Does the bootloop and motherboard has any correlation?

I bought oneplus one 64G phone on Jan 2015, I didn't have any issues with the phone. No games or any other hardware intensive app with my device. On a day, when I opened my uber app and turned on GPS, phone went to bootloop. I formated it, cleaned my OS via fastboot and adb mode (several images which are part of oneplus one), nothing worked. Seeked oneplus one remote assitance, not able to identify and asked to visit ESC (excl. service center), they told motherboard issue, as their software isn't flashing my device. I told them I able to flash various recovery images (twrp, cyngn recovery img, cwm) but not actual OS. Is it directly related to motherboard or it is a wild guess.
