How to unlock with ls991zvb version? Would downgrade to zv6 still work?
[Sprint LG G4] mayrer:
no, ZVB no downgrade.
[Sprint LG G4] mayrer:
No other variant fix this problem, if itson=disable phone must work. Sorry :confused:

[Sprint LG G4] justforgot:
My current software version is LGS991ZVC can i downgrade to unlock or no?
[Sprint LG G4] Phantisy:
ZVB and up cannot be downgraded to a rootable version. So the answer is no for you.
[Sprint LG G4] justforgot:
So i guess that also means no to Un-locking process as well. ****.
[Sprint LG G4] Woody Herald:
There is hope you can unlock it but I haven't figured out how to get data yet or change APNs I have a Sprint ls996 also a ZVB version not really sure how this whole thing works I don't even know what I did but I know I did it I'm not exactly sure how I did it I have to double check my own work before I could give you the information but there is hope
[Sprint LG G4] TheMadScientist:
Just tossing ideas. So i know u can dd command the rom just not rooted on zvb rite.

Hi, I have sprint LG G4 running on ZV5. If I unlock sim by the described method will the unlock carry forward with zv9 & further updates ? (ie zvb/a/c or probably nougat ! )

[Sprint LG G4] TheMadScientist:
no because that ones im assuming thats the att version they employ a nck code or network unlock code and from first glance buying a unlock code online is all u have to do put in a invalid sim and then enter the code. theyre network locks are a little diffrent than what we use on sprint lgs because they are naturally a cdma phone so they dont employ said nck lock code system
[Sprint LG G4] TheMadScientist:
Here ya go
[Sprint LG G4] Woody Herald:
Because that are per say thay already unlocked all we do is change the carrier not the operator
[Sprint LG G4] TheMadScientist:
well they are locked but programed with sprint tower info what were doin on lg is basicly telling it to pull carrier info off sim card instead of nam prgraming. utilizing the sprints lte only sim card port to pick up gsm carriers

[Sprint LG G4] nattn:
Hi Mayrer,

You're awesome..my LG G4 Sprint zv5 work perfectly..CDMA and GSM also LTE band 5 everything works! :D:good: Thanks..

I also have methods to enable diag mode without spc/msl that works in g4 Sprint zv5. and of course I will inject my G4 Sprint to my country cdma carrier. If anyone who wants to know my method to enable diag mode without spc/msl,just wait tomorrow...thanks.:)
[Sprint LG G4] mayrer:
no problem)

To enable diag mode spc/msl not required :) or do you require? :eek: strangely...
[Sprint LG G4] ggoomani:
I am also curious if this method allows full use on T-Mobile as well (for LS991). I have a LS991 that was supposed to be unlocked by the seller, but I have been seeing conflicting information in the unlocking only works for international or if it also works with US gsm carriers as well. Thank you
[Sprint LG G4] mayrer:
No one has tried to t-mobile, but many people use gsm in europe without problem.
[Sprint LG G4] Phantisy:
Seems to have worked for me. i cannot test on another network at this time but I will as soon as I can.
[Sprint LG G4] nattn:
In G4 Sprint ZV5 when you press ##3424# to enable diag mode,you have input Service Code(msl/spc) first..that's why you cannot enable diag mode in normal ways,you have to know the spc/msl first to enable it.
[Sprint LG G4] mayrer:
strangely... On my g4 sprint via ##3424# diag enable without msl.

then i plugged it to pc and through cdma workshop learned msl.
[Sprint LG G4] nattn:
Maybe your spc has unlocked (000000)..mine not..
[Sprint LG G4] mayrer:
now my spc unlocked, but where my spc was not unlocked, diag mode also switched without spc :angel:

On lg g2 sprint i enable diag whitout msl with shortcut master.

[Sprint LG G4] kneegross:
I get all the steps except: 5) Change permissions for files node.db and node.db-journal is rw-r--r-- (0644)

How do I go about changing the permissions? The picture attached does not show up. If I can get this step, I can test if this works on T-Mobile for you guys.
[Sprint LG G4] kneegross:
Works on T-Mobile

Hey guys, please ignore my earlier post, I figured out how to change permissions in ES File Explorer. I didn't realize I didn't have root explorer ticked in settings.

T-Mobile works at 3G Speeds! I'm getting about 5Mbps down/up. I can do everything from calling, texting and browsing the internet. However, MMS doesn't work and APN settings are still greyed out.

Any idea on how I can get the APN settings on? Maybe I should do a complete factory image wipe and start from there as I did buy this phone second hand and the guy told me they tried to get it unlocked.

