RGH corona v2

[davyboy]

Hi
First off like to thank everyone for this great forum.
Now for the problem, I obtained a corona v2 with the wrong dvd drive fitted, I had a coolrunner lite sat here which I fitted after reading nand and saving it to a safe place. after programing cr3 and writing ecc the cool runner dbg would not flash no matter what settings, as the cr3 had been sat here I while I wondered why I had not used it, faulty maybe. Removed cr3 reflashed nand and console booted. I then found a stockist of the proto chip ( v1) which arrived in 2 days .
Fitted this but did direct wire to bottom of board as I only want keys. flashed premade ecc to nand and tried to boot, no matter what dips all I could get was intermittent green light and the odd fan increase, so check soldering, no visable faults , tried this several times to no avail. So I reflash original nand disconnect proto and remove from system. On booting I get green power light on front console(no dancing as blakey would put it) which then turns straight to solid red
but it stills boots to dash. I have checked cpu- rst and post points under micro-scope but they look ok. Failing cgpu hence the odd flashing green dbg light ???

thanks for advice in advance

i first tried coolrunner then proto neither are now installed, original nanddump reflashed console boots but gives red dot on front but still works ok

your problem es not with the chip Ive seen this problem some were else,, from another member on another site
had the same problem there was no wire or chip problem,,
his problem was the Xebuild.
that was causing red dot.. trying getting the latest JP version.
fresh download, End trying remaking the Xebuild nand.

As no glitch chip or wiring is now installed and original nand has been reflashed I don't believe Xebuild comes into the problem.
