So here are the steps I follow to use the Sprint LG G2 (ls980) with any rom on Tmobile or AT&T in the US

*This thread is specifically for the LS980. Some of the information might apply to other phones, but I can't say for sure.

***Caveats of using this phone Tmobile or AT&T:

-LTE doesn't work. Missing lte bands. Highest we get is hspa+.
-Haven't tested Custom Kernels
-instead of 4g or LTE logo, it says gsm all of the time (paid app that will safely change icons without system crashes linked below)
-Had to use 3rd party app to change radio and apn settings (see below)
-Wifi on stock 4.4.2 didn't turn on twice in the last 2 weeks when coming from a wakeup. Had to reboot to fix.

Again, I did not do any work. I have only compiled this information from various forums. Most of this work comes from cloudyfa, the find from pvinodnayak, the unlock from ysabxe and countless members in the sprint unlock forum and the old sprint build prop forum before the unlock was released. I have just compiled information. Thank op's for their work.

There are multiple ways to use the Sprint LS980 on Tmobile or AT&T. Before we get into them, please do the following:

- root phone with ioroot http://xdaforums.com/showthread.php?t=2522346

- use autorec to install TWRP
http://xdaforums.com/showthread.php?t=2715496

*If you notice now that when you screen goes to sleep, and when you try to activate the screen it shows a whole bunch of white lines, boot into recovery and install the G2PanelSwap. [/url]http://xdaforums.com/showthread.php?t=2792844[/url]

There are 2 ways to accomplish using our phone. (be sure to scroll down to the bottom to see the 2nd way. You might want to to this instead of the first way.)

1st Way - Use your phone on Stock Sprint Software

***If you are already on the ZVC firmware, people have noted problems using the following instructions..There are constant system crashes. It is recommended to restore back to an earlier version, make the changes below, then take the ota upgrade. You can go back to stock by following this guide.

If you prefer to stay on ZVC, please follow jsergio123's guide found here:
http://xdaforums.com/showpost.php?p=52915223&postcount=814


1-setup phone and Download root browser
https://play.google.com/store/apps/details?id=com.jrummy.root.browserfree
and a rar extractor.
https://play.google.com/store/apps/details?id=com.rarlab.rar

2-Download the ls980simfinalunlock.rar
http://xdaforums.com/showthread.php?t=2655133

3-extract the rar and copy the carrier contents and use root.explorer to over write the files in the root carrier folder.

4- Download Rom toolbox lite
https://play.google.com/store/apps/details?id=com.jrummy.liberty.toolbox
and use it to Update the build.prop (reboot between each. You can turn on airplane mode in the meantime to stop the system ui from crashing)

ro.carrier=spr
ro.build.target_operator=spr
persist.service.crash.enable=1

Found from this post.

http://xdaforums.com/showthread.php?p=49945052

*After trying numerous build.prop edits, I have found that they all cause system crashes. Please only use the ones listed above. If you hate the GSM icon, I have found a way to change it. https://play.google.com/store/apps/details?id=it.ptoti.g2_tweaksbox . Install it, and then buy the premium pack for $1. (cmon its only a buck.) After you unlock all features, Click on Theme Tweaks -> and make sure Enable Theme MOD is selected. Then click on Status bar. Then make sure Enable Status Bar Mod is On. Then scroll down "Change status bar's icon set" You can choose through different icons from different carriers. I prefer the Tmobile one. They will take affect after reboot.

5-Use Radio Switcher to check and set what radio to use. I use LTE\GSM\WCDMA
https://play.google.com/store/apps/details?id=com.snclabs.radioswitcher

6-Use Tweakker MMS APN app to set APN
https://play.google.com/store/apps/details?id=com.tweakker

*Note - Some users get force closes when trying to make a phone call. For some reason, you need to add a number 1 to your contact before you call

If you want to fix this manually, Follow the following fix found by jsergio123)
*To fix the issue of the com.android.phone process crashing when you don't dial a 1 in front of the number edit the /data/data/com.android.providers.settings/databases/settings.db file with a SQLlite editor and change in the "system" table "assist_dial" and "assist_dial_init_db_check" to "0". If you don't see those 2 rows then you can add them. Fix permissions, wipe cache and reboot.

Another workaround is that I have found an app that will automatically add 1's to every one of your contacts.

https://play.google.com/store/apps/details?id=com.maplekeycompany.apps.numberfixer

Install it and open it -> click Add area/country code -> change the dropdown to 10 and hit ok -> and in the area code, erase the area code part leaving just the number 1 -> Fix all. It will prompt you for how many numbers it will add the number 1 to all contacts.

