QPST doesn't detect G2 D800

I'm trying to follow this guide to enable extra LTE band on my g2 d800.
Through hidden menu 3845#*800# I have set port settings -> Diag Setting -> USB
Also I've enabled Hardware key mode (all three back button on powering on -> Mode on)
However, QPST is unable to see my phone. I have to disable Show serial and USB /QC diagnostic port only to see the phone modem port. Also even after doing that and adding it, qpst doesn't detect phone
Any ideas of what might be causing it ? I'm using Windows 7 64-Bit as OS and Cloudy 3.3 w/ dorimanx 4.6 kernel and USB mode set to MTP

Dont bother. The bands have to be programmed into the radio antenna. Even if you do set the files to allow those bands without it being programmed into the antenna it wont do any good and you run a good chance of messing something up

Ok thanks As i found out also, it doesn't work on G2 but didn't know the reason...
BTW if anyone is stuck with same problem i.e. QPST not detecting port do below commands via adb shell
su
setprop persist.usb.eng 1
setprop usb.rndis.enable 1
echo 1 > /sys/devices/platform/lg_diag_cmd/diag_enable
setprop sys.usb.config acm,diag,mtp,adb

[Guide] How to unlock McAfee lock LG G3 (US990,LS990)

Hello from sunny Moldavia.
I found a method to bypass a blocked MсAfee. This is post about unlocking LG G3 USCellular - US990(and Sprint LS990), but you can unlock any G3. (all you need - tot file from you G3 and some partitions from non-locking G3)
Link to my site for thanks)
Instruction on russian language: http://4cdma.ru/news/39-snyatie-blokirovki-mcafee-na-lg-g3-us990-ch1-poluchaem-dostup-k-rekaveri.html & http://4cdma.ru/news/40-snyatie-blokirovki-mcafee-na-lg-g3-us990-ch2-poluchaem-dostup-k-download.html
1. Download https://www.androidfilehost.com/?fid=24269982087002399
2. Extract LGG3US990_McAfee_9008.rar for US990 or LS990ZVA_4_BoardDIAG.ZIP for LS990
Step 1. Open the Windows command prompt as “Run as Administrator”.
Step 2. Run
Code:
Code:
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
Step 3. To finalize the process run
Code:
Code:
bcdedit -set TESTSIGNING ON
Step 4. Reboot and you’re done.
I have attached both the 32 bit version and the 64 bit version be sure to only use the 64bit one on 64bit and likewise only use the 32bit one on 32bit, you do not need both sets of drivers.
1. Open your phone and take out the battery. Remove the top half of the phone housing. You do not need to remove the bottom half by the usb. Also you don't need to remove the screw next to the camera. If you do remember that it is a different size so keep it separate.*
2, You will see a big metal shield. You need to remove it. It is pretty easy just pry it off and it pops back into place when you are done.
3. Next you need to short the pins as shown in the following picture. While continuing to short the pins plug in your usb cable. You should hear windows detect the phone almost instantly. Keep shorting the pins for the count to 5 and then you can release the wire. See image below in attach file
4. Now open device manager in windows and it should show your phone under com ports as Qualcomm 9008 (COM #). If it doesn't try the process over again. When it does work remember this number. It is going to be used later.
5. Now fire up BoardDiag by willcracker be sure to run it as administrator. It is in this post named willcracker.rar There are some pictures on how to flash with this app but I will describe it as well. First we are going to need to extract your tot file. This can take some time. Like 10 mintues on a decent PC. The app may look like it froze up but it is just thinking. When it is complete move on to the next step.
Click to expand...
Click to collapse
Now You need to tell the program the com port that you are using that we found earlier and the folder where you extract the firmware. In LGG3US990_McAfee_9008.rar has folder "img10c". Select it to Target Dir.
once you have extracted the firmware and set up the program with the correct port you need to Check "AP" and "EMMC" then press start. After test passed ok you will check*RESTORE BOOT IMG and flash all of the partitions except for Cache, System, Userdata, and Sbl1. Sbl1 will be flashed later and causes the phone to reboot.
Click to expand...
Click to collapse
After you flash all partitions in BoardDiag. Switch off the phone and make a factory reset (if you dont know how - link http://www.hard-reset.com/lg-g3-hard-reset.html)
After you make a factory reset - you will see TWRP recovery welcome logo and phone switch in Windows on ADB mode and install ADB drivers. (If not - switch off/on ENABLE *MTP in MOUNT TWRP section)
Than download this link for US990 20a_dd_files.rar or LS990 zv4_dd_files.rar, extract him, and run repair.cmd
After flashing by repair.cmd script. Switch off the phone. Then press and hold the “Volume Up” and connect the USB cable from phone to PC. You will see a Download mode and you CAN now flash phone by FlashTool via tot or kdz file.
Sorry for bad english and subscribe to my youtube chanel https://www.youtube.com/channel/4cdma

