How to fix sensors?

I Flashed Mi 6x rom in my Mi a2. I dont know what happened.
The camera was staying black screen. I flash stock rom to fix. But come problem. The stock rom not fix the issue.
I discovered all my sensors no enable.
How to fix this? What i can do?

I have this problem now. Did you ever find a solution?

If you are allready converted to 6X and have TWRP do this:
-boot to TWRP
-connect your phone to PC and copy persist.img from stock MIUI 9 ROM used to convert to A2 to 6X
-In TWRP go to Install, then Intall Image, navigate to your persist.img and Select Partition to Flash Image: Persist
-After flash, reboot to System and now your all sensors should work
I have attached persist.img so You can use this one...

Is fingerprint fast as original? Because I convert a2 to 6x but the fingerprint sensor was very slow.

FP sensor is working perfectly, precise, fast, face unlock instantly also. I am curently on MIUI 10 latest from xiaomi.eu and everything is fast and fluid.

Thank you i think it worked.

Guys, I can't solve the problem using this method with Mi 6x on MIUI 11, it only works on MIUI 10. I searched persist.img on rom MIUI 11 beta but I couldn't find it. How do I solve this problem using MIUI 11?

after i got miui 10 i sticked with it until miui 11 was launched, i just upgraded it and all still worked good!!! now im currently using pixelexperience 10, all is still good, i never again touched the persist

I am also using Pixel Experience 10 and I am no longer with this problem. PE already comes with API2 enabled, so I don't think it corrupts the persist partition.

My first encounter with bootloops and a nearly bricked device

Before we start, I am on an unlocked boot loader with Stock EU rom along with twrp/magisk installed.
So I went ahead and downloaded the latest full rom from c.mi.com and proceded to flash it via twrp, but before that, I made a nandroid backup just for safekeeping. Everything went well but when I tried to install magisk it gave me cannot mount system error. So i tried restarting Twrp but the whole storage was now encrypted even though I took of pin/password from the previous MiUi version. So I googled a bit and tried different Twrp version but none of them even booted but the original version so I gave up and just restored the nandroid backup and this is where the boot loop problem started.
In the end, I went ahead and flashed the whole thing using miflash which went smoothly but not without me being utterly depressed the whole time thinking that I might have hard bricked my device.
Is there any way I can avoid all this headache in the future when Miui 11 and android Q comes out cause I am pretty scared to even try to flash anything atm.

You need to wipe data after flashing TWRP otherwise you won't boot and also the phone will restore the stock recovery on reboot if you don't flash dm_verity
Check this post of mine it might help.

The problem was that no matter what recovery(apart from one) I tried including Orange fox, after flashing them via fastboot I always ended up being stuck at Mi logo ( even tried fastboot reboot recovery command)

Do you have the Mi 9T Pro?
If you have, only latest orangefox 1.0.0.7 or Mauronofrio's TWRP working for this device. Abhisheks or LR TWRP doesn't work on Mi 9T Pro.

Yup Mi9t Pro user here, and yea for me only latest Mauronofrio's twrp works, but not sure if it will work with Miui11/Q when it is released sometime today
Just googled the orangafox recovery you mentioned, is the one with OrangeFox-R10.0_7-Stable-raphael name?

I think it will work. Because I'm on indian Q Firmware with LOS 17 and there was no issue with Mauronofrio's TWRP.
Yes that's the right orangefox version. I didn't remember the exact name. I tried it once but went again back to TWRP because i grew up with it. :laugh:

Thanks for the info regarging Twrp. everything will go smoothly this time hopefully.
I also wanted to ask that did you format data after installing twrp via fastboot? I was reading on Twrp thread that if you get encrypted after flashing twrp then you will have to format all data for it to disable encryption. This is the only thing that I am still confused about and I really dont want to format my internal storage again . Can you maybe list steps that you took to upgrade to Android Q? thanks

I have Mi 9T pro like you and flashed Orangefox recovery version _07 and no problem at all, i also flashed disable_dm_verity just to be safe and i believe this is where people get stuck on mi logo, if you flash this file it blocks your system from restoring the stock recovery on reboot and makes your TWRP/Orangefox permanent.

Flashing Mi 9t Pro global to K20 Pro india - missmatching error

Hello,
I unlocked the bootloader and I am trying to flash the india k20 pro rom with miflash but I am getting missmatching image and device error .

few days back i ran into similar problem
my device is raphalein (K20 PRO INDIAN)
and i flashed miui 11.0.2 China FASTBOOT Rom.
later when i tried to install Indian FASTBOOT ROM
it said device and vendor missmatch in MI flash.
i fixed this problem by firstly flashing RECOVERY orangefox( its an entire process so...do it carefully)
than wiped everything , DATA ,CACH, SYSTEM, DALVIK CACHE, VENDOR
and then flash this https://downloads.akhilnarang.me/MI...al-V11.0.1.0.QFKINXM-10.0-vendor-firmware.zip
and now u can flash FASTBOOT LATEST INDIAN ROM.
hope it will fix it.

I am trying to boot the device with global rom now but it is just stuck in miflash for 30min, how long it should take?

There was an easy solution to this. All you had to do is change a couple of lines in the installation script and flash it with Mi flashtool. I also got the error and did a simple Google search and figured it out.

[SOLVED] Issues after MIUI 11 to MIUI 10 Downgrade on K20 Pro

Hi All,
I unlocked bootloader and was able to successfully flash Fastboot v10.3.3 ROM of my region (India) using MI flash tool. After flash front camera stopped working and phone was asking to calibrate but was failing to do so. Then I did OTA v10.3.5 upgrade and the camera issue was not more present. But there are some issues which are very irritating:
1. Gyroscope wont work in PUBGM. Previously it was working in MIUI 11 but since downgrade it is not working (both 10.3.3 and 10.3.5 versions). I checked the gyroscope values using CIT tool and there seems to be no issue. In PUBGM crosshair moves on its own in any random direction, sometimes it moves towards ground and sometimes it moves left slowly. Even VR videos are no longer working.
2. Camera app video recording is very laggy. The recording process and recorded video are very laggy (5-10 frames per second) using default setting.
Other sensors are working fine like compass, GPS and accelerometer(phone UI rotation is working fine).
Kindly help me please.

Ok thanks, I will do a fresh flash of v10.3.5 through MIFlash and then boot into TWRP and write persist.img.
Is it possible to boot temporarily like following?

in order to write persist.img

Don't do this please .
From what I know your phone is L1 widevine certified. If you flash persist img from fastboot rom You will lost L1 and downgrade to L3.This will affect your resolution in Netflix and others !!!

Thanks, I didnt do it. I was able to do an OTA update to MIUI 11 and everything seems to be working fine now.

All the sensors i.e gyroscope accelerometer etc are disabled in Mi A2.

I am not having any sensors on my Mi A2. I tried Xposed too but the problem is still not solved. I had also flashed my Mi A2 with Mi flash tool but no results;(

dont worry bro just do a clean flash of the lates update and you should be good to go and everything will be ok or else just flash the vendor.img then everything will be fine and ok
