[Pixel5][DIAG port] How to open DIAG port on Pixel5 to connect to QXDM/QPST

[asharz]

Hello all, I read through some old Pixel forums on how this was achieved on older Pixels. This is what I have tried so far, but all in vain.

Pixel5 (Build: RD1A.200810.022.A4)

1. I have unlocked Pixel5 (USA) bought directly from Google. I extracted boot.img and patched with Magisk to gain root access. Once rooted, I tried "setprop sys.usb.config diag,usb" but didn't see any impact on ports.

2. Found out that I will need userdebug vendor.img from https://developers.google.com/android/drivers for my build. I extracted it and flashed it "adb reboot fastboot" & "fastboot flash vendor vendor.img". Once did this, the phone gets stuck in bootloop.

3. I used factory images from https://developers.google.com/android/images for the above build and did "flash_all.bat". Phone came up fine with stock image and lost root access. Tried to flash the same vendor.img in fastbootd mode, and again got bricked. "your device is corrupted and cannot be trusted" and stuck in bootloop.

4. Restored the device again with factory image "flash_all.bat".

I need to access the QPST/QXDM ports on this phone. I have found most my answers on xda forums and was wondering if someone ran into these issues with Pixel5.

@Obeid Allah How do I revert my phone back to the original state it was in before issuing the adb shell commands?


I figured it out and it worked

You need to open cmd in the same directory as the adb tools folder.
You can download adb tools here: https://developer.android.com/studio/releases/platform-tools.
Check regularly to make sure your adb tools are up to date.
