QPST doesn't detect G2 D800 - G2 Q&A, Help & Troubleshooting

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

How To Manually Update PRL On CM7

http://forum.xda-developers.com/showthread.php?t=1162091
Thought I would share
oh and the latest qpst
Did you actually test this? I've tried it on two separate occasions (I found that thread a month or so ago) with no success. I tried multiple combinations of UART/USB settings, and plugging the USB cable in before and after starting QPST, as well as turning debugging on and off. Specifically, I followed Leviuqse's instructions (omitting steps I have previously performed, such as installing the drivers):
Install QPST 2.7 Build 323. (I used this version, and have successfully used it with a TW ROM to change PRL)
Install the Samsung Galaxy S Drivers
Uncheck USB debugging
Dial ##8778# to open the “PhoneUtil” hidden menu (*#*#8778#*#* to open SprintMenu.apk)
Change both UART and USB menus to "MODEM" and press [Home] key
Connect your phone to your computer with the usb cable, select “charging” if the select USB mode menu opens
Your computer will automatically install the modem drivers for your Epic. Wait until you see “Device is ready for use”
Open QPST Configurations in Windows: Start > All Programs > QPST > QPST Configuration
Click on the “Ports” tab and “Add a new port”
Select the “COMXX – USB\QC Diagnostic” and click ok, in my case the port number was 10, your port number will be different, if you see more than one, disconnect all your external devices such as external HDDs, phones, Bluetooth dongles, ect. If you don’t see a port. Disconnect your phone, restart your computer, connect your phone and try again, you might want to remember your Epic’s port number for future use
If you successfully got this working while running CM7, please tell me how you did so!
Debugging on or off?
Plug in USB cable before or after starting QPST?
What UART & USB settings? Both "modem"?
Anything else I'm missing?
Thanks!
Doesn't work for me either.
Only method that works is going back to a TW ROM. Not that its a big deal since you only need to flash to 11115 once.
All my E4G's are already on 11115, so I haven't tried this. But this might help
echo 1 > /sys/devices/virtual/usb_composite/diag/enable​
(instead of "echo 1 > /dev/qct_diag_enable" which is for HTC phones).

So on my phone (CM7 Nightly 24) i dont have a diag directory under usb_composite so the command errors out. The only folders i have are acm, adb, mtp, rndis, and usb_mass_storage. attempting to create the diag folder fails.

[Q] Enable USB Debugging tools through ADB in recovery mode

So, my digitizer is broke and I can't see anything or use the touch.
I am able to get into recovery mode with ADB and I tried some echo lines to manually activate debug mode, so that I can have my device authorized to use with ADB afterwards.
I'm trying to use Androidscreencast, but I need to make it work with ADB first and since I get device unauthorized it means that I don't have usb debugging enabled.
The final question : How can I activate debug mode without a screen?
You need to flash a kernel that has usb debugging enabled by default and has disabled that RSA security check.
So I think that what you want is nearly impossible.
I tried to pull and push default.prop and build.prop and I managed to do it, but when I reboot the phone it goes back to the older versions of the files...I don't know why the files don't remain, even though when I check with ls -l in adb shell it is the today's version.
In the end I managed to read my sms, by pulling out the database from the telephony folder and load it with some sql db reading software.

How to Enable Diag Mode in CM13?

