I have 3 sets of the RRC1258MkII.
The first two sets FW upgraded with no problem using USB.
The third set will not upgrade FW using USB. I get the Error 31 message.
After failing trying USB, I was able to upgrade the 3rd unit's FW using the web, I think, But usb still is dosen't work.
The revision of boot loader on the failed unit says N/A and FW is now version is 000.000.002.050 unlike the other two sets that report firmware is 2.50. and boot loader is 1.9. HW is ver 6 on all sets. Have not tried to config this unit for radios yet, but the other two are working well.
How do I fix the missing bootloader and FW revision number?
