"Unknown error (6)" with itunes, when restoring an iPhone 4 to 4.2.1 --what is this?

[thunderhawki]

Hello fam, I've been having this little issue for the past few days... I tried to update my already jb iPhone 4 (from 4.1) to 4.2.1 using iClarified's tutorial and have been getting a crazy error that doesn't seem to be an issue when googling. I don't really know what the issue is.

I checked the log and see that the TSS is started. I tried restoring while in DFU mode. I know that similar errors were with itunes not being updated, so I updated to the new itunes. I saw that some error codes where because for whatever reason, itunes had signed out--so I checked and resigned in just to be sure. Then I noticed that error code 6 a few years ago had to do with something in the host file, sooooo I went and removed those lines as advised-- but I still get the error code.

Now my phone is stuck in a recovery loop. I tried to use a saved 4.1 restore, and that still gives me the error.

Does anyone have any experience with this?

Edit: it was my attempt to update without upgrading my baseband --even tho the current baseband is unlockable. I didn't specify earlier that I do have the requisite SHSH files stored both with cydia and locally.

Thanks! I looked at the error code listings, and assuming that "unknown error (6)" is the same as error 6, then it isn't liking the USB port. Well, I tried changing to each of my 3 other usb ports (restarting after each change) and still getting the same error when restoring.

You may want to try another computer.

Just an update, you are amazing! Trying another computer did the trick!! I'm not real clear on why I needed another computer, tho. Any after I got the good error code (letting me know that the baseband wasn't updated), then I moved back to my computer and tried to move everything back.

Then I had a new problem. My device kept timing out when syncing the contact/pic/media/apps! I used WINscp to log into my i4 and remove the database files, which I read would resolve the issue, buuut no. So I'm now looking online some more before I bother this forum again just yet... :wink:
