    Now install dtb as already described. Then install aml_upgrade_package.img.

  • Method 1 Steps to install stock android 7.1.2 image

    No. Repeated unnecessarily.

    1. Write aml_upgrade_package.img on the mSD card with Amlogic Burn Card Maker.

    2. Copy _aml_dtb.PARTITION to the FAT partition of the mSD card and rename the * .ini file to * .ini.bak.

    3. Start the TV Box from this mSD card and write the * .dtb.PARTITION on eMMC.

    4. Remove the mSD card and rename the * .ini.bak to * .ini again.

    5. Now start sd card upgrade.


    P.S. In your case, the vendor uses the misc partition, which contains certain key signatures for certain applications. A manual installation of individual partitions does not help you, as the misc partition also has to be installed. Otherwise the stock fw will not run.

    error system UI has stopped is flashing on screen again and again....


    edit

    In my observation, system UI stopped error comes when,

    "system first time initialization of app" not come on android first boot..

  • s4shail

    Code
    avc: denied { write } for pid=4700 comm="ndroid.systemui" name="property_service" dev="tmpfs" ino=8243 scontext=u:r:platform_app:s0:c512,c768 tcontext=u:object_r:property_socket:s0 tclass=sock_file permissive=0

    Sys UI

    Try to create a new rule for property_socket in sepolicy, allow write access to the sock_file:

    Code
    (allow platform_app property_socket (sock_file (open write)))

    and recompile sepolicy..
