For about a year I have looked for a way to read and write NAM data from HTC CDMA phones.
Today I finished my search and have put together a kit for doing the above stuff, at least for the Apache/6700. It includes all the drivers and a very nice program to hack around with your phone (CDMA Workshop).
You guys have helped me out SO much in the past, so I'd like to give something back.
So without further ado, here are the instructions.
1. Remove all drivers from previous attempts to get it working (if any) then download the attachment and uncompress to an empty folder.
2. In ActiveSync, go File -> Connection Settings and uncheck the box labelled "Allow USB connections".
3. On your phone, go Start -> Programs -> File Explorer and browse to the Windows folder.
4. Scroll down until you find a program called DMrouter. Open it and click start.
5. Plug your Apache into cradle/cable.
6. The add new hardware wizard will come up. Do not allow it to connect to windows update. Click next and select "Install the drivers from a specific location" and browse to the drivers folder inside wherever you put the ESNkit.
7. If all goes well, another add new hardware wizard will come up. Repeat the exact same process as step 6.
8. On your computer, go Start -> Control Panel -> System -> Device Manager -> View -> Devices by Connection. Then play around until you see under a USB Root hub a USB composite device with two devices in its sub-tree. One of them will have a COM port number e.g. COM6. Write this down.
9. Go into the ESNkit folder and run cdma_wshop_loader. The password is ogmisthebest
10. CDMA workshop should load. Select port you wrote down e.g. COM6, click Connect, click Read, and you're in!
How to read SPC (Greetz to rafaelc, this is for you )
After step 10, go to the Security tab, and under the SPC section, select Universal, EFS Method in the listbox.
Click read.
Click OK in the dialog.
There will be a dialog pop up with a whole lot of dots and numbers. The first 6 Numbers after the dots end are your SPC.
If you want to change NAM data with this SPC, type it into the box and click SPC then click Send and go to the NAM tab, click read, and hack away!
How to change ESN (Proof of concept , changing to an actual ESN is illegal pretty much everywhere)
After step 10, go to the Security tab, and under the ESN section, select Universal, EFS Method in the listbox.
MAKE SURE YOU WRITE DOWN YOUR CURRENT ESN JUST IN CASE.
Click Read.
It will show your ESN!
To change, type in your new ESN and click write.
Done!
Have fun guys!!

Avast found it too!
There is no backdoor trojan, I suspect Avast may be picking up the loader for the program as a trojan. Avast is a hypochondriac program that sucks anyway
My NOD32 doesn't pick up anything.

Wowee...
I think it may be detecting the loader as a virus because of the way it fiddles with the RAM. Just a guess though. Note the _probably_ a variant. It does honestly work fine.
What just happened!!!
I did everything that you said, and it restarted my computer when i opened the program!
To change the esn... does that mean i can use a phone that is on the lost list then?

Program is probably buggy, does some stuff with memory pointers to make the CDMA workshop think its registered and may have thrown something out of balance. I give you my word that to the best of my knowledge your computer will not be broken in any way.

Hell yes it does.
ALSO, update:
I'm looking for a full version of CDMA workshop that doesn't throw everybody's antivirus programs into paranoid spasms, will post back later with results.
I tried it again and it worked this time, but i still have the drivers from last time, how do i uninstall them? thx
went into antivirus spasm mode.
both copies i tried to download.
did you ever find a solution??
sounds like a handy piece of software i'd like to add.
Great! It looks like i'm gonna try it on my Apache..

Well the file only contains the drivers for the Apache and the ESN change program, but if you can find the Hero drivers, the program in the rar should work fine.
thank you
i cound not understand very much
Does anyone know information about how to connect the Samsung Fascinate as Diag Mode driver? ie: this type of connection needed for QPST/QXDM/CDMA Workshop.
I tried 'debugging mode' enabled from the settings in the Applications, but it didn't create any new port that would recognize for my phone.
The Epic solution is pretty strait forward
Install USB Drivers:
32 Bit or 64 Bit
Put phone into DIAG mode:
Dial ##8778#
Select UART = Modem, USB = Modem.

