Dirty flashing via ADB sideload from Arrow 11 is perfectly fine.
Battery usage is amazing, Its more than 2 days for me.

Hi and big thanks. Today i installed your ROM via instruction and everything look working good.
NFC Google Pay pass in default and Play is certified. BT and GCam 8.1 working too.
I am very satisfied! And A12 UI is very nice for me.
(Magisk i don´t need try, because Google Pay working without fixes.)

Dirty flashed from Arrow 11 and seems to work great so far. Audio issues I had whenever I receive a notification while playing videos seems to be fixed as well. Thanks! @Dobsgw
When you have time, clean flash. It will fix any potential bugs. I had issues until I finally found time to clean flash. Should be okay for now just to be running the rom :)

Did anyone try ANX Camera on this ROM? I care about miui camera EIS. It is much better than EIS on Gcam.

    Tip: Select OEM -> Device, choose Arrow version, choose experiments (for beta), choose build type: "GAPPS" or "VANILLA" to download.

    Recovery for OTA (custom recoveries cannot decrypt data) - included with ROM
    Arrow Recovery: Gdrive link

    FIRMWARE - included with ROM

    Install Instructions:

    Start with unlocked bootloader and grab a PC with windows, linux or macOS

    Download platform-tools and extract it

    Download ROM + recovery.img and place files in platform-tools folder, then connect your phone to PC.

    1. Open CMD, and navigate to your platform-tools folder. Then fastboot boot arrow recovery:
    fastboot boot recovery.img

    2. On device, navigate to "Apply Update" & select "Apply from ADB"

    3. On PC, sideload the ROM (copy paste the zip name)
    adb sideload "ROM-name".zip
    Wait for it to complete.

    4. On device, navigate back to home screen (top left arrow) and find "Factory Reset"
    This will factory reset the device, removing all user data

    5. Boot and enjoy - firmware and recovery are included with the ROM

    Dirty flashing:
    Just adb sideload the zip and reboot, that's all!

    Use the OTA updater in the ROM

    - if adb sideload fails, unplug and replug the device to PC and try again

    If you install magisk or other mods, do not ask for support 👌
    I discourage mods, but zips can be sideloaded like the ROM if you need custom kernels etc

    I would like to say that I tested all the Roms with Android 12 and this Arrow, is the best of them all, a wonderful rom, I found no error, the only thing I can not do, is to open an application from a specific bank, all others open normally, vives are all to be congratulated 🎊
    Same here. I installed it via adb side load. The new version is working fine.
    I'm personally using the Android 12 version on my Mi 10T 5G not the pro, but I use a gcam and an xml file to upscale everything to get my 64mp camera AND my macro working flawlessly. Took me ages to find the correct one and everything. I hope everyone who stumbled upon my post enjoys what I link below. Hopefully you can upscale yourself to 64mp, I don't have an xml file for 108mp.

    Fist APK is modified GCam and

    The xml file is to fine tune for the 64mp and Macro lense
    Yes, dirty flash (via adb sideload) right now, everything looking good.
    I tried almost every custom Apollo ROM in last months and this Arrow 12 is first, when I am almost absolutely satisfied and Mi10T Pro is right now much better phone than with default ROM or custom A11!
