We have 3 Mi8's in our house, i just finished setting up the 3rd with this rom. We have absolutely no issues on any of our Mi8's. Many of the people on this thread have no issues. Most all of my friends with Mi8's on XDA have no issues.
If you are having an issue it is due to something that you did, most likely corruption or a permissions issue. here is where people get confused. What does a Clean install mean to you? Most people think that it means wipe, many of those people wipe too much. Such as system or persist.....this happens a lot, when people hurry to install and skip the instructions.
If you were previously using the last Xiaomi.EU build, I am guessing that maybe your were you the hack stereo mod, there is no need to use that since this rom already uses a stereo effect using convolution reverb.
Here are some steps that should guarantee a working install. Maybe a little bit overkill, but at the end of the day, will probably save you a lot of time
1. Do a full clean wipe , which means format Data, type yes, then reboot to recovery, then go to Wipe and swipe. if this is successful proceed. if it fails you have partition corruption and will need to restore using the flashall.bat method.
2. Assuming that you could wipe data, reboot phone to fastboot and flash miui_MI8Global_V10.3.5.0.PEAMIXM_db02d24cf1_9.0 via adb ( if you have a global device, otherwise use the latest fastboot rom for the china Mi8 device.) This will restore any corrupted partitions. - Alternatively you could unpack the rom twice and use the flashall.bat method with the phone connect and in fastboot mode.
3. After successful flash, install Twrp following the instruction available on this site for rom installation.
4. After you have successfully install rom and TWRP, you have two choices. Setup and make a full TWRP backup so that in the future you can avoid doing these steps again or Go to step 5
5. Go to wipe, swipe to factory reset, then install xiaomi.eu_multi_MI8_9.10.11_v11-10
Now setup, you should have no issues.
Do not install Magisk until you have setup the phone, do not install mods such as xposed or gimmicky stereo mods. Enjoy.
