Recently, I flashed the builds of 20220102 on my LG G8 Korean version, it works great, cause I used it as my second phone, very satisfied so far. There is just a small bug, that is, the first row of icons in the apps library cannot be fully displayed. Is it possible to add a screen display in the next builds ?
Anyway, thanks a lot for your works !

I found another bug on alphalm latest version, when there is an incoming call, my phone keep vibrating about 15 seconds (no button to answer the call) before the popup Answer/Reject appears.

Could you please instruct me how to go back to earlier build or how to boot to TWRP ?
New build is uploaded for the fix. Would you please help me to flash it.

To back to TWRP, just go to Arrow recovery, select Advanced, choose switch slot and select other slot. Then reboot to recovery.

The Wifi is now working again. Thank you.
Edited: Bluetooth is working but with my tws earbuds I cannot hear anything from media. When I switch the audio sources, it will play sound on phone speaker although I choose my earbuds.
Edited 2: Double Tap to wake up not work

New builds are uploaded to fix dt2w. Please test the rom with Youtube to see if the FPS drops to 30 or not. Also test with some games since the kernel now undervolts gpu.

Youtube is now running normally and the earpiece audio is working fine. I tried to install magisk from the arrow recovery when updating but it didn't installed it and for some reason i can't get to the recovery from the button combination nor the advanced reboot menu. Everything else is working fine for me.

Thanks for your work.

    I have the bootloader unlocked and not rooted. I wanted to install the custom rom, but I don't have Twrp on my smartphone, does anyone have a step by step on how to install TWRP

    I used to use TWRP to install roms but i gave in and started using Arrow Recovery. Used to use Magisk to install TWRP. There are instructions on how to install it on the bootloader unlock guide.

    Hi all - first, about the download link, it is AndroidFileHost issue and I have no way to make it work. I just create MegaDrive account for new upcoming builds. The alphaplus test build is already uploaded into it.
    Second, perhaps my kernel is causing the issues. This weekend I will try to use kernel source from Markus (v50 dev) to see if these issues still happen or not.

    If you guys still want to use my ROM, please be patient. I still have my own life and this rom was created for my personal use initially. Because there are no devs for G8, I decided to share it here and didn't expect any donation. I'm really new to Android rom development and ArrowOS is my very first rom which I have ever built.

    Happy new year all! New builds are uploaded into Megadrive: https://mega.nz/folder/iQFXCSAa#N_SqYZA1TptEJVyPVg5iXw

    Michael Smirnov helps me to test alphaplus build and he says its battery is better now.

    Two new builds are uploaded. Don't expect battery draing is fixed. I'm still need to investigate it.

    I found the developer in the telegram channel https://t.me/v50thinq and asked him to update the latest firmware version. Here is the link, lets download, install and test))) https://mega.nz/folder/XEEVDCIR#QtlnMaX2mq9juB8GGyoUHw

    Bluetooth music now works for me, DAC works too. The battery drain i began to be tested.
    The speaker with phoinecall is not working properly. The interlocutor hears himself during a telephone conversation. Ie noise reduction does not work. Check out how you are with that.

    Otherwise, everything is perfect!
