Before i desolder everything again i decided to inspect the whole board for bridges.
I find a resistor that was bridged, probably soldering or desoldering something some solder flew away :s
so i fixed it and flash retail nand. First from 0 - 50 then the complete nand unmapped and remapped.
The result was the same everytime. No rrod. No image. Just the center light blinking (dvd off) and that was it.
Then i thought, maybe it's something in nand that won't compromise the ecc. maybe it wouldn't glitch because of the bridged resistor but now it will. Flashed ecc again, soldered CR again, but it won't glitch. Same thing. green Flash once, fans do not reset. No RROD.
I believe the rrod has gone. It was caused by the bridged resistor
