    • Almost everything

    • You tell us
    Be sure to include a log : check how to


    Q1: Is this device specific build or Generic System Image ( GSI ) ?
    A1: This is device specific build, not GSI

    Q2: Is this rom rooted by default?
    A2: No.

    Q3: How to root?
    A3: by flashing Magisk from TWRP

    Q4: How to update manually when a new build is available?
    A4: Download, reboot to TWRP, flash the new build + you can also wipe Dalvik and cache!

    Q5: Is GoogleCameraMod working on this rom?
    A5: Yes
    Tested GCAM:

    Sometimes front cam may not take a pic in Google Camera Mod. A trick is you switch to the rear camera, take one pic and switch back to front cam, it will be working. REMEMBER: This is on P blobs and you will need the latest Pie firmware!

    UPDATE: Any GCAM which works fine in stock pie should work fine here as well!

    Q6:playStore notifications are not working!
    A6: Common issue in Pie thanks to Google
    Go to :
    * Settings -> Apps & Notifications -> "See all apps" -> "Show System". Search for "Data Transfer Tool" or "Android Setup"
    * Disable them both and reboot your device..
    * Play store download notification will start working from now! (reboot if needed)

    Announcement: We have released device sources of X01BD which we brought up in collaboration (bauuuuu and me i.e kubersharma) for custom development, so anyone can compile any rom with these device sources and for collaboration (fork and make a pull request for contribution, we shall review it and then merge if needed and only if it is legit)
