iPhone 4s won't charge or restore
I'm trying to fix an iPhone 4s for my mother. She's elderly and only understands this phone.
Her husband dropped it in water. I dried and cleaned it well. I replaced the battery as well. It will go to recovery mode and DFU. Though it will not charge, even with the new battery and even though iTunes does recognize it. It throws out an error 21 when its trying to restore.
I am all out of ideas and can't afford to replace it for her. Any help would be greatly appreciated!! Thanks.
Is this a good question?
