Here is a fun fact...
Went to update my 4000NEX last night. Have had zero problems updating to previous versions in the past. Plug in the USB drive and start the process and notice on the screen that is upgrading from 1.09 > 1.08.
Surely this must be a mistake that got through QA I thought to myself. Plus, I am past the point of no return anyway so I let it complete. Sure enough it downgraded me from 1.09 to 1.08.
OK, perhaps I downloaded the wrong file (I know I didn't but you never know) so back into the house I go and re-download the 1.11 firmware for the 4000NEX. I download the right file again and erase my USB drive and put the 1.11 back on it.
Back to the garage I start the process again. Sure enough, the update process says it is going to update it from 1.08 > 1.08.
WTF?!?
Turns out I still had an SD with 1.08 on it in my unit and instead of reading the data off of the USB drive, it took the update from the SD card instead - even though it was older and it downgraded my headhunt which I didn't think you could do.
In any event, removing the SD card allowed me to update to 1.11 but the Bluetooth update didn't bump my Bluetooth version (I don't think) as it still reads 3.21.30 but I'll try that portion again later and see what happens.
