CORONA Corona 4GB XBOX360E red dot

[WalangAlam]

Got an xbox360E rghd last Dec2014. My friend said he was playing and experienced a fatal crash and it won't boot anymore. Reflashed the orig updflash but no boot. Reflashed the original nand dump with all the wires desoldered and got a red dot. Once it booted to the xbox logo but the logo was checkered and stop there. Is there any way to fix this? Maybe corrupted 4GB? no way to bypass the 4GB or disable it in RGH?

is there a secondary error code, it being a red dot or having checkered logo on boot I would guess that it maybe a gpu problem, and it may need a reflow

This happened on a Trinity of mine.
It sounds super simple but, I resolved it by ensuring that the x-clamp was secure and the screws holding the motherboard to the metal chassis were also secure.
