RGH Really weird falcon problem

[zackf89]

got this console came in with e71 failed update....RGH'd it and repair'd nand and was getting it to boot first time EVERY time and then it just stopped glitching.

Fans reset 1-3 times a second and coolrunner ONLY slightly blinks first time unless i push down on the mobo near the memory cards. Holding that down and it will boot fine. If i press down anywhere else or on any chips it doesnt help.

Ive tried:
different nands
different wiring routes
shielding post_out with tinfoil + etape surrounding it
shieleded wire on CPU_RST

no matter what the ONLY way it will boot is if i hold down the board near the memory slots. It will continue booting fine unless i remove the pressure and then it will freeze.

When i hold it down the coolrunner and fans go back to normal (resseting when the SMC resets) (blinking ONCE every few seconds).

Ill upload a vid in a bit but i cannot seem to figure this out i've done tons of RGH's

Edit: could it be the wiring of post_out? should i try double loss 50ohm cable or w/e its called from xconsoles on Post_out?

Check your soldering on the yellow wire.

no way ive tried 3 different wires using different routes each time and my soldering is good on the points....no pillowing all the solder is one continous blob

Get some pics up m8, need them for proper support

videos uploading now. Not sure what pics would do considering my soldering is perfectly fine (not to be rude) ive done 30+ jtags and 15+ rgh's im not some monkey with a soldering iron

Well not to be rude but it's a requirement if you're wanting help.

If your console boots ok with the retail NAND without any wiring in place, it's 100% your soldering/wiring.

ok ill get some up when im at home. The problem is i dont have a retail nand because the console is a failded update broken xbox. Its freezes @ the bootscreen b/c dashanim.xex or xam.xex or something else was corrupt (bad blocks etc). so i used a donar nand to build a xebuild image that worked fine until it randomly stopped glitching.

If you can get the CPU key, nothing stops you from building a retail NAND. Try this first to eliminate everything else.

route cpu rst wire on top of the board near fans place.
desolder cpu pll bypass wire.