Okay so here is the issue I'm facing today. I bought a Sprint Galaxy S5, and I managed to unlock it for domestic use (AT&T). I cannot get an LTE connection because my Qualcomm processor does not have the appropriate bands to use ATT LTE's network.
I read on here that you can write your NV memory to write the firmware and enable these other bands using QPST and QXDM. The issue I'm having though is getting my computer to install the diagnostic driver for COM port. It reads the Modem under modem tab in device manager. Since the computer doesn't think there is a diagnostic port, QPST configuration cannot open a diag port which is what I need. I've been able to successfully put my phone in rndis + DM + modem by using this in emulator,
su
setprop sys.usb.confing_rndis,diag,diag_mdm
Do not type the first _ as it's meant as a space bar, but USE diag_mdm
But there is no indication that any driver has installed, and does not appear in device manager (even with hidden devices shown).
I'm running 6.0.1 CM13 w/twrp recovery with SELINUX set to permissive.
On windows 8
I also noticed that the guide to add frequency bands was written in 2014, I also know that in Lollipop, you needed to enable CP Logging to get it show up.
What I'm wondering is if there is a missing step to properly installing the diag driver, or if Qualcomm/Samsung found other means to activate it.
I noticed that when using EFSPro I can set it to Diagnostic + Modem + adb but I can only read not read/write NV memory
Also I observed when I send the SPC to read the phone with EFSPro, it says
"SPC was accepted by the phone!"
Then followed by.. "SPC was not found".
Then after I close that popup it reads my NV memory, but I can't write.
Is there a method to enable CP logging on CM13 MM and install the diag com port for QPST use? I don't have a stock recovery to enable CP logging through usual means in as I'm using TWRP.

QCN Back Up and Diag Mode

Can anyone please tell me how to enable diagnostic mode on ASUS Zenfone Max pro M1? Is it possible to backup qcn file using QPST?

Yes, you can backup qcn..just make sure that your phone
shows up as diagnostic mode in device manager and is listed under active devices in qpst..then
Qpst->software download->backup

It won't work. Because the phone is not rooted. Is there any hardware key combination for enabling diag mode?
Update: Downloading latest qualcomm driver solved the issue. I was able to choose diag port and back up qcn. Thank you all.

Can you provide more detailed info, please (which mode was set on phone, driver for which device was installed)? It's very interesting, how to restore (or at least backup) qcn without root.

1. Switch off your phone
Open device manager on pc
2. Press and hold vol up+ vol down and plug in the data cable
Now your device must be listed in device manager...if not then repeat step 2 but keep your device plugged in to pc.(.do not remove the cable...)
It takes 2-3 tries and hold the buttons for around 10 seconds...
Once it is listed as diag mode in device manager...
You can backup qcn using qpst

Hello and thanks for the above info. I did this and got a totally black screen. quite disconcerting. I read somewhere else that holding power + volume up would cause it to go into download mode and I was able to do that and then press/hold the power key to power off the phone and regain normal operations.
When in mode you suggest, I do see the device in the windows device manager (however, I have to boot Windows into test mode because of an unsigned driver). When I open qpst it immediately auto-adds the port but it shows that it is in download mode and this never seems to stop. when like this, I cannot open service programming and use qxdm to browse the NV. Any idea what is happening here? Any way to prevent the auto-add and download? I am rather new to all this and am stumped. Thanks

You dont need to do this for just rooting...just unlock bl and flash twrp...magisk
Run from adb if you want to use diag mode

I'm attaching QCN Backup with dummy Imei
1st IMEI hex = 08 1A 32 54 76 98 10 32 54
2nd IMEI hex = 08 0A 89 67 45 23 01 21 43
Replace these with your IMEI hex using any hex editor app
The file attached is ".txt" because xda doesn't support ".qcn"
Make sure you change extension to ".qcn" before doing anything

Thanks. I understand rooting well enough. I was asking about the lack of "setprop" in the instructions originally presented. I have confirmed that this is the command needed and can get my ZB602KL into diagnostic mode and visible to QPST. Now if I could only get QXDM to access the item that contains the bitmap for the LTE bands. It could be that my version of QXDM is too old for this device. It worked fine on a Samsung Note 3. But that is an older, 32-bit device and the Zenfone is 64. I just don't know. I cannot even read most items. Argh!

[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.
Hello.
Does the step 9 has to be done , becouse i cant get a connection with efs explorer. Its just blank. I ask becouse i have volte and vowifi activated but my phone wont turn automatic to vowifi when i get a wifi connection. i have to first turn off volte and reboot that the phone connects to vowifi

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).
