can ZVH be sim unlocked?

I am living overseas and my Sprint phone had a T-mobile sim card.
After arriving is not working decided to update to zvh since I believe it may have to do with roaming settings.
After flashing ZVH stock thru TOT I lost my international sim unlock.
Since the phone says I have a invalid SIM the activation is not working and I cannot do UICC unlock.
I tried using simfree and other unlock methods like copying the telephony.db from the unlock files but it does not appear to be working.
Any idea what are my options? Do I have to downgrade?

Need help unlocking LG G2 LS980 flashed to boost mobile.

Hey, I just need someone to point me to the right direction.
I bought my LG G2 off ebay last year, it came flashed to boost mobile. All I need to do is flash it back to sprint and unlock the GSM on the phone.
I just found this forum and don't know where to start in this process..
Im on 5.0.2
Software version LS980ZVI
Model # LS980
Thank you if you can help

this thread has everything you need

After you install TWRP successfully but before you unlock the sim card, You can install the latest version ZVI that is already rooted

for unlocking the SIM card I would use this procedure instead

Thank you !!

Since you are on ZVI already, you could try the steps in this thread

Hey I did all the steps and got it unlocked but I cant to get my simple mobile sim card to work.
When I select the network mode global I have full bars, but when I try gsm/umts all my bars go away.
The phone is reading the sim card, but im not able to make calls/text. I Also get a authentication error when I try to update the prl/profile settings

did you do the twoclick procedure to unlock the sim card?
did you edit your apn? from the dialer, dial ##3282#
i am on freedompop so i changed my apn to freedompop.foggmobile.com. Simple mobile might require it to be mvno.att.net or something like that( i used that for airvoice).

Yep I did the two click method but on both of my sims my phone refuses to connect/ find networks. I get emergency calls only.
I used a freedompop sim too and changed my apn to freedompop.foggmobile.com. but it still wont connect to the network. When I go into the freedompop messenger app it says. I dont have any data.

that;s strange. It worked for me as soon as I added my APN. Does your phone see the APN for three.co.uk and 3hotspot when you have the freedompop SIM in there?
I don;t even use the Freedompop Messenger app. i just use the sim for data. i can test the functionality of the sim slot because I have a freedompop CDMA/Sprint sim card along with a GSM one.
there are a couple of other ways to unlock the sim slot-they're all based on the same way so don;t know if anything will be different. there is a simfree.exe and there is a thread by someone named summercat for a 1 click procedure. try one of those

yep thats the first apn I see "three.co.uk"
im gonna tot back to zv8 and try this one more time or im just gonna go with ring plus or ting.
But thanks for all the help.

And you used ##3282# to add the new apn, correct?
I would go down to zve, then do the Ota update from sprint to zvg or zvh, then do the unlock and root and sim unlock. It's worked fine for me on zvh and zvi.

Yep, I enabled the lte/cdma, rebooted, then enabled gsm, rebooted and I got it to say freedompop on the lockscreen but after a couple of min. It went back to searching for networks.
im gonna try zve to zvg with the two click method

Good luck. The way you know it is supposed to be correctly installed is that your boot animation changes for the yellow sprint spark animation to some swirly wavy rainbow. The carrier image gets swapped to a gsm version.

no network available. only getting AWAYs

as the title suggests, i gotten the lg g3 from a guy off kijiji. He was with virgin mobile its d852. i payed to unlock the network and put my WIND sim in. I unlocked the network when there was no sim card. I put my sim card in but the only available networks i was getting is all away.
i swapped the sim thinking it might be that. no luck. i checked to see if this was blacklisted, it wasnt.
im running on cm13.
could this be because the bands are not activated? IF so, i tried following this guide http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059 but it didnt work. i couldnt get the right driver to show up.
Also could it have been impacted by unlocking the network without the sim card in yet?
if someone can help with skype to speed things up for live debugging that would be greatly appreciated. you can add me at [email protected] for skype.

update: so i called wind to see if they can register the phone as on the network and they said they cant put the imei on the account. what does that mean?

Wind needs d852g... Not d852... There is some old threads of people converting the rom and modem to d852g which unlocks the band required for wind.... Search for that, no idea if it works or not tho
Sent from my LG-D852

i had a g3 before and it was d852 and it worked fine...
like i said its d852. i couldnt even flash d852g in.

swapped sim cards with a friend who is also on wind and my g3 couldnt get service but my sim card worked fine on her phone.

another update flashed 852g firmware on my 852 no change. i did so with 852g firmware and 852 dll.
i also flashed 852 tot with 852g dll and still no change in network.
called virgin mobile and they see that the imei is no longer on the account.
this is such a pain does anyone have anything to help??? is there an easy way to view all the bands the phone currently have??

anyone??

You'll need to flash the 35b bootstack before you flash the ROM for things to work properly on 47a(not sure about jasmine). Read bullet point 5 for a link for the boostack... https://forum.xda-developers.com/ve...t/vs985-46a-stock-flashable-firmware-t3304365

did that.my phone started acting up that my sim was searching for global setting while on 47a for over a year,was giving a suggestion to tot back to stock the start over at 10b,my problem is whether I tot or kdz as soon as I root with stump(from xda site) I get sim non readable and searching for settings.this happens well before I even get to bootstocks,or ROMs.this is while trying to get it rooted on 10b,I've read many people are having a problem with sim cards..obviously tot/kdz gets me to stock with no problem,but trying to get from 10b upgraded is where the sim acts up..

as of now,it works and doesn't work.nothing to do with bootstacks,as I'm on 47a and it didn't work,I rebooted and it did work..then 2hrs later it screwed up again..not sure what it is....

download network settings guru apk and choose bands or *#*#4636#*#*

maybe your problem is something else...

OK...I really need to read more gooder So root is killing your signal somehow. Strange...
Can you grab some logs and post them please? Maybe a log before root when things are working, and one after root with a toggle of airplane mode a couple times to see if it kicks an error into the log and hopefully provide a lil info.
Also, does anything in the "about phone" settings info change after you root/lose service? For ex: unknown baseband, no imei, etc.

yes that's the main problem,I lose ime as well as phone number,and the phone says no sim card,and searching for global setting..if I reboot I may get sim card working but 9 out of 10 times the phone sim is unavailable.example is today,all day the phone worked great,then all of a sudden it lost sim card,no imie,phone number..after pulling battery and rebooting 3 times its working again.I'm on rooted 47a.

+1 For network signal guru, I had to unlock the other bands using that program. It took a few minutes.
It seems that the Verizon variants soft-lock the radio bands.

update this morning,when turning on my phone,it reads sim card searching for global settings,after pulling the battery it reboots and reads sim found,search for settings,global found,and phone works normal??, now if I tot to stock,phone is normal at 10b,then root,twrp etc and sim card will not read,after pulling battery it reads sim searching for global settings,4,5 seconds and phone is OK,then bootstacks,47a and lose sim,then pull battery and go thru the exact same thing,now I've gone to Verizon when sim is unreadable and with a new sim I still get unreadable sim,with no imie,no phone number??...

But when insert metro pcs sim card I could not get data working .Also if I factory reset my phone and run unlock app again it said my is locked
Any help please

With a Metro Sim, you need to call Metro to switch it over. It's not automatic with them.
EDIT: ALso, you need to change the APN settings for Metro to get data

You're lucky. Anytime you switch sims or put a new sim in a phone, you have to call MetroPCS. I've never been able to just put a sim in an unlocked phone or even a different METRO phone and have it work immediately. I have always had to call.
