Powers up with apple logo, then screen goes black. Itunes sees it.
This was a water damaged phone that was given to me by my friend. After watching some youtube videos and guides, I have replaced the charging port circuit and the battery. Everything else on the motherboard looks clean.
When powered on, the apple logo comes up then quickly disappears. Itunes will detect the phone. I get the messages " Do you want to allow this computer to access..". I can pick Continue or cancel. Howerver if I continue it tells me to do what it asks me to do on the iphone however the iphone screen is black.
I have not been able to get into Recovery or DFU mode. Every time I try I keep getting to the "" Do you want to allow this computer to access.."" question rather than recovery mode or DFU mode.
Any ideas would be much appreciated.
Thanks.
