The screenshots are blank for me (flashed this one days ago)

Edit: Oh wait, does strikethrough actually mean it's fixed in a to-be-released version? Thought it meant it'd been fixed recently.

Patch in the new custom kernel (Magisk)!

Thanks for this! It's amazing.

Bugs I've encountered:

  • Phone rarely freezes on a black screen, and the only function accessible is the power menu (hold down power button), where you can shutdown/restart normally;
  • Wallpapers reset to default in some reboots;
  • Am not able to change home/lock screen wallpaper individually anymore;
  • Screenshots are blank using the ROM's native one and/or with any screenshot software;
  • In some applications that output audio (at a full-time instance) even with the whole phone volume at 0, it will output audio for a brief and short momment (but at the highest volume);
  • MagiskHide isn't working / SafetyNet can't be passed. There's a kernel update that got released some days ago which fixes this for older Android devices running custom roms https://www.xda-developers.com/magiskhide-older-android-devices-custom-kernel-patch/ ! ;
  • (edited 07/23) - Hotspot function DOES NOT WORK with data turned on. It displays as an "ERROR" below the hotspot config switch, and the connected devices bug out. They are still "connected" to the i9082, but with no data transfer. Also Wi-Fi direct can find and connect to other devices (buggy!) but can't transfer files, as no prompt will be given out to the receiver or sent by the other host phone.

Really hope for an update on this soon!
Again, thanks for this! It's amazing to have 7.1.2 on my Gran Duos.

Not working(WIP)
RIL (Having a tough time with this one)
WIFI (kernel commits needed)

Once i can fix ril, the rest shouldn't be too difficult for me to fix. Ril is the hardest part

BTW a new lineage 14.1 build might be up this week. Testing some changes....

Any news on the Oreo ROM for our device?

    LineageOS is a free, community built, aftermarket firmware distribution of Android 7.1 (Nougat), which is designed to increase performance and reliability over stock Android for your device..
    Your warranty is now void.
     * I am not responsible for bricked devices, dead SD cards,
     * thermonuclear war, or you getting fired because the alarm app failed. Please
     * do some research if you have any concerns about features included in this ROM
     * before flashing it! YOU are choosing to make these modifications, and if
     * you point the finger at me for messing up your device, I will laugh at you.
    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
    All the source code for LineageOS is available in the LineageOS Github RepoAnd if you would like to contribute to LineageOS, please visit out Gerrit Code Review

    Device-specific source code:
    Device tree
    Kernel source
     Compatibilitiy Patches:


    What works?
    RIL (Calls, SMS, Mobile Data)
    Sensors (Accelerometer, Compass, Light, Proximity, etc.)
    Video (playback & recording)
    Audio (playback & recording)
    Everything else not listed under "known issues"

    Known Issues
    Screenshots and Recents App thumbnails are blank
    Runtime storage permission does not fully work (setns kernel patches are not applied, see com.android.cts.appsecurity.PermissionsHostTest#te stInteractiveGrant CTS test. After granting permission, the app will need to be restarted before it sees the new permission.)

    Additionally, Dual SIM has the following limitations (once they work):
    Both SIMs are always enabled (no way to disable one SIM)
    "Receive incoming call while data is enabled" is always enabled

    Make a backup!
    If you were on CM 10.1 or a stock ROM prior to 4.2, upgrade to stock 4.2 first.
    Install ClockworkMod recovery with SELinux support. Older CWM will result in a "status 7" error.
    Reboot into recovery
    If you are using a recovery which mounts /system on boot, unmount it before installing
    Wipe data if coming from stock or other ROMs (You may get a "status 7" error if you fail to wipe.)
    Install the ROM
    Optionally install the Google Apps Addon (In Marshmallow, you MUST flash gapps before booting into the system for the first time or else the proper permissions will not be granted resulting in Setup Wizard crash. If you experience the crash, you will need to do a factory reset.)

    To upgrade to a newer build, simply flash the zip. There's no need for data wipe or flashing Google Apps again. (However, if you are experiencing strange issues, you may want to try a wipe.)
