Read the whole OP! Be respectful to each other and don't ask for ETAs, it's considered as being rude!

AOSP Extended is an AOSP based ROM which provides stock UI/UX experience with useful customizations. Being based on AOSP it provides a smooth experience. We have added useful customizations from various other open-source projects and have tried to keep our things simple. A ROM by a user, for a user. #BeExtended

I guess there is nothing wrong in reading facts!

-Why no "Incremental/Delta updates" Support?

->The updates we provide monthly are heavily changed and modified than the previous builds. New stuff is merged and added. So we don't provide incremental updates and recommend a clean flash.

-How do I root this ROM?

->We recommend Magisk

-Does this ROM Support Substratum?

->Google killed Substratum support in Pie. You can use it, however, you need to be rooted. We don't support rootless Substratum.

-Which Gapps are recommended?

->OpenGapps and BitGappps

-Will this ROM relock the bootloader?

->No.

-What about XPOSED?

->XPOSED is still in the beta stage. We like Xposed but it messes up with the system so before giving any bug reports make sure you have Xposed uninstalled.

-When Will Be the Next Update?

->No ETAs, please. ROM Will be updated whenever the new build is ready by your maintainer. We generally provide monthly updates with the latest security patches and new features.

-Adaway is not working :(

->Download it from here Adaway

-SElinux Linux mode changer app is not working nor Busy Box installer app is working.

->Everything is good with the sources. You should try other things first and then contact your maintainer.
