I messed up my Falcon that i was trying to jtag a while back.
I did the bad smc flash, and that didnt work. Nandpro just kept giving me errors.
Anyway I took a scrap xenon, and flashed the original falcon dump to it and then desoldered the chip and soldered it onto the falcon board. But it wouldnt boot up. So im just wondering why it didnt work. My guess is that my original nand dump had some is missing some crucial data (it did have some bad blocks).
I dont really care much anymore since i have a jtagged jasper, but i would like to know why it didnt work.
Might as well learn something from it.

Did I read this right?
You took a xenon cpu and reballed it on a falcon board and wondering why it didn't boot?

No, just the Nand Chip.
i was looking but couldnt find anything that said the nand chips were different. I have another rrod falcon but its pre-nxe so you can see why i didnt use that one.
Here's what i did.
Hooked up flasher to xenon board
Flashed Falcon nand to xenon board
Desoldered xenon nand and put it onto falcon board.

Are you desoldering the nand flasher or the whole nand chip?
If its the whole chip, you would need to change the CPU as well

The whole nand chip, I know that the nand and cpu must match.
Xbox 1 = bad flashed
xbox 2 = scrap xenon
If i take my nand dump from xbox 1 and flash it to xbox 2's nand, then take the nand chip off xbox 2 and put it on xbox 1, theoretically should work. (Unless the nand chips are different on the different boards). I know the SMC and all that is different, but im not using a xenon image on the falcon, i just flashed the falcon image to the xenon chip, and took that chip and put it onto the falcon board.
I never was able to get power to to the falcon after i flashed the bad freeboot image. Thats why i attempted this. I realized i screwed up the falcon a long time ago so im just messing around with my scrap boards.
