Strange start up on s5

[Android Central Question]

Hi a have a old phone s5 I have lots of stuff on, still has a sim but rarely use it as a phone its off most of the time.
Last time inturned it on i had a very strange voicemail, basically trying to get me to press a digit.
After listening to the voice message, I turned of phone today when I turned it on instead of the normal start up .
I got a list of commands in green,red ,white writing like computer type.
About securerboot, udc ect ect
Has my phone been hacked connected to a computer?

Download Mode or Recovery Mode, perhaps. Hold Power until the phone powers off. Wait half a minute then power on again.

Tell us if you still have problems.

Ask your carrier about the strange voicemail.

Welcome to Android Central! That doesn't sound like a hack -- it sounds like you got to the bootloader. Take a picture of the screen and show us: http://forums.androidcentral.com/ge...ide-how-post-screenshots-android-central.html. You'll have to register first.
