Excelent work @kevios12 . Thanks for that.

I flashed it clean initially, but it did not work well. So I had to reflash the latest stock ROM (from here), flash it with odin, the install TWRP 3.6_kevios, and only then install this image + BitGapps.
Working smoothly so far, really happy with it.

So far, the only functionality that does not seem to work is the "Automatic brightness" thing, but the rest seems even better than the previous crdroid release.

I flashed the ROM too. In the setup wizard it wasn't possible to set up the Google account and i couldn't find the option to restore my cloud backup in my Google Account, when i set it up later, but the ROM works really well!
Is it possible to set the theme to pure black?

Hi, the ROM is actually a Beta. It can contains bugs.

Thanks for this great FW! It makes this A40 device really smooth again. Only experienced some WiFi dropouts with a connected FRITZ!Box 7590AX (WiFi ax, 2,4 and 5 GHz with WPA2/WPA3). And how can the Google Camera app be used (as the most easy camera interface I know)? Crashes after starting the app here.

Also the problem with BitGapps is that it does not resinstall itself after installing an update. Nikkgapps does that, but I'm not sure it's compatible. Anybody?
 
Flashed the ROM yesterday. Great work, thanks a lot :)!

Unfortunately I went into bootloop at cr Droid logo after doing this: enabling adb debuging (USB and root), then additionally choosing "data transfer" (in German: Datenübertragung, I don't know, what's the correct term in English) in USB. The phone shut down after about 2 Mins I did this. After that no boot possible.
I have a logcat (2.8 MB .txt file). I tried to attach it. Unfortunately that doesn't work. I think it is because of the 10 posts rule. But I could send the logcat in another way, if anybody is interested (in this case please tell me how eg. mail...).

Thank you for this great work. After 10 days of trial , the ROM is adopted :) and I have updated to 8.2.

My main concern is sound volume which is too low. With a boost volume application (Volume Booster by Goodev) I can get good sound volume. My ROM is rooted and I wonder if it is possible to adjust sound volume permanently with some configuration and avoid to use a volume booster app.

Hello All,

I have already cdroid 7 on my wifes phone,but I see a little lag with UI (not ROM related)
Do this ROM has the same glitch/lag as above.
Is it a daily driver ROM,so no reboots or any other .

Kindly regards
