Well here it goes: i installed the tp on my l520, went fine phone booted up, got win 10 tp, everything cool yes? wrong, wifi won't connect no matter what i tried, removing my routers password and let the network open, didn't work, soft reset, didn't work, and so, i finally say **** it, i'm hard resetting your ***, hard reset when fine except now the phone won't boot up, it turns on and pass the carrier logo but after that i get a black screen, i suppose something really went bad with the phone, though the computer stills detects the phone when i plug the usb cable so nokia software recovery tool should do it's magic, in any case, i post this as a PSA
