K20 Pro compass spins and not calibrates

Hello,
First firmware I was using was Chinese firmware and it worked fine (OTA was updated to 10.3.17). I used it until I got permission to unlock my bootloader. Then every other firmware from Mi or Xiaomi.eu have this problem. I cannot calibrate compass - in compass application or maps app my direction is spinning all the time counter-clockwise. Spin speed is ~5 spins in 3 second. Tried to clean compass app cache - do not help.
Tried to test sensors - in "all specs" click 5 times on Kernel and enter CIT. Result - Accelerometer looks working fine, Gyroscope - Z axis shows -7 all time, Magnetic sensor - spins counter-clockwise all the time.
My bad I have formatted all system before flashing firmware, that may get lost of original "persist" and "vendor" images if they are required.
Summary - looks like gyroscope sensor is failured - Z axis shows -7 rad/s all the time and that makes some functions hardly usable. Compass included.
Phone did not had any drops all the time. Only magnetic car holder was used, but cannot remember it happened same day. It was used with previous phone too and it still worksfine.
I have tried many Cn stable Roms, Indian roms, EEA, Xiaomi.eu. Installing in fastboot mode. No one firmware works fine with compass application.
Several fastboots tried:
Code:
raphael_eea_global_images_V10.3.1.0.PFKEUXM_20190723.0000.00_9.0_eea
raphael_images_V10.3.6.0.PFKCNXM_20190516.0000.00_9.0_cn
raphael_images_V10.3.8.0.PFKCNXM_20190601.0000.00_9.0_cn
raphaelin_in_global_images_V10.3.3.0.PFKINXM_20190711.0000.00_9.0_in
raphaels_images_V10.4.1.0.PFKCNXM_20190827.0000.00_9.0_cn
Recovery ROMs tried:
Code:
xiaomi.eu_multi_HMK20ProMI9TPro_V10.3.17.0.PFKCNXM_v10-9.zip
xiaomi.eu_multi_HMK20ProMI9TPro_V10.4.4.0.QFKCNXM_v10-10.zip
Maybe you can suggest any possibility to fix this? I assume that should be software issue.

Did you ever flashed Q or Downgraded from Q to P?

Originally was Android 9. My first ROM flashed was Xiaomi.eu V10.4.4.0 - Android Q. Later tried Android 9 and Android 10.
I have just tried to install Lineage ROM over Stable CN 10.3.17 ROM - it misses compass app, but random app from net shows that compass works good. I mage a backup of all partitions. Maybe it is possible to restore some partition over working Xiaomi.eu ROM to keep Miui working and make compass work too?

Like others, most probably you broke your device sensors while downgrading. Do a clean restore of Android Pie with a fastboot image. Extract the persist.img from the fastboot package and flash it to the persist partition through LR TWRP. Reboot and Calibrate your front Camera and let other sensors Calibrate aswell. Do a hardware test (*#*#64663#*#*) and you should be able to see values for x,y,z axis for most of the sensors. If the compass still doesn't work, you might have a defective item.

Redmi K20 Pro persist backup required
I have tried steps you suggested and works everything except Gyroscope. As before. I have made testing using Sensors Multitool. Rotation vector Z is swinging from -1 to 1 all the time even if phone is still. Gyroscope info shows Z axis always -7 or more. Gravity reacts to movement, but unnatural. On Q everything worked until downgraded back to P.
I have found useful topic about this problem - https://forum.xda-developers.com/pixel-3-xl/how-to/android-10-sensors-bug-t3964904 . Reading through maybe will find something useful for my phone. I have never rooted my phone. Used Magisk few times. Persist.img I used was from Android 9 Chinese ROM 10.3.16 (As my phone is Chinese version). Persist.img was installed only with TWRP, it showed no problem when processed it.
Maybe someone can share backed up persist partition of Redmi K20 Chinese version? Hardware version in "All specs" page shows "Hardware version: V1". I got instruction to retrieve it. The following should put an image of the persist partition on the phone's internal storage. It should be executed on TWRP from Advanced > Terminal window.
Code:
dd if=/dev/block/by-name/persist of=/sdcard/persist_backup.img
I have made md5 checksums of all persist.img I have in each firmware. Despite file size is same, content each time is different.

