i remove my mini 9 dell 5530 wwan card , to replace the Sierra MC8781 and Option 378 wwan card , none of them is working.
Option 378 - did not dectect by mini 9 , cant see any new device in the device manger , mean undetected.
MC8781 - cant boot up bios at all , mean swich on about 10 second , mini 9 will auto shut down.
Dell 5530 - is working fine , i even tested in my samsung q1u is working perfect.
i suspect as below :
1. bios lock ? but i have tested all bios from A01 to A05 , result is still fail on mc8781 and option 378
any trick or way to enable my mc8781 and option 378 wwan card into mini 9 and use it
any one , can help me and give me some guide , thank in advance
