Stuck on 20160829 (10637)

[srbrenton]

Tried this evening to go forward to the beta.
Best results with iMac USB2 with Connectivity Kit Build: 2017 11 15. Rev:13011
Manually put 20171115 in Connectivity Firmware folder.
(Also tried Bootcamp Windows 7 Pro and Windows 10 on new Lenovo laptop.)
Connectivity Kit and calculator go through the motions, progress bar, etc.
Still on 20160829 when finished.
After loading 20160829 earlier this year was not able to reload calculator backup.
(Clearing Memory Flashed on calc display)
Tim asked for a copy of the backup file and I sent it to him. (Haven't heard back.)
Able to put calc in recovery mode with FCO and reset button.
Software Version: 2016 08 29 (10637)
Hardware Version A
CAS Version: 1.1.2-11
Serial Numer:4CY3500CVD
Operating System: V0.037.526

I'd appreciate any ideas, thanks!
