XBee LTE-M Failing cell modem update

+1 vote
I'm updating the cellular modem firmware on my XBee LTE-M/NB-IoT device. It is failing at the end of the update (98% point) with:

Error occured!
[Boot Failed]
- Transferring cellular modem firmware.....(retry #2)..(retry #3) ..etc..

I'm using the Digi XBIB-CU-TH development board to perform update.
I'm using X-CTU ver: 6.5.1
XBee firmware ver: 11415

I end up having to shut down X-CTU for it to stop. When the XBee comes back up after X-CTU restart it will pull the configuration data with the exception of the cellular modem information.

Try rebooting and run the update again.

I've had this problem as well.
I have the USB C connected to the front of a brand new Xbee TH,
a microUSB connected to the "USB Direct Connect" through a USB Hub.

The first time, after updating to 11415 (from 11413) the "updating radio firmware" pop up "Details" text box said
- Waiting for module to reset... [OK]
- Transferring cellular modem firmware...
It got up to "Programming cellular modem : 98 % and failed with the following

Please TURN ON the device and don't disconnect power supply

I tried a 2nd time powering off the XBEE/XB-TH board, waiting 10seconds, then powering and trying again.
Same result
