Hello guys, i have a problem when i use my iphone and suddenly goes dead after i opening games. I tried to restore with itunes and the result is nothing with 40 error and in next day i tried to dissambly my iphone, it turn out the battery slot is detached. ‘‘‘The question is, it’s possible to restore without the battery and is my problem on the battery or ic power ? Because when i attach my iphone battery again and start restoring again, but the result is still error 40. ’’’ By the way, when i plug the iphone to my laptop, my iphone just not showing sign of life ( just black look like the lcd not turn on ) i keep tried to restore, but on “waiting for iphone” process, my iphone showing apple logo with loading animation, after the apple loading animation show off on my iphone, i get error 40 on the itunes.
