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.

After flashing rom, it gets rebooted into download mode. Cant fix! Any help?
1-Wipe vendor , system , data , cache
2-flash vendor (your stock oneui 2.5 vendor) as vendor image (only if you were on noble ROM (one UI 3.1)
3-Rom , gapps (for Vanilla version) and magisk (if needed)
4- Reboot and Ur good to go .

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.

    Encryption is debatable as for it to work I need to force encrypt at first boot which mean no TWRP support. I still did not decide which way to go but I will soon
    Please, please, please, don't force encrypt 🙏

    Android 11 QPR3 or higher supports the cached apps freezer,But it seems that it supported by Linux kernel.How I can get this feature on my arrow 12 samsung s9?
    Should i flash a newer kernel?
    Need at least 4.14 kernel, we have 4.9.
    Did it simply dared times, dirty to flash the pre-release version 12.1 on my existing 12.0.
    Was lazy to flash everything clean.
    This has so far also works.
    All apps have been adopted and work.
    Security update 4/2022.
    Only Magisk was broken and I had to flash new.
    As far as once happy.
    And I am convinced that Arrow will get better with time.
    Thanks to the developers for the effort and time.
    You are welcome
    Great 12.1 pre-release build.
    Looking forward encryption and if possible liveDisplay (on latest 12.1 build, screen colors are very staturated).
    Thanks for all the work to the developers, you rock guys.
    Livedisplay wont happen anytime soon. Encryption is debatable as for it to work I need to force encrypt at first boot which mean no TWRP support. I still did not decide which way to go but I will soon
    Is it correct that face unlock not working in 12.1?
    I have looking everywhere but I can't find information about it.
    Arrow does not support this

    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.
