I'm on latest MIUI Global firmware: 12.5.1
Above it is written that it's required MIUI 12.5.0.4
Is it ok to flash this ROM on latest MIUI Global 12.5.1? Nowadays it's not so easy and safe to rollback to a previous Global version, so if possible I would flash directly on 12.5.1...

Thank you very much I will try it ... It seems that it takes a long time in the first boot

Edito: Well, it does not go beyond the start animation, it takes too long, I have passed the dfe and it remains the same ... Any ideas?

I have done all the wipes including format data

    Hello to all
    First thing thanks to all for nice/awesome words :)
    Here's about bugs you faced guys
    * Face Unlock not exist on all A12 ROMs, not just ArrowOS or Cepheus
    * Fingerprint doesn´t work: I switched to new FOD hal, so maybe it's not compatible enough
    * signature spoofing: it's working now, check last release on arrow website
    * dialer/caller: has been fixed, this problem is exist only on that build (11/24)
    * ANX camera: not working on all ROMs and all devices, not just Mi 9 So wait until ANX devs fix it
    * Black Theme & quick unlock or other features, look Android 12 is still beta and ArrowOS team still adapting it and all things that was on arrow 11 will come to 12 but it's need time
    * For Screen OC/75hz try to use custom kernels like Kneip..etc
    * yeah NFC not working, it's known bug, if you use it as daily usage try to back to first release

    Last but not least, don't expect custom ROMs to work perfectly, I do my best and if there's anything wrong don't blame me
    Also use only community dont use community experiment it's bugy or not even booting

    Thanks again and see you in another update.

    I'm confused about the title. The title said its a official stable version. When i click on download then it shows me the unofficial version. On the website when i click on Arrow-12.0 then it shows only the community experiments. So the title is a missdirection.

    How often/long do you have plan to do updates/security updates?

    Thank you for answer and for your time.
    I updating the ROM every month since April!!
