Are you guys sure that random freeze problem, is created by wrong bootloader unlock method. Or Fault in ifwi files.??
If this is true, please intimate me then I should start to look in those files as Every rom is close to stability except freezes.

Use this boot-stock.img


goto fastboot mode

fastboot flash boot boot-stock.img

fastboot erase cache

wait until finish

- Double tap to wake up don't work
- Battery work better with normal usage (+- 7-8 hours)
- Screen very smooth, no lag any more

Thanks in advance for reply.

well.. it's a hard decision.. for anyone looking custom rom can try RR roms, for the others.. can stay on kitkat, lollipop is still not better in sim management, but others than that it still have bugs, but for me it's not so annoying except for the sim management (i cant text with the 1st sim when i call with the 2nd sim, that's bad news 4 me)

    SInce the fix for @knoneNull's build is scattered over the thread, and to break the hassle of "buggy", "too much lag", "freezing", "error 504 in playstore blahh blahhh blahh I'll revert to my previous rom", the thread should be updated. In behalf of knonenull, tank0412, omercicek43 and the other member who participate in this thread, I kinda make a brief guide. Nonetheless,

    I will not be discussing the adb, fastboot, unlocking bootloader and the likes

    Flashing the base:
    1. Go to the bootloader.
    2. Flash the base
    fastboot flash boot-newDTW.img
    fastboot erase userdata
    fastboot erase cache
    fastboot flash system system-DTW.img
    3. Now reboot and you should have the CyanogenMod built by knonenull

    For the fix:
    I assume you had flashed the rom.
    A. For the annoying storage notification problem and google sync problem and the error 504 you encounter while downloading at play store replace the build.prop in your rom from this post

    I made my own flashable zip file containing the build.prop given by knonenull

    B. For the graphic issue, flash this in bootloader, this should be flash as boot image.

    C. For the photo save in external sdcard bug, update it here. Posted by @knoneNull here

    Summarizing the procedure.
    Latest procedure
    fastboot flash boot boot-6.img
    fastboot erase userdata
    fastboot erase cache
    fastboot flash system system-DTW.img

    Previous procedure
    fastboot flash boot Module-graphics.img
    fastboot erase userdata
    fastboot erase cache
    fastboot flash system system-DTW.img
    then flash the attach file in the TWRP made by knonenull again, be sure to mount the system to work.
    To boot-6.img
    fix camera to save on external sdcard
    revert back temporary the healthd for off line charging icon

    Note: There is an autoinstaller made by tank0412 but for those who are fond of manual flashing give it a shot.
    Also if this post is redundancy, and if @knoneNull and the other find it improper, I gonna delete this post.

    My purpose is to guide those who are about to flash @knoneNull's build because I find the thread confusing. As myself was confuse couple of hours ago and read every pages of the thread in order to fix my problem, and to make an ease.
