Thank you to m4f1050 for pointing me in the right direction!
This is used to change the PPP user ID so that you can switch to another CDMA provider and use their data plans. Normally if you try to change the User ID to (ESN)@new.carrier.com, the phone will revert back to (ESN)@mdata.vmobl.com upon reboot. If you follow these directions, the settings should stick. This was created for the Optimus V but it will most likely work for other phone with the same issue.
Warning: Do not do this unless you understand the consequences. You will lose access to your VM data plan by doing this. You will need to change your User ID back if you want to use VM again.
Download QXDM and QPST.
Install both QPST and QXDM.
Follow the steps found here to get your MSL code and to configure QPST. You can stop at step 8 of "Update your PRL". As a last resort, if the previous method fails, you can get your MSL code by following this.
Download these rar'ed text files: Qualcomm.rar
Unrar them and place them inside C:\Users\Public\Documents\Qualcomm\QXDM\Vendor\Qualcomm\
Overwriting the original files. If they fail to overwrite the files, right click Diag.txt, select properties and uncheck "read only". Do the same for NVItem,txt.
Open QXDM Professional
If your phone isn't already recognized and connected, Go to Options > Communications and select the appropriate Target Port. This will be the port you configured in step 2.
Once connected, under view, select NV Browser.
Scroll all the way down to item 39939 and select it. The lower half of the window should show a list of values.
Hit read. Take note of the values in case you want to reverse what we are doing, and then turn them all to zero under "input". You edit them by double clicking them
Hit Write.
Next, without touching anything else, open QPST Service Programming.
Select Read, enter your MSL from step 2. An error will pop up, but ignore it.
Edit M.IP and PPP Config - AN entries to your desire.
Hit Write and Enjoy!
After you do this once, you can change your User ID by starting with step 12. You do not need QXDM any more.
doesn't seem to work for me. 39939 is empty

I plan to use a regular Evdo dumb-phone (not an Android) as a donor. Is it even possible?
got it to change but still no internet on VM. I am converting sprint Optmimus s to virgin mobile .. but I haven't been able to get data to work. I am now able to change the MIP settings but the first profile always gets enable and the 3 disable. I can change the 1profile to anything now with tutorial, just not able to disable it.

Does anyone know the code to disable LDB on an LG G5?
I can find the codes for the G3 and G4, but not the G5.
Any help would be greatly appreciated.
Download and install the Hiddenmenu APK in the first post here:
https://forum.xda-developers.com/sprint-lg-g5/how-to/guide-gsm-unlock-sprint-lg-g5-t3574819
Open the app > "SVC Menu" > "LDB" > "LDB Setting" uncheck "Enable, MLT will run after booting"
Maybe this will work on your phone too:
see here: -> http://devtester.ro/projects/lg-firmwares/mlt.php
WORKS WITHOUT ANY APP!
short info:
dail *#546368#*850# to enter hidden menu
( XXX must be the number of your phone!! )
tap on SVC menu as next
tap on LDB menu
uncheck LDB "enable"
reboot
:fingers-crossed: hope this will work for you!

Dialer codes don't work for 100% of phones, but yes OP should try that first. If dialer code doesn't work, that app may work instead; confirmed working at least for stock Nougat Sprint G5.
(I have an LS992 Sprint G5 on stock Nougat but it's running a GSM SIM with the APK SIM Unlock method linked in previous post. Dialer code only gives me an error with this configuration.)
i learn more & more at every day!
(btw: see 2.) of my signature)
before i asked many people for fix but no correct solution is got but ( thanks for devs support). now i experimented and solved imei and efs partition currupted by qcn method
NOTE: ( third party qualcomm imei changing softwares will not work i tried many but no use)
steps
1. first download tools and install
2. go to qpst.exe in c:/programfiles/qualcomm/bin/qpst
3. now connect your phone open port by dialing(*#*#76937#*#) in stock
4. check whether qualcomm diagnostic port is enabled or not in device manager
5. if it shown enabled and device info its connected through diag port in qpst
6. now click software download and take backup of ur partition and save as (.qcn) and click on start it will read ur partition and
xx.qcn file will created(xx is any name)
7. now open hex editor search your imei number with [08xa] x is your starting digit of imei example(087a) for second imei click
find next option
8. now open your imei convertor and palce your imei and click convert
9. replace that converted imei in the form of hexadcimal replace with old imei same for second imei
10. important thing is while saving the file only by (save as) which is important if any mistake is happen we cant recover after
restoring in efs partition.
11. after saving again go to qpst npw go to restore option now click on start .
thats it! you got imei and signal:laugh::laugh::laugh:
i struggled 3 days for this to find correct way recover my ime
tools here
I would suggest to install Xposed and you can find IMEI changer in the download section. This will change only one IMEI number though. I mean IMEI1=IMEI2.
Another option is to use DFS tools.
And a 3rd option is to use Xiaomi (or similar for dual SIM) IMEI changer, you can use it to change both IMEI numbers.
All can be done provided that you have the box that the phone was packed in with the IMEI numbers on it.

Go to the section Guides where you have posted in a topic with "unlock bands..." There you have all what you need in the OP. Connect your phone in DFS tool, check the section where you have IMEI and update it.
Or use what I wrote with Xposed and IMEI changer.
PLEASE DO NOT CREATE ANY MORE THREADS!!!

sir i downloaded i triedwrite imei but its only sim 1 imei apearing
sim2 showing unknown
Search for "WriteDualIMEI(W+G_eMMC).exe" file. Once you found it, check instructions on google to change the IMEI. It is working for Xiaomi devices as far as I remember. I tried on LeMax2 and it worked. I said I'll do a guide but time did not allow and also I forgot later on. For sure you can find instructions on xda as well.
This is the only tool I found to change both IMEIs.
Good luck!

I'll write down the instructions for you.
1. Phone should be rooted, adb drivers installed
2. Connect the phone to PC and select MTP and USB debugging
3. Open command prompt from Start. In Run, type cmd.exe
4. Type in the command prompt the following: adb shell
5. Then it should show [email protected]_x2:
6. Then type: su
7. Grant access on the phone
8. Then it should show [email protected]_x2:/ #
9. Type: setprop sys.usb.config diag,adb
10. The phone will go to Diag mode, check in device manager if it's like this. It should show at section Ports: Qualcomm HS-USB Android DIAG 901D (COM6). "6" is an example.
11. Open the WriteDualIMEI app and you should see in COM: COM6. This means that device is connected and you can type in the IMEIs.
12. Press START and that's it.
I want to open menu 'Testing'. I tried code *#*#6130#*#* and *#*#4636#*#* (*#*#INFO#*#*) in the dialer but they not work on my phone. I mean the window in which can choose 'Only LTE' mode. This window looks like image from attachment.
