It is working!!!
Can you please elaborate? I really want to send my ST to you but you're not sharing any information. Can you really recover a bricked tablet from APX state after the kill switch is activated?
I have send my motherboard to drims75 from Austria.
It was already stuck in APX mode no change to reactivate.
Today I received my motherboard back and rebuild it to my tablet.
It is working now with android 7 serial number changed (fully official nvidia update no problem) also the battery type is showing now B01.
All I can say now drims75 has really done the job and it is working now.
Always when I ask a question to drims 75 I get very fast answer with pictures.
So please trust him he can repair.
I made photos from my repair process if you need any information please ask!!
I am so happy!
Best regards from Austria to Drims75 and all of you!!!
