Greetings to all.
Enable support for 4G networks from GSM-operators in the first slot for the SM-N9109W to Android 5.0.1
In ServiceMode came here
MainMenu ->[2] UE settings & INFO ->[1] Settings ->[1] Protocol ->[2] NAS ->[1] Network control It is interesting to the two settings, and they are interrelated.
[4] Band selection and
[5] Pref mode set "Band selection" is applied on the fly, it is not necessary to restart. In fact, this is a mode switch of the first slot. I'm standing in the Automatic and slot accepts RUIM and SIM, Sim works in 2G-3G-4G depending on network coverage.
"Pref mode set" should be set to CDMA_LTE_ONLY. Then the phone will automatically switch between the GSM-CDMA.
Of course before this took SIMlock
same
MainMenu ->[2] UE settings & INFO ->[1] Settings ->[1] Protocol ->CDMA ->TEST_SYS->CTC OPERATOR NAME to Disable
Still, just in case it is applied
MainMenu ->[2] UE settings & INFO ->[1] Settings ->[1] Protocol ->[1] AS ->[1] Frequecy lock ->[7] RESET - it clears all the locks on frequencies.
