It doesn't work with mine, I've got LS991 ZV8 6.0 , pls help me! thank you so much bro!

---------- Post added at 02:51 PM ---------- Previous post was at 02:44 PM ----------

Thanks bro! I am still looking for the way to root LS991 ZV8 6.0 to avoid becoming brick.
[Sprint LG G4] KingFatty:
How did you get ZV8?

Are you sure yours is not working - you can get that error message even if it's working, because you are connected to the cell tower in the wrong wireless way, I forget the details. But if it's just not working, then maybe you didn't "save" the settings, because you have to hold down the square button for a bit and manually select "save" after you edit to add ",dun" in the info.

Maybe walk us through the steps you took so we can see if something is amiss...
[Sprint LG G4] lnguyenvn2003:
After I bought the unlocked GSM LS991 at Huca.vn in Vietnam but it wasn't rooted yet, some days after, I got an uptate notification from ota, then I continued to update my phone and it became LS991ZV8 6.0. The problem is I can't edit from APN, it's blur with words "ota-otasn". My English is not good, I don't know whether you understand
[Sprint LG G4] KingFatty:
Anyone get this to work on the most recent over-the-air update to ZV9, Android 6.0 Marshmallow?

When I click on the "try" in QuckShortcutMaker for Service Programu, IOT Hidden Menu, it's like Yoda saying there is no try.

The actual error message is: "Sorry. You cannot launch this activity from this app because it requires some additional permissions to launch."

So is there a way to grant those permissions, or is there an alternative to editing the APN info to add ",dun"?
[Sprint LG G4] boraxman:
Yup locked out now with Marshmallow....Heres hoping for the workaround.....
[Sprint LG G4] pelon90005:
I pledge $20 usd for a fix on marshmallow. I've tried the nexus 6 hack by editing the build.prop or pushing an adb comand and could not get it to work.I've also tried getting into the apn settings using my msl code and could not figure where and what to change, as the menus have changed from the previous lollipop setup
[Sprint LG G4] daddymikey1975:
I had the lollipop hack before switching to MM. I can confirm that I am still able to use Hotspot free after upgrading to MM.

Not sure if this is an anomaly or not...
[Sprint LG G4] Ryangene:
Anyone have this trick with the Nexus 6p and I'm on Sprint. -Thanks
[Sprint LG G4] boraxman:
After reading your post again I flipped the hotspot switch and mine also still works after the MM update so it must have held the ,dun edit.....for now anyways.
[Sprint LG G4] pelon90005:
Interesting..I was on rooted, then flashed back to stock then updated via ota zip. I lost hot-spot though. I'm wondering under what settings can I go into and add ,dun
[Sprint LG G4] andrewwm:
It's broken on Marshmallow sadly.
[Sprint LG G4] andrewwm:
It won't stay for long, once you do a profile update in settings it will reset the APN's and you'll lose it.

Also from time to time, your phone will do a profile update on its own and will also reset the APN's.

On MM, you can't access the IOT Hidden Menu anymore because now it requires root access.
[Sprint LG G4] williamvito:
Dumb question, but wouldn't we be able to access the IOT menu on Marshmallow if we knew our individual MSL and went into the ##3282# (##DATA#) menu?
[Sprint LG G4] daddymikey1975:
Without your MSL you can view all the options and I didn't see it in there to be able to change it even with an MSL.
[Sprint LG G4] centran:
So it is confirmed if you do the MM update and after a profile update you lose the free wifi hotspot? damn that sucks.
[Sprint LG G4] Agimax:
You can get your MSL code from here. Sprint wouldn't give it to me, so i thought i would share. Easy as pie. Works on Marshmallow 6.0. Just follow the same instructions.

[Sprint LG G4] ervman1:
This is what's keeping me from updating to 6.0. Are you saying the wifi hotspot mod is indeed working with 6.0??

