Help me! I am using GALAXY S10 (G973U, AT & T, SIM unlock). When I tried to add an LTE band, I used QXDM, but when I first connected it worked fine, but from the second time I did not recognize well due to an error. (The device is not recognized even if the device is selected is COM: 0.) The driver uses the SAMSUNG DIAG driver. Do I have to use Qualcomm's diag driver? If you can't go without it, which driver should you use? Also, even if I select it in the NV browser, the message "diag error received invalid command error response" is displayed and the settings cannot be changed. I don't know what to do. Please help someone

Okay, so Im trying to do a PRL update on my Virgin Mobile LG Optimus V. I downloaded all the required software (CDMA Workshop, QPST v2.7.323_(2008-09-19), and the newest PRL for Sprint 60683). I installed the LG Universal Serial Drivers v3.3, and then installed CDMA Workshop. I opened Device Manager in Windows start menu, checked the current port of the LG Android Platform USB Serial Port (which is set to COM2), I then enabled USB Debugging on my phone, opened CDMA Workshop, clicked the drop-down menu to connect to port COM2, and it connected, BUT sometimes it randomly doesnt connect. After it successfully connected to COM2, I clicked on the "Security" tab in CDMA Workshop, clicked the drop-down menu under "SPC / User Lock" and changed it to "LG method", and then clicked "Read", itll start to attempt to read, and then in the bottom of the window in CDMA Workshop, it says "Failed..Phone does not answer".
What in the world is going on? Ive tried rebooting my PC, reinstalling the drivers, restarting CDMA Workshop, and changing the ports up but it NEVER reads my MSL!!! Do you all know whats going on? Is it becasue im running IHO BACKside CyanogenMod 7.2? Do I have to be using a Stock ROM when retrieving my MSL? I even tried the method of logging into my Virgin Mobile account, and then clicking that link (this https://www1.virginmobileusa.com/myaccount/login.dofsdf that says Error 404 not found, but the page doesnt even say a 404 Error, it says "The specified URL cannot be found".
What do i do guys???
Get MSL LG Optimus Black
I Am Not 100% sure this will work for your model but i downloaded LogCat to my PC and searched the code is under
D/InfoItems( 1572): Msl is filled as : 111221........................ hope this helps... your MSL probably isnt the same but it worked . you may have to search in the edit box for msl and just keep clicking down til u find it.
Hi,
im following Ryan Mogul's instructions for the ppc 6800 to unlock the SPC from the code to 000000 , ive gotten to the QPST add port and there is no phone listed , any ideas ?
thanks
Posted to wrong section please move to general q's mod!
Also more info , ive installed the diag cab it works flawlessly and also dialing the code on the phone gets you into diag . But when plugged into my laptop , win7 64 bit , it does not show up in qpst when i add port. On device manager it has a yellow triangle , indicating driver issue i believe ? I saw a thread days ago about using a set of drivers posted here by another user ?
Anyone ? Any help is appreciated i want this phone activated on cricket to use for wireless tethering
did you put the phone in diag mode? ##diag#
yes,
in Ryans instructions he has you install a , "Diagnostic Shortcuts cab" which gives you access directly to the application on the phone so you dont have to dial codes , same as epst , if you use the file manager you can just go to the windows directory and open epst , so i opened that and followed his instrutions to let the app start and when in diag mode the program would just hide itself , i did that and then tried to find it on QPST with the add port option and nothing shows up
epst and diag mode are different. flash back to stock and put it into diag, then write the SPC to whatever.
Hello,
I'm here trying to get help to solve a LG L65 D280n with the null IMEI problem.
I'm hopping there's no problem with the hardware as it was working ok and didn't fall or something else. It just got that way and it was nw unlocked some months ago.
Well, I've 1srt search and follow many youtube videos and read a lot of threads.
At 1srt I've tried to use official software form LG. LG mobile tool and drivers.
I download and install them everything goes well, phone is detected and after usb connection the firmware download started.
Problem was, after the point that it decompress the firmware and it was supposed to start copying it to the phone, the LG app just hangs with the windows error as it stops responding.
Using a machine with Win7 Pro x64.
From this saved the LG kdz file and the dll file that was downloaded.