I have the Sprint LS991ZV6 and I'm using it on T-Mobile.
[Sprint LG G4] mayrer:
If you perform step 5) the apn settings will be active...

Try this:

Open shortcut master, press "menu" and press "search" , in search field enter

vzw_only.apnsettings

and press "search", after search press on one result "Hidden Menu".

This hidden settings, for add apn press Menu(long press on button recent apps) and press "New APN".

Can't establish wireless data connection

Any solution for my problems?

Many thanks guys.

2) Flash to ZV5 TOT and rooted ZV5 ...Unable establish wireless connection..SIM Unlock not work...no internet just call & sms

Thanks friend.

Have you tried this unlock and it not helped?

It should work on zv5 and zv6.

Sorry for my English, i'm from Russia.
[Sprint LG G4] adrs168:
Yes this unlock works perfect when ZV4 then flash TOT ZV5 then OTA ZV6 then not worked anymore...
[Sprint LG G4] mayrer:
Open dialer and enter ##3282# in new window press APN settings after press menu and press Reset to default. if it do not help, I added to guide apn settings, try this.

I advise you to contact your operator, perhaps settings lte is wrong.

After flashing zv5, lte worked?
[Sprint LG G4] melvinchng:

I am going to state this to those who are interested. I confirm.... I say again.. I confirm ATT service works. I am getting LTE as well here in NYC. I have cricket but LTE works.

I followed the instructions as mentioned in the post. I also saved the backups as a precaution. Running UltraPop with ATT rooted
[Sprint LG G4] dada2j:
I tried both but no signal. When I dial it just says out of service area. Intially it showed invalid sim but after I followed the instructions I don't get the error . When I search for signal I see att and T-Mobile if I try to connect it says cannot connect voice is disabled.

[Sprint LG G4] SD2014:
After many weeks of trying different methods, including this one in October, I tried this again with the updated apn instructions. My phone now has 3G and can make calls and texts without issues. Thanks!!!!

For those of you having problems getting the apn settings enabled using the opening post, see also post 34. Use the shortcut master method to access apn settings and long-press menu (square) button to reset network. This solved the no-data issue for me!

Thanks again, Mayrer!!!

Working on rooting my ZV6 right now.. Will report back with how it goes.
[Sprint LG G4] slyii:
I followed this guide to the letter. The only problem is that my LG G4 doesn't have "settings"=>"roaming"=>" menu.

I installed the international rom, this one: http://xdaforums.com/sprint-g4/development/rom-lg-ls996-zv6-international-fix-t3234195

And once i set up the APNs I dont get any data.

I also went back to stock then installed Ultra Pop here: http://xdaforums.com/sprint-g4/development/zv6-ultrapop-rom-v1-2-ls991-g4-t3211725

But again, no way to set up apns, there is no roaming section in the settings.

At the end of the day all i can do is call and text. I am testing this with an American T-Mobile simcard.

If anyone knows how i can get data please let me know.

Thanks in advanced.

Already read the whole thread, including that post.

If i go to that hidden menu, click reset to default and select T-Mobile from the options shown, it selects it, but once i leave that window and come back, non are selected. I also tried adding a new apn from scratch and selecting it. Again no data.

Already did a clean start about 3 times, followed the steps slowly, read the whole thread, followed what ever tips anyone left. Still no data.

PS. the phone does have a good imei, it isnt being financed or black listed. Like i said earlier, calls and text work

OK so I followed the guide to the letter. I am on ZV6. When I reboot for the final step and insert the SIM Card, nothing happens. It is like it's not Unlocked. I will post some screenshots later since I'm going to bed now.

[Sprint LG G4] nexendz:
If you go to settings and change from global to GSM/UMTS and send a sms it will work after you send a sms switch back to Global and you'll have LTE again and still be able to send sms, but if you reboot you have to redo the process, I was having issues with sms not working, tried everything from different apns to factory reset and flashing with tot file.

Steps:

Mobile network > Change from Global to GSM/UMTS > Send a text message > Switch back to Global mode.

*also if your mms doesn't work afterward check the APN, mine gets changed to sprintmmsc so I have to put it back to my correct one and afterwards both sms and mms works fine.

Unlock problem,

Hi guys,

I used to unlock it by this method,

But now, I flash my G4 to ZV9 aka Marshmallow 6.0 and it locked again!

I tried to flash it back to ZV6 but it was soft brick every time i tried, and now it's on ZV9 for good. But the thing with ZV9 is I can't root it by any way so I can't unlock it, now my phone is no more than a music player running android.

Anybody can help me get through this? I tried to flash it back to ZV6 by Flash Tools but even I use stock rom or cook rom it was soft brick anyway. Any resolution?

Thank you very much.
