I think there is something wrong with this information about the images:
image 1) with information 09999 is LOST MODE
image 2) cell phone already restored without information is CLEAN MODE
but in the 2 images FIND DEVICES is ON
Either Lost or Clean still cannot be flashed because "Find device" is turned ON.
so if you can flash your K20 Pro it is because simply "Find device" is turned OFF.
and here is the proof of what I say ...
Xiaomi MI 9T is Clean does not flash :
View attachment 16720
the same here, I just flash because "Find device" is turned OFF ....
