This is working for my devices:

adb shell sqlite3 /data/data/com.android.providers.settings/databases/settings.db "update global SET value = 1 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 shell settings put global airplane_mode_on 1
adb shell am broadcast -a android.intent.action.AIRPLANE_MODE --ez state true
sleep 5;
adb shell settings put global airplane_mode_on 0
adb shell am broadcast -a android.intent.action.AIRPLANE_MODE --ez state false

Could you mention why `sleep 5` is needed? And which Android version are your using? – Jul 01 '15 at 10:29
Beside is there a reason `sqlite3 ...` is used and not `settings put global preferred_network_mode 1`? Also, what does second command does? – Jul 01 '15 at 10:32
Nope! Not working on CM12 rooted. It changes the value in `.db` but the changes doesn't take place on the radio level. You can check it in "Phone Info" through `*#*#4636#*#*` where the preferred_network_type remains the same. What's more, a reboot is kinda reverting things back. Would you mind for the explanation of the commands? – Jul 01 '15 at 10:48
@Arch Its working for lollipop and kitkat. This commands is used to open ur device setting.db and changing preferred_network_mode field with new values. – pooja Jul 01 '15 at 12:07
I did the both reboot and airplane mode .. I don't want to reboot device that's why AP mode used. Sleep used to make some delay. It is changing in device network options. – pooja Jul 01 '15 at 12:11

@Arch why have you not used settings put global preferred_network_mode 1? Why it doesn't work ?(I tried and it's not working) – Prajwal Jul 27 '18 at 10:59

I hope this helps:

GSM Only:

adb shell sqlite3 /data/data/com.android.providers.settings/databases/settings.db "update global SET value=1 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

For LTE, change value=11 For WCDMA, change value=2

Instead of adb reboot you can use airplane mode on/off. – pooja Jun 16 '15 at 09:36
@pooja No, Airplane mode doesn't help in my all the three devices. Only hard/soft-reboot does. – Jun 30 '15 at 11:01

ADB command to set RAT:

**adb shell settings put global preferred_network_mode1 2 --> WCDMA on SUB1

adb shell settings put global preferred_network_mode2 1 --> GSM on SUB2

adb shell stop ril-daemon

adb shell start ril-daemon

adb shell settings put global airplane_mode_on 1

adb shell am broadcast -a android.intent.action.AIRPLANE_MODE --ez state true

sleep 5;

adb shell settings put global airplane_mode_on 0

adb shell am broadcast -a android.intent.action.AIRPLANE_MODE --ez state false**
