Pressing the Volume UP+Home+Power buttons will boot your Samsung Galaxy Note into Recovery Mode. This is useful if you encountered an issue while upgrading your device firmware and something happens that it just suddenly stuck on a screen and it only displays "Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again." Then the PC will not recognize your Galaxy Note even if you already connected it.
Here's what you have to do next if it happens that you might also encountered this kind of situation.
1. Remove the battery of your Galaxy Note (If you can't turn it OFF while stuck on the error screen)
2. Put the battery again but don't power it yet again. This time press the recovery mode button combination.
Press and hold the Volume UP+Home+Power buttons until a recovery mode screen appears.
3. Use Volume Up and Down keys to toggle these options.