Edit: My excitement clouded my reading comprehension. You're referring to being able to get MSL on MM :/
[Sprint LG G4] andrewwm:
I tried it but couldn't get it to work. The programs gives me an error when opening it and doesn't find my phone (Windows 10). I tried Windows XP and this time there was no error code but it couldn't find my phone. What did do?
[Sprint LG G4] Agimax:
Make sure you can use ADB first, if not you need to install proper drivers. The program ran fine, and as it states you need to use the program dropdown to change to the proper device port. I just followed the instructions and it read my SPC (MSL) just fine
[Sprint LG G4] KingFatty:
Has anyone been able to successfully enable wifi hotspot using the MSL, after upgrading to marshmallow? I can't tell if the MSL will even be useful for getting the hotspot?
[Sprint LG G4] shadow775:
I tried the Hotspot hack, with my g4 fw zv6 sprint still see my data usage? I thought the hack was for free Hotspot! I used 90% of my data is there anyway sprint won't see the usage?
[Sprint LG G4] david279:
Nope...
[Sprint LG G4] mswlogo:
If you have a data limited plan I believe you should get HotSpot. Most Sprint Plans are unlimited but do not include HotSpot. The Hacks are to get HotSpot running on an unlimited plan without adding it to your plan. But it will be listed as Data usage no matter what plan you have no matter how that data is used (phone or tethered).
[Sprint LG G4] midmofan:
Fortunately , as I was suspecting this would happen soon, I checked here BEFORE intalling the MM update! The update is not worth the loss of this feature for me.
[Sprint LG G4] andrewwm:
I been trying to find a dialer code to get into the IOT Hidden Menu and into the APN settings.
[Sprint LG G4] andrewwm:
Good for you! At least someone out there looks at my warnings about the MM update before spamming the comments about why it isn't working.

Not mad or anything, was trying to be helpful at first, just annoying.
[Sprint LG G4] antonio824:
I discovered a possible workaround on the hotspot for Marshmallow. To verify if it would work if the profile got reset before I upgraded I did a profile reset. It did in fact remove Wi-Fi tether. So I went in and redid it to add hotspot and then I went ahead and accepted the update...still have Wi-Fi hotspot. But here's the kicker. I didn't swipe away the menu so it's still in my task manager window or whatever it's called. The code has been changed but the task is still there and can be used if still there.

Tldr; you must open the quick shortcut and proceed to the last steps and the keep that in your task manager.
[Sprint LG G4] pelon90005:
This is getting exciting ??
[Sprint LG G4] carrilloevo:
What code did you use to access the apn settings?
[Sprint LG G4] antonio824:
I don't know the code. I took the steps to enable Wi-Fi tethering before I ever upgraded. I then make sure that I didn't exit out of the APN settings. I upgraded and then looked at my history or tabs button or whatever it's called and it was still there. I was then able to edit it from there and I have it still there in case my profile gets updated. As long as my history does not get deleted or swiped away it should remain there. That is my hope anyway. It is just a workaround for now but it must be done before upgrading to marshmallow.
[Sprint LG G4] fredwinky:
YES!!!

Just did this and i can confirm that it works!!! WIFI HOTSPOT WITH MM!!!!!!
[Sprint LG G4] andrewwm:
Yeah, makes sense why that works. Wouldn't rely on it.
[Sprint LG G4] antonio824:
Would there be a wa

---------- Post added at 08:01 PM ---------- Previous post was at 08:00 PM ----------

Anyone know of a way to extract the code to access this if I have access? And it's not reliable but at least a temporary work around.
[Sprint LG G4] andrewwm:
I am trying alot. Spamming the crap out of my phone with dialer codes. Can't find a good one. I did get my MSL but haven't thought of a way to access the APN menu with it (or any hidden menu). However I can now change values in the ##DATA# menu. There is a APN setting in there but I don't really know what I can change to get hotspot going.
[Sprint LG G4] Bombillazo:
Doesnt the upgrade to MM (ZV9) restart your cellphone though?
[Sprint LG G4] daddymikey1975:
It dies but running tasks remain after a reboot.
[Sprint LG G4] pelon90005:
Is there any way to get a logcat to find the file source that's opening up the apn settings in the task manager?
[Sprint LG G4] Bombillazo:
I did the trick but tether doesnt work. Tried connecting a console and it failed. Than my phone internet went crazy and barely have a connection myself.

5689#*991* hidden menu code let me know if that helps
[Sprint LG G4] Bombillazo:
Doesn't work for me
[Sprint LG G4] Bombillazo:
Antonio you genius! Here's what i did:

1) On ZV6, used the steps to get to ITO menu to change APN settings.

2) Selected LTE settings > APN settings. Open the App close button (square one on the bottom menu) and check that you have separate instances for the ITO and APN menu. THIS IS CRITICAL DO NO CLEAR THEM OR CLEAR ALL!

3) Applied the MM update (ZV9).

4) Let the upgrade finish and reboot.

5) When finished press the square button again and go to the APN settings window. You should be able to select the n.ispsn APN again and add dun to APN type. (NOTE: ITO will close if you select it but it doesn't matter. The important one is the APN settings window).

6) Congrats! You have Wifi tethering with MM!

