hello, I did the jtag hack using the lpt method on my falcon 5771 by followed this guide http://docs.google.c...mv5h_186pp2zddm

I've added the 100omh resistors and diodes.

There was no problem on the FC comparison of the First 2MB of NAND, Key Vault and the Config dumps

so I Inject Key Vault into free60.bin then Inject XeLLous into Free60 all OK

then Flashed free60.bin to  XBOX.

nandpro lpt: -w16 free60.bin 0
Testing LPT device address:0378
FlashConfig:01198010
Using LPT device at address:0378
Starting Block:0x000000
Ending   Block:0x0003FF
Writing
File: free60.bin FileLen:14a000 Block:50
004F

and that was it, not sure if it was supposed to stop at 004F , should it have stopped at 3FF??
now when I power on the xbox with network cable connected and powered using wired controller from front usb port, there is no response on the screen, not even a blank screen, after a few seconds I get 3RROD???
I have tried to put a 470omh resistor on the jumper as instructed on this following still no joy

hope someone can help. sad.gif


did you install the jtag wires correctly? yes its suppose to stop at 4f. Are you using the correct free60 file?

not sure, on the guide it said  2. Now search in hex for "CB" (without quotes) your looking for the one at or around 8400 in hex (it has to be in caps).

The 4 Hex digits after CB I got when converted hex to dec gave a 5 digit finger, so I decided to do a CB search in the text then copy the 4 Hex digits of that after CB and when converted, that gave me 5771 so I used falcon_hack_updxell renamed to free60.bin, is this ok, was I supposed to do a search in hex for "CB" (without quotes) or a search in the text/word for "CB" (without quotes)???

its a 175 PSU Hdmi 360

thanks please do let me know

check your cb using the new images in my freboot tutorial in my signature report back, and private message if you are still having problems.

there you go. Also 5771 is not exploitable if it is a falcon. You said hdmi and 175w power supply right? If so then there is a good chance your xbox is a falcon which mean 5771 is not exploitable.

You can't reverse it an Efuse blew that locked out the kernel required to run the hack. Sorry man looks like your out of luck.

to revert just flash back the 2mbs and undo all your soldering and wiring you applied.
