I have a rooted and bumped LG G3 D855. I have been investigating enabling additional LTE bands using QXDM, QPST, CDMA workshop, etc. and have accidentally changed my SPC code. Initially the phone would accept the default SPC of 000000 but now it will not. I have an EFS backup from TWRP. Can anyone help me examine these files to determine my "new" SPC code?
I can still continue my LTE work using QXDM since I can still write to certain NV items without the SPC code but I would still like to recover it.

I have hit a hard wall trying to rewrite 2 NV items when in diagnostic mode. Any ericsson cdma gurus might be able to provide some guidance? I belive I am going to need to scan memory for all entries associated with the values I need to change and then rewrite them but when I do this I get a reboot and no output. I have been able to rewrite the entire phone with all values and settings I need except these last 2 items. I have been working with CDMA workshop, qdxm, qpst and DFS.

Hello,
I am playing around with QPST RF NV Manager.
Whenever I do a change to an NV item, and write it back to the phone, the application does not complain or anything. But when I read the NV items back from the phone, it shows me the original value (my change is not there).
I tried working with QPST Service Programming, and it has the same problem.
Also I tried QPST software download to back up the NV items. Using xxd I converted the backup to hex file, did my changes in the hex, using xxd converted the manipulated hex back to binary format, Then I restored the NV items on the phone using the manipulated backup and it again does not have any effect.
FYI, I also played around with EFS Professional 2.072 and the changes also does not take place!.
Is there any setting somewhere that I need to change to make the changes for sure to be written into the phone?
BTW, when I put the phone in download mode (this was not when I was working with QPST stuff) I noticed that a grey text says: "Write protection: Enable". I wonder if this has any relationship to QPST problem!?!?!
Setup Environment:
Galaxy S4 T-Mobile Version.
4.2.2 Stock (Rooted) and sim unlocked.
Under QPST I see the correct port which detect the phone (under phone column I see a code and (0) )
Any hint will be appreciated.
Thanks
Did you find a solution to this?
Hi all,
I've been trying to get a used i317M to work on the Wind network. I tried several times to use the .qcn AWS unlock here with no success (only "Wind Away" network found). So I then tried to edit a NV text backup taken with the Qualcomm NV tools in Gaz's "EFS Professional" and write it back. Big mistake.
I'm now locked out of using any Qualcomm tools, the SPC isn't 000000 anymore apparently. "Wind Away" is still the only network I can see.
I've tried flashing radios (only Canadian i317M versions), and roms (like these root stocks). No improvement.
Using the CDMA Workshop free NV-items reader, I got another .txt dump (except for items secured by the new SPC). Comparing the two shows changes in many places across the NV settings. I can share the text files (minus IMEI) if it will help narrow down the problem.
So, what should I try now? I have:
Root
.qcn backup of NV-items
.txt backup of NV-items
TWRP recovery working
efs backup (taken after the NV screwup... yeah i know)
I don't have
SPC
MSL (typing getprop shows no MSL in the list)
an intact Knox flag
Any ideas?
This is just a guess but maybe reflashing the modems will help

Hello,
So currently my MEID is all zeros according to DFS. My ESN is B0000000 in DFS as well. In my phone settings it shows that my phone number is 000-000-0016. Also shows a different MEID in my settings: 17600000000
When I trry to change my MEID/ESN number in DFS I get the error:
"CPS_ERROR BAD_SPC_MODE"
How do I fix this. I alrady know that my SPC is 222222 and it says device unlocked in the logs.
So after tot back to stock, my phone refused to activate and prl/ profile updates fail with authentication error, and it fails to activate with "activate this device" in the settings menu.
No efs backup, and when i called sprint they tried to have me program it manually with the msl, but the msl they gave me failed. 000000 worked, and msid is set to 000000008747. Needless to say, the phone call was pointless.
I tried using cdma workshop and the like to write the meid dec, but even though the logs say it was a success but it didn't actually take.
Anyone know if there's another way to write meid, etc? Dialer code or something? I'm looking for a self-fix to avoid going to sprint to use my repair plan.
