Same problem over here... upgraded firmware 3.0... i was listening music and the ipod just forze... now it is in DFU mode... and Itunes wont restore it due to the error 28..

APPLE STAFF MAKE SOMETHING... this is not a HW problem... obviously this is a malfunction of the firmware... and why you put number to the errors.. if we all have error 28... then you must know what error 28 is...

Sorry about my english :S...

Have a 3g with 3.0. Brand new phone - just replaced by Apple Genius on July 11, 2009. Have been in Boston this week and have been attempting to recover from the "black out" persistent "connect to iTunes" image as the only thing on my iPhone. Same attempt to restore and receiving the error 28 just like everyone else on this thread. I must say, I am horrified that Apple is hosting this discussion thread and has yet to respond to any of the many requests for help. I believe in Apple and their service, but how can we be sure they even look at this stuff?

From what I can tell, no one has come across an answer yet - not even Apple. Given that my 3GS is operating in stellar fashion, I would argue that 3.0 has overrun the 3G hardware, or that Apple has turned out an enormous batch of bad 3G phones that need replacing. I'll be going to the Apple store when I get home on Sunday, and get this 3G replaced. And I will find out why Apple is not responding to our pleas for help, and then post what I learn.

I bought an iPhone 3G 8GB from Orange this past wednesday, same day i upgraded to version 3.0, the next day, as i was listening to some music, it just froze, and the "iTunes" screen came on.

I tried connecting it and it states that iPhone is in recovery mode and needs to be restored, whenever i click on restore, and as it says "Waiting for iPhone", it gives me the Error 28 message, i tried to:

install latest version of iTunes.
Restart my mac and try again.
Restore iPhone from another PC.
Create a new Admin account and restore from there.

NOTHING WORKED. i went to Orange on thursday, and they said they will check it and get back to me, this is ******** that apple is not acknowledging the problem: i have everything as it is in the book: Locked iPhone to Orange With Contract... FIX THIS.

I have the same problem with my original 2G iPhone. The phone shows the "plug me in to itunes" screen. When I plug it , iTunes says it has detected a phone in restore mode. When I try to restore, it get error 28.

I called Apple Tech Support and their only solution was to take it to repair center or pay $199 for a replacement.

I've tried restoring from 2 different PCs, about 50 times!

When it first happened, I was able to restore, but within about 30 minutes, the iPhone went into and reboot loop and hasn't worked since.

Ugh!

I have the exact same problem. I have tried different itunes versions, different firmwares, different iphone cords, different computers (vista, xp, and a macbook pro) and nothing will restore. Put the phone in DFU mode and attempted to restore about a thousand times over the last week. The phone is only about 6 weeks old and happened about a week after I upgrade the firmware to 3.0 Has anyone been able to restore after an error 28?

seems to me, that this problem is still unsolved an that apple overestimated the power of old iphones. therefore they burn with OS 3.0 and you will receive an error 28.
I have tried several options (5 different pcs (from xp to vista64); 3 different macs (macbook, macbook pro)), all versions of itunes 8, reinstall, restart, dfu-restore, nothing worked!!!!!
best is, to bring all the iphones back to apple and they have to handle the problem. if anyone finds out different solution, please let me know

Hey guys,


After about 6 hours troubleshooting with apple and rogers.. i decided to take matters into my own hands. This is what worked for me. First off this issue is a firmware problem and is temperamental which means it will go away when it feels like it. If you turn your phone off and let it charge over night. Don't touch it till the next morning after its fully charged, Turn it on the next morning and try and restore the phone. You should be able to do it without getting error 28 or sometimes 9. If you do try it again in a different usb port and restart your computer. if successful turn your phone off and on then do a reset network settings after that do a hard reset ( hold home key and power button) after it turns back on restore the phone and update (don't update to verson 3.2) you can backdate your phone to your previous setting. Hopefully this works for you guys.
