i am on LineageOS 16 and want to enable Carrier Aggregation and when i enter the cmd in termux "setprop sys.usb.config diag,adb" nothing happens and i'm using windows 10 for it. MiA1 showing in device manager with yellow mark and when i manually install driver qpst manager detect com port but it shows No Phone on that port. what i cam do? or is it possible only on Stock Rom or is there different method to enable "HS-USB diagnostic" mode in LOS16.
and sorry for bad english pls. reply
Your custom rom doesn't have diag so that is reason why command doesn't work.
Here is supported Carrier Aggregation combos of A3: https://cacombos.com/device?model=M1906F9SH

I'm trying to connect to my device using QPST, but the device is not showing up in the COM ports. I've tried to delete all the usb devices related to the device in device manager but all to no avail. And none of the dial codes I'm using seem to be working. Only ones that work are those that start with "*#*#" and end with "#*#*". Only com port I get is the default COM1, to which there is no phone connected. The other problem is that the drivers I have doesnt seem to be working, I even had to install them by disabling hardware signing. Device is not detected in download or recovery mode either.
Processor is a MSM8212 and the mainboard is MSM8610.
I'm on windows 8.1
Your device is in regular mode... to access DM you HAVE to have it in DM mode.... so try EFSpro to switch your phone into DM mode or you will have to keep looking for a dial pad code. Some handsets allow sysfs to enable DM mode too. Have a look and do some research. Your QPST drivers should come from the manufacturer... ie I am using samsung drivers to use the DM port, not drivers from QPST.
Hello,
I would like to unlock Band 20 on my Tw Phone to be used in Europe.
THe Phone is successfully rooted and Superuser installed.
I have tried to connect my ZE520KL to PC with QPST and QXDM, because I would like to unlock the Band 20.
I have tried:
Device is rooted (follow this forum)
adb Shell / SU / setprop sys.usb.config diag,adb -> and confirmed the status is diag mode
Install Qualcomm USB driver (shown in Windows 10 Device Manager)
-> but QPST do not find any Phone or other USB device
Before this, I have also tried Signal Guru, which display Band 20, and I can lock it,
but the phone do not connect to any LTE band.
May I ask for any recommendations?
Is there any alternative way to unlock Band 20?
Thank you.
Take a look at this thread to start with.
I'm interested in this as well but haven't had any luck. From what I've read, it looks like its more than just nv values in 6828/6829 that block it from working, possibly hardware along with some other encrypted values that once you change seem to break all signal for the phone.
Hello, thankyou for the link.
I have tried it before without success.
Diag mode through adb works, but when i run the script to connect via the Qualcomm driver,
Adb closes (back to promt), but Qpst is still not finding any device.
Regarding Signal Guru: after root etc. I have installed signal guru, and the added Band 20, as it was not shown in original list. Now, when i lock phone to band 20 or lte only, the app tries to test but without any signal and then always immedeately switches to GSM back.
Any othe way i can try?

Hi Wang1Chung (Nihau
Did you try to install other custom rom, e.g. for Nougat (I am still using Marshmellow),
if this can help to solve to unlock Band 20?
I am still trying to connect my phone to QPST, one question here:
in the past, my Win10 Laptop detected the Zenfone3 as "other Device" and "USB Controller",
and today I installed one other driver (from Xiaomi Mi5) for Qualcomm, now the device manager
shows the phone at "Modems".
Does this mean, my Laptop sees the phone, and the driver works?
In this case I consider maybe by diag mode is not ok. -> How can I check diag mode is running?
I use ADB Shell with setprop, and in properties it shows "sys.usb.config diag,adb", therefore it should be in diag mode, right?
Is there any code I can put phone to diag mode (Just to verify it is not this issue)?
Thank you!
@Ser71MB1
I didn't try any other roms as there weren't many options when I tried.
I think Windows 10 is your issue. Try running Windows 7 32bit and force windows to use the driver that QPST can find that I mentioned in the previous thread. I think remember reading people had issues with getting QPST to work in windows 10.
From what I remember, with my phone plugged in to my computer, when I successfully enabled diag mode, my phone disconnected and then reconnected with a difference driver....is yours doing that?
Hi,
just tried for a whole day to enable the diag mode on the CAN-L11.
I have already rooted the phone sucessfully.
The adb command
Code:
setprop sys.usb.config diag,adb
isn't working.
Code:
getprop sys.usb.config
says the mode got activated but nothing is happening in my device manager and I have still MTP access on my phone.
Also tried it with accessing the "ProjectMenu--> Background Services--> USB Port Settings" way but there is only the "Manufacture Mode" available.
Does anyone know a way to access the diag mode on this phone?
Thanks for your help guys!
I wanna enable the diagnostic mode and try to see if i can add more LTE bands through QPST. I tried the generic command through adb shell and its not working Any suggestions are welcome.
Go to Emergency Mode
Type- *#3424#
This will enable diag mode.
Try thr Hardware test Mode
There is a way to enable the harware test mode on Asus zenfome Max pro M!.

