Hello, I received this phone with water damage.

-It is only powered on if connected via the USB.

-If connected to iTunes is recognized as needs to be restored.

-It displays the screen that has the USB connector and the iTunes logo.

-When I try to restore, after extracting software etc it says Error 21.

Any ideas ?

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 want..ie if you need an unlock then don't update to iOS 5.

I'm not a Jb guru but plenty of sites like redmondpie.com 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