I can't get another because the links from:
http://redirect.viglink.com/?format...g-phone-firmware.com/firmwar...-Tutti-50.html
are broken to the Europe/Portuguese version A or B of this phone that was original from MEO/TMN
Then I've tried another LG tool, older I believe. It requires qualcomm software, visual c++ etc.
All went well until I've selected a com port at the QPST configuration and then at the RF NV manager were I would try to write the IMEI it fails.
I select the COM port I've added before at the QPST configuration app but when I select the READ from phone option it just returns error ... DM command 19-24.
I was hopping to flash the modem only or to write the IMEI manually but its getting hard to solve the communication problem even after trying in different computer and with 3 version of drivers and software.
Recovery mode only shows if I wanna do factory reset, I did.
Can someone help?
Tried also EFS Professional now using Qualcomm NV tools, I can select the phone COM port but if I try to connect to it with 000000 Send SPC option on, It returns error, unable to send SPC to the phone.
I recently tried installing this rom https://forum.xda-developers.com/vivo-5/development/rom-aosp-6-blu-vivo-5-clones-t3489281 but it did not work very well.
It is now appearing as invalid IMEI.
Any idea what I can try?
I've tried the MTK Droid tool, MAUI, SN Writer but none of them recognize the smartphone.
Try with this:
PD: Have you problems with WiFi?
For a temporal solution you can use MTK Engineering Mode (The Monster) from the Play Store. I think maybe you need to be rooted.
MTK settings
Connectivity
CDS information
Radio Information
you will see AT+, delete the plus , add the plus sign choose the first option (in my case AT+EGMR=1,7,"")
Put the your EMEI in between the comas "EMEI" if theres an error put a space between the + and EGMR
for the second EMEI select the second option AT+EGMR=1,10""
This will work until the phone is reset

I have had an unlocked VS985 for three years now overseas and its been flawless so far. It all started when suddenly one day the SIM failed to be recognized. I put the SIM in an another phone and it works fine. No other SIM card gets recognized on the device. These are a summary of things I've tried so far:
1) I initially thought flashing another ROM would fix it, and I tried like 3-4 ROMS available in XDA (thanks to all the devs!!). Nothing helped. The SIM continued to be unrecognized in all the ROMS. I then flashed back the stock ROM by the TOT method.
2) I then suspected it could be something with the phone radio and started investigating in that direction. I tried enabling all the bands through the shortcut app and that too did not fix it.
3) I found the hidden menus to attempt turning on/off the radio but found that I was unable to enter what's called as "Phone info" hidden menu (picture attached) that contains this radio on/off option. Although it didn't let me enter I noticed that the phone IMEI in that menu was missing the last digit. The IMEI in the Setttings -> about phone (or below the battery) shows an IMEI with the same digits but with one extra number at the end. I suspected that somehow this IMEI mismatch of the last digit IMEI was the reason the phone is blocked for all cellular connections.
4) I then tried fixing the IMEI with the Qualcomm QPST method but unfortunately unable to enable the DIAG USB ports. I tried that with adb commands with terminal emulator and all the commands are accepted without an error. But when I connect the phone with debugging the appropriate COM ports don't show up on the QPST configuration. I also tried that with the phone hidden menu (##7764726985) but the "Port check" option that must show up is just not there.
I am stuck now. I am not sure what exactly has happened and if my diagnosis on the IMEI is valid. A phone service center tells that the SIM slot is good and this is a software problem. Can someone please help me fix this? It could be a simple fix to access the DIAG USB port or a bigger fix to the whole problem. I just don't understand how the IMEI could have randomly changed when it was fine for all the 3 years thus far. It has been a harrowing 2 weeks trying to find a solution and I'm tired. Please HALPPPP!
EDIT: I was able to get into the debugging mode and was able re-write the correct IMEI. I restarted the phone and still its the same as in the first picture, missing the last digit. May be as a consequence, the phone is unable to recognize SIM or letting me access this menu
I received the SIM card unrecognizable alert, with my original G3. I took it into a VZW store and they told me it was a hardware failure. They replaced the phone on an insurance claim. Never had the issue again. I don't have any experience IMEI issue.