2nd Way - Flash a rom

After you have Rooted and Flashed and possibly the G2Panelswap , you may want to consider installing a rom that works out of the box. It is much easier.

Here is a list of roms that work out of the box that I have personally tested. I know there are more.

***Update***
In all of cloudyfa's latest rom builds they do not work out of the box. I had to install the rom without my sim card in. Then download and install rom toolbox lite (see step 4 above) and change ro.carrier to spr (make sure its lowercase.)

I then turned off my phone, put in my sim card, installed radio switcher (link in step 5 above) and chose WCDMA preferred. Everything worked after that.

Cloudystock =stock http://xdaforums.com/showthread.php?t=2661866
Cloudyflex =LG flex port http://xdaforums.com/showthread.php?t=2618864
Cloudy pro II = Optimus pro port http://xdaforums.com/showthread.php?t=2680745
CloudyG3 =G3 port http://xdaforums.com/showthread.php?t=2783192

Let me know in the forum what other roms you find that work out of the box and I will link them here. Please remember that unless a rom specifically states it works for AT&T or Tmobile, or is a general rom that is 1 rom made for different versions of the phone, than it most likely won't work. There are lots of roms to look through in the G2 development section as well. http://xdaforums.com/lg-g2/development

Very interesting. . I struggle to do many of these and after reading thru your I find it so easy. . Thanks for your post. .

Haven't tried yet. But this is the first post I saw that can unlock LS980 with AT&T/Tmobile.
I tried the following thread, but it only unlocks internationally and doesn't work with AT&T/Tmobile..
Permanent SIM Unlock for LS980 (OTA, APN) JB 4.2.2, KK 4.4.2
http://xdaforums.com/showthread.php?t=2655133&page=46

---------- Post added at 02:52 PM ---------- Previous post was at 02:42 PM ----------

Should I just start from Step 8?
I already followed the "Permanent SI Unlock for LS980 (OTA, APN) JB 4.2.2, KK 4.4.2" thread, so I did the following extra steps "To make APNs stick automatically:", is this fine?
To make APNs stick automatically:
1. Replace apns-conf.xml in Folder /etc/
2. Delete File telephony.db in Folder /data/data/com.android.providers.telephony/databases
-------------------------------------------


6-setup phone and Download root browser
https://play.google.com/store/apps/details?id=com.jrummy.root.browserfree

https://play.google.com/store/apps/details?id=com.rarlab.rar

and use it to Update the build.prop (reboot between each. You can turn on airplane mode in the meantime to stop the system ui from crashing)

ro.carrier=spr

persist.service.crash.enable=1

Things to try if you are still having system crashes.

Set
ro.build.target_country=US

Try this to change icon from gsm to "H"
ro.build.target_operator=OPEN (might cause system ui error)

Delete lteconfigs.apk in system/app and reboot.

9-Use Radio Switcher to check and set what radio to use. I use LTE\GSM\WCDMA

Do you have to go through the whole unlocking process for those apps to work? It says its incompatible with my phone but I haven't tried unlocking yet so just want to be sure. Also is this just for GSM usage or would I be able to switch back and forth? I want to test it out before I decide to actually cancel with sprint and go with tmobile. My friend is letting me hold on to an extra tmobile sim so planning to try it with that.

Sprint blocks gsm in the US. You have to do steps 6 and 7 to have gsm unlocked. That is why it is failing for you. Once it's unlocked, you can still use sprint

Are you using root explorer, and backing out all the way to the top directory?

Also, this thread isn't meant for troubleshooting per say, it's just a list of steps that I did. If you are having problems with a certain step, go to the linked thread and troubleshoot there, as they are the real developers who did the fix.

I didn't ever see those steps in the op. They would probably help. But at any rate, yes. Each thread brought us one step closer to using this phone in the US. I kept trying over and over what step to do in what order to get it to work, and then wrote this guide. The way to listed in the op of permanently unlock is a great way to do it, I just thought dropping the folder in is easier.

Sprint blocks gsm everywhere, unless you get it unlocked through them. The permanent unlock let's us bypass that restriction and lets us use gsm, but still doesn't bypass sprints measures to block gsm in the US. The build prop changes do that. Everything else listed is just the tools I used to change everything.

