What does the screen ODIN MODE mean?

[Android Central Question]

I was trying to reset my phone because my unlock pattern would not work. I never took my battery out of the phone, but the screen is showing the ODIN MODE at the top left and the main part of the turquoise screen has a large down arrow and the words
Downloading
Do not turn off target
I cannot get my phone to do anything. I saw the answer where someone suggested taking the battery out again, but I never had it out. The darn problem with the unlock pattern not working on my phone came a day or two after Samsung suggested I do all the things they recommended in case my unlock pattern is forgotten. You can't tell me they're not having this problem from a update!! Help please!

Odin Mode is for flashing firmware to the device. To get out of it long press your power button for about 20 seconds and it should reboot normally.
