[Q] how to force network to WCDMA only - Verizon Galaxy S 5 Q&A, Help & Troubleshooting

Hello guys !
I would like to know if there is a way forcing G900V to choose "only" modes for network like on G900F , WCDMA only , GSM only etc..
I used to do this for example with a code in LG G2 Sprint so I can enable more hidden modes ..
any suggestion ?

Yes I have found a fix around for this.
But it needs root access to work.
Are you rooted?

Need to backup QCN, EFS just incase the IMEI turn 0 (mine got turn 0 without backup, no issue for use, but backup is better than none )
After backup just flash the ZIP.

Possible to Convert LS980 to D802 ?

Please HELP!!!
can you guys please tell me is it possible to convert Sprint LG G2 (LS980) to International version (D802) firmware?
looking foward for your help.
thank you!
Yes it is possible with lots of searching and hacking. It is way easier to do permanent SIM unlock procedure and easier than that, use a custom ROM. See link:
http://forum.xda-developers.com/showthread.php?t=2655133
Here's my knowledge from the conversion. I could follow the steps in that post but the phone never really worked right. The steps to make the phone work on GSM carriers caused menus to disappear from within the phone, such as ability to change APNs. It works but there's a better way.
I flashed an AOSP ROM to my phone. Shameless plug here for LiquidSmooth beta, I've had the least problems getting a working phone with that ROM, actually works out of the box. While on AOSP, I can replace my Sprint LTE SIM with that of another carrier, reboot the phone and then go to the *#*#4636#*#* menu and change radio mode to GSM. I'm using an AT&T SIM now, domestic even and can SMS, MMS and have HSPA+ data, no LTE. If for some silly reason I want to switch back to Sprint, just swap SIM card, reboot phone, change radio mode in the hidden menu. Simple.

Thank you very much mate :highfive: ! but actually what i want is to have D802 (Stock) firmware on LS980. because D802 is getting updates so quickly. ( Knock Code) i searched for a way to convert but i couldn't find it. can you guys please tell me is it even possible? because both devices are have same hardware except the LTE band! looking forward for your advice. thank you! :good:
I know it's possible. I read once what has to be done. There's some trickery that has to be done in the build.prop which makes the phone think it's another model which would allow the flash. All I can say is search. It is on the XDA forum. The term used was CID change. Found a ton in 2 minutes all related to HTC One on Google, finding the G2 should be easy enough with search.
Once time converted, the frequencies GSM 850/900/1800/1900, UMTS 850/900/1900/2100 (3G), LTE 800/900/1800/2100/2600 (4G) it work or not?
Please someone answer this last question .
Once converted, will the converted LS980 support the frequencies of D802 ( GSM 850/900/1800/1900, UMTS 850/900/1900/2100 (3G), LTE 800/900/1800/2100/2600 (4G)) instead of the LS980 frequencies ?

Simple answer is "No" . because frequencies are hardware things. we can only change softwares. LS980 will not have D802's frequencies by anyway.

Yes there is a way to do it but I don't know, me too I'm searching for this solution, because I bought a used LS980, and when I plugged it into PC the LG Support tool ask me if I want to upgrade the software of the phone (Into Lollipop) and the actual version at that time was D80230e, I let the authorized the LG Tool to download the update, and when finished, everything goes wrong the phone became unusable, when I push in a zone it react in another, and it was really hard to achieve the first steps of the configuration, when finished I decided to open the phone and look at the motherboard and bingo I found that it's an LS980, then I downloaded the LS980 firmware, I flashed it, and everything became OK, except the lost IMEI, then I tried to resotre the EFS backup that I done before that I upgrade it with LG Tool, and then the phone stay on the LG logo...Right now my phone is out of service, I use it as camera and nothing else...I'm searching for solution every time but I found anything...Is there any solution ?
What about changing motherboard only, will that work ?

How to recover IMEI ?

On order to restore your IMEI you've just to flash your phone with the ZVD version and let the OTA updates install,then you'll recover your IMEI, but if you flash again with the ZVD you will lose it again

[Q] question for LG G2 sprint version

Dear friends, my friend bought a second hand LG G2 sprint version from olx India. The phone is unlocked already and its rooted also. But the problem is in some sims, the internet doesnt work but the network is there..(data is not working).
Will installing custom roms solve the problem?? I have done the permanent sim unlock for LS980(one thread is there for it).
Currently on:
Android Version: 4.4.2
Software version - LS980ZVC

I have already done that ..
Guess, I have to flash custom ROM now..
btw, even u r using ls980 in India ?? if so, which ROM do u prefer ??
you dont need a custom rom, just need to put the apn settings.

ya... can u tell how to do that ? there's no settings to change the APN manually .. and not only this, I cannot switch the network to 3g mode only, since there's no option for it (there are modes : global, LTE ,CDMA , gsm/umts, ..) no umts only mode!
I even tried the radio switcher app.. phone doesn't support the app ..
anyways , I have downloaded the milestone and pa ROMs .. will try both of them .. n see how it works..
I advise you to stay on stock based (cloudy's, optimus...)
_____________________________________Read more write less and be smart
GSM/UTMS is your setting for 3G it will auto switch to 3G
u don't need 3G only thats acutally kind of stupid since if u very had or low network it will force 3G network and have bad battery drain or worse no network.

LTE/WCDMA only option?

Hi all,
I recently upgraded from an S5 to an S7 edge.
Because of the way 3 manages it's network in Ireland the phone is constantly changing to GSM coverage (2G) and takes ever to switch back to 4G or WCDMA (3G) even when there's coverage.
On the S5 I had the option in device info to select LTE/WCDMA only which ensured that the phone stayed on 3G or 4G at all times, however I don't see that option on the S7 (see below).
Is this a firmware setting that can be changed?
Do any of the custom ROMs support this setting?
Any help appreciated...
Is there a file I can edit to add this option?
Anyone, anyone, Bueller?
Can any devs explain where these options come from, are they firmware settings or are these options carrier dependent, surely someone must know where these options come from?
Do you have options under settings>mobile networks>network mode?

These are the options I have under network mode and also in device settings (no option for 3G/4G only):
It appears that your carrier disabled the feature. You could try flashing a custom rom or a different csc.

Yeah it appears so. I've flashed nearly all the custom ROMs and the options are always the same. I also flashed 3 different CSC to no avail.
Not sure where to go from here. I wonder if I edited the build.prop file would it add this option?
didn't you find a solution yet? I've just tried the 4G Switch app from the play store to find out this combination is missing and developer email address is invalid... Is there an HW limitation?
I'm using the Helios Rom now and the option is there for lte/wcdma only. Happy days.

This app lets you lock 5G/LTE/4G/3G/2G bands on most Samsung phones running the latest One UI software (no root required!):
