[Asterisk-Users] Grandstream BT100 and firmware

[My Other Email]

Here's the problem I'm having...for some reason, my BT 100 has downgraded 
from .18 to .16

I have downloaded the zipped file with the .20 but how now what are the 
instructions to actually download this to my phones?

Not quite sure how to proceed.

I've flashed other devices before, but usually they have a program to help 
you along the way.

thanks,
Alan
