Hello. Im new to the forums. I have an iphone 4 that was converted to white. it was working perfect before the conversion. A good friend of mine (he repairs iphones) did the conversion and said he used it for a bit after conversion. when i recieved it, it did not power on so i assumed it was battery. i took it home and no matter what i did, it would not power on. Only way it stays on is if plugged into power source. When i connect to pc all it does is show apple logo for about 10 secs then powers off. it will do this all day. As soon as its disconnected it will shut off. I can get it to be recognized by itunes and even put into dfu mode. but no matter what, itunes will not restore. I have also tried to jailbreak using redsnow and greenpoison. The whole computer process goes smooth but after it says done on pc, it continues for about 3 secs on iphone and it turns off completely and goes back to apple logo turning on and off repeatedly. I have tried alot of different things including doing official firmware restores as well as custom firmware restores. Can someone please help? Any comments are appreciated. Thanks. ***EDIT***.....so weird thing is when i plug into wall charger it will boot up normally, show the greenpoison logo and then go to the emergency call screen. But unfortunalety, as soon as i unplug it will shut off.
