Sprint G flex 2(LS996) GSM (DOMESTIC) Unlock [Guide]

I'm not responsible if this damages your phone, attempt at your own risk.
Hi everyone, I have stumbled upon what appears to be a working unlock solution for the G flex 2 (LS996). This is essentially a similar method of unlocking the g3, but with my unlocked by sprint node.db files. Currently MMS and Calling are not working for me on ATT, but data (LTE) and texting works. I beleive I know why calling is not working, as well as MMS, but I am not sure how to fix it, I am new to unlocking using root. Anyways, on to the guide.
First you will need to root your G Flex 2
You will also need Root Browser
Now after you have rooted download the files attached to this post
Next transfer the files to your phone if you did not download on your flex2
*Back up your node.db and node.db-library by adding .bak to the end in /carrier/apps
Once the files you downloaded are on your phone extract them to /carrier/apps
Now restart your phone with your non sprint sim card, or sprint if you are unlocking for future use
When the phone boots you should see that it is recognized, but the carrier still identifies as sprint
Go into settings, more, set mode to global, then go to apn settings and add in your apn
Now you should have full sms and data
This is as far as I have got at the moment, but I am working on calling and mms on at&t, it did appear to be working on Verizon though
Now to where I need some help:
First is calling. I think I have identified the 2 things that may be causing the problems. First is call barring, when I opened up a hidden phone menu it said that incoming, outgoing, etc calls were locked. When I try to enter that submenu to unlock them it says something about the sim or crashes. Next is hd calling. When I dial a number there is a hd symbol next to dialing, I don't know what that is, but if it is sending the call over data I am assuming that there is some type of problem with it sending it to a sprint server or something. If someone can help me figure this out I will be very thankful.
My next problem is MMS, on at&T. Whenever I try to send or download one it does not work. I might just have messed up my apn a few times but I doubt it. The MMS settings in hidden menus show up with sprint settings, and I have tried changing them but they just revert. Could anyone help me out?
PS Sorry about adding two files the first one did not show up when I posted and now I don't know how to remove

I am getting hands free activation now and then please help.Tried everything below.

Try this..
with root explorer : Go to system/app or /system/priv-app folder.
Locate Sprintsyncml. Apk
Rename it to Sprintsyncml. Bak
or
Search for OmaDmclient.apk, then click and hold the file till it popups a secondary menu, in secondary menu select RENAME.
Rename OmaDmclient.apk to OmaDmclient.apk.bak and press ok.
or
LGstartupwizard.apk... Which is located at
/system/priv-app
try this options it should work..it will disable the prompt
Thanks only found LGstartupwizard.apk but it is still popping up after rename..Please help

Yes that's true. Take care about permissions setup, use root explorer for that purpose. In three countries I use this phone LTE works mostly in bands 4, I also enabled that band using a guide I found here.

I had the phone unlocked by sprint and can still not hook on to AT&T. What are you offering?

5.1.1 can unlock gsm sim too? Thank You

Changed my build.prof and got calling working flawless, just cant seem to be able to change apn settings.
ro.carrier=spr
ro.build.target_operator=spr
With this, you can also changed the spr to tmo if you want.
Anyone know how to make it so I can change apns?

When in the build.prof editor in Root Toolkit Lite, I simply changed it from "SPR" to "spr".
##data# isn't helping because I dont have the msl/spl. Everytime I go to change the APNs it wont allow me add one in. I can edit files if needed, I just need to be able to edit it haha

@carlosirai, others,
can you help me a bit, as your post intrigued me as follows :
i bought this phone - rooted and unlocked as per method above by ebay seller for international usage.
currently, the phone is technically domestic unlocked and rooted on ZV6. this results in no OTA and node files for SPRINT modified!
as an internationsl user, who will not be using US Domestic providers or Sprint, can i unroot on ZV6? then upgrade to ZV9 then root as/if required and use with an international provider? this usage will be on 3G & LTE ( Bands can be enabled as required, post root )?
thanks in advance!
any help you

I contacted sprint and they said that my imei is not activated in system

Try this:
Go into the phone dialer and type: 5689#*997#
Go to Field test > Modem Settings >RAT Selection > SELECT: GSM/WCDMA/LTE Auto
If it doesn't work, select LTE/WCDMA, then toggle back to GSM/WCDMA/LTE Auto
If it still doesn't work, remove the sim and try these steps above without the SIM, then retry.
Don't forget to update your APN settings for your carrier.
If that doesn't work apparently Em_Will_I_Am on Sprint's community site/forum has been able to assist, give him a pm
It's not difficult to root an updated ls997, it's flat out impossible and attempting anyway results in a brick.

