This morning turned off my phone by pressing and holding down the power button. I waited a few minutes then tried to turn the phone back on. It began to boot up by flashing the normal Samsung Galaxy SII screen. Instead of fully booting, it continually flashes the Samsung galaxy SII screen over and over.
I removed the battery for a few minutes and tried again... and again --> Still same problem.
Battery is fully charged. When I connected to charger, no change. When I connect it to my laptop, my laptop doesn't see it. By pressing power button and volume button simultaneously I got a multi-colored prompt with option to reboot. Tried the reboot --> still same problem.
Took Izzy's advice.
Got phone in "manual mode", tried:
- "reboot" --> no change
- "wipe cache partition" followed by "reboot" --> no change
- "factory reset" (aware that I'll loose my contacts, photos, etc.) --> worse
Now can't get "manual mode" at all, logo flashes more frequently, and when I press power and volume buttons (the only buttons my phone has!) I now for a very brief moment see one yellow message

Update: downloaded Odin 3 v.1.85, flashed with Stock-SGH-S959G.tar.md5
STILL HAVE THE SAME PROBLEM, WHAT ELSE CAN I DO? (also checked SamMobile for firmware = nothing available)
