Question about Anti rollback (Mi A2 > Mi 6X) - Xiaomi Mi A2 / 6X Questions & Answers

If I will flash Miui rom that will trigger ARB, I won't be able to go back to Android One rom. Is there any more side effects of triggering ARB?

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.

The touch doesn't always work on A13

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?