7) Just in case you wanna test like I did, don't close the APN settings window and try to update system stuff to see if it changes the APN settings. I can confirm that updating your profile on the System Updates menu will undo the APN type change.
[Sprint LG G4] antonio824:
Yup thats exactly it! Great job of getting all the settings out there in nice organized steps. I typed mine up on my phone so it wasn't as easy! I hope this leads to a more permanent action since you could easily accidentally hit clear all tasks! But, it's a stop gap until then! At least we know the menus and everything are the same. Just about getting to them!
[Sprint LG G4] tabp0le:
Fortunately Marshmallow has app pinning, so you can pin ones to never clear with clear all.
[Sprint LG G4] Bombillazo:
Perfect! Thanks for the tip.
[Sprint LG G4] daddymikey1975:
So if we save it in the tasks, upgrade to 6.0, then pin it, we can get back to it after a profile update to "fix it" ?
[Sprint LG G4] tabp0le:
Yep! I just downgraded from MM, opened IOT Hidden Menu>APN editor, upgraded back to MM and pinned it.
[Sprint LG G4] daddymikey1975:
You should try a profile update so that the hack goes away (and verify it), then open your task and fix it again just to verify.

(this is awesome news) !
[Sprint LG G4] Bombillazo:
I already did. With pinned APN I can access it anytime to change it.
[Sprint LG G4] tabp0le:
Yeah, it's working.
[Sprint LG G4] daddymikey1975:
Gonna down grade tonight then. Awesome find gents!
[Sprint LG G4] andrewwm:
Wow, I am supprised people are willing to downgrade and lose their stuff for free tethering. Hopefully soon I can figure out a way in MM
[Sprint LG G4] tabp0le:
Just use LG Backup. It backs everything up.
[Sprint LG G4] antonio824:
YOU ARE A LIFE SAVER! I saw your email at work and then pinned it. Two hours later I hit clear on accident and it was the only thing left!
[Sprint LG G4] Bombillazo:
Now i really have no big reason to root. I just wanted wifi tethering. Now I have that PLUS Marshmallow. This is great! Totally worth downgrading and upgrading again.
[Sprint LG G4] fredwinky:
been running this for 3 days now without a flaw.
[Sprint LG G4] asamu694:
No hotspot option

I tried this method on my rooted flex2 but did not work. I dont see a tethering option. See attached pictures.
[Sprint LG G4] pelon90005:
Try the tethering settings menu not the share and connect
[Sprint LG G4] gLam16:
Hello guys i have LS991 zv9.

But can't able to avtivate Mobile network.

Already unlock.

Anyway to get Mobile network / Data connection ?

Already unlocked.
[Sprint LG G4] tabp0le:
You probably have to do a profile update to get data working. Then you will have to change the apn settings again to get tethering to work.
[Sprint LG G4] asamu694:
There is no tethering settings menu.
[Sprint LG G4] wanmap:
i have same proble like u ,i can edit apn to use mobile data.
[Sprint LG G4] Bombillazo:
Like it's been established, you cannot access APN settings normally. You need to the ZV6 trick and upgrade to ZV9 without closing the APN window.
[Sprint LG G4] wanmap:
i'm using 6.0 ,it's have another solution to fix it ?can u help me,sry my english was bad
[Sprint LG G4] Agimax:
As of now there is no other solution for MM6.0,you must downgrade to Lollipop ZV6 then do the screen pinning trick for the APN editor, then upgrade to MM. This metjod works and is relatively easy. You can use the LG backup program before downgrading to keep all of your settings and files.
[Sprint LG G4] daddymikey1975:
By using ##DEBUG we can look to see if "dun" is still listed in APN settings under Internet. (I found it this morning)...

Anyone know a dialer code to edit items in the debug menu?
[Sprint LG G4] smashclash:
So I downgraded to ZV6. My phone that did an auto reboot but got hung up at the Sprint Spark loading screen. I then pulled the battery and did a factory reset. It then booted up and confirmed I now have ZV6.

I then went back and downloaded quick shortcut maker and followed these instructions: [youtube tutorial to add wifi hotspot in hidden menu using quick shortcut maker] Problem is, when I get to the APN settings now my only options are cinet.spcs and ota. Internet is not an option. Is this normal after a downgrade? Do I try re-downgrading to ZV6 again?
[Sprint LG G4] smashclash:
I tried re-downgrading to ZV6 but same results. When I go into APN settings I can only see cinet.spcs and ota. I assume I should have been able to see internet since that's where you need to go into and add the ,dun.

