I saw that before. It is the boy under the tree in main 608x800 resolution, displayed on a diags 600x800 screen. There are two known causes. Either your battery is not charged enough to finish booting into diags. Or your diags kernel does not match your diags partition version.
Charge it on a wall charger for a few hours, then use MfgTool to boot to fastboot mode and charge in attached to the computer for several more hours. If it does not boot diags to the menu, then use fastboot mode to flash matching versions of diags and diags kernel.
