I have a cellular XBee (XBXC3 XBC LTE-M/NB-IoT Global) which I am trying to update to current firmware. When received, the device was on 1140B and I can update it to 1140C without issue.
However, whenever I try to update to 1140F (the transition version to 11410) it gets through the update process, waits for a reset, tells me that it has succeeded and that I should add the XBee, and then is undetected.
When recovering the XBee back to 1140B or 1140C XCTU details show the bootloader is missing.
I am using a USB breakout with mapped flow control pins.
Any ideas on how to get my XBee to 11410, or is it forever stuck at 1140C or older?