What do I do from here?
[Sprint LG G4] Bombillazo:
Update PRL and profiles
[Sprint LG G4] smashclash:
Thanks that worked. To upgrade to MM do I try applying the OTA update or do I need to flash ZV9? (After leaving the APN settings open)? I'm trying to accept the OTA update but it just counts down the 10 seconds to apply, says it's going to reboot, but then does not reboot. Just hangs there.
[Sprint LG G4] Bombillazo:
I did the OTA update. Try rebooting your phone, check you have APN settings opened, then try to update.
[Sprint LG G4] smashclash:
Hmmm, restarted but no dice. Now the MM update isn't even there. I went to Settings>General>System Updates>Update firmware. It runs to check but then says "No firmware update available." This is strange. Not sure where to go from here. Thoughts?

When you say leave APN settings opened. I just need to make sure one of the windows for APN settings is still in the window list, right? i.e. Click the square and one of the windows is APN settings, correct? I could the click back to the home screen, or be in messaging, or any other screen it doesn't matter. Just as long as APN settings is one of those windows in the list once I go to apply MM.
[Sprint LG G4] smashclash:
Went ahead and flashed ZV9. Downloaded this: http://xdaforums.com/sprint-g4/development/restore-sprint-lg-ls991-zv9-tot-t3263790

Seems I have MM now and tether. In fact, I didn't even need to re-add the ,dun. It carried over from Lollipop. Maybe because I haven't done a profile or PPL update? I guess I should do that? I pinned the APN setting in the window list.
[Sprint LG G4] Bombillazo:
Yep, the dun addition wont be gone unless you update the profile, in which case pinning the apn settings will let you re-add it
[Sprint LG G4] smashclash:
Did a profile and PPL update. It did indeed remove wifi but went back to tasks and easily added it. This is awesome. Thanks everyone for the help.
[Sprint LG G4] xtreemgreen:
So this wont work if the phone came with ZV9 on it already?
[Sprint LG G4] Bombillazo:
You would have to flash ZV6
[Sprint LG G4] tabp0le:
It will work. Just downgrade first.
[Sprint LG G4] Bombillazo:
People, a new update has been released for the Sprint LG G4. This is version ZVA. Not sure if the trick still works if installing this update. If someone updates and has the pinned APN app, please confirm if it still works.
[Sprint LG G4] andrewwm:
I want to try it but haven't got a OTA yet. Does anyone have a .zip that they captured?
[Sprint LG G4] Bombillazo:
I took the risk and updated. So far nothings changed. Still have APN settings pinned.
[Sprint LG G4] Jawbox:
So, just a warning, because I freaked out when I did my update.

Immediately after update, if you hit recents, you may not see ANY windows. I had to open an app first, then all of a sudden, I had IOT and APN settings in my recents.
[Sprint LG G4] KingFatty:
And just to clarify, you will need to downgrade to ZV6 to pin the APN app right? Then upgrade back to ZV9 (because you can't run the app in ZV9), and then upgrade to ZVA?

I'm on ZV9 now, and my phone retained the free wifi hack because I haven't updated my PRL/profile yet, but I can't edit my APN settings that I know of without first downgrading to ZV6.

Just wanted to confirm what a hassle it is.
[Sprint LG G4] sn0rky:
i did this same thing. the wifi hotspot option is there, but when you enable it, it says "you are not subscribed to hotspot. do you want to see subscription options?" this goes to the self service menu that says to contact customer service to add hotspot.

does this no longer work on ZVA?
[Sprint LG G4] andrewwm:
It doesn't work at all on ZVA and ZV9. Only ZV6 and below. If you want tethering on MM, you need to downgrade. Look at the main post, there are directions.
[Sprint LG G4] Bombillazo:
It totally works on both. I have ZVA right now with the pinned APN menu. I can tether just fine.
[Sprint LG G4] andrewwm:
Yeah, like I said, look at the main post. I know you can do that. You need to downgrade first.
[Sprint LG G4] Bombillazo:
Ok. I thought you meant tethering stopped working if you upgraded.

Yeah, to those asking if the trick can be done if you are already at ZV9 or above: NO. You need to go back down to ZV6 as andrewwm said.
[Sprint LG G4] sn0rky:
thats odd. i had it working on zv9, then upgraded to zva and thats when it gave me the message to subscribe. i guess i'll try to downgrade and upgrade.
[Sprint LG G4] tech_0912:
Are you saying ZVA fixed the APN settings menu in the described hack to where you can't add dun to APN type?
[Sprint LG G4] pelon90005:
This is true. The only way to make it work for zv9 and zva is to open the apn settings in zv6 then upgrade to zv9, then pin the apn settings on your task manager(recent apps window). If your profile is updated then you open the pinned window and add the ,dun. It's also confirmed the pinning of the apn settings also work on zva.
[Sprint LG G4] huzordaddy:
I just went through two rounds of system updates, to ZV9 and then ZVA. I followed the instructions above to pin the app. Everything appears to have gone smoothly, and I can still run the Wireless Hotspot.

