[1.1.2 OTB] - Hardware unlock - ieraser can't write

Hi, i have searched through all the threads for hours and can't find the answer to my problem, can any one try and help!

Basically i have followed the guide to hardware unlock at http://iphone.unlock.no.
I installed the relevent installer packages and started terminal!

i typed in :
launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist
cd /usr/bin/
ienew

it says:

Resetting the baseband...Done
Opened: /dev/tty.baseband
iEraser for 112OTB: tool by geohot
Waiting for data..
Can't write

Iv repeated this hundereds of times and nothing has worked, also i have restarted the phone and the problem still occurs!

Any help please??

i have tried following steps of many guides and no luck!

have you ever tried to restore your iphone to 113?

What firmware do you have now? Did you install terminal?

Instead of launchctl unload /System/Lib...
try this: launchctl unload -w /System/...

yes i preformed all the steps on terminal!

i have firware 1.1.1

yeh thanks tried that but makes no difference!

any other help would be greatly appreciated!!

Did you chmod all the files?
