Hi guys,
I own a Europe op2 and I'm going to the states on Friday for one year. So I saw this thread http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059 and tried to do it with my oneplus 2. So I tied EVERYTHING today but I just can't change my USB Settings. On cm13 it switches back to charging if I choose RNDIS and this guide http://forum.xda-developers.com/oneplus-one/general/guide-unlock-aditional-bands-qualcomm-t2877031 for the op1 tells me to use adb when on charging mode which is impossible for me. I would be really thankful if you could help me. Currently I'm back on OOS but I have nothing against changing my Rom.
So I just found out how to access diag mode with *#801# but QTPS and the device manager still don't detect my device
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!

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?
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
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.
Trying to enable 5g with QPST but as soon as I put my phone into engineering mode with *#801# I cannot install drivers it will not install anything I have tried three computers now with no change I've tried a bunch of diag drivers and I have the oneplus drivers installed and everything works as should aside from diag mode ???
Mod can delete I run 2 sim cards anyways always so
