3.0 Beta 2 and Recovery Mode

Tried upgrading to Beta 2 and got Error 1602, log below:

Accepted the forced restore to 2.2.1 and got Error 1604, log attached as iPhoneUpdater 2.txt.

After that, I twice attempted deleting the 2.2.1 .ipsw from C:\Documents and Settings\Username\Application Data\Apple Computer\iTunes\iPhone Software Updates while switching out USB ports to the other two on my laptop and twice got the same error, attached as 3 and 4.

Any ideas before I hit the store tomorrow? Thanks very much.

(For what it's worth, my initial upgrade to 3.0 Beta 1 didn't go smoothly either, and the log for that is attached as iPhoneUpdater.txt).

 

No, and I've never needed to do it previously so I'm not sure how it works - are these instructions accurate? Thanks.

1.) First download the required archive http://www.sendspace.com/file/93fx93 (DFU.zip)
2.) Extract the archive to the root of your hard drive, should be C:/DFU/
3.) Connect your iPhone and ignore iTunes
4.) Goto Start - run
5.) Next type in “c:/dfu/dfu iBSS.m68ap.RELEASE.dfu”
6.) Wait for iPhone to show a “white” screen
7.) Now you may proceed to downgrade!

 

Thanks, will do. One last question before I try - is there any way to use DFU mode to restore directly to the new 3.0 build rather than go back to 2.2.1?

 

Thanks to both of you - DFU did the trick. And yes, I could indeed Shift-click to choose which .ipsw to install out of DFU - not sure if it wasn't possible in recovery mode or if I didn't try it properly, but thanks for the suggestion

Kman, I was going from Beta 1 to Beta 2 - I'm inclined to believe it was a hardware failure on my laptop's part, my USB ports haven't run at 100% in a long time.
