If could be

If you have a previous backup of the following 3 partitions (proinfo, protect1 and protect2) then simply flash them back to remove the red text but if you don't have a backup of these partition then continue with the guide below

  2. Scroll down till you find the file named "build.prop", Long press the file > Edit the file
  3. Search for the properties below
    Code:

    ro.mtk_trustkernel_tee_support=1
    ro.tee_support=1

  4. Modify the values from 1 to 0
    Code:

    ro.mtk_trustkernel_tee_support=0

Method 2: ADB shell

Steps

Run the following commands

Code:

adb shell
pm uninstall --user 0 com.android.watermark

If the last command doesn't work try

Code:

adb shell pm uninstall -k --user 0 com.mediatek.factorymode

Method 3: SN Writer with TEE support



  1. Download a version of SN Writer with TEE Support (e.g v1.2020.0.0-415) @ https://www.hovatek.com/forum/thread-15450.html
  2. Write the original IMEI(s) using SN Writer

Important Notice
  • If you don't find the search properties within build.prop in /system partition, search for them within the build.prop in /vendor partition
  • This might also work for those who encounter the error "Not efused" or some chinese text displayed at the top of their screen in red color. You can try and let us know the outcome
