...

you must have formatted in SP flash tool before flashing the firmware, there are other hidden partitions that shouldn't be tampered with unless you made a backup
did you by any chance make a full emmc_user dump from your phone before flashing?
can you get access to another CCIT Xedition phone that doesn't have this unwritten tee problem? -- this might not work but its worth the try

Your Serial Number looks off; 0123456789ABCDEF . Check if your phone has valid IMEI. Maybe SN Writer @ https://www.hovatek.com/forum/thread-12306.html can help

Option is to deinstall the Factory Mode App using ADB/SDK Tools with PC but Without ROOT
All you need to do is Download this: www.mediafire.com/file/cc443705xa3e6mg/minimal_adb_fastboot_v1.3.1_setup_2.rar 
U must enable USB-Debugging on your Ulefone Power 3/3s. (no matter which Android version)
Connect your Smartphone with your PC using USB Cable.
Then start the Program you downloaded before.
Maybe you Have to Confirm the Debugging on your Smartphone.

1. Type into the Console:

Code:

adb shell "pm list packages | grep com.mediatek"

If the app is preinstalled on your device then it'll show up in the output, if not then output will be blank


2. Type into Console to temp uninstall the app:

Code:

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

You should get a "Success" message
Restart your phone and confirm that the Red 未写入key or 未写入tee key is gone. Note that if you factory reset the phone then you'll have to repeat the procedures all over again


I hope it Works and sorry 4 my bad English.

as it turns out, that test will no longer be necessary. it probably won't work
if the method @ https://www.hovatek.com/forum/thread-287...#pid188826 doesn't work for you then contact your OEM, they should send you the tools / files needed to write back the original tee / google key for your device