User which requires sensors fix should do following:
1) Open root shell
2) dd if=/dev/block/by-name/persist of=/sdcard/persist_backup.img
3) Copy new persist.img to your sdcard home directory
4) dd if=/sdcard/persist.img of=/dev/block/by-name/persist
5) Reboot device

So, maybe someone with K20 Pro CN version can share their persist.img file with me and others?

Hey, I have the same problem and this is getting me crazy. Have you solved the problem?

No, I got tired trying and now use phone with this problem. I get to much effort live without my new phone as I need on my daily life. Lineage os is not interesting to me too use for working sensors but without miui.

hmmm i am seeing a pattern , where many had problems after flashing roms , odd , anyway how to tell needle on the app is really facing north ?

It occurs also on my Mi 9T Pro with official global ROM... Compass spins constantly over Z-axis. It is especially visible for instance in Google Maps and annoys a lot. I think I will wait till MIUI 11 release and then maybe return this phone unless it will recover.

Yes, looks like it occurs with officials ROM too if ROM was uploaded by FASTBOOT mode. Stock sensor settings gets rewritten with universal settings which do not work as desired.

Yes it seems so. The worst thing is that, it was working just fine at the very beginning, compass was lost just few weeks after I bought the phone
In the meantime maybe there were two official OTA updates, nevertheless I cannot recall what could cause loss of this functionality.
Thanks for your comment anyway.

Even mine was screwed up..I taught I'll have to take it to service centre ....I had formatted system ...and when I installed fastbiit ROM..the gyroscope and accelerometer was not working.. unfortunately I had relocked my bootloader and had to wait for 30 days to flash persist file....so I just gave factory reset from settings a try..and it worked

You did factory reset from ROM version you have uploaded via FASTBOOT earlier and that worked? What persist file you have used? And how compass functionality - works? Fastboot ROM version accelerometer works fine, but compass fails.

At first my gyroscope also wasn't working....I didn't flash any persist file but now I can see that the compass is buggy... And also the video recording is buggy.... Hope after flashing miui 11 upcoming update it fixes things

I have the same issue. Don't know how to fix it. Am already using miui 11

Touchscreen Dont Work after Update to android 10

Hi everyone
I Update my MI 9 Global to android 10 ( MIUI 11.0.6 Stable QFAMIXM) but after setup finish and phone rebooted the touch screen dont work any more.
one month ago my phone touchscreen broke and replaced and worked great before update (android 9 on MIUI 10.2 I think )
but after update it does not react at all . i installed custom recover twrp and installed new rom from xiaomi.eu but nothing changed. :crying:
I connect optical mouse throw otg cable to phone and every thing works normal. sound , network , wifi , bluetooth , camera , .... all work great but touch screen doesnt respond .
I think the problem is kernel dont load driver for touchscreen properly or the new android dont load firmware for touchscreen.
it is dmesg output :
https://pastebin.com/i4Cfyden
if you look at dmesg log you can see some line with error like :
"Firmware in the chip different from the one that was burn! " and "fts_fw_update: firmware update failed again! ERROR 82080B02"
please help me to solve this problem . if I have to use custom kernel or change and compile the driver for new touchscreen ??

based on dmesg log (Read FW from BIN file st_fts_f1.ftb !) firmware must be in file "st_fts_f1.ftb" but I cant find this file in phone memory. I have root access to phone and searched all folder ( including vendor and persist partitions )

Just flash the previous Android version that worked. It sounds as if you bought an aftermarket screen with different hardware.

I Installed android 10 GSI Rom from https://github.com/phhusson/treble_experimentations and touch screen and finger print sensor start to work !!
but GSI have some problem and limitation for mi 9 for example battery is not so good and full screen gusttures dont work. how is possible touch screen works with this rom but not by official Android 10 ?? If i can use some part of GSI with Official or Xaiomi.eu roms to enable touch screen ?

