Thanks for the images for the nand points dicko.
I finally got it to write on nand!
Problem was, when i flowed on the spare part nand there had been couple pins unsoldered. Only touching the pads. And i thought they were good, since when i tested the points with my mm, i put the probe on the pad, not the leg of the chip...
Anyways, it actually boots now! But theres another problem, after writing stock nand there is rrod 0022 after about 30 seconds of booting.
I also tried installing the coolrunner back and created the .ecc and it will boot Xell fine. But when i created the freeboot image and wrote it with rawflash, when i boot it just stops glitching after couple of cycles and stays there.
If i boot with eject, again it boots Xell with no problems.
So could this actually be a rrod issue at the same time caused by poor connection of GPU or HANA?
I dont wanna lose hope with this one just yet, since i made some progress with it..
