No. The app only is a shortcut to as what's already on the phone to change settings and nothing more.

The latest update it's patched. Only work around is a remote unlock
[LG V20 Questions & Answers] RickyShade:
Dang, so I guess further updates will be a roll of the dice :( Thanks for the info!
[LG V20 Questions & Answers] kiddPREMIERE:
ok so my phone was unlocked using this method which i actually payed 15 off ebay and i downloaded the newest update now its patched and relocked is there any way i can downgrade my software version back to V7 so i can use this method again?! If NOT what would be my solution?! help needed asap.
[LG V20 Questions & Answers] hyelton:
I'd suggest asking for a refund if you paid for this method as it's free. I'm sorry that's happened. It's sad that people do that.

Sadly no if you updated. You'd have to pay for a remote unlock to get it unlocked again.
[LG V20 Questions & Answers] kiddPREMIERE:
It was too long ago for a refund and yes it is sad that people profit from free methods but I guess it's my fault for not doing my homework. Any suggestions on a trusted source for remote unlocking?
[LG V20 Questions & Answers] RickyShade:
IMEI check results say Whitelisted and eligible for Activation BUT also says "Financial Eligibility - Device is not eligible for resale (financed)."

UGH. With these results, I'm guessing the phone wasn't unlocked in any other way than this method!
[LG V20 Questions & Answers] HD2FORNICK:
The hidden menu app will not work if you go through updates. However, I found a remote service through which I got my Sprint V20 unlocked for $19. After this unlock, this phone does not show me the Sprint stuff like UICC Unlock, etc. It's gone. Evern when I do a factory reset the phone is not recognized as a Sprint device.

Some things to note are when I was using the "Hidden Menu" app, I was getting LTE but after remotely unlocking it, I only get 4G for what it's worth.
[LG V20 Questions & Answers] hyelton:
I think you may be confused about LTE/4G. Did you check under settings and status?remote unlock changes build.prop I believe in return changed your data Icons. Remember if your seeing 4G at the top of the phone that could mean LTE as most countries call LTE "4G" confirm by checking network status under settings.
[LG V20 Questions & Answers] HD2FORNICK:
Believe me, Ebay is very particular of theft and will revert ALL charges. I paid $5 for this same app and got a refund. I did it on principle and I know $5 is not much. Contact the seller and let him know he sold you a free app and simply ask for a refund and if he doesn't agree, threaten to get ebay involved and paypal. I am certain you will get this refund.

---------- Post added at 09:01 AM ---------- Previous post was at 08:55 AM ----------

Yes, you are absolutely right, as always! :o

The Network status does say LTE! I should have checked that first. But, can you tell me why after this unlock process I do not see the Sprint UPdate portion in my settings anymore? I cannot find the UICC Unlock, etc anywhere.
[LG V20 Questions & Answers] hyelton:
That would also related to a build.prop change if that's what's going on. Im not sure but the change in data icons are one sign that the build.prop was changed. If it's changed away from Sprint. It will remove any Sprint features, data icons , etc. They may still be there but there's no direct access to them.

They could be doing something else with the firmware. But I do know changing build.prop will do that.

I do know with past phones like the G3 updating will break remote unlock.
[LG V20 Questions & Answers] HD2FORNICK:
Wow! I was told that the unlock is permanent in spite of updates, etc!
[LG V20 Questions & Answers] hyelton:
It may be now. But before it wasn't with older models.

I am on software ver ZV6 and was using this app to unlock my phone. I have purchased an unlock code from an online vendor and would like to use that to unlock my phone so that I can update my software beyond this point. How do I revert back to stock settings so that I can enter this code? I have tried changing the settings back to Production and have even tried doing a factory reset but I cannot seem to get the prompt for entering this code. Thanks in advance for the help.
[LG V20 Questions & Answers] HD2FORNICK:
My response only applies to Sprint V20. I don't think you need an unlock code as this phone will not ask you for it. Either Sprint has to unlock the device at their end or you get it remotely unlocked like I did. Quite frankly I don't think the remote unlock is permanent either as Hyelton mentioned it is a possibility that the remote unlock could lock itself again after a FW upgrade.

This is why I am never buying a Sprint phone again. Too many hassles! :rolleyes:

You need to change sim cards before you will be able to change options. The SIM is what has caused the option to disappear.

The same thing happens again.