This doesn't seem to work on Fascinate though.
Go to Settings - Wireless Networks - Click to Dialup Networking this will also put it in Dialup mode

Remember to put it Again Dialup Networking off
Thank you for the steps. I was also able to get the phone to be read by QPST and CDMA Workshop. The odd thing is that when I tried to read the phone again the next day, none of the software will read the phone. Interestingly, I can see the COM port and the Modem port in the Device Manager, but the software refuses to read the phone. I am wondering if I accidentally changed one of the settings to turn it into UART or something to this effect, but the code that I found for this (##UPST#) does not work on the phone, even with hidden menu enabled. Any suggestions, currently I am stuck with a phone that can only do voice and text, no 3G? Thank you in advance!
You could try Diag mode
Diag/Testing Mode
*#4636*1111#
QPST sees it, but nothing is editable, in Dial-Up mode?
Thank you for your response! I tried that, it took me to the menu, plugged the phone to the PC, Device Manager shows Samsung Diagnostic Port, I use CDMA Workshop to try to at least read the phone. I connect to the correct COM port, but CDMAWS fails in reading it. I don't get it, it used to work fine with almost the exact same setup. I uninstalled the drivers, reinstalled them, same thing. Wiped the phone, same thing. Kind of frustrating. The only resort I have now is to maybe just get it fully flashed to stock so that I can start from scratch again. Odd, I have never had a phone that was giving me a COM port that phone software consistently fails to read, especially when it worked before. lol. Any assistance with anything else I may try would be greatly appreciated.
**usbui select Modem.. and
Bringing this issue up.... I cannot get it to work. I've read tons of threads and everyone says go to Device Manager and click Ports and then change the port on the Samsung to port 1 and it will show up blah blah Blah.... there is no list that says "Ports" in Device Manager. I have this DialUpNetworking thing checked and debug mode and the port1 shows up in QPST but it says "No Phone". And yes all drivers are installed.
Diag/Testing Mode
*#4636*1111# ??????
That doesn't do jack. It just lets me input the numbers and when I press the last #, all the numbers vanish. I need this to work or I have to get a different Phone.

Do a search in general...i posted how there. It's like *33 something.
**33284 is what ur looking for
Edit: you need to set up the com. That requires knowing the port and putting the phone into dial up mode.
TRY **USBUI (**87284)
You can switch the UART and USB from PDA to MODEM here.

No, I know exactly what he's doing. The phone needs to be in network dial up mode. But for qpst to reckognize it, he needs to add the com.
I found that only the .323 version of qpst worked for me. Also there is the *229 (i think) will reprogram those settings you may have messed up, maybe try that?

323 works for basic flash, however if he's trying to get ppp configs setup for 3g and what not, he will need build 215. 323 will always revert to the original settings. If he's just trying to flash the prl, then it's no big deal. If he's trying to flash over to a different carrier, then it'll revert to vrz settings.
Menu > Settings > Wireless & Networks
Enable Dial up Networking
Next..
Menu > Settings > Applications > Development
Enable USB Debugging
-------------------------------------------
If Dial-up Networking is not showing perform the following. Dial **33284 followed by SPC (000000 or 468346 ) then scroll to Port Map and select HFK,DIAG. Once this is complete, you should now have Dial-up Networking showing up under Wireless and Network.
Bypass Activation:
Press "Emergency Call"
Dial *#83786633 then press send
After you press "send" press the "home" key and you should now be passed activation
this worked in getting the fascinate into daig mode. thank you!!!

alright, So on my GSM HTC 8x (T-Mobile), I got File Explorer working in QPST. I can read and write various NVram values, change band prefs, etc. One thing interesting I found in the File Explorer (Not Windows OS, but for the Fileexp for the modem) is there is a directory called "Supl". In it is a file called "SuplRootCert". I copied it to my PC, and renamed it to "SuplRootCert.cer". When I opened the file, it presented itself as the "T-Mobile USA Root CA". Trusted Root Certificate.
I wonder what this is doing here? It can't be for Wi-Fi calling because the firmware doesn't support it (although it did at one time)..I wonder if we can put our own root certificate here and if the phone will trust it?

The name of the certificate reminds me something about A-GPS, but I could be wrong....
But there is something very intriguing in your experiments: perhaps that way we could enable LTE on the international ATIV S.