Many many thanks to the original person who figured out the APN hack and to those who figured out how to keep the Hotspot through the Marshmallow updates! :)
[Sprint LG G4] goumba:
Sorry, wrong thread.
[Sprint LG G4] KingFatty:
Can anyone verify what happens if you successfully get the pinned item working in ZVA, but then perform a factory reset in firmware version ZVA, what you need to do to get the wifi tethering workaround to re-appear?

I'm just wondering if you would then need to downgrade to ZV6 and repeat the entire procedure. Or is there any way to preserve the quickshortcut pinned item in ZVA after you perform a factory reset in ZVA?
[Sprint LG G4] carrilloevo:
Man I had the apn settings pinned and they freaking disappeared ????. So only way to get them back is reverting to zv6?
[Sprint LG G4] KingFatty:
You have me paranoid, so now in ZVA I will periodically look for the pinned app, and just click on it to bring it to the foreground and verify it's still running before minimizing it.
[Sprint LG G4] robchow:
Thanks for all the information; great stuff here.

I am still on LP and I haven't gone through the steps yet to enable the tethering but have a question that I hope you can answer: once APN window is pinned on MM, do you still need quickshortcutmaker app? Looking at the video, it would appear that the shortcutmaker app opens a system window (i.e., IOT hidden menu and APN) and thus, the app is no longer needed. I am looking for confirmation. Thanks.
[Sprint LG G4] sn0rky:
i kept it installed. it was pinned.

---------- Post added at 02:11 AM ---------- Previous post was at 02:10 AM ----------

anybody get the android system update? does this affect tethering?
[Sprint LG G4] KingFatty:
I haven't, but someone said that installing the ZVB update will similarly preserve the pinned APN window, just make sure it's pinned before you accept the upgrade. I still haven't. If you totally mess up, there is still another option, where you can put that mellow thing on your phone using a trick to pull the cord at 9% update or something, but if your timing is off your phone will permanently brick. So risky, and I haven't seen a video showing how you do the timing to get it just right, so I'm too scared to risk it yet.
[Sprint LG G4] WaterStarters:
There is zero chance of being able to get my phone from ZVB to ZV6 now right? Will there be a solution in the future or could I use the root ZVB and find a solution that way? Unlimited plan is useless now and I may as well switch to verizon. My phone is unrooted currently.
[Sprint LG G4] KingFatty:
Just install the ZVB ROM, it's mellowmallow or something like that, over ZVB. That ROM will include the APN window to make the edits you need to unlock wireless tether. There is still hope, don't worry. sorry if I messed up the name, but look around for the android development ZVB mod.
[Sprint LG G4] robchow:
Again, thanks for the steps; I got it to work.

In regards to the above about keeping shortcumaker app: I didn't need to keep it after the initial access to the APN window. I pinned the APN window and all is good.
[Sprint LG G4] thrasher324:
So I looked at my g4 and says that I'm on LS991 ZVB.

Can I still downgrade to lollipop (ZV6) and do this method?

My understanding is that it goes ZV6>ZV9>ZVA correct? Does ZVB come after the ZVA? So this would mean I'm on the latest firmware, and the only way to downgrade back to ZV6 lollipop is to flash correct?

So I would update firmware 2 times to get back up to ZVA or 3 times to get to ZVB? (If ZVB comes after ZVA.)
[Sprint LG G4] KingFatty:
I don't think you can downgrade from ZVB. I think you are stuck on ZVB only. But you could still enable the wifi hack if you install the mellow mallow ROM, or whatever it's called. Look for it in another thread. The installation is tricky because you have to pull out the cord at 9% progress or the phone will be bricked. If you do it, please take a video of the installation to share so we can see when to pull the cord out during the installation.
[Sprint LG G4] thrasher324:
Can anyone confirm that I cant downgrade if I'm already on ZVB? Im just getting into this whole android ordeal and very very new to the terms . Appreciate you all in advance, seems like a friendly community here

P.S. I thought flashing is the method used to change into different versions of ROMS? How would I not be able to flash back even if I'm on this "ZVB" newest version of firmware?
[Sprint LG G4] andrewwm:
I believe there is an anti roll back on ZVB so you can't if are on it already.