[GUIDE] Activate VoWiFi / WLAN Call

First of all a BIG thanks to ed-gonzo
He made this possible
This is the instruction to activate VoWiFi / WLAN Call on the Poco F1
Its tested and verfied to work with EU ROM (Oreo , Pie and Q based) and german provider o2 (Telefonica)
Before you read on i want to make clear that I am not responsible for bricked devices !
Basic requirements are root rights to do this mod
Maybe latest 2020 Qualcomm Diag QD-Loader Windows 10 Drivers signed are needed for this to work.
!!! Before doing this Mod you should backup EFS-partition !!!
- download QPST tool and install
- enable USB debugging in Developer settings
- now either go to terminal app and type:
Code:
su
setprop sys.usb.config diag,serial_cdev,rmnet,adb
or
adb from PC
Code:
adb shell
su
setprop sys.usb.config diag,serial_cdev,rmnet,adb
- connect Poco F1 with original USB cable to PC
- start PDC (from QPST tool) on PC
- Poco F1 should be recognized by PDC (if not install Qualcomm driver and check Device Manager)
- activate corresponding profile (in case of german o2 its DT_Greece)
- install VoLTE & VoWiFi Enabler Magisk module (optional) or activate setting with dialer code *#*#869434#*#*
- restart Poco F1
- Voila

FAQ:
Q: What are the requirements for VoWiFi
A: A provider resp. plan which includes VoWiFi
Q: How to know if VoWiFi is working ?
A: Put phone in airplane mode and reactivate WiFi only. If you are able to make a call then VoWiFi is working.
Q: Does this only work with MIUI ROM ?
A: No ... its reported to work also on Custom ROMs like LOS, crDroid ...

Thx for this guide! Have been waiting for this.
Does this work with custom ROM (LOS)?
in case of german o2 its DT_Greece? are you sure? german carrier and greece?

Ok thx will give it a shot as soon as I get access to a windoze PC :highfive:

Ok this definately didn't work on my Poco-f1 with latest LOS16 and 8.11.15 vendor/fw. Funny thing that VoLTE now seems to be gone (Device switches back to H+/E). Got it back by restoring efs. Has anyone else been successful with this running custom ROMs? Even without this "hack" I have been able to activate VoWIFI after 8.11.5 update but it didn't work so I guess this depends on FW version.
Two things - a little offtopic though: Any Idea if this can be tried on the MiA1? I suspect that xiaomi doesn't include support in it's firmware for this device at all and I 'm afraid to cripple both my devices (Poco and MiA1) at the end .
Has anyone had success getting HDVoice with BT headsets on the Poco-f1 with custom ROMs? Sorry for asking this here but in the LOS thread I seem to get ignored with this question / bug report.

@saski4711
to bad that its not working for you.
It defintively works with EU ROMs based on Oreo or Pie.

Yeah bummer. Will give it another shot the next days maybe I messed up somewhere. Isn't this device supposed to get VoWIFI by default with the Pie update anyway? Maybe this will work OOTB with final pie?

not works with EU pie rom to me too. from Sri Lanka we have VOWIFI network. tried switching many profiles but not works .

Dont know ... i'm on Stable EU ROM 10.0.6.0 (based on Oreo)

I know for sure it worked out of the box after pie update on stock beta with a service provider in Greece.
Can make settings appear with *#"#vowifi#*#* but being in India don't think providers support vowifi so doesn't work.

2 diff statement.
Can enable with code but doesn't work in india.
It worked for a friend in Greece without doing anything immediately after pie update.
What I was suggesting that maybe and just maybe if provider supports it ,vowifi can be enabled simply by code.

It is working perfect. I did some test calls on wifi. Thumb up..... BTW I'm on German Telekom D1

could you please tell us which ROM you are using and which profile you activated within PDC ?

