Does anyone know how to enable diagnostic mode in the x10?
That is when android os creates a layer to the GSM modem chipset's USB from it's own USB.
Hello.
How can I connect my L9 p760 phone with Cyanogenmod installed to run adb? I tried reinstalling LGUnitedMobileDriver, PC suite etc, but nothing works. PC recognizes it as a portable device, but by installing LG drivers, I get error LGE U2 USB Device No driver found.
On stock rom there was option for USB connection "LG PC Suite mode" or something, it worked great with adb, fastboot. On CM there is no such option, just media and camera options, enabling debugging mode also does not make any change.
Why I need it, I need to log issues I have listed here forum.cyanogenmod.com/topic/80758-few-questions-regarding-usability-of-cm-screen-filter-lags-radio/
Maybe someone also had issue with freezes in interface responsiveness and/or call reject button and had those resolved?
Hi,
To solve LGE U2 USB Device driver not found:
- in Device Manager (are you using Windows, right?), go to "Computer/Manage/admin pswd/Device Manager"
- right click LGE U2 USB Device
- choose Update Driver
- now choose the second option (manual installation)
- choose in driver list: Android Sooner Single ADB Interface.
But... wait! One more annoyance. Your adb must be version 1.0.31 (requirement for Android 4.2.2 or higher), or you will receive error "device offline". To show yours, type > adb version
Awesome, works like charm. Thank yo so much!
WOW! Thank you so much. Now I can use my phone again.
For LG G2 D802 I found only the ADB method everywhere on the internet. There is also a method to properly enable the diag port on your G2.
First, you need to download the drivers from here: https://developer.qualcomm.com/download/iot/ioe-usb-drivers.zip
Then, dial 277634#*# > LTE-Only >LTE Data test > Tethering mode > QMICM
Windows will detect some unknown devices. Install the drivers manually from the location you downloaded them
This will enable the diag port to be automatically discovered by QPST, as opposed to the common method.
Happy hacking!
I need to open diag mode and using QPST, for using VoLTE in my country.
I found it can use *#*#13491*#*# code
then i selected
"DIAG,SERIAL_CDEV,RMNET,DPL,QDSS,ADB" and saw success message in phone.
but my computer couldn't recognize Qualcomm Port for using QPST.
In my computer's device manager, there is 5 devices detected.
COEV Serial
DPL Data
Mi A3
Mi A3(=>twice)
QDSS DATA
I already reinstalled usb driver(both adb and qualcomm), changed computer and USB cable, but same problem occured.
How can I use diag mode and QPST in Mi A3?
Is there any result? I'm waiting for an answer ???

Hello,
To open the Mi A3 diag port, just this code is not enough. You can open the diag port by following the steps below. If your goal is to change IMEI, this method can only change the SIM-1 imei number.
1- The "minimal_adb_fastboot" program is installed on the computer.
2- The phone is root by performing the operations specified in this link. (magisk.me/root-xiaomi-mi-a3/)
3- The phone connects to the computer and opens the diag port with the following adb commands.
adb shell
su
setprop sys.usb.config diag,adb
4- With the QPST program, the qcn file is taken from the phone. With QCN Tool, imei editing is done. and with QPST is restored to the phone.
Thanks Kingsman :good:
hi everyone when i open my diag port via adb i can see the diag mode on computer connected normally but qpst even if it finds the diag port correctly couldn get phone information, phone shows as unknown so qcn backup gives error can anybody help?
Hello.
I have tried to get usb debugging popup enable via various tools in windows. For example when I have recovery my phone, i enter welcome screen in setup wizard, press on emergency button and then i type *#0*#, and then the windows tool can open usb debugging dialog, how could this be done manually since im on linux i wanna know how this is done? Do they use an AT command in /dev/ttyACM0 for get this debug popup to show up or how is this done?
As in the first example on this post: https://www.techeligible.com/2022/05/18/top-ways-to-bypass-frp-galaxy-s7-edge-android-8-7-6-updated/
How can this be done from command line in linux?
It works on both phone and tab it seems from s7 model
Cheers
