Info is needed to work with, bootloader version, s-on or s-off, what did he do to get stuck on the boot screen?

Factory resetting doesn't cause a phone to bootloop or get softbricked, just saying.

Anyways, if you have a custom recovery installed, you could just simply wipe the device and reinstall whatever rom it was.

To go back to complete stock, look for the most recent GB stock ruu file in the dev forum, download it and place it on your sd card. Rename that file PH85IMG, reboot into bootloader, follow all on screen instructions to restore to stock. If the device is s-on, you will need to lock the bootloader before placing that PH85IMG on the sd card.

Or you can look for the most recent ICS leaked ruu zip file to go straight to ICS instead of GB, instructions to use this file remains the same as GB.
