If these very important files are in the internal memory, and not on an SD card, and you don't have a backup, it's time for professional data recovery. That's not free. But if these files really are very important, you wouldn't mind to pay a few hundred bucks, I assume.
Hey,
One day I was using my Nokia Lumia 925 and it suddenly went dead although it had 50% battery charge. I've tried a soft reset and recharging it, but it doesn't seem to react, no vibration, button light, anything. When I plug it into a computer, it is detected by the PC for a second, then it disappears. I tried the official windows phone recovery tool also, but it wont recognize my phone.
Theres some very important files on the phone's storage, and I'd like to access them again. I didnt backup the files to a cloud.
I even ordered a new, OEM battery for the phone. When I first plugged it in, the light on the windows button went on and stayed on. It still didnt react to anything. I tried with a PC and the same (detected-disconnected) thing happened.
Any hints on how to proceed? Is there a way to remove the internal storage and access it with another machine?
Cheers, Osmal
