Looking for some US variant modem unlocking, there has been mild success in getting AWS on GSM, etc by flashing NVRAM, qcn backups. I'm requesting a full dump (minus rom, modem, other flashables), the .txt dump from NV-items reader_writer v1.0 and QCN files.
How to provide your NVRAM dump:
1) Download NV reader/writer HERE and install THESE drivers (normal Samsung USB drivers).
2) Dial *#7284# and select "Qualcomm USB Settings" then check "RMNET + DM + MODEM".
*If you are running a aosp rom (cm9,cm10,aokp etc) you can use the diag method described HERE
3) Create backup.
a) Click "port" in the top left and select your samsung serial port.
b) Make sure BOTH boxes in the top bar are checked.
c) Click "Connect" in the top bar.
d) Click "Read" in the top bar.
e) Click "Read" in the lower 'NV-items' section.
f) Save the .txt file, this is your backup
*The process will take 5-10min. The file size will be roughly 3mb and "inactive item" and "bad parameter" sections are normal.
*To restore click "Write" in the lower 'NV-items' section and navigate to your backup file.
4) Dial *#7284# and select "Qualcomm USB Settings" then check "MTP + ADB".

I now see GSM networks on my GN2 and I'm prompted to insert a sim card. I'm showing success and need a nv-items dump with the method described above!
Thanks.

On my i717 I get 2 options
UART:
1. Modem
2. PDA
USB:
1. Modem
2. PDA
There is no 'Qualcomm USB settings' option for me to select.
How to fix "ERROR 16 - Switch ???" on gs3 flashed to boost mobile.
This is what I did. Hope it works for you
Might work in other cases.
Take battery out of flashed phone.
Connect Donor Phone
test donor phone and see if you can connect (make a test call, try to get onlne)
if not <contact boost mobile>
if it does, then connect it to pc and get PRL form it.
Load QPST, under Start Clients menu, select Service Programming.
Click Read from Phone and enter MSL (000000).
Then Save to file. This will save a .qcn and .rl0 file.
In QPST, under Start Clients menu, select RL Editor.
In RL Editor, load your .rl0 file. Go to File, Save As..., make sure type is *.prl and enter a file name. Save file.
Turn off Donor and remove battery
Connect Flashed Phone
What You Will Need
The DFS CDMA Tool
Your MSL number (Sprint) or SPC number (Verizon, this is usually "oooooo").
Obtaining your MSL/SPC number is as easy as calling up your carrier and asking for it. They will freely give it to you. Other options include using the MSL Finder app. If that does not work, you are probably on Jelly Bean, so you will need to make a quick call to your carrier.
Step 1: Enable Use of DFS CDMA Tool
The use of this tool requires a non-standard USB connection (i.e. Download Mode, or just DM).
Open the Dialer and type in ##DIAG# (##3424#).
Click on "Qualcomm USB Settings" and select "DM + Modem + ADB" then press "OK".
Plug your device into your PC and go to Device Manager.
Locate "SAMSUNG Mobile USB Serial Port" and remember the COM number (in this case, COM5).
Step 2: Load Device into DFS CDMA Tool
Open DFS CDMA Tool. If you are using the Demo version, there will be a small countdown and the app will launch.
In the upper left-hand corner, hit the "Ports" button and select the port you found in Device Manger.
Double-click the port, and double-click it on the bottom to load your device into the software.
Enter your MSL/SPC number where it says "SPC" and hit the blue arrow. You should see the log show "Device Unlocked".
Step 3: Write New PRL
Hit the programming tab, then the NAM sub tab.
On the right-side, load the PRL that you want, then hit "Write".
Disconnect your device, go back to Step 1 and put your device back to "MTP + ADB". Back out of the menu and reboot your device.
Confirming PRL Change
Go to Settings -> About Device -> Status. Scroll down to "PRL" and confirm that it has been changed.
Take battery out of flashed phone. Again
go to "boostmobile" and login/create your account.
goto update handset
enter info for another boost phone (not donor, not flashed phone)
turn on 2nd boost mobile phone
go through the steps and test it for connection (calls, internet)
turn off and take out battery.
goto update handset again
enter info for Donor Phone (not 2nd Boost phone, or Flashed Phone)
turn on Flashed phone
go through steps, reboot
nJoy.......
When i put on the chip, the IMEI set to NULL
I've already tried many ways to fix this, but no success...
Please, someone help me!
I don't want to lost my optimus G!
thanks
You should restore your imei with your EFS backup...have you unlock with freegee or you are completely stock and have never touched nothing?