I'm using 8.11.27 global beta and I modified the DT_greece section. Set sub0 and sub1 to active.
Opened dialer and dialed *#*#vowifi#*#*

ok this works, just needed a bit more work for WoWiFi in my case
after a reboot it kept returning to my default carrier config (VoLTE working just fine anyway)
so what I did was to remove my carrier config from within PDC Tool, just that by doing that it defaulted to a non-VoLTE config
well, removed that also and this time it kept DT_Greece config on both subs
VoLTE works and VoWiFi also (carrier Orange Romania)
ps. don't restart phone if you want to test new configs
just click on activate and enter airplane mode then exit (keeps testing faster)

I've gotten as far as I can with my Mi Mix 2S, works on both AOSP and MIUI to allow the radios to be enabled, and the settings to appear in MIUI (AOSP usually shows them anyway).
With this said, I tried only enabling the WiFi option on the carrier that already had the sim activated...
I see many people here on different carriers in the EU who enabled the DT_Greece options and voila. Is this an accurate conclusion? I'm wondering if I just need an answer from a carrier other than my own to acknowledge the WiFi option exists to turn it on? Being in the US it seems as if the DT_Greece config could cause some problems, but it's not an option in my list. I don't know at this point.
Edit:
Tried all the US bands and even a few others, specifically ones that said WiFi. None worked so far, I'm going to cry! :crying::crying::crying:

I tried this on a Redmi Note 5 Pro but after selecting the device in PDC it throws an error message and doesn't show the list of carriers.
I've tried QPST 2.7.420 and 2.7.474 and a couple different pie roms, windows 7 and 10 but it always fails.
I can use EFS Explorer and dump the NV data just fine though...

VoLTE & Oneplus phones?

Hi there,
Cutting to the chase.
Australian, use Vodafone AU when at home, but working in the Philippines a lot this year (Smart Philippines), plus travel often to Taiwan.
Need VoLTE for VF AU, would love it for Taiwan (TW Mobile), dont think Smart offers it at all in PH YET, but if and when, would also be great, but less critical.
Currently have a Pixel 3 XL from VF AU, so thats sorted.
Wondering, if I get a Oneplus 7 P, what is likely to be needed to make it work?
Previously had to run custom ROMS on previous HTCs to get non native network support for VoLTE, even then it required the ROM cooker to code it in.
Please educate me!

there must be a way to enable serial and full-port switch (also the VOLTE switch similar to *#800#)
im pretty sure its a qualcomm / factory mode settings, it must have moved somewhere else.
i cant image oneplus getting rid of it all together.
whats TP debug?
ive sent an email to OP hopefully they can get back with an answer.
i know my pixel3xl enters a qualcom mode when i press the volume up button and have it plugged to my PC (from power off - hold down volume up and plug into PC)
maybe its similar?

you could wait for the MSM tool to be released
if you break something you can always use the MSM tool to repair EFS
pretty sure you can create a backup of efs using fastboot (i dont know exactly how)

I have VOLTE just popped sim card in and it showed up. Didn't have to do anything. 12gb unlocked version on ATT.

Qualcomm drivers don't seem to work with the 7. Can't find the device in PDC after enabling serial & full-port switch.
I noticed compared to the 6, that VoLTE and VoWiFi works for one of my carrier (Vodafone NL) out of the box. The trick that I did on my 6 also made VoLTE work for my other carrier (KPN NL) which doesn't work with the 7 pro out of the box.

Out of curiosity, what was your phone before? Mine is due for delivery today, I have ATT and my phone before is a 6T. Just wondering because I want to make sure I still have VoLTE. Thanks!

did you open as admin? i dont see why it wouldnt work
did you connect phone then open the PDC software?
perhaps we need an updated PDC/QPST tool?
Qualcomm drivers: https://qc2.androidfilehost.com/dl/...4074/QUD.WIN.1.1+Installer-10037.3+Setup.zip?
QPST: https://qpsttool.com/qpst-tool-v2-7-474
try these. they look like the latest versions.
perhaps try a different USB port also.
if this doesnt work, we might have to try and get in touch with the OP and see if they know of any way to get it working.
i dont have my 7Pro yet to try this.

I tried with 2 different computers and I have those exact versions you linked installed.
Yes, I opened as admin.
Yes, I connected the phone first then opened the software. I tried reconnecting with the software open too but also, no luck.
I tried searching for a driver in Device Manager manually by browsing to both the Qualcomm and OnePlus folders.