Maybe pocket mode is interfering on stock ROM?
Try a old stock Chinese ROM?
Start from very old..

How Can I test that ? And yes all android 9 ( official or xiaomi.eu ) work but have some minor finger print problem . But The only Android 10 that has not problem with touch screen is GSI rom even GSI v220 ( based on android 10 ) works . I dont know how this is possible ? I based On this I am sure the problem is software not hardware . A question Sir : If touch screen driver in Kernel (boot.img) or in vendor ? I think If I can merge vendors or kernel from android 9 with system and other from android 10 the problem is solved. Thank you and Please any Of your help and info can solve the problem

I have the same problem, Mi9 running MIUI10 Global, want to upgrade to MIUI11 but after update the touchscreen doesn't work, only via otg USB mouse. Tried to flash MIUI12 ia TWRP, again touchscreen doesn't work.
Have you solved the problem?

Same problem
Guys, has anyone managed to solve this problem?
Mi 9 After changing the screen the touch locks after a few minutes of use
My Mi 9's screen broke and I had to change it, but after a few minutes of use the touch simply stops working.
It happens a lot when I lock the screen, and I try to unlock it after a while.
Guys, I've been looking for the solution for some time but I just don't think so. I even found some forums saying to downgrade to version V10 but I still have this problem.
The screen is original, imported from CHINA and is of high quality.
Has anyone had this problem and can share the solution?

unfortunately i dont find any solution yet. and i think no one is kind enough to help us . Now I am sure it is kernel problem. i installed GSI android 10 on android 9 vendor and touch screen works great ( but have some other problem with GIS like cant recieve or send sms messages) So the problem Is kernel used in android 10 . even i installed Quantic-Kernel on aosp and after that again touch screen stop working.Please if any senior member who is familiar with android kernel help us to compile or change touch screen driver used in version 9 and solve the problem . Please Please

You can install new Rom and see if the problem gone or no . I recommentd you install new stock android 10 with MIUI 12 or xiaomi.eu rom .
If after new install problem exist it may be some hardware problem . Even before install new rom you can reset factory your phone and see what happens ( backup up your data before reset factory)

MI9T PRO Screen Replacement Problem

Mi9T Pro screen died after a small drop. (green line then followed by death.)
Went to service center to replace the screen, while testing new screen every time I entered the password it reset.
Has anyone experienced this issue before? What can I do to solve it? The phone was in 100% working condition prior to the panel dying.

Its fault of the fingerprint do a reset and dont configure fingerprint , I think the new screen isnt an original one, and miui 12 vendor have a problem that if you use fingerprint reboot the phone.

Yeah, it's very possible it's not an original screen. I'm in Cambodia and there's only 1 official vendor, who never had stock. Unofficial vendor is a big repair chain that sells it as original for $90, but very possible it's chinese copy.
I am on MIUI 12 EU stable. When it reset, I used pattern unlock.
EDIT:
It is the MIUI 12 vendor file. If I use miui11 no issue. If i use miui12, if i setup fingerprint it will reset phone.
Do you suggest a factory reset? I was hoping to avoid that. I'm also gonna try flashing PassReset to remove lock screen and see if it continues.

Hi, I am also facing same problem. I had my screen replaced by a local shop and quoted me $70 for an original replacement screen, but now the phone reboot after entering the password. Did factory reset help?

Question Camera won't focus

Hey everyone. I'm hoping you can help me out
I have a mi 11 running 12.5
The main camera will not focus on it.
I had this problem before, and doing a reset fixed it, but now it is permanently not focusing.
I don't know if I'm SOL or if there is something that can be done
Even if I try manual focusing it doesn't do anything

Try to download" MIUI hidden settings" in AppStore
With that u can calibrate ur camera

On mine calibration always failed

Try to wipe the cache of the camera app

If you can, just try other rom like MIUI dev version or MIUI eu.
Or just flash latest MIUI rom again via fastboot and pray for good luck.

