Hi thank you for all the good work flashed Arrow-v12.0-starlte-OFFICIAL-20211227-GAPPS yesterday evening : -) very smooth and clean, no bloatware, though Updater says bad gateway could not connect to server try again later, will try later or to update manually, everything works what a pleasure.

Inicie en la recuperación TWRP, vaya a Borrar, seleccione Formatear datos, le pedirá que escriba sí, cuando termine, vuelva a Reiniciar y seleccione Recuperación, después de reiniciar en TWRP, vaya a Borrar y Borrado avanzado y seleccione Sistema, Caché, Datos y luego Deslizar para Limpiar, vaya a Instalar seleccione el Zip y flashee, después de flashear limpie Dalvik y reinicie.

Translated by GT: Boot into TWRP recovery, go to Wipe, select Format data, it will ask you to type yes, when done go back to Reboot and select Recovery, after booting into TWRP go to Wipe and Advanced Wipe and select System, Cache, Data and then Slide to Clean, go to Install select the Zip and flash, after flashing clean Dalvik and reboot.

Great Rom! installed it a few hours ago coming from Los 18.1 and so far so good. I went for the vanilla build with basic FlameGApps. No issues so far but will update if that ever changes. Keep up the awesome work devs :D

Thanks for the nice work but i found a small bug..

When I switch to file transfer during a usb connection, the device restarts.

In developer settings I switched to file transfer and it was resolved.

Peace !

( sorry for my language skills )

Make sure to disable usb debugging in developer settings .
Also it was reported that using vanilla + full nikkgapps had it working.

I don't have android auto car so I can't try it myself

Everything seems to work okay so far on this rom, I came from Alexander's dev build haven't noticed no issues or bugs.

So thank you dev.

One issue tho, not exactly a issue but how to I disable the on screen screen saver clock when I don't use my device? I don't want to see the clock when my device isn't being used.

    Regarding updates I think many notice that OTA was stopped and the download links showing as discontinued. That because android 12.0 support has been ended in favor of 12.1 which will be available soon.
    The problem with 12.1 is google released a broken sources AGAIN and the current state of 12.1 is not good for public release. I would estimate another month for a stable release.

    What about encryption:​


    Flashable zip to enable encryption is in this post
    How to enable encryption

    I posted this in Telegram Channel :​

    "One important thing is the encryption thing and I know the majority voted for it to be included but I'm truly sorry to go against the majority as encryption will make my development work much slower and there will be always a risk to lose data from my side which I can't afford. So no force encryption in arrow-12.1 and it won't work unless it was forced at boot(changed in fstab).​

    However I'm planning to provide a flashable file that will enable encryption but it need further testing to make sure everything is working correctly.​

    I hope everyone understand my decision and sorry again if you don't agree with it."​
