if u really want to use the slow os 2.0, u could create custom firmware thru winpwn_2.0.0.3_setup.zip . choose the ipsw builder. u could download the readily available, iPhone1,1_2.0_5A347_Custom_Restore.ipsw thru torrent or http download.

if u want to go back to 1.1.4, read my other post. i got my iphone stuck since thursday, and only success after:
1. enter dfu mode
2. restore 1.1.4 factory firmware
3. downgrade baseband using "ziPhone patched by kIREmK
4. use ziphone to jailbreak & unlock

i got the original guide from neowin.net forum.

The thing is, iTunes 7.7 does not allow the restoring of the 1.1.4 and below firmares, unless of course your iTunes has been Pwned prior to the restore. For Windows users, restoring to 1.1.4 from 2.0 requires that you either completely uninstall iTunes 7.7 and reinstall iTunes 7.5, or first Pwning your iTunes 7.7 before attempting to perform the restore. wink.gif

*read my other post* or the original one at forum neowin.net

do not completely uninstall itunes and the other apple software component, just itunes, or u will end up getting exclamation mark for the usb device in device manager, and the device won't be recognized.

there are many video tutorial in youtube to address this problems, i watched the one that show, using iPod touch, and other tutorial how to enter dfu mode, etc.

after uninstall 7.7 do not forget to delete itunes folder in My Music (in My Documents)

Not necessarily, mate. wink.gif As long as you have iTunes 7.5 installed after that, the phone will automatically install its own DFU driver in Windows whether or not it's on 1.1.4 or 2.0, because all iTunes versions share and recognize the same DFU drivers. As long as there's the AppleMobileDevice.dll service running. The exclamation mark and USB driver errors only come because there's no service to recognize the device in DFU mode.

In other words, it's safe to completely uninstall every single speck of iTunes 7.7, but be sure to reinstall iTunes 7.5 and reboot before putting your phone into DFU mode  nod.gif

Quoted from Sleepers.net : Now that you have  iTunes 7.5, you will still have the DFU driver for 7.7.

The DFU driver is actually Apple Mobile Device Support, the 7.7 AMDS could recognized 1.1.4 and 2.0.

If u uninstall everything and install 7.5, you'll get AMDS that comes with 7.5. 7.5 AMDS could not recognized the 2.0.

Correct me if i am wrong.