I can't access the *#*#4636#*#* hidden menu. The phone does this and after some time returns error.
[LG V20 Questions & Answers] getoffmeluckycharms:
You need to use a Sprint SIM or an AT&T SIM or something like that. It's the specific SIMs that you are using they are blocking the option. It's because of the country code of the SIM.
[LG V20 Questions & Answers] hyelton:
To get rid of the activation you need to ##RTN# and use the SPC code to factory reset it. (Not sure if that affects remote unlock though)
[LG V20 Questions & Answers] datrmon:
How do I get the SPC to reset the phone
[LG V20 Questions & Answers] datrmon:
I have done it and yes.I lost the remote unlock(it now shows invalid sim). Guess I have to look for a reliable permanent unlock for the phone.

Anyone who has successfully gotten his LG LS997 unlocked?

I was able to get my SPC though this thread. Worked like magic
[LG V20 Questions & Answers] hyelton:

UICC unlocked by sprint, but still does not work on gsm

I have my lg v20 ls997 UICC unlocked by sprint, but still does not work on gsm.

Called sprint and talked with the tech depart, no help at all.

Now when you insert att sim, it shows no sim card, no network.

I think sprint set some kind of software trick to make sure that you can not use ATT or other domestic carriers' service even if they unlock your UICC according to law. I guess, the highly paid in-house lawyers in sprint worked together with software engineers and carefully designed the trick to work around FCC regulation.

The hidden menu app posted here is no longer working on the updated LG v20s. see the attached screenshot. You don't even see the options anymore.

If anything still works, please go to FCC website to file complaints.

Hello everyone!

Reading all messages it's very confusing for person who is not familiar with all that stuff. All I need to do is make my LG v20 (997) Sprint ready to be used on gsm networks (well basically everyone wants to do that)

I'm running latest software LS997ZVB. Will initial instructions (first post, installing app and switching to other networks) will still unlock the phone?

Please if anyone can give simple plain instruction what I need to do. I really appreciate if anyone could assist me.

Thanks
[LG V20 Questions & Answers] hyelton:
No the app only works if you haven’t updated. Read the post right before yours :P

Anyway you would have to buy a remote unlock somewhere like on eBay. But keep in mind it won’t function no where near as good as an actual GSM V20 service wise.
[LG V20 Questions & Answers] HD2FORNICK:
There are services on Ebay that will unlock for you remotely. I used one such service and the phone worked well on GSM carriers but it removed all traces of Sprint from the phone like UICC unlock etc. I believe this unlock service makes the phone Sprint incompatible unless they do a remote reset or something.
[LG V20 Questions & Answers] lucia758:
better if you get a gsm lg v20 .....i have a ls997 and i got it unlocked and the signal drops every couple of seconds and i doubt it is hardware problems. My software version is LS997ZV9
[LG V20 Questions & Answers] Zachary1984:
Thank you guys for the replies. Based on that, I tend more not to deal with this and just gets sim free devise... Perhaps new One plus 5T.

Or still risk and do remote unlock thorough eBay? Any suggestion where else, maybe we have someone here on this forum? Big caveat on ebay I think, they all want you to have PC windows, to install software (for shared screen I guess). But I'm on Mac :(

Recently bought a Sprint V20 firmware version ZV6. So this method to unlock and use on AT&T should work ?

[LG V20 Questions & Answers] semifast:
I was able to get Tracfone AT&T working but not Freedompop lte which is just ATT data.

As far as going back to being ready to activate on Sprint is a factory reset sufficient ?
[LG V20 Questions & Answers] hyelton:
You set the correct apn correct? You have to do that before data will work...

##RTN# to reset. But if you bought a remote unlock no clue if it will work on sprint after that
[LG V20 Questions & Answers] semifast:
I didn't buy a remote unlock, just used the instructions here in this thread. and in the similar thread about the LG G5 which has a few more step. It worked because my V20 is still on firmware ZV6.

Everything works fine on AT&T, voice, mms, data. Yes I did set the apn and it works fine using the Tracfone ATT sim.

I mostly need more info about making it ready to use on Sprint in the future. I'm a bit unsure about when I need the spc, or if I need it ? What happens when I enter ##RTN# ? Does it prompt for the spc at some point ? The phone isn't associated with an active Sprint account..can I just ask Sprint for the spc when I call to activate it or do I need to get it prior to that ?

I'm happy with it on ATT for now but I like to know how to restore it to Sprint ready while you or someone is still following this thread. :)
[LG V20 Questions & Answers] hyelton:
Sometimes some carriers APns will auto input. But FreedomPop usually won’t so if you didn’t setup the apn that explains why it didn’t work.

