Lost android sofeware

[AC Question]

Put my phone on charger while it updated to nugart. Woke up to a little blue light and no phone working. Tried every step to boot phone. Left it to run out of power. Plugged it in to power and Galaxy came up and then kept going in a loop. Still not responding or booting. Phone is 20 weeks old. S7. Please help.

Press and hold power, home and volume down buttons until the Odin screen comes in. Press power button to turn off device. Now try to boot up normally. If that puts you into a bootloop again, repeat the process. Now try to turn on with power, home and volume up... If this doesn't help, but you can boot into Odin, best take it to phone shop where they have Odin software and hopefully they can get it going for you.
