Hi all. I have unlock the bootloader and downloaded the ROM for my Mix 4 ... but the installation scripts are missing after unpacking. I have ticked Unblock, Apply and Save and have downloaded the files multiple times. Disabled SmartScreen, change setting in Group policy in Win10 but still not working. Any help here is appreciated.

After flashing the ROM and logging in .. Google is informing that Pixel 2 has logged in. Hmmm .. I thought I got hacked but signing out and back in again, it's still Pixel 2 and Google sent a Welcome to the Pixel Family email .. lol.

Hello. Got my Mi MIX 4 yesterday and currently on latest china stable rom. Having issues with notifications being delayed and sometimes just shows up when I open the app itself. Setting Auto start on and removing battery restrictions doesn't help either.

Does this rom fix those issues? Currently waiting for days to unlock bootloader.

I just flashed the EU rom and rooted. I am having trouble with missing Discord notifications in particular. Other apps have no issues with notifications. Wondering if anyone else has similar issues with me. I enabled auto start and disabled battery restrictions as well.

    I'm having problems installing the latest 12.5.9 xiaomi.eu rom to Mix 4 using TWRP. Have tried two versions of TWRP (mifirm.net and unofficial Twrp) and neither lets me install latest mix 4 stable ROM . I flashed TWRP, wiped the phone, format(yes), and adb push the zip file to the /data/ partition but when I run the rom zip in TWRP I always get an error. Not sure if this is relevant but even though I have done a format, when it fails and if I reboot to system, it re-installs the weekly version rom I had on it previously I've done this process dozens of times before but have I done something wrong this time? Any help would be great! Pictures of error attached.

    Your problem was caused by an old update-binary that doesn't support the EROFS filesystem of MIX 4. The attached file has been extracted from one of the Project-ICE builds. Download and unzip it, replace xiaomi.eu_multi_MIX4_V12.5.9.0.RKMCNXM_v12-11.zip\META-INF\com\google\android\update-binary with the one. And then recompress, flash it.

    So literally just unzip it and rezip it nothing else?
    Aye. Just uncheck ZIP signature verification (if checked), since the ZIP will be unsigned (if you don't sign it yourself after recompression).