What will achieve with this?

this method has bricked my g3 f400l
i have flashed all them and i have no data system cache, LGUP detect it's us990 and i cannot flash f400 firmwares

It may be possible to only have to flash 1-3 files, instead of most of them. I don't have an extra LG G3 to test with, So if you want to check out my experience with the killswitch.

[Guide] Enable Volte on custom rom (Android 10) (Rooted)

Disclaimer: I do not know the underlying working of what this procedure does. Just sharing what's working for me. I do not take responsibility for any problems which might arise from following this guide. Please proceed with caution.
I have tested this on the Oneplus 3t and only for airtel india. Please feel free to experiment and report for other carriers.

This guide will proceed assuming that Volte is working on OOS 9.0.6 for your carrier and does not work with the custom roms.
prerequisites:
For mobile
Unlocked bootloader, TWRP (Latest)(or some recovery based on twrp like shrp)
For PC
QPST and the requried qualcomm drivers which comes bundled with QPST , Minimal adb and fastboot
Files
OOS 9.0.6 , any android 10 based custom rom for which atleast someone has mentioned volte works on, A root option that you prefer
Make a complete back-up before proceeding.(Some say having a efi partition backup is good idk why I think it has the imei details and stuff)
1 . Flash OOS using twrp then Flash recovery (twrp) zip or img (Flashing OOS generally flashes back the default recovery)
2. Using the inbuild file explorer in twrp navigate to /system/etc/firmware/ and copy over the mbn_ota folder to your internal storage and move it over to your pc.
3. Flash the custom rom, gapps(if needed), root solution of your choice and boot up. Get the initial setup done and check if your network is working.
4. Enable adb and connect your phone to your computer.
5. Open up cmd in your minimal adb folder
and type in (or copy) what's given line by line:
adb shell
su
setprop sys.usb.config diag,serial_smd,rmnet_ipa,adb
(Or)
type in
su
setprop sys.usb.config diag,serial_smd,rmnet_ipa,adb
in a terminal within android (download from playstore or install using apk)
This will enable serial over usb needed for use with PDC until you change the state to mtp or tethering or restart
6. Open PDC(as admin if required) from the qpst folder.
7. Select the device. Check the links provided to find out how to enable profiles in PDC. From my experience you do not have to remove any profiles from your device using PDC.
8. If the required profile is not present then use the load option to load in the required .mbn file from what you had copied from oos previously. ( I used mcfg_sw_Airtel-Commercial.mbn for airtel ) and activate the profile.
9. Might not be required - To force enable Volte in your rom add these lines to the build.prop file
persist.dbg.ims_volte_enable=1
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=1
persist.dbg.wfc_avail_ovr=1
persist.radio.rat_on=combine
persist.radio.data_ltd_sys_ind=1
persist.radio.data_con_rprt=1
persist.radio.calls.on.ims=1
10. Reboot phone

Got stuck at PDC
I was successful in installing QPST and the device shows up in the Device Manager as a Qualcomm USB Modem connected to COM9. It even shows up in QPST config. But PDC shows no devices (even when run as Admin). Any help is appreciated . Thanks.

