Ok, so a couple months ago, my phone sensors died and after a long time of procrastinating, I decided to try to fix it, I've managed to do it and I'm sharing the fix with you guys, as I didn't found any fix online.
So first, why this happens?
It's because of the phone's persist, that can be corrupted, this can happen if you flash roms, or even with updates, like it was in my case.
How to fix it?
Ok, so first you will need a few things.
Adb and Fastboot
persist.img file (and a couple more files for the flash to work, but I will place a link here)
Xiaomi Miflash (this version will install the drivers, but if don't, uninstall and boot Windows with Driver Signature Enforcement disabled and install it again)
Download All here - it's already modded to flash persist only. It will not wipe your data.
After installing Xiaomi Miflash, you will need to boot the phone in edl mode. You can do this even with you bootloader locked and it will work. To do this, first boot in Fastboot mode (Vol down + Power), plug the USB cable on phone and computer, then open cmd on the folder of fastboot and use the command:
fastboot oem edl
After that, your phone's screen will turn off and the led will keep blinking red.
Now, open Xiaomi Miflash.
Click on Select
Select the folder that you downloaded earlier.
Click refresh, your phone should appear on the list, if don't, reinstall drivers.
Now click flash.
The flashing is quick, and now your phone is fixed.
Any doubts, free feel to ask!

My phone camera laggy, video play laggy, and acceloremeter not working... @FalconMaster
Please help me! I did the flash, it worked correctly! but now you're saying that you have your account and my device is locked! 170 ****** mi account number. there it is reporting that it is linked to your account. please contact me at PM, and help me.
This method is not working for redmi 4x
Please give me persist.img file for redmi 4x for locked device. I tried your given method but it's not working in my device it show file and device does not match
..
sorry for my bad English
Different phones
For everyone with different phones, you need to get to Mi website, download the fastboot ROM for your phone and flash the persist only. This can be done by removing all lines from the xml file, except the one that flashes the persist. After that, flash it normally as in this guide.
Redmi note 5a prime
Hi, is this working on note 5a prime?, When I bought it the only problem is when I use camera, causing some lag, need to open and close again. Also when video recording.
Hello. For the first time I write on this forum and I want first of all to thank all of you for sharing your work and knowledge.

Aa
I cant boot into EDL. So, can i flash it with fastboot. Please help me. Im using mi note 3
Man, I don't really know how that worked for you. Your script erases persist and flashes rpm.mbn to persist, that file isn't even present images folder.
then open cmd on the folder of fastboot...... which folder do u mean ?
i used "C:\XiaoMi\XiaoMiFlash\Source\ThirdParty\Google\Android\fastboot.exe" it detects the device but the phone's screen doesn't turn off and the led isn't blinking red, it stay at the LOGO FASTBOOT ....
i tried to flash it with XiaoMiFlash.. it detects the phone but it errors out...
i have Redmi Note 4 Global Snapdragon Version
Does this method work on custom roms?
Im on Los 15.1 and my gps doesnt work. Will this fix it?
fixed my problem on redmi note 4x
Thank you so much FalconMaster.
it fixed my problem on redmi note 4x (mido).
Thank Thank you very much.
Great guide :good:
So I read everything. Will this method work for my MI 9 global version ? After unlocking the bootloader, I flashed de Android Q beta from the official web page, using MiFlash(I think that's the correct name). So I didn't like the Beta one and downloaded the global stable version, flashed with MiFlash. Everything was perfect, but my Accelerometer and Gyroscope won't work. What do you suggest? Thanks a lot!
Yesterday unfortunately I dropped my phone after that I rooted my device and installed twrp! But now my screen light glows very late after unlocking through fingerprint or unlock button or double tap wake up! Is this problem due to hardware issue or this is due to bugs of software after rooting? Anyone help plz
Yes, it's a bug.
its a hardware problem rooting and installing twrp cannot cause the screen to lightup late. unroot flash stock rom lock bootloader and take phone to service center dont take phone to service center rooted and with twrp and with unlocked bootloader.

How to install :
1. You need to have the bootloader unlocked , and the TWRP installed .

[ THE SOLUTION IS : To boot into TWRP ( volume up and power button ) and from TWRP , tap on Reboot --> System , this will boot the phone normally , currently we can do nothing to solve this :crying: ]
Note : If you come from another ROM , you will need to do an wipe on system , data , cache .
Also please take an backup , if you will want to restore back , or something goes wrong
1. Download the ROM
2. Download and copy the ROM , inside your internal memory
3.With all wipe-Dalvik / ART Cache-System-Cache-Data.
4. Flash the ROM
5. After that you can root
***Suggest to root with Magisk

Updated, thanks for the help..
aserge , maybe make another version of this ROM , there change the default keyboard to gboard , or back to AOSP , restore the default launcher , leave the stock camera ( in case we want to use the original camera , with the camera2api module disabled ) , stock video player , and remove all the added apps
i think that will be welcome :angel:
Thank you very much Aserge for continuing the development. Thank you very much

With the modem 6.0, the standard camera does not work. It does not make sense to return it.

