Hi
I have been delivered new TRB141 devices with Firmware Version TRB41411_R_00.0104.3 and require the lastest firmware editions 2.05.* but when I try and upload the bin file it suggests the file is in an "incorrect format". If I try server based upgrade it works, but I do have to upgrade the firmware 3 times to arrive at the lastest release. I dont wish to use the server upgrade file path because the SIM card is on a metered network.
If it is required to upgrade progressively - how do you do this with the *.bin files. The website only seems to have 2.03.* as the oldest.
Any advise on how to efficiently upgrade the firmware would be appreciated.
Ian
