Problem with call recorder in 12.5.2 ROM


Jan 8, 2022
Hi, I recently installed the ROM V12.5.2 from to be able to use the Xiaomi calls and messages app and be able to record the calls, my Xiaomi is a Redmi Note 8T and the Indonesian ROM is not available, so I had to install this unofficial from So far everything is ok but the calling application gives me an error when it is about to record the calls and although the call continues it does not record it and when hanging up it says that the calls app has failed and has to be closed, below I attach the report of Errors for what it's worth, I already tried updating the contacts and phone apps and the recording one but nothing, if someone can help me I'll be very grateful since recording the calls was the main objective of installing this ROM and I can't do. Thanks

Also... I have long weekend.
I tested the downgrade, but is not ok.
I tried format data and install the older rom (xiaomi.eu_multi_HMNote8T_V12.0.1.0 xiaomi.eu_multi_HMNote8T_V12.0.2.0,) , but not working the call record.
I tried total clean install with mi flash tool, and i installed stock rom, I reopened bootloader, installed twrp installed xiaomi.eu_multi_HMNote8T_V12.0.1.0 was recovery loop, installed xiaomi.eu_multi_HMNote8T_V12.0.2.0 was OK, but call record same problem with 12.5. Is it possible, can't not realy downgrade???

Hi Everybody!
If somebody want downgrade from rom from (12.2, 12.3, 12.5) and enjoy the call recorder... I maked this.... (Make your own Risk!!!)
What you need:
- MiFlashTool:
- ROM: (tgz version)
- rom:
- Boot unlock:
- twrp: (work with willow)
- adb tool (for your OS)
- repair for contacts and caller search by dark mode (I not found the original link, that is my upload from year 2020, but it is working):

1, Make full backup!
2, wipe cache, dalvik, system, vendor, data
3, Reboot fastboot, use the MiFlashTool and flash the V11.0.11.0.PCXEUXM.tgz file (ofcourse you have uncompress)
4, If flash ready, restart in the fastboot
5, Start the mi-flash-unlock and unlock the bootloader
6, Boot the system, after the start, enable usb debugging
7, reboot fastboot and flash the twrp from adb
8, reboot twrp
9, from twrp flash rom (HMNote8T_V12.0.1.0.QCXMIXM_v12-10)
10, Root if you want
11, Flash the repair for contacts and caller search by dark mode
12, enjoy
