ANSWERED Xbox360 not booting after JTAG!!

[IRAQI HERO]

Hi,

After soldering and connecting the cool-runner and all wire and using Jtag Tool to read nand1&2 and compare between them and creating ECC. Then i have to get the CPU Key when the consol boot but the problem is the consol not booting and the green light on the cool-runner flahses many times.

I check many threats on site they mentioned the space between wires but still not working.

Can you help me PLEASE.

Regards,

Ollie

can you provide pictures of all your soldering. They need to be good quality and in focus.

You did program the ecc to the nand right.

Which xbox
Which Motherboard
Hi res pics of your soldering.
It is normally a STD_CLK soldering issue if xell is not booting (Using the eject button only)

 

[IRAQI HERO]

Thank you for response. Find below the required picuters:

 

[Goldensavage]

silly question, you are pressing the eject button to get xell up and not the power on button.

Also you didn't mention programming the coolrunner with the correct file. I assume it's a jasper as you have already applied the caP

 

[IRAQI HERO]

No, i am powering it by power button.

Yes, it's jasper 512 but i hqave same issue on Xbox360 Slim!!

I don't any problem with programming cool-runner.

try flashing back your org nand and see if the console then will boot

You mean "Write ECC.)?

 

[Hackerjac]

no i mean write the nanddump you read out before making the ecc

 

[frazzeld]

Is your red wire going to the correct point I cant quite make out with the photo angle

 

[mausyui]

to get into xell (and get cpu key) power it from "eject buttton" .

 

[Goldensavage]

To boot xell, you must boot with the eject button. The power button will not boot the 360 because the ECC has been programmed on it.

The coolrunner interrupts the processor allowing the ECC to run, but only when the eject button is pressed

I think he meant original nand.

In the post you said you created the ecc but you didnt say if u wrote it..

 

[IRAQI HERO]

Yes, it's in the middle.

 

[Goldensavage]

Press the eject button. Not power.

To boot xell, you must boot with the eject button. The power button will not boot the 360 because the ECC has been programmed on it.

when i have flashed the ecc (50 block) to get the cpukey it dosen't matter if i use eject or power button, it load xell reloaded anyway

 

[IRAQI HERO]

I power it up by Eject button but still not working!!

What you mean by writting the original nand? I just read nand 1 and 2 then compare the read ECC then wrtie ECC.

Thant you all for help.

 

[Hackerjac]

i hope you have saved nand 1 and 2, if so, then write nand 1 to your box and see if it then will boot

 

[gerardo15]

Original nand its 1 of those 2 files that you read any of those two will work

 

[IRAQI HERO]

Yes, i have saved nand 1 and 2 and when i write back nand 1 to the xbox360 works fine. But i want to know why is not booting when the cool-runner is connected to get the CPU Key!!