When switching Roms, you might need to make the build. Prop changed again, but you shouldn't ever have to do the unlock again. Also, op updated with possible new changes to get rid of the gsm icon and shows H for HSPA . Its working well so far.

Spoke too soon. After a reboot, lots of force closes with the new TMO settings. Back to spr and the GSM icon it is....

Yes, when I try to create a folder in the top directory, it doesn't stay after reboot. I assume this has something to do with the way Android works, but someone please correct me if I'm wrong.

You shouldn't be creating a new folder. You should be finding the already existing carrier folder, and overwriting its contents.

Don't know what to tell you. You can try just the build. Prop mods starting on step 8. People have had success with asop based Roms. I have only used stock based Roms. Also, again this question would be more for the permanent unlock forum linked above.

    My tests using LS980 and T-Mob

    From the post linked above.. Build Prop Changes:
    These will show a Standered international 4G data icon for 3G/HSPA+ and LTE for LTE.
    ro.build.target_county: CA
    ro.build.target_operator: TLS

    These will show a standered international 3G data Icon for 3G/HSPA+ and 4G for LTE (Messes up settings menu pretty bad)
    ro.build.target_county: SK
    ro.build.target_operator: SKT

    For The Korean Versions that want the AT&T 4G and 4G LTE Icons or if you want to change back and forgot.
    ro.build.target_county: US
    ro.build.target_operator: ATT

    I am trying the first one right now. The CA and TLS. I like the icon so far. Data still works. I'll have to see if it crashes at all.

    brandon,

    Thanks for this mate! I've been trying to get this working for T-Mobile on the LS980 for a while. Whilst Justin's T-Mob ROM works great its still 4.2.2 and I wanted some KitKat goodness.

    Here are my results using either CloudyProII or CloudyFlex 2.2 (Awesome Roms BTW). I wanted to get it working with T-Mobile with some stability. The funny thing is that whilst going through the options for both these ROMS via Arora installer, if I chose the Model as LS980, then the camera camcorder doesnt crash (4k video/slo mo/1080 60fps all work great!). The moment I chose any other variant (D801, D802 etc) for GSM settings, and then install the CloudyBS.zip, if you chose the camcorder it always crashes.

    Ok here are my results of using different county and operator settings (note I installed LS980 variant then updated build.prop to get GSM working so that the darn camcorder would also work!)

    ro.build.target_operator: OPEN
    ro.build.target_county: COM
    =will eventually crash with a systemUI process error

    ro.build.target_operator: TMOB
    ro.build.target_county: US
    =will eventually crash with a systemUI process error

    ro.build.target_operator: TLS
    ro.build.target_county: CA
    =will eventually crash with a systemUI process error

    ro.build.target_operator: ATT
    ro.build.target_county: US
    =will immediately crash with a android.process.phone has crashed error whenever trying to go into Network Settings.

    Has anyone found a build.prop setting that never crashes with a systemui error on the LS980, AND where the camcorder works? I'm sure we can find it if we put our heads together!!!

    Great news! I ended up going to complete stock, then flashing the CM11 for T-Mo on Sprint (http://xdaforums.com/showthread.php?t=2639165), then flashing the latest Omni Nightly from there, then changed the build.prop (had to add to of the fields), then used radio switcher, and voila! It was stuck in 2G for awhile, but it finally caught onto HSPA+. So glad I finally got it, I enjoy Omni much more than CM, and this version seems to be quite stable. Thanks to everyone for their knowledge on the forums.

    Or
    ro.carrier=TMO
    ro.build.target_operator=TMO

    Thank You, left mine to OPEN and had the H icon (HSPA+), the lowercase spr gives GSM symbol, changed ro.operator to TMO, I use Simple Mobile, so set ro.carrier to Simple Mobile, a T-Mobile MNVO, this gives me the 4G icon and increased mobile net speeds!! I am still on HSPA+, its just the 4G icon, but now getting much faster speed tests, Thanks Again!
    Also in the build.prop, set ro.telephony.default_network = 3, for default GSM auto (PRL) or 9 for GSM/LTE/WCDMA
    this will make the phone boot up GSM enabled, I had the problem with it wanting to revert back to sprint/cdma, this fixed that! Best of Luck All!

    I recently bought Lg g2 ls980 but there's no option to check software updates :-/

    Sent from my LG-LS980 using XDA Free mobile app
    Then it was probably modified somehow. Reflash it back to stock
