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

#ExtendYourDevice Here are the Extensions! on top of AOSP! We are constantly trying to update the list. Our aim is not to provide all the features available on earth. Our aim is to add important features that we think should be here and also what you think. For addition of more tweaks or features, head on to our G+ community and post the list of features that you want! Features with commits will be more helpful!

I guess there is nothing wrong in reading facts!

-Base Of the ROM & Version?

->Rom is based on AOSP.

-Why no "Incremental/Delta updates" Support?

->Actually 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.

-Does this ROM Support Substratum?

->Yes, full Substratum support!

-Which Gapps are recommended?

->OpenGapps

-How do I root this ROM?

->We recommend Magisk

-Will this ROM relock the bootloader?

->No.

-What about XPOSED?

->XPOSED is still in 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 latest security patches and new features.

-I am facing FCs, Bugs, Some feature is broken?

->Provide full info about your problem with logcat and the procedure to reproduce it.

->How to take Logcats?

->https://goo.gl/UcTM9 and https://goo.gl/J4CSEP

-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.
