Great, glad you got it working! Soldering it with an iron would not be fun at all. Using hot air and solder paste it is really quite simple, the hardest part is applying the solder paste and placing all the components.

Far as the manual, I am not 100% sure what firmware you used but I assume it is the GT70 firmware, in which case the GT70 manual should be what you want. Although really it is very close to the normal GT firmware, just tweaks to the mode sets and minor things mostly.

There are some strobe modes, they are just disabled by default. You can enable them in the menu.
