JTAG NAND X E79 Tried everything!

Ok cheers man, I will try resoldering all tomorrow, maybe even with just good old fashion wires

I desoldered all the QSBs. Since I only have one pin header (I lost the other :/), I pulled out individual pins out of the pin header and soldered the pins to the mobo and used the pin header cable to read to nand. I read the nand twice and compared and had 0 non-matching blocks (I will post pictures later as I am busy atm).

So it must have been my soldering like Martin C was saying. Therefore I will resolder and replace all the parts in the jtag/smc part. Will these 1N4148 diodes work for this?:

If this doesn't work would you recommend wiring 3 330ohm resistors instead? Thanks.

Cool - at least you're getting somewhere now.

1N4148 will work fine. Don't go for resistors

I can't get the diodes for a couple of days, so I tried the three resistors as I thought it was worth a shot. Like you said it didn't work; I got the E79 error again :/. Oh well il just wait till I get the new diodes. Also I decided to use the pins from the pin header to solder the resistors to, since the pins seem to make a very good connection with the mobo. Cheers
