Donations help cover the build server cost and since I do this in my free time, and also cover the coffee for time spent debugging stuff

Feel free to join telegram group with early builds progress updates and some off topic stuff Join

Due to requests from some users I added signature spoofing support to the rom which allows usage of MicroG

you can simply install MinMicroG and grant it needed permissions for signature spoofing to make it work as intended

Based On Android 11/R