I have something you ca try with your Ativ S, if you want:
Try installing the diagnosticApp_Sprint onto your Ativ via the Microsoft Store (Set OEMID to HTC and CID to "null") Then see if you can toast your way to app://e69a2877-59b8-43ed-898d-554fbc4b8b2b/_default#/EmbeddedTool;component/DMSwitchPage.xaml Once there, you can try toggling one of the switches (both will enable the necessary serial Port). When the phone auto-reboots, you should be able to connect it to the PC. Once Windows Update finds and installs the drivers (I am assuming it will do this for the ATIV S), launch the "QPST Service Programming tool" (QPST can be found on the forum if you search for it) Once that tool loads, pick out your device and click "connect". Once that loads, click "read from phone". now go to the UMTS System tab to set your band preferences. (My 8x had all of them enabled by default) (I have nothing to compare it to, so YMMV). Once you have made changes, just press "write to phone" and wait for it to reset. Hopefully then you will have LTE enabled!

You can do this with samsung diagnosis, open it and enter *#7284#, then select QC RmNetComposite. After doing whatever you want, you can go back setting it to MTP again.
The phone will reboot when you change this value.

Obviously, the new version of the diagnosis app (the one included in the official GDR3 update) inhibits that code...I think I will decide myself to restart from GDR2 and upgrade with the "polish" hack, in the end. I was too lazy to do it, Now I have at least a good reason to do it....

How did you do that? I mean... I have a GSM HTC 8x as well and I'd like to edit the registry (mainly to change roaming preferences, bands preferences and if it is possible, the accent colors). Is that possible?
I have installed the Sprint Diagnostics app but it only shows the IMEI info and the SIM card info, nothing more. It does absolutely nothing else. Am I missing something?
You need to install @cpuguy's Native Toast Launcher
and paste this inside the box.

Oh well, no problem with that. I'd like to know if I can enable the AWS band on my phone (I got the c620e version). By the way, working with the modem, can I set some MCCs to be recognised as "home" network? Because I use a MVO and the whole time it says it is roaming (when it actually isn't).

I did all of that on my HTC 8x (model c620e) and it did work. However, I'm kind of stuck because Windows doesn't detect the appropriate drivers for the phone and all I got is "HTC Composite device". Do you have any driver that I can use?
@cybermiguel It did that to me at first, too. Make sure the PC you are using has Internet, right-click on the "HTC composite device" in device manager, select "update driver software". Then tell it to search automatically for drivers. They will "magically" appear.

The screenshot you posted seems to me unuseful: all is already enabled and activated. Can you please post a screenshot of the NAS tab? There you should find if LTE UE OP classes are enabled, and, first of all, if UE RAT includes LTE or not.
Working on the LTE bands (VZW s5 -> ATT sim). I was able to get QPST to see my s5 and perform a back up. The QPST Programmer can also see and read from my phone.
The problem is I launch QXDM (as admin) and it doesn't connect through. Just states "No Connection". All of the ID's on the NV Browser are greyed out. I have been unable to find anything like this so far and was wondering if anyone else had the same issue and was able to fix it. If I find the fix I'll reply here with what I found.
QxDM Production build 03.12.714
I would have asked in the QPST thread but it was locked.
Found it but just in case...
"File > Load Items" gives you the screen to connect into your device.
Hi guys!
My friend @Ajshal gave me his modemst1 and modemst2 files to fix my VoLTE 4G on LG K420DS. I flashed both of those files on my phone and from then my IMEI was 0 because of which I couldn't I couldn't text, call or access data through my sim card.
"modemst1" contains the IMEI information for the phone. "modemst1" and "modemst2" is unique for your own phone! I learnt my lesson!
Requirements:
Windows 7
LG Mobile Drivers
QPST
Your Phone's Original IMEI
Click to expand...
Click to collapse
If you have IMEI "0" or "null" you can use my guide to fix the IMEI
I fixed the IMEI of my phone using the following steps:
Keep your phone's screen turned on at all times while doing this procedure.
(1) Install LG Mobile Driver. Get the Driver from here for K420DS. Select "Software Update" Tab. Download the related driver for your own operating system.
Connect your phone using USB to the computer. Make sure, Developer Options > USB Debugging is enabled.
(2) Install QPST (Version: v2.7 Build 4.11). (Sorry I can't link the software here. Google it)
(3) Open "QPST Configuration" which is the QPST server.
(4) Select Ports. Then select "Add Ports". Untick "Show Serial and USB/QC Diagnostic ports only".
(5) Add the both ports which show up as "... USB/Unknown" and "... USB/QC Data Modem".

