Hey Joe, I tried to uninstall the drivers several times with installing 1309 and 1311 interchangeably to see if one of them would do the trick.
I have tried to re-fit the SSD as Maibad31 suggested helped him as well as trying to re-fit the Wireless AC 7260, but it does not fix my issue. I have also tried connecting only the main antenna which of course had no effect on the BT.
Bluetooth still show code 43 with the 1309 driver or Unknown device descriptor with the 1311 driver.
Can you please advise on this issue.
Omer
