My Samsung Galaxy S5 mini suddenly shut itself down and when I try to boot it back up again it stays in the booting up-screen where it says SAMSUNG. I don't want to fix my phone, but I just want to retrieve my lost photos and WhatsApp messages from my Samsung Galaxy S5 mini. I've already tried some tools, like FoneLab, FoneDog, Dr.Fone and Jihosoft, but they all didn't work for my phone. For some I had to start up my phone, but it won't, and others only worked for other Samsung models. I already tried filling in another model than my one, but it just said downloading on my phone for hours and nothing happened. Is there something I missed or another tool I can use or even another method to retrieve my photos and WhatsApp Messages?
