[G1 Android Development] RichieDaze:
This thread was made for people like you. The OP hasn't updated this thread in a while, but we are here to help you....

Try to be creative with your scripts. I try to detail every edit so that people can understand what is being done. In the beginning, I didn't think this script would run. 100 flashes later, it worked perfectly and look a lot neater then the standard way. Sky is the limit with android...

Read my updater-script and tell me what you do not understand:
