This is most likely a jailbroken phone, apple won't let you restore the custom firmware. Do a quick google of error 21 and there are lots of answers. If you are familiar with jailbreak then you just have to "point" to the firmware you want.It all depends on what firmware/baseband you if you need an unlock then don't update to iOS 5.

I'm not a Jb guru but plenty of sites like have good tuts on getting you started.

Thanks will try it. I was worried that was a hardware problem since it doesn't charge. Even though most likely I'll have to change the dockl connector I think


Gustavo Camacho, you definitely want to change the battery. You mentioned that your phone only turn on when connected via USB, sounds like a bad battery....:-)


oldturkey03, do you think it could be the dock connector as well?


I'd follow the advice of my colleague pollytintop first, after replacing the battery. You also want to clean the phone properly of all corrosion, since it was water damaged. At this time, the dock connector would be low on my priority list.


Thank you oldturkey03