Did you install the Qualcomm usb driver which came included in the QPST zip file.
I'm not sure if it is a problem with the qpst version ,I'm using QPST 2.7.480.
And once I run the command in adb shell I get my device to show up as Qualcomm USB Composite Device in device manager under the universal serial bus controllers category.
And if everything is working well , the pdc will not show anything when it opens up but you'll find your device in the drop down menu.

I have installed the same version. My device shows up in two places - under Modems and also under Ports (COM & LPT) as Qualcomm HS-USB Diadnostics 9091 (COM9). It's not showing up under USB controllers but. The PDC device list dropdown is still empty.

To activate a profile: Right click on it and under setselectedconfig select sub0/sub1/both (try and check what works for you) and then you'll be able to click the activate button.
To deactivate select the sub under deactivate in the right click menu (or) just activate some other profile .
Do check the other xda forum posts related to this which i've provided links under reference, it might be helpful when you're stuck with something related to this .

I've tested it to work with luisrom,Havocos and some other rom I don't remember which one.
Running the command doesn't bring any popup or open up anything on the phone but you'll be able to see the change in the device manager of your pc.
The change caused by the command only persists till it is connected (ie. if you unplug nd replug the usb cable it will revert to the default state), until you change the state from the option provided in your notification (ie . something like from charging only to file transfer or tethering ect) and restart of the device.
Do also check if you have the correct drivers installed.

The phone need to be switched to diag mode.
Before doing this Mod you should backup EFS-partition !!!
Need to have adb installed and phone rooted. Open cmd window and type:
adb devices (check if phone connected)
adb shell
su (grant root)
setprop sys.usb.config diag,serial_cdev,rmnet,adb
You will find new device in PC device manager "Qualcomm HS-USB WWAN Adapter 9091", then PDC tool will recognize your phone.

In device manager you have "Qualcomm HS-USB Modem 9091" and not "Qualcomm HS-USB WWAN Adapter 9091".
Few weeks ago I changed my modem config using this method. I used Xiaomi.eu 20.7.9 MIUI12 weekly ROM. Or try to change the qualcomm drivers.

Tried to enable VoLTE & VoWIFI on my Redme 9 Pro, using the PDC and can actually get the VoWIFI works. However, once the device reboot, it just fall back to the ROW_Commercial profile and have to redo again to get it work.
Do not know if this happened on other Redmi series?

