I'm coming from ArrowOS. I flashed the firmware as asked but it's still showing script error Update Error... This script requires modem version 12..., Flashed multiple times and factory reset but nothing working. Any help would be much appreciated.

Is there anyway you could add omniswitch from omni rom. It's alot better than generic android recents app. Has way more options too

i've installed the latest build (13-mar) - flashed 'clean' exactly as instructed. android security update is dt. 05-feb. battery seems to be draining fast for me. contacts keep getting flushed frequently and have to be imported accordingly. facing issues in post-rooting situation - see screenshots. anyone able to fare better?

another thing - maybe not rom-related: true phone app can be installed, but after flashing the 'root stub' module, the app disappears. i wanna get call recording in true phone app. can anybody help?

annoyance: i have the latest build (cross-checked md5), yet i get constantly notified that a system update is available. can this be removed?

p.s.: is crDroid of 12-mar better than this rom? does anyone think/know the above issues are not presented in that rom?

@Carlos Arriaga, very nice ROM, but it has 2 anoying thing from my point of view.
  1. I didn't find, how to associate another functions to the back/home/last keys for long and double touch. I use it very often and I miss it here.
  2. It would be great, if there is choise of the fingerprint functionality - immediate response / response, when you touch the key.
Is there any chance? Txt.

Coming from RR A10. Before I install this rom, should I flash latest MIUI to get current firmware, or will this get updated by flashing the AEX rom.

Edit: just red in the OP to install first Global 12.5 Firmware.

I just red that Poco x3 get MIUI 13 update in India. I have the global version and most likely it'll get the update too later. With that I guess new firmware will be released. How do this affect this AEX rom since current official firmware is based on A11 ? Will there be an update as well for the jew firmware or will we be able to update the firmware manually?

    I guess there is nothing wrong in reading facts!

    -Why no "Incremental/Delta updates" Support?
    ->The updates we provide monthly are heavily changed and modified than the previous builds. New stuff is merged and added. So we don't provide incremental updates and recommend a clean flash.

    -How do I root this ROM?
    ->We recommend Magisk

    -Which Gapps are recommended?
    ->OpenGApps and NikGApps

    -Will this ROM relock the bootloader?

    -When Will Be the Next Update?
    ->No ETAs, please. ROM Will be updated whenever the new build is ready by your maintainer. We generally provide monthly updates with the latest security patches and new features.

    -Adaway is not working :(
    ->Download it from here Adaway

    -SElinux Linux mode changer app is not working nor Busy Box installer app is working.
    ->Everything is good with the sources. You should try other things first and then contact your maintainer.
