Chosen Solution

Hi, My iPhone has no previous backup and while it was on charge yesterday(the battery was flat), the Samsung adopter exploded. Its charging port was now not working. I tried to put the motherboard into another phone and it nows displays the screen but the apple sign stays on like for a minute and it restarts again to show the same thing again. Is there any way i can fix that without loosing my data? Thanks a lot..

This sounds like you have damaged one of your charging IC’s when the charger failed. This is quite common and can easily be repaired by any reputable phone repairer that offers microsoldering.

You can send it to iPad rehab ipadrehab.com they can retrieve data. It costs 300 dollars only if they get the data.
