and i don't know it can be fixed or not.

This persist.img thing might work for you or might not.
The full proof way is to reinstall Pixel Experience (Android 10) so that you get your sensors up and running again, then flash MIUI 10 and upgrade to MIUI 11 using system updater app.

Its fine. Just install Netflix from ApkMirror (not from Google Play) and it should work.

Also if you are coming back to MIUI, use this method...

I think you should try reflashing the stock firmware using the Mi Flash and select wipe data option.

Fastboot ROM using MIFlashTool

I got all the sensors back again, everything working fine.
Here is what is did (using PC):
1) i installed Pixek Experience ROM (Android 10) using ADB Fastboot method.
Pros: Every sensors started to work, back to normal.
Cons: None i noticed.
2) Then i turn off the phone and entered into fastboot mode
3) I flashed MIUI 10 fastboot ROM using MIFlash Tool. Though i didn't get the "Success" message on MIFlash Tool but phone booted itself (did show MIUI 10 during boot up, and Set Up screen was appearing) so i assumed flashing was complete. Then i unplugged phone from USB cable.
After setup,
Pros: Every sensors was working perfectly fine.
Cons: None i noticed.
4) i updated from MIUI 10 to MIUI 11 using System update on phone. Now i am on MIUI 11 and everything works FINE!!

So what i found is there is some problem with MIUI 11 fastboot ROM itself. Directly flashing MIUI 11 fastboot ROM is the reason sensors stops working!!

Yes, its kernel problem. It happens if you are flashing MIUI 11 based on Android Pie from any AOSP based ROM running Android 10.
