LG G4 Sprint SIM / Network unlock

[leond]

Has anyone been able to SIM / network unlock Sprint variant of LG G4? For international use? for domestic carriers?
The phone appears to be locked. I tried putting GSM micro SIM and putting phone in to GSM mode. Got an icon about invalid SIM in notification tray. But no prompt to unlock. Also no menu in settings to unlock via network like my note 3 had. Even worse, no menu to select GSM Network operator in the settings.

if you are in US i think you can call sprint and they will unlock your phone for free.

I know , that is the theory, I am curious if anybody actually tried it. I am concerned about the fact that I don't see a menu to select GSM network, which was there in Note 3
it almost looks like the phone can roam on GSM network using Sprint SIM, but all the menus that would allow presence of different SIM where removed.

that option is just hidden, when someone get the phone unlocked the option in the menu will be enabled, are you inside USA

I did try a Simple Mobile Sim and it worked just fine. Have you tried any of the movs from Att or Tmobile??

Friend called Sprint and they unlocked his phone OTA. Now when non-sprint SIM is inserted it no longer complains about invalid SIM, however it will not connect to any networks in USA and still no way to see a list of networks or do a manual selection of network. That menu is still missing. I suspect the phone will now work outside of the USA in automatic network selection mode only, which may not be a good thing some times.

Doesn't matter what you try, you cannot use Sprint's phone on AT&T T-mobile here or any US GSM carriers. When sprint unlocks it for you, then you can use it outside of US on GSM Networks.

You must be new here. Domestic gsm has been unlocked on most modern Sprint smart phones. Just in the years I've been with Sprint ive unlocked the Moto Q, G2, S4, and now the G3 for ATT and straight talk. Ive read of several others having the same ability. The s5 can also be unlocked but only one guy knows how but you gotta pay him for it. Kinda ****ty but it actually works.

Any chances of unlocking when outside US? I got my phone from Amazon and got it shipped in my country. Tried calling them but they said they only unlock activated phones. Also tried various sites that offer unlock codes but since G4 is not asking for unlock code, they can't do anything.

Do I have any other options?

For those still trying to unlock, I've followed this post for unlocking the G3.

http://forum.xda-developers.com/sprint-lg-g3/general/sim-unlocking-ls990-zv8-t3083567

And I can now accept calls, will try it out some other time if I can get data as well.

Note: Make sure you have the correct permissions on the files that you'll copy.

will this work for at&t?? on just international?

I can't confirm, since I don't have access to any AT&T SIM at the moment. If you're already rooted, you can try it out, but make sure to back up the files.

Another update: After updating the APN, my data finally worked. LTE is impossible at the moment since the this doesn't support the LTE bands here in my country

Warning: Don't try to disable auto activation for now. I got the Security Error and still on the process of fixing it.

I also got the unlock code from Sprint. But I can't get the phone to ask for the unlock code. Any hints. Can I force it to ask?