Hi, if you get the error in step 13 test select Setting option> comport> and select the port to which you are connected again and give OK. Good luck
Hey guys, I will reactivate this topic a little. I ve got LG F180K and I converted it to E975 without doing EFS backup (still had imei number but no signal). I flashed modem for K and it still didnt work, flashed L modem and it...worked. No LTE and no 2G, only 3G, still imei.
What to do then if I want come back to F180K ROM? (NO EFS BACKUP)
If you unlocked using freegee the imei backup folder is their in your internal storage root folder. freegee backups even if you don't choose to.

Do this step for no signal if your IMEI is correct(not null).Root is necessary for this step
Install "SQLite editer" from Google play to open "settings.db" in location "Data\data\com.android.providers.settings\database s" select "global" -> find "subscription_mode" change value "1" to "0" then save and exit.

EDIT: Already got help from someone here. Thanks! "Case is closed now".
Hello everyone,
unfortunately I bricked my Find 7a while trying to expand the 3GB internal storage with Chinese partition layout. And I don't know where it went wrong. :crying:
I already tried the Unbrick tool (Sahara) and restoring the old partition layout several times. And the partition layout recovery worked, but ColorOS says my NV partition is still invalid. It seems this partition got damaged and now my IMEI is gone and I can't use my mobile network anymore.
And sadly I figured out that the normal TWRP doesn't even show the NV/EFS partition to back (only modified TWRP do), so I don't have an backup of those partitions.
One last change would be to take an backup of another phone, anonymizing it by overwriting the IMEI and kindly sending me the copy.
If someone is willing to do so, I'd be very happy so I can reanimate my Find 7 .
I attached a tutorial:
1. Needed software:
Qualcomm QPST Diag drivers
Qualcomm QPST Tool
IMEI converter
Any hex editor, e.g. HxD Editor
2. Start phone in Diag Mode:
-Enable Developer Settings and then "USB-Debugging" on your device
Install the drivers. They are already signed, so no need to disable Windows signature check.
To enable the Diag Port, either under
a) ColorOS:
-Call *#801# and enable "Engineer Mode Toggle"
b) ADB and root access:
ADB commands:
-adb shell (only when accessing the phone with ADB from pc, not necessary when using TWRP adb terminal)
-su
-setprop sys.usb.config diag,adb
Now in the in the device manager you should see a "Qualcomm/Oppo HS-USB MSM Diagnostics 276C (COM y)" device
3. Backup the IMEI/Baseband infos:
Again, we have 2 alternative ways:
a) QFIL
Open QFIL: C:\Program Files (x86)\Qualcomm\QPST\bin\QFIL.exe.
Did QFIL already automatically recognize the Diag Port in the first row?
From the top menu "Tools" choose the entry "QNC Backup Restore". Backup the QNC
b) QPST
Open QPST Configuration: C:\Program Files (x86)\Qualcomm\QPST\bin\QPSTConfig.exe.
Under the tab "Ports" there should be the COM port from the device manager above.
If not, try "Add New Port" and untick “Show Serial and USB/QC Diagnostic ports only” and choose the right COM port and click OK.
If this doesn't help and no device shows up, add the COM-Port manually by typing the following:
Port: COMy (replace x with the number of what the device manager is showing you for the "Qualcomm/Oppo HS-USB MSM Diagnostics 276C (COM y)"
Label: You are free to name this port what you want
Then in QPST Configuation open the top menu entry "Start Clients" and then "Software Download". Select the port of the device in diagnostic mode and press OK.
Choose the “Backup” option tab, click browse, choose your destination and name of your QCN backup, choose the "QPST NV Memory Files (.qcn)" as “Save as type”, NOT the first option as (.xqcn).
Click “Start” and wait for it to finish. This will back up all your phones NV Items and save them to the QCN Backup File.
5. Anonymizing your IMEI:
Open the .qcn file with HEX editor.
Search for your IMEI in HEX format. To do so, use the IMEI converter, enter your IMEI.
[For your own verifcation: An IMEI in HEX always starts with "08" followed by your first IMEI number and an "A". So if you have IMEI 123456789012345 the HEX format would be 08 1A 32 54 76 98 10 32 54.]
Now search for the converted HEX string (or better search for the first four characters 08xA only). Keep in mind to set the search type to "HEX values" not "Text" or anything else.
Replace all numbers after “08” with dummy numbers, so the result will e.g. be: 08 1A 22 33 44 55 66 77 88. Please copy your chosen dummy HEX IMEI, so I know what I am searching for to insert my IMEI then.
Save the file (as another copy, don't replace your original file in ase you will need it some day)
6. Share the anonymized file with me over PN
I thank all of you for your help! :victory:
Hello, I am new here and I would like to know if it is possible that you could share the file that happened to you since I have the same problem after partitioning my cell phone Beforehand thank you very much Sorry for my bad English
hi. had same problem with imei missing in my phone after hard bricking it and partition all mess up but now I done reparing the partition, some error come up says nv partition error. then I find out the imei is missing. please send me the dummy imei to my email. hope I can have my phone back.
