[Q] I Screwed Something Up
A friend of mine had a Galaxy S3 Amber with a broken (and blank) screen and wanted her data from it's internal memory that is locked and not in debugged mode. I did a lot of research and found the best, most efficient way was to do a motherboard swap with another gs3. I had a Galaxy S3 Blue. I watched a couple of videos and it seemed rather easy. I gathered the proper tools and was EXTREMELY careful not to break or rip anything (and to my knowledge i did not). When i put her motherboard from the amber one into the blue one and the screen would not come on. My first thoughts were it must be her motherboard that went bad. Well when i went to put my blue gs3 back together (again being very careful this entire time) I'm now having the same issue as she was. Black screen, no back light. The bottom lights DO come on and i feel it vibrate when i get a message. There was also no power on chime...
I know its hard to tell with out looking but any ideas on what could be wrong or what i might have screwed up? i checked all the connections and everything looks perfect. Nothing is bent or connected wrong and I didn't force or break anything.
update: so i found that the touch part of it still works fine. i can hear the ripple unlock as well as all the other sounds and such when i touch around and i can here it opening apps. the only issue lies in the screen itself being blank with no back light what so ever,
