Suck on samsung screen - Need help

[Gerry Nguyen]

Hi everyone

My phone is stuck on samsung screen trying to boot up.
Ive held down volume down/home/power button and takes me to "warning" OS can be critical - volume up to download ( then gets stuck on download screen "do not turn off" or restarts the phone only to get stuck on the samsung screen again

Any suggestions

Thanks
