iPhone shut down, only powers on when connected to charger
I often do iPhone repairs but i have a question about an iPhone that is showing strange behaviour.
This iPhone 4 just goes black all of a suden. I doenst repond to anything, its not working at all at that moment. Also a reset is not possible at that time.
It is not possible to power on the iPhone. Only when connected to a charger is can go on. When its on everything is working fine, shows up in iTunes etc.
I replaced the battery with a new one a did a software recovery. Still the problems accur. It doesnt seem to matter if the phone is connected to a charging source or not, it just shuts off random. When the phone is on everything is working normally.
Another thing that i noticed, when its shuts down you wont see the spinning circle that you would see when manually powering off the iPhone, it just goes dead inmediatly. When the phone is powered off manually, it will also go on the normal way. When it shuts down itself this is not working
The battery is working fine, the phone accepts and charges it just like normal.
Home & sleep button are working perfect.
Any ideas what to do with this *****
The iPhone is now constantly fibrating, it was charging on my pc. Now it wont go on but keeps fibrating :S
When putting the iPhone in DFU mode and try to recover it gives errors. like '2005 and 106'
Any ideas? Any help would be apreciated