Thanks but this did nothing for me. The phone has no SIM and the phone says emergency calls only. In the dialer though this code had no effect. the dialer just displayed it and sat there.
What am I missing? Thanks

Thanks for this. I looked at all the tests - which are cool. But I did not find any way to enter diag mode so I can try to use Qualcomm tools to unlock some more LTE bands. Am I missing something? Thanks
Iirc, a powered down (switched off) phone can be connected to PC with volume + and volume - buttons pressed simultaneously when connecting via USB to PC. Then PC device manager shows android device connected in diag mode (needs latest qualcomm drivers 2b installed in PC). I am not so sure whether windows need to be in test mode for this or not.

Thanks for this. I tried using both vol+ and vol- with power button. I get a completely black screen. But I do see some 9008 drivers get loaded in Device Manager. When I open QPST a com port is automatically found and it says that the device is in download mode. I cannot really do anything at this point. I want to start service programming so I can edit the NV using QXDM so I can add an LTE band. But this attempt fails due to download mode. I don't know if this is akin to the download mode I have seen in my Samsung phones when I use ODIN to flash firmware. The only way I have found out of the black screen is to press vol+ and power which eventually takes me to fastboot mode on the device and from here I can press/hold power to reboot to the Android system.
I am not sure I have the latest drivers. Now that I have the device rooted, I was able to issue "setprop sys.usb.config diag,adb" and actually see my Windows 10 computer show a diagnostics 9091 com12 port and a modem 9091 on com11. The driver info shown for this in Device Manager is 2.1.1.2 dated 3/19/2014. With this I can actually use QPST to read something from the device. But when I try to use QXDM to read item 06828 (LTE bands) I get "NV Status Error Received: Item Inactive". No idea what that means or what is wrong. Working on my old Samsung Note3 was pretty simple compared to this.
with root
enable diag port :
adb devices
adb shell
su
setprop sys.usb.config rndis,diag,adb

Guys, Any idea how to make these commands work on Android 11 ?
Both the codes do not trigger anything and does not show any new devices in device manager.
Hello friends.
I have spent 2 days reading the forums and finally decided to post after not being able to get my XT1687 to switch into DIAG mod so that I can use QPST.
The device is boot loader unlocked, flashed with TWRP, running Arrow OS Pie.
No trick such as using setprop sys.usb.DM or Diag, or anything seems to work. Also, no dialer codes seems to work.
All I can manage to do with Shell is reset the USB connection.
No combination of Vol + UP or 3 finger "saluting"... while in bootloader on BP Tools, QCOM, Tools Mode (Switch to Enable) seems to work. I have tried with every setting of USB Configuration combined with debugging on, or debugging off. Nothing will prompt my Windows 10 machine to call for several of the version of the Qualcomm driver's that I have installed - and the only remotely close to a COM Port is when I set it to USB Tether and sets up as a network adapter but I have not been able to manually update that or any other driver so that it establishes a COM port.
Like, am I just stupid and this doesn't have Qualcomm hardware in it or something?
Very much appreciate any guidance.