Try using the original cable that came with the Mi 11 and avoid plugging it into usb hubs

I remember i had once this issue with my pixel 3. i just dropped my phone on a book for not damaged it, it was my lens that was blocked.

That seems to have done it
Now to wait 3 more days before I can unlock
I can't seem to find a stock 12.5 chinese rom on the MIUI site to try flashing through Fastboot

Not needed. I came from Global and a friend from EEA ROM and both work fine. Just don't re-do the procedure again before the timer runs out, otherwise you need to wait again.
Just wait for the timer to run out, unlock your phone and use the latest fastboot-ROM from Xiaomi.eu

Welp... finally got the bootloader unlocked, flashed back to 12.0 instead of 12.5 and it's still borked
Guess it's time to throw this on eBay and see what I can get with a wonky camera

Question MI 11 ULTRA Random Restarts - Reboots

Hello dear community,
I have a problem with my Mi 11 Ultra, I been having a issue where my phone restarts randomly. (It can happen at any time, I can be on Youtube, Whatsapp, Maps, Idle, etc and the phone will suddenly flash a green screen and restart. Heavy use or light use, I cant detect a pattern .....)
I been having this Issue 2 month after I bought this phone with CHINA ROM MIUI 13
after that 2 months the restarts appeared.... (can´t remember if there was a System update or something but from April 2022 to May 2022 the phone was working excellent)
I have read that MIUI 13 in other POCO and Xiaomi Phones have the same behavior.. but cant find any solution for MI 11 ULTRA
What I have tried with no positive result:
(Wipe everything with TWRP, all the options,cache,data,interna,etc.)
Install STABLE MIUI EU ROM - Clean Install
Install Weekly MIUI EU ROM - Clean Install
Update Security app - Latest Version in APK Mirror
Delete Cache security app
Today I tried to install Global with MiFlash Tool but mi flash anti rollback check error occurred ;( (Don't know how to solve this...)
Do you think I have a defective Phone with bad Motherboard?
This is very frustrating and at this point I dont know if should buy a Xiaomi Phone again....
Any Help will be appreciated

Hi, i believe you are facing the issue when you are on wifi i am also facing same problem, when on mobile data there is no problem, can u confirm if its same? Wifi problem

in my case It happens on WiFi and mobile Data.

U can flash using platform tools to get rid of antiroll back, search for tutorial in YouTube, try miui 12.5

Global same issue..
Maybe a bad Motherboard?

So yesterday I Flashed OEM CN Rom, update with OTA and the problem persisted...
Then read about issues with restarts and Location Services in MIUI.
I Installed MIUI_EU Latest BETA ROM and deactivated location.
Right now I haven't experienced a single restart. Tomorrow I will activate location to see if the problem persists or maybe the update solved the problem.

Did anyone find a solution?
I bought mine on aliexpress and I have the same problem. It crashes and restarts numerous times a day.

Unlock bootloader and install global MIUI 13.0.4.
Very stable , no crashes/restarts.

the bootloader is unlocked. do i install the rom via fastboot or TWRP?

Both method should be fine .
If using TWRP , use format data option first, else system won't boot up.
If using Miflash use clean all but make sure don't use the lock option.

No, maybe is a motherboard issue. I bought this phone from giztop. I think I will return it and get my money back. I will never buy Xiaomi sh**** again.

in the first 24 hours yes. it was working perfect.
Then it started to restart and crash.
without solution.

I am having the same issue....
Please look in the /root/data/vendor/ramdump folder.
I am having lots of ramdumps eating space.

So just received the phone yesterday after sending it for repair to Xiaomi All the way back to China... And this piece of trash phone still rebooting.... Never buying again a phone from this trash company... Also Giztop is so unprofessional because they didn't solved the issue ... They told me that the phone was on perfect condition and they weren't able to solve it. Thanks to them I also had to pay 250usd of taxes because they send it like if it was a new unit... Give yourself a favor and don't buy from Giztopz, they send defective phones.

Try disabling the RAM extension feature.
Or try a custom rom like EvolutionX or CrDroid.
