Just tried the root procedure for Onplus 6T but not work

[Paul-LKW]

###>adb shell sh /storage/emulated/0/Android/data/com.mordred.agelaroot/files/angelaroot_starter_step1.sh
info: angelaroot_starter.sh STEP1 begin
Starting: Intent { cmp=com.android.engineeringmode/.qualcomm.DiagEnabled (has etras) }
Error type 3
Error: Activity class {com.android.engineeringmode/com.android.engineeringmode.ualcomm.DiagEnabled} does not exist.
Ok, STEP1 is completed, let's do STEP2

I got the error above any way to fix it ?
Many thanks for your effort to make tools to root ^_^

com.android.engineeringmode.qualcomm
is already removed from the firmware Oneplus offered. Thus this method will not work.

Just unlock the bootloader and flash magisk in and everything will be fine, except your data will be wiped during the unlock procedure, as a security precaution someone picked up your phone and unlocked it s bl to peek inside.
