Hi all!

I hope somebody knows the solution and help me.
I have four matching bin file from my original nand, but if i write it to my xbox360
( using nandpro 3.0 with nand x usb) the write process is successfull 100%
When i read back the nand from my xbox and comparing with the original correct nand, 74 non matching blocks found, every time (between 24 and 3FF). Possible to remap the 74 blocks? Or any other way to heal the bad area (ex. reflowing the nand) ?

My motherboard type is trinity in my slim xbox360 Error code :E79
Secondary error code :1033
Center led light

I tried to erase the nand before writing, check the soldering but nothing changed. Please help me if you can.

Thanks in advance!

Keep your NAND-x wiring away from anything which might cause interference. You're probably better to flash Xell and then use rawflash to apply your new NAND image.

My original nand dump is 100% perfect, without any bad blocks.
I check the wires with multimeter, all soldering contact perfect.

j2c1 pin 6 looks like a poor joint. prolly ok, just a thought. Martin would know much better than me, thats for sure

is your red wire actually in the hole, or on top of it?

ok - your red 3.3v wire is going to the wrong point completely. I suggest you STOP and look again at the documentation.

The amount of bare wire i can see very close to each other is setting off alarm bells. Why is it that alot of people leave the bare wire that long its just insane really. Have around 3mm of bare wire tin them and sink it in the holes your soldering to would look a lot cleaner mate.

Yep, this too - bare wire leads to interference, however in this instance the 3v wire going to the wrong point will cause problems.

Totally agree with you martin my comment wasn't really about the problem he is experiencing but i thought if he needs the soldering iron out to sort the 3.3v he could tidy up the install at the same time :)

Thank you my friends!

Probably my eyes was tired last night. I re-soldered the wires for coolrunner to good location, i power up, and i got the cpu key!
I go and finish my xbox completly, and i will post the results!

Thanks for all your help, but the problem not solved completly, i writed the nand with rawflash, but when i restart the consol with power button, the green led on the collrunner is blinking 5-6 times, the leds on the consol front are going to dancing glowing, and stop. Only the center green led light, and the red on the coolrunner.
