One more question. What camera app should I use if I want to make full use of the 3 cameras on the back? I used ANX in Android 11, but they don't support Android 12 (yet?). Another one I used was a GCam mod, but I don't think that one is available on Android 12 either.

I use also this one:

Both working very well on Mi9 with A12 ROM. Use the related configs for each cam.

TWRP can't handle encrypted A12 ROMs at the moment. But you can try PE Recovery. It's available on their homepage.
Hmm, so I'm using PE right now, but I don't think it's able to decrypt either. I'm unable to 'Apply update', I can only use ADB to apply updates. When I try to apply updates using adb sideload I get an error saying 'Mount failed data!'

Edit: I'm really confused. It appears that decryption _is_ working, because I just installed a crDroid update using the updater.

Thanks buddy.
To change the recovery I only have to flash the IMG file in TWRP, right?
Anyway I think I'll stop updating until there'll be a proper recovery which can decrypt data
I would just follow the installation instructions, worked for me

Also, PE decrypts just fine apparently. Just did an update using the crDroid updater

When I reach the third step it says that the Hey Google feature is unavailable on this device. Is there a way to find out why this is the case?

Maybe it's a silly question but, there is a way to change the enormous awful clock on the lockscreen?
Customize it, make it smaller, just like in android 11.

Yup, just did the OTA, the script runs, then no boot and not able to access to SDCARD etc...
You have to install manually from TWRP, as instructions says, not do the OTA I guess !

    hey guys, I need some help.. I updated my mi9 from CrDroid 8.5 to 8.6 from the notification and the device is now stuck in a bootloop

    I already tried the PE recovery method and it's still unable to boot.. any advice?
    Is your device currently encrypted or not?
    Switching between encrypted and unencrypted requires formating data (resulting in loosing all data)
    Using PE Recovery usually means that it is encrypted.
    If you flash TWRP and you can browse your files, it is not encrypted.

    If it is not encrypted or your are unsure try to flash DFE.
    You may also need to reflash gapps?

    Sorry for the late reply, the issue was solved after reflashing nikgapps

    @sklaes it is encrypted and I do not intend to flash DFE for increased security but its a pain to not be able to use decryption on twrp for now..
    Did you flash gapps? I was also stuck and that helped.
    @manxmsnn and @sklaes, thanks for the tip!

    Also, @raystef66 thank you so much for your work in maintaining this rom, it has brought new life to my mi9!
