irbaaz · Apr 30, 2014

HI,
I am using ls980 on android 4.4.2 unlocked

1. I want to put my phone on GSM only mode , i tried everything nothing seems working neither any app from play store is working , I am rooted.
2. Can I downgrade or upgrade my phone and still have phone unlocked ( i bought it unlocked and dont have code to unlock it again )

whats up man, try this out, go to settings
tethering & networks
Mobile Networks
Third one down should be, Network mode
open network mode, set GSM/UMTS

I wanted to note, I edited my build.prop, ro.telephony.default_network = 3,
I have advanced signal status installed from the playstore, set to GSM auto (PRL)
My Preferred network mode: GSM/WCDMA according to the phone. Best of luck!!

Advance signal syatus under phine information giving your phone is not supported

How to do gsm only?
Is editing build.prop will do the trick?

Cronic2009 · May 1, 2014

yes editing the build.prop, default_network will make the phone connect to GSM auto (PRL) upon boot up

Yes, just set it in the build.prop, yes 3 will give you gsm/wcdma

i have done it and it's now showing WCDMA Preferred in the network menu. but what about sign it's only showing GSM on the notification panel not showing 3g or anything and also tell me how to know if my internet is on 3g or 2g ? and what is the number of WCDMA only not WCDMA/GSM ?

For gsm only number is 3 but in network it will show wcdma/gsm but you must be on gsm only , check network under about yo see which network you are getting

Tell me what steps you did if you got success without bricking your device

ro.telephony.default_network
0 = WCDMA Perfered
1 = GSM Only
2 = WCDMA Only
3 = GSM/WCDMA (auto mode, according to PRL)
4 = CDMA / EVDO. Perfered
