I have an MC8790 that won’t register to the network or rather won’t connect to an operator on 850MHz (UTRAN). Seems to be OK on GSM. Running out of ideas about what it could be. Have reset to factory default (at&f) although that doesn’t appear to change most of the band settings etc. Have another MC8790 that seems to work fine with same SIM and hardware. Using ALIX6 board running Voyage linux distribution.
Any thoughts or ideas appreciated.
