Hi, I have a iPhone 4S which has been water damaged. Had it in rice for two weeks, tried a restore all turned on back backlight wouldn't work found the screen and digitiser were damaged so I replaced it, and cleaned the mother board with isopropyl. I then fitted the phone back together and switched on, it all worked fine apart from cellular connection it just says searching. I then tried a restore, it's now back to factory setting and will not restore. Now the phone and iTunes says the phone is internally damaged. Can anyone help?? Note I lost the earth connection from under the battery clip is this important??
