RE: Dell Inspiron 15 3542 bios firmware update problem windows 10
I have done the Downgrade procedure but it didn't work because the default firmware was A1 for 3542 and it updated to A2 for 3442( It worked from A3 to A2 for 3442( 3442a02 drivers). So when i try to downgrade from 3442 to 3542 it says that is is a different system. The same goes if I try to update from 3442 to 3542 for A3( 3443a03 drivers). I don't understand why it let me update the firmware in the first place when the drivers are for different system.
