Hello. So I've just bought a new TRB140 unit and have done a successful upgrade there, and then decided I should upgrade my old one I got last year too, which is still running TRB1_R_00.02.06.1.
The issue is that after I am shown the "Validation succeeded" page and click the "Proceed" button, the next thing I see is a a red message "Firmware update error. No image found.", and at the bottom of the page I see the following:
500 Internal Server Error
Sorry, the server encountered an unexpected error.
/usr/lib/lua/luci/controller/firmware.lua:68: attempt to index local 'f' (a nil value)
/usr/lib/lua/luci/controller/firmware.lua:68: in function 'get_magic'
/usr/lib/lua/luci/controller/firmware.lua:437: in function
I tried both the "Update from: Server" and "Update from: File" options. I even downloaded the TRB1_R_00.07.00_WEBUI.bin file which should correspond to the immediately following version to TRB1_R_00.02.06.1 according to this page: https://wiki.teltonika-networks.com/view/TRB140_Firmware_Downloads
What can I do about this?
Thanks very much.
