FIRST
Go to MEMORY ON YOUR XBOX
Than go to GAMES
Than find BLACKOPS: CLICK ON IT
THERE you will see TITLE 3 UPDATE:when you find that hit X OR Y but delete it
Than go to your Computor and put gpd on your hardrive
as soon as you get to your xbox sign out of account
than go to ZOMBIES and SOLO and your good to go

Jman3350 wrote ok so when i replace the 41560855.gpd, everything works fine. but when i move it to my xbox, it says profile corrupt. what am i doing wrong? (by the way i am trying to mod black ops offline zombies because i don't think you can do online anymore without a JTAG.)

rehash and resign

ye does work without a jatag im in it right now your forgetting to rehash and resing if your still carnt do it go to this form Forums/viewtopic/t=683685.html
its not mine but that is where i learnt to do it just read the tut

i do rehasn and resign. maybe its because i'm using modio? and i did have the title update deleted

I forgot what you also need to do is go into network and press y to disconnect don't remove the wireless think

yeah i am signed out of the network. it still says corrupted profile! i have a back up profile but what the hell am i doing wrong?

this has happened to me many times and theres nothing you can do about it

just do it with a different profile,
make a account with xbox live silver.
get an achievement in black ops (standing up in the chair) that will create the black ops gpd

do the same thing youve been doing and it should work,
ive curupted 2 profile but incase this happens i recoment copying your fresh profile before you mod it so if you mess up you have your profile again.

I've had this problem; my way to get around it is simple....

Make sure TU3 Is Deleted
Clear your system cache
Move your profile to usb (if you haven't already)
Dashboard.
Remove usb.
Modio --> Replace .gpd
Rehash and Resign.
SAVE TO DEVICE
Rehash and resign (i'm not sure whether this bit matters)
Remove usb
re-insert into xbox360


(IF YOU GET A PROBLEM WHEREBY WHEN YOU BOOT BLACK OPS IT BOOTS TO THE MULTIPLAYER MENU... you need to edit your profile in xero and makesure that you have mp_start"0" and not "1")

PM me if you need anymore help
