Hello community! I have Samsung Galaxy S5e and my trouble became after download app from link in comments of site -<edit> , I have download and install App and phone start rebooting, after reboot I have an error "Security error:This phone has been flashed with unauthorized software & is locked. Call you mobile operator for additional support."
and I understand that had update this morning, so I don't know finally reason of error blue screen. Maybe anyone tell how to fix it by myself?
Solved! Go to Solution.
I found out the cause of the problem, and I would like to apologize to the site - the link from their site had nothing to do with it, it was just a coincidence, thank you all.