Yes by dialling ##rtn# you’ll need your spc code. But obtaining it can be hit or miss. You might get a rep that’ll give it out, you might not it’s hit and miss.
[LG V20 Questions & Answers] HD2FORNICK:
I am assuming you used the APK in this thread to GSM unlock your Sprint device right? In that case you can easily undo as per instructions and go back on Sprint. Remember this APK does not permanently unlock your Sprint device. Also I believe the moment you go over ZV7 this APK becomes useless. Your best bet is to get UICC unlock from Sprint.
[LG V20 Questions & Answers] semifast:
when you say"per instructions" do you mean undoing the instructions one by one or do you mean doing a ##rtn# ?

As it turns out my V20, purchased used, is already unlocked according to Sprint chat so I didn't need to do the hidden menu method.

So my primary concern is undoing what I did and getting back to where the phone was before.

Just to share my experience . . .

I tried the method described in the OP using a Sprint LS997 with zv7 firmware and a sim card from a Tmobile mvno. Voice and sms worked fine, but I could not get any data service at all. I did set the APN correctly. I got the same result with the network mode set to "Automatic" or "GSM/UTMS". I was not able to do a factory reset on the V20 to see if that would help. (It's not my phone)

I also tested the sim card in my officially unlocked AT&T phone, and it worked fine and received LTE with the same APN settings, so the sim card is working fine.
[LG V20 Questions & Answers] semifast:
short version--I want to know if the hiddenmenu.apk could cause this...my Sprint V20 won't make phone calls if it has an LTE connection. I have to manually go to the phone's settings and put the "Network mode" in "CDMA" instead of "Automatic" or "LTE/CDMA".

long version--I was able to use the method in the OP to unlock the phone and use my Sprint V20 on AT&T. It worked fine because my V20 still has older firmware. But I then wanted to start using it on Sprint so I did a ##RTN# to reset it. This worked to except for the one issue I describe above.

It could just be a problem with the phone or old firmware, but I want to ask if my using the hidden menu, did I mess something up ? Is there a different kind of reset I need to do ? The phone is not rooted, I do have the msl. Thanks.
[LG V20 Questions & Answers] hyelton:
If you did ##RTN# it resets any changes that where made in the hidden menu. It may be something up with the VoLTE settings if there’s any. Doesn’t sprint have that? Are you using it directly on sprint?
[LG V20 Questions & Answers] RickyShade:
Are you using "GSM/WCDMA/LTE auto"? This works for me on Cricket.
[LG V20 Questions & Answers] hyelton:
He’s using it on Sprint which is not a GSM carrier so that would most likely cause more problems.

Oh yeah. I saw V20 on AT&T and just went in from there, didn't register the switch back to Sprint. Ewww LOL.
[LG V20 Questions & Answers] semifast:
Yes I'm using it on Sprint. I was thinking it could be something like Volte compatibility which might require newer firmware than ZV6 but I don't want to update it in case I go back to a gsm carrier.

Just wanted to be sure I had eliminated any problems with what I did by doing a ##rtn#. Thanks again.
[LG V20 Questions & Answers] vlad48:
Short version - on Sprint there is one hidden mode which is called "Global" (it is not accessible via standard Mobile Netowrks/Network Mode menu).

To force this version on via hidden menu (up to ZV7) you should go to:

Field test-->NAO Test -->NAOT-->NAO Setting--> switch NAO Test Toggle to enabled-->NAO carrier SPR and restart --> if you are not using SPRINT SIM you will get Sprint GLOBAL operation mode.

I supposedly got my Sprint LG V20 unlocked through LGSimunlock.....but as mentioned here in previous posts it never connects.....signal drops.....sometimes can call other phones, but cannot call this one. I live overseas in Saint Lucia and called Sprint. They said that the phones needs to be on Sprint service for at least a year before it's TRULY unlocked. And that it will work flawlessly Sprint there in the U.S., but not overseas. I cannot get the UICC unlocked, nor is there any place to put the local APN here on the phone since it's version now is LS997ZVD. Is there anyway to revert back to version 7 or 8 to be able to install the HiddenMenuCall app? Any help would be greatly appreciated

You cannot downgrade due to antirollback. The service issue is common more especially in lower signal areas. There’s no fix for that for sprint devices being used on gsm carriers.
