My father has done a reset by accident on his smartphone.
He has very important data he needs that was deleted.
Is there a software/app/way that will copy the internal memory (hard disk) exactly as it is byte-by-byte to my computer (also copying the "empty" parts of the disk because this is where the deleted files I want to recover are located)?
I want that as first step because I see there are a lot of different software that offer that but I would rather try more then 1 in order to extract as much data possible (they each have their pros and cons). Most of these programs also install an app or tweaks stuff on the phone and I would like to use each on the original copy.
