i was doing a jtag in may box, i dump my nand 4x and match, but when i flash it xbr3 it give a e79 error, then flash it with my backup and it boot fine, then i try to flash xell it wont boot, then i flash my backup again it wont boot ether it give a 0022 error?

plese help i don't know what to do next.

i'm using usb flasher

Nah, its not dead. Did you inject your keyvault? Any bad blocks when you dumped?

probably just a bad flash.erase the nand then re-write it

what will happen if i dont short the pin 4 & 7 in jtag wire, and i dump it, then write the nand?

Those pins have no bearing on flashing or dumping the nand. They are only needed in order to boot with a patched nand.

Check your jtag wires/diodes. Try alternate points.

resolder all of your jtag wires and maybe use some other diodes.
When even xell is not booting it just might be bad wiring.

You're either having:

1. Read/write issues - try writing to the NAND, then read back what you've written and file compare the two.

2. Your wiring is bad - test your soldering with a multi-meter. Also check the mobo and if you have any canned air/ iso alcohol give the BGA area under the GPU a good clean.

3. There's a possiblility your NAND is 'stuck', point 1. above should answer this.

What tutorial are you suing for the 3 jtag wire points?

i use this for reference in my jtag wiring

and i even use the alternate points

And you have the diodes facing the proper direction?

Check for ground shorts on the J1D2? (at work at the mo so can't remember if that's the right one - basically the jumpers on the mobo that you hook up your USB flasher to) - I've seen a couple of 360's where something's gone horribly wrong and the pads (other than the ground one .5) have a short to ground with resistance.

Maybe try the SMC patch and alternate points?