Not interested. This is a step backwards. Soon, a google camera with portrait mode will be introduced. The standard camera is an outsider.
Hello, Can you show me more cleary step by step to install this ROM ? Does this rom install itself the same as Russian? Can I use this manual from page 35
https://forum.xda-developers.com/le-max-2/how-to/leeco-le-max-3-x850-t3584515/page35
Ps.
At my another phone I install Rusian ROM in MAY 2018
Regards
TOM
EDIT:
Now I have a unlock boot loader , but I don't know how I can flash the .zip file or part of extract .
Can I flash it by one command ?
fantastic.. if possible add "multilangiuage".. option/language & imput/ add language
For me... how I CAN get restore a oryginal boot loader ?
Beacuse when I try power on, I will see blinkling green led lighgt. It is no good for me. Simple power ON by TWRP (RESTART system) is hopeless . This ROM in my opinion is very slow. EVERYDAY (from 04.2018) I use RUSIAN ROM by BAIKAL ? IS VERY STABLE AND efficient.

There are only two option for Roms : 1. Is this nougat from aserge ( aka Hero of Labs)
2. An EUI 5.9.021S either by moto , or an more better one , by me , link to that : https://forum.xda-developers.com/le-max-2/how-to/le-max-3-eui-5-9-21s-diamantik-t3834291
Both requiere an unlocked bootloader and an TWRP installed , and there is no fix for blinking green led when powering on .
I mention that in my ROM post
Diamantik Can I back to oryginal Bootloader without blinking power LED ? It is possibile uninstall TWRP ?
Now I want install Rusian ROM By Bajkał ? Sorry but this lock when i try simply switch power on is very annoying.

Well i have not tried yet this , i have not found this very annoying .
I think you can fastboot the ROM , this way the TWRP will be replaced with the stock recovery , but i don't know if this will lock back the bootloader , i suggest you to post in our thread " LeEco Le Max 3, X850 by Generaljan " this question , there will be seen by more , maybe there will be someone who tried to lock back the bootloader , but keep in mind , before doing something ,do some research if don't want an brick , and an minus 30 $ from your pocket for QFIL repair

Many thanks for Your information.
Correct me if I am wrong.
To turn on the phone with TWRP installed and the green LED blinking, I need to:
1 hold the vol up + power button
2. Go to TWRP mode
3. select REBOT
4. select the system
Only then will the phone start the system
do you know a simple method to start the phone?
I will check your ROM tonight
When unlocking the bootloader, I encountered a problem with Critical UNLOCK bootloader = FALSE
Now I know why this problem occurs for some users
I will write this also in the main thread in the evening. Add this information to your step-by-step instructions, your manual helped me a lot
Some links in your guide do not lead to files you write about - it's worth checking.

Well my links was the moto links
i will take a look
If your bootloader is unlocked , and TWRP is flashed , you are ready to try the roms
Well is only a way to boot the phone , volume + and power button , this lead you in TWRP , from there " System " then " restart " and all will be good
There are two roms that you can try my EUI 5.9.021S on 6.0.1 , or the Nougat 7.1.1 EUI6
Also why you don't sell this 4 devices ? And buy yourself something more better
Because i don't think that this x850 will be a developer supported device , better sell this 4 devices that you have , and buy something better , maybe an POCOPHONE F1

As far as I know, it's possible to add a language in the settings.
Updated firmware LeMaX3_EUI_6_by_Hero of Labor_final.
-Updated GoogleCamera (shoots in portrait mode).
-Guilt GooglFoto (for the filming of GoogleCamera in portrait mode in the settings of the developer of the camera to check the box "Use Google Photo".
-Changed the launcher for the native from LeEco.
-Changed the keyboard.
-work of GPS is improved.
After fully customizing the firmware to your liking i strongly advise you to freeze applications from the list of ant07.http://4pda.ru/forum/index.php?s=&showtopic=907872&view=findpost&p=76127861
I don't know what happened bt my phone is rooted and currently running on OOS11 and my fp option is missing at first they said fp calibration not working then i factory reset my phone and then fingerprint enrollment failed ... and now my fp option is missing currently I'm using face unlock i read lot about search lots of forums bt my fp option is still missing
Your persist.img may be corrupt; seems fairly common. There are a couple guides around to potentially fix the issue for this device and if that doesn't work, I'd recommend using EDL Mode to reflash the factory firmware instead of using the on-device restore via recovery mode as I don't believe that will reset/replace persist.img with a working version.

Check out this thread about the fingerprint enrollment issue. You may be able to get your fingerprint back. If not you will have to send it back to OP for the fix.

Can anyone help me please. Recently bought the Find X3 Pro and I've sold my OnePlus 8 Pro on eBay so I was reverting it back to stock and now the fingerprint sensor won't work when I relock the bootloader.
Tried MSM tool to revert back to 11.0.4.4 finger print sensor doesn't work
Unlock the bootloader, works straight away.
Tried upgrading in the OS then locking the bootloader, still doesn't work until I unlock it again.
"Enrollment was not completed"

Could be your persist.img it's pretty well documented here.
Check out the numerous threads that were created.
There were a few solutions with varying levels of success, for the most part it seems people were able to get sorted.
May depend on how you're relocking the bootloader.
If it's via MSM then that may be why.
Samething happened on me too. I just wiped phone data at recovery menu. After relocking. And it's came back.
