adbを使用したGWL/LTE ONLY/WCDMA ONLY/GSMのpreferred_network_mode値

Question

以下のadbコマンドを使用して優先ネットワークモードをGSMに変更します。値が1の場合は、 - GWL/WCDMA/LTEONLY） - LTE ONLY - WCDMA好適など

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 

Answer 1

私はそのうちのいくつか

LTE ONLYのための答えを得た - 11 WCDMA - 2 GSM - 1
