Unsolved Jasper 0002 RROD after rgh 1.2 attempt

[cg6554]

Hello so I tried to rgh a jasper a few months ago but during it it got the 0002 error code it booted once but then it got 0002. I’m not sure what else to do I don’t know where/if there are fuses to check under the CPU. If anyone knows what could commonly die let me know. (Also I’ve flashed original nand back on with same thing) also it’s a Kronos 1 jasper so I don’t think the cpu would of died.

Based on the work of Octal450 seems like its a power related issue, "Replace Power Supply, Test and replace MOSFETs, caps, and controller chip on V_CPUCORE rail"

I’ve tried idk where the control chip is and I’m not sure what mosfets would short out? I suppose it would be the ones closest to the cpu. Do you know where the control chip is or what mosfets could of died?

Show your board, full pics top/bottom.
Power rail short is unrelated to the chip's wiring so you've messed up something somehow.

Kind Regards,
