The touch doesn't always work on A13 - Xiaomi Mi 9 Questions & Answers

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?

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

Changing original Xiaomi Mi Max 2 to a custom rom

I have an original Xiaomi Mi Max 2 (Android Version: 7.1.1, Build: NMF26F) with all the Xiaomi updates. Since the phone doesn't get updates anymore, I am looking for a solution to get a custom rom with security updates.
I am searching for a custom rom too, which does not need GPS for Wifi-SSID. With my mi Mi Max 3 and Android 10, GPS (saving doesn't exist anymore) GPS must be activated to see the SSID and I am forced to use LTE, while I want 2G (setting is lost after a restart)
So maybe a ROM based on Android 9 makes sense?
Please point me to a link how to "open" the original phone, so I can flash a custom rom. Does the official way work with the Max2? I have a very old PC, but with Windows 10 20H2 for flashing, normally I use a linux pc.
I am happy if you can help me how to start.
First,TWRP.
Then,https://androidfilehost.com/?w=files&flid=315788 for warm up.

Redmi Note 9 bootloop after restarting for the installation the last update, not rebooting to fastboot either

I need dire help . I just downloaded the new MIUI 13 update and rebooted to install it but it went into a bootloop instead.. It's not rebooting into fastboot either.
Never download MIUI updates right after they get released. My Redmi Note 9 (EEA) also got bricked, but on the 12.5 release. I had to send a complaint to the shop where I bought it from and they have reflashed my whole phone, thus losing all my data like authenticator codes and 80 GB of photos and videos with my family. And this is a Mediatek chipset which is very common to get the phone bricked on. Always wait for at least the first patch before updating anything, or just don't update and stick with the already buggy environment.

Question Fix Xiaomi mi 11 - Speaker not working

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.

Mi 8 Lite Bootloop.... ANY HELP APPRECIATED

Hi all,
I have a Xiaomi Mi 8 lite (China ROM). Before Xiaomi disabled Google services entirely on the new miui versions, I had installed them myself as they are not pre installed. However, after miui 12.5.1 they stopped working (and without knowing they had effectively blocked Google services from being installed on China ROMs) I thought the version I installed had become outdated and hence stopped working. I deleted some Google service frameworks and was going to reinstall newer versions but then after a while the phone turned off and is in a Bootloop now. It doesn't get past the miui logo when turning on. Unfortunately I haven't unlocked the bootloader or enabled usb debugging (lesson learned ) - is there any way I can either reflash a stock/custom ROM and/or recover my data?
Thanks to anyone who replies to this post and am happy to send photos of the phone if needed
It's fine after wiping data 3x from recovery 3.0 it came out of the bootloop after 30 mins
