I am using below adb commands for changing preferred network mode to GSM where value is 1, Can any one give the values for other modes like - GWL (GSM/WCDMA/LTEONLY) - LTE ONLY - WCDMA PREFERRED etc
adb root
adb wait-for-devices
adb shell sqlite3 /data/data/com.android.providers.settings/databases/settings.db "update global SET value=12 WHERE name='preferred_network_mode'"
adb shell sqlite3 /data/data/com.android.providers.settings/databases/settings.db "select value FROM secure WHERE name='preferred_network_mode'"
adb reboot
typedef enum {
PREF_NET_TYPE_GSM_WCDMA = 0, /* GSM/WCDMA (WCDMA preferred) */
PREF_NET_TYPE_GSM_ONLY = 1, /* GSM only */
PREF_NET_TYPE_WCDMA = 2, /* WCDMA */
PREF_NET_TYPE_GSM_WCDMA_AUTO = 3, /* GSM/WCDMA (auto mode, according to PRL) */
PREF_NET_TYPE_CDMA_EVDO_AUTO = 4, /* CDMA and EvDo (auto mode, according to PRL) */
PREF_NET_TYPE_CDMA_ONLY = 5, /* CDMA only */
PREF_NET_TYPE_EVDO_ONLY = 6, /* EvDo only */
PREF_NET_TYPE_GSM_WCDMA_CDMA_EVDO_AUTO = 7, /* GSM/WCDMA, CDMA, and EvDo (auto mode, according to PRL) */

PREF_NET_TYPE_LTE_GSM_WCDMA = 9, /* LTE, GSM/WCDMA */
PREF_NET_TYPE_LTE_CMDA_EVDO_GSM_WCDMA = 10, /* LTE, CDMA, EvDo, GSM/WCDMA */
PREF_NET_TYPE_LTE_ONLY = 11, /* LTE only */
PREF_NET_TYPE_LTE_WCDMA = 12, /* LTE/WCDMA */
PREF_NET_TYPE_TD_SCDMA_ONLY = 13, /* TD-SCDMA only */
PREF_NET_TYPE_TD_SCDMA_WCDMA = 14, /* TD-SCDMA and WCDMA */

} RIL_PreferredNetworkType;
