By mistake I upgraded my OTB unactivated iphone to 1.1.3 and now itunes 7.6 wont let me downgrade to any earlier software and also my turbosim arrived shortly after I changed to 1.1.3 so I am stuck.

I have looked at the below tutorial for downgrading from 1.1.3 to 1.1.1 (below) so I uninstalled itunes 7.6 and installed itunes 7.5 as in the tutorial.

1. Connect iPhone with PC
2. Download iPhuc http://rapid$hare.com/files/84214672/iPhuc.zip
3. Unpack & start iPhuc.exe
4. Type in "enterrecovery" and wait until iPhone enters Recoverymode (Notice be sure you are on iTunes 7.5 and its running while doing this tut!)
5. iPhuc window should say: <iPHUC Restore> #:
(If not, restart iphuc.exe)
6. Type in "filecopytophone WTF.s5l8900xall.RELEASE.dfu"
7. Type "cmd go"
8. Wait until iPhone Screen turns white and iTunes recognizes a device connected to it
9. Hold down shift + restore -> choose FW 1.1.2 -> let it finish -> do the same and choose 1.1.1 fw
10. Use iBrickr to kick the phone out of the DFU and go on as usual

When I type in enterrecovery into iphuc the bottom line comes up as <iphuc recovery> #: which is not as described in the tutorial and if I continue entering steps 6 and 7 it does nothing.

Please could somebody help.