Very much thanks for this information

[Guide] VoLTE/VoWiFi/ViLTE/EVS HD+ codec [no root] latest OOS 11.0.7.7

To be safe, make a backup via TRWP of your EFS partition BEFORE you flash anything! If you're not rooted, do a nandroid backup via fastboot
Steps:
1) Set your stock dialer app as default
2) Download and install “Logkit+v1.0.apk”
3) Open dialer app and enter *#800#
Scroll down to Function Switch and then tick-mark the “VoLTE”, “VoWifi” and “VTSwitch”. Exit from app and reboot phone. Go to Settings->Wi-Fi & Network->Sim & Network->Sim 1 and enable “VoLTE” & “Wi-Fi Calling” options. Repeat step for SIM 2 if necessary. Reboot phone.
4)Download and install to PC “QPST_2.7.496” + “qud.win.1.1_installer_10061.1.zip”
5) Enable Developer options and “USB debugging”
6) Download and install “engineeringmode_V1.01.0.171117173719.25c8842-26.apk”
Open dialer app and enter *#801#
Set “Full-port switch” to ON
7) Connect your phone to PC via USB and allow USB debugging on phone
Run ADB as administrator (if you haven’t download and install to your PC)
In CMD:
ADB reboot ftm
You should see some Chinese characters on display
8) Go to Device manager. You should see two "IN2010" devices in "Other devices" section. You need device with PID "MI_00", in my case it's second one. You could check, who is MI_00: Right click on device, properties, Events tab (look at screenshot).
When you find correct device, right click "Update Drivers", "Let me pick from a list...", select "Ports (COM & LPT)", select "Manufacturer -> Qualcomn Incorporated, Model -> Qualcomm HS-USB Diagnostics 90B6"
9) In CMD:
ADB shell
setprop sys.usb.config diag,diag_mdm,qdss,qdss_mdm,serial_cdev,dpl,rmnet,adb
10) Run “as administrator” PDC from QPST package. Select “Qualcomm HS-USB WWAN Adapter 9091” from list. In some cases PDC can’t connect to your phone. There is a strange solution:
Run EFS explorer from QPST package “as administrator”, select device with filled "EFS" and "Banner" fields and connect to your phone. In the moment of connection PDC works as excepted. Listing of EFS explorer takes a lot time, but after successful connection PDC stops working again. Close EFS and repeat step to finish all following steps in PDC.
In PDC right click on "Oversea-Commercial_DS" and deactivate “Sub0” and “Sub1”
Click on “Oversea-Commercial_DS” again and click remove.
Select “India-VoLTE-Vodafone”, right click and SetSelectedConfig for both “Sub0” and “Sub1”. Then click Activate button. Close PDC.
11) Download and extract “Audio+codec+EVS+HD+.zip”
Run EFC explorer “as administrator” and connect to your phone if not done earlier.
Backup to PC “overideconfig” and “overideconfig_Subscription01” from “/efsprofiles/” folder.
Replace “overideconfig” and “overideconfig_Subscription01” from “Audio+codec+EVS+HD+.zip” package with “Discard” “Clean-Up Option”. (Right click on file, “copy Data File from PC..”)
12) In ADB:
ADB reboot
13) Install “com.oem.oemlogkit_1.0.200929184727.270d7d2-1.apk” to return stock logkit.
14) Open dialer app and enter *#801#
Set “Full-port switch” to OFF
15) Disable USB Debugging if necessary.
16) Set back your custom dialer if necessary.
That’s all. You have VoLTE/VoWiFi/ViLTE/EVS HD+ codec. Icons in dialer and curtain.
After update to latest version VoLTE was not working again. I think we should repeats this step after every update, until OnePlus (if) fixed this issue.

Hi,
patonovich
Same question. Do you have "Qualcomm HS-USB WWAN Adapter 9091" in windows device manager after "setprop sys.usb.config diag,serial_cdev,rmnet,adb" command in ADB Shell?
Also, what Build number and Model you have? Attach screenshot

Ok, folks. I checked again on clean device and latest version OS 11.0.4.4.IN21AA. there are some changes.
It's seems like QPST need COM device to communicate.
Disconnect your phone.
Update Qualcom driver to newer version (download in attachments 1st post section).
Connect your phone.
After "ADB reboot ftm" command BEFORE entering shell and "setprop sys.usb.config diag,serial_cdev,rmnet,adb" (look at updated command) :
Go to Device manager. You should see two "IN2010" devices in "Other devices" section. You need device with PID "MI_00", in my case it's second one. You could check, who is MI_00: Right click on device, properties, Events tab (look at screenshot).
When you find correct device, right click "Update Drivers", "Let me pick from a list...", select "Ports (COM & LPT)", select "Manufacturer -> Qualcomn Incorporated, Model -> Qualcomm HS-USB Diagnostics 90B6". After that, enter to ADB shell and use command "setprop sys.usb.config diag,diag_mdm,qdss,qdss_mdm,serial_cdev,dpl,rmnet,adb" (edited). You should see your phone in EFS Eplorer and able to connect (select device with filled "EFS" and "Banner" fields. look at screenshot).
After update to latest version VoLTE was not working again. I think we should repeat this steps after every update, until OnePlus (if) fixed this issue.

Do you have VOLTE supported and activated by carrier? Be sure using Sim slot 1 also.