(6) Open up "DialUp" app on your phone. Dial "*#546368#*420#" (without quotes obviously) and you are in the LG K10 hidden menu.
(7) Select "SVC Menu". Then select "Port Check Test" and Enable it!
(8) Now in QPST Configuration window you would be seeing a window similar to this. The change here is that your phone's Qualcomm Diag Port is enabled. QPST Configurator shows that "1 Phone" is connected.
(9) Don't close the QPST Configuration Window!
(10) Open "File Explorer". Navigate to "C:\Program Files (x86)\Qualcomm\QPST\bin".
(11) Open "RF_NV_Manager". Select Options>Comport. Select the first "Comport" in the list.
(12) Then select File>Read From Phone.
(13) A window open's up similar to this.
(14) Select "Customize NV Items List". In the "Available NV Items List" select "550 NV_UE_IMEI_I". Click Save.

LG K420DS/N is a dual sim phone. This method allows you to restore the IMEI 1. I am yet to find how to restore IMEI 2.
Is obvious that both modem partitions contains that info. . .
Don't know why you didn't know that? xD
BTW, many thanks for the guide!!!

Hi guys!
My friend @Ajshal gave me his modemst1 and modemst2 files to fix my VoLTE 4G on LG K420DS. I flashed both of those files on my phone and from then my IMEI was 0 because of which I couldn't I couldn't text, call or access data through my sim card.
"modemst1" contains the IMEI information for the phone. "modemst1" and "modemst2" is unique for your own phone! I learnt my lesson!
If you have IMEI "0" or "null" you can use my guide to fix the IMEI
I fixed the IMEI of my phone using the following steps:
Keep your phone's screen turned on at all times while doing this procedure.
(1) Install LG Mobile Driver. Get the Driver from here for K420DS. Select "Software Update" Tab. Download the related driver for your own operating system.
Connect your phone using USB to the computer. Make sure, Developer Options > USB Debugging is enabled.
(2) Install QPST (Version: v2.7 Build 4.11). (Sorry I can't link the software here. Google it)
(3) Open "QPST Configuration" which is the QPST server.
(4) Select Ports. Then select "Add Ports". Untick "Show Serial and USB/QC Diagnostic ports only".
(5) Add the both ports which show up as "... USB/Unknown" and "... USB/QC Data Modem".
(6) Open up "DialUp" app on your phone. Dial "*#546368#*420#" (without quotes obviously) and you are in the LG K10 hidden menu.
(7) Select "SVC Menu". Then select "Port Check Test" and Enable it!
(8) Now in QPST Configuration window you would be seeing a window similar to this. The change here is that your phone's Qualcomm Diag Port is enabled. QPST Configurator shows that "1 Phone" is connected.
(9) Don't close the QPST Configuration Window!
(10) Open "File Explorer". Navigate to "C:\Program Files (x86)\Qualcomm\QPST\bin".
(11) Open "RF_NV_Manager". Select Options>Comport. Select the first "Comport" in the list.
(12) Then select File>Read From Phone.
(13) A window open's up similar to this.
(14) Select "Customize NV Items List". In the "Available NV Items List" select "550 NV_UE_IMEI_I". Click Save.
(15) Now you would be seeing an option to select "550 NV_UE_IMEI_I". Select "550 NV_UE_IMEI_I".
(16) Convert your IMEI to Hex Values. You can convert your IMEI to Hex here.
(17) Select the "Hex" checkbox. Enter those Hex Values into the text boxes. Enter two values at once into the textbox. For example, if your Hex output is "08 3A 75 (etc.)" type 08 in the first textbox, 3A in the second textbox and so on.
(18) Select "Write NVRAM". Your IMEI is written to NVRAM.
(19) Disconnect the phone from the computer and restart the phone!
Your IMEI is restored!

Hello, I know this is an old post but I would really appreciate it if you answered. I am running Lineage Rom 14.1 latest official build and I lost my imei because I flashed the newest twrp by mistake and then changed it to your build from scratch 3.1.1 as I was supposed to so I could flash updates. I am 100% sure this is a solid guide and I appreciate your work on the Lg K420N but the secret dial codes don't work on my phone.Is there another way to do this ? On a side note I'd like to ask if there is a way using Windows 10(Windows 7 are really slow on my computer because my computer is old)

Well I managed to run qpst on windows 7 after all and the imei was already written on the phone when I used RF_NV_MANAGER
but sadly this is as far as I can get with it, IMEI Information on the phone says IMEI and IMEI SV unknown.
Could this be a result of dirty-flashing a LOS update using twrp?
