Re: sorry, probably a dumb question
Why did you fsck with it if you don't understand what you're doing?
My guess is you borked the downgrade. Are you trying to upgrade from Mac or PC? Try putting it in DFU mode, and restoring the desired firmware, from a NEW user account on your Mac/PC. DFU mode: http://iphoneindia.gyanin.com/2009/1...toring-iphone/ The "fix" for error 21 http://forums.macrumors.com/showthread.php?t=975858 http://discussions.apple.com/thread....ageID=11723151 Here let me google that for you: http://www.google.com/search?q=iphon...pdate+error+21

Re: sorry, probably a dumb question
I'm on a pc. Thanks for the info. I'm pretty sure i did the downgrade correctly. I followed the instructions for that exact and used recboot to get past the 1015 error code. That all worked fine other than redsn0w not working to jailbreak. But jailbreakme.com worked great so not a big deal, I guess.
I searched all over google for error 21 and all I came up with was the stupid apple help page suggesting antivirus which is obviously not the problem and threads where ppl asked the same question but got no replies. Guess I didn't look deep enough. I usually give up after I go through more than 5 or 6 pages of google and don't find what I'm looking for. I'm not new to messing with smartphones, just new to iPhones. Last edited by Squirrel240sx; 09-04-2010 at 01:09 PM. |
