Per Google Translate:

Welcome to Android Central! From Google Translate:

"I have an a10s and I get a green screen with an error security error this phone has been flashed with

Good, I need help friends, I have an a10s and a friend wanted to update my cell phone and apparently I just screwed up I get a green screen with a security error message this phone has been flashed with unauthorized software and is locked and the bad thing is that it restarts and The truth only turns on, I don't know what to do, help, please, I need my cell phone"

Did you get the phone brand new, or was it already used? It sounds like somebody tried to modify it at some point, which tripped the phone's secure boot security.