Hi PPLs,
Has anyone managed to force VoLTE Calling to be enabled on OOS12? I am using the OnePlus 8T and my wife uses the OnePlus 9. I have had to rollback both phone the OOS11 after testing OOS12 and realising the OnePlus Log Kit app no longer works, therefore no way to enable VoLTE calling.
For now we are holding on to OOS11 (with the Log Kit fix) until we find a fix in OOS12, otherwise we both might be forced to look and another brand of phone, which I really don't want to do.
Just as a side note, I was using a Realme XT which I bought in 2020 which had VoLTE enabled by default as soon as it recognised the SIM, so the network is capable, but I get no support from Vodafone AU as the OnePlus phones are imported as they are not generally sold in Australia. It seems the same story with all Australian carriers.
Also, my main reason for not rooting the phones is since we use them as daily drivers and need to use secure banking apps.
I know a few people have asked similar questions before, however I'm hoping there might be some progress on this soon.
Thank you!
Currently running: OnePlus 8T (KB2000) & 9 on OOS11 - Vodafone Australia

Has anyone managed to force VoLTE Calling to be enabled on OOS12? I am using the OnePlus 8T and my wife uses the OnePlus 9. I have had to rollback both phone the OOS11 after testing OOS12 and realising the OnePlus Log Kit app no longer works, therefore no way to enable VoLTE calling.
For now we are holding on to OOS11 (with the Log Kit fix) until we find a fix in OOS12, otherwise we both might be forced to look and another brand of phone, which I really don't want to do.
Just as a side note, I was using a Realme XT which I bought in 2020 which had VoLTE enabled by default as soon as it recognised the SIM, so the network is capable, but I get no support from Vodafone AU as the OnePlus phones are imported as they are not generally sold in Australia. It seems the same story with all Australian carriers.
Also, my main reason for not rooting the phones is since we use them as daily drivers and need to use secure banking apps.
I know a few people have asked similar questions before, however I'm hoping there might be some progress on this soon.
Thank you!
Currently running: OnePlus 8T (KB2000) & 9 on OOS11 - Vodafone Australia

Actually there is a way, but not straightforward and if you mess up, you can brick your phone.
First of all you need to unlock engineering menu in OOS12 and in MBN section try to enable VoLTE. If after this volte still doesn't work, enable diagnostic ports via engineering menu, and only after via QPST and PDC activate carrier profiles for your region (Vodafone Australia).
P.S: Making it via root is easier, as Volte is enabled via Magisk module, and diagnostic ports for PDC & QPST are enabled via basically two commands in adb.

Why not try LineageOS 19.1(Android 12)?
Volte works fine out of box.
You just need gapps, magisk and some module to pass safteynet check, then it's all good.

Thank you for the tip! I'm pretty comfortable with digging around like that.
I'll definitely give that one a go in the near future. It's my daily driver at the moment so I need to pick a time or use an old backup phone for a while.
Much appreciated!

Thanks! LineageOS is usually my goto, but in this case it's my daily and I need all the secure banking and similar apps to work.

Thank you!
Will give it a go on my wife's OP9 which I've kept on OOS11 because on this.
FYI I recently bought a OP10 Pro EU version and everything works perfectly including VoLTE & VoWIFI.
Looks like maybe the Global versions are having VoLTE issues in Australia on some carriers.
Only just bit the bullet 2 weeks ago with the OP8T and installed LineageOS 20. Works great out of the box.
I might consider re-flashing the stock OOS13 ROM on the 8T just to try this fix too.

UPDATE: GREAT NEWS! GOT VoLTE WORKING ON 4G & 5G - SOLVED
Thank you so much @ghost.ign !!
I finally got around to unbricking my almost forgotten OP8T KB2005 International Version using MSMDownloaderTool and tried the tweak using the link you provided. It worked!
Best part was, it worked on the current OOS13 and persists after reboot, as well as removing & reinserting the SIM. Very happy!
It's now time to update my wife's OP9 and do the same. Fingers crossed.
Many, many thanks!!!
FYI - For anyone else reading. I found the details to unbrick my OP8T here:

TIP: When installing the Qualcomm drivers on Windows, boot using the Windows start-up option no.7 to allow unsigned drivers. (Knowing that could've saved me a couple of hours.)

Hey any workaround to access pdc to change mbn profile on oos12 non root?
I have tried the shizuku and pixelims, but my ims status not registered.

Thanks for the response, i checked that thread already, for oos12, they need rooted phone.

I can confirm that Oneplus 8T (KB2003) on OOS13, using Shizuku and Pixel IMS can activate VOLTE. I am using KB2003_11_F.63 build.

I'm unable to confirm, maybe someone else can. I can however suggest that there's is likely no harm trying. I believe it should work across all carrier unlocked models.
Give it a go and report back if you can share.
FYI - since upgrading from OOS11 to OOS13 my model number has changing from KB2000 to KB2005 using the standard OTA upgrade process.

Recent updates have made this method a more dangerous option. I can't go back
If you know how to put it back together, I'd love to know.
