[One (M7) Q&A, Help & Troubleshooting] ayyu3m:
[MENTION=2605798]nkk71[/MENTION] I tried as per your instructions and no luck in fetching the logs.

When i did a factory reset from the bootloader menu, the device restarted to Google logo splash, stayed on it for abt 3 minutes, rebooted twice again to Google logo and then started the boot animation and switched off after 3-5 secs.

After that i switched the device ON again while connected to PC and had the adb command running but it just stayed at <waiting for device> as the phone went into Google logo splash boot loop and never actually made it to the OS or nearer as evident from Windows trying to install HTC MTP Device resulting each time with Failed as in screenshot.

Here is the cmd promp output with the adb command last.
