Hello,
I yesterday try to update to TRB500_R_00.07.08.2 which wasn’t possible trough FOTA as the modem would say downloading and then nothing. So I downloaded the BIN file a used the file approach. I got into upgrading, but the modem never started again.
Can I ask how can I troubleshoot it? I didn’t find that TRB would have bootloader mode same as RUT does, or is it there?
Right now the modem blinks with all signal leds few times, then other status leds blinks with it once and then dark for few seconds and all this again.
Thank you very much for help
