I'm anxious as well.... I only purchased the G2 because a quick search advised that it was rooted and there were custom ROM's for it...
Then I got home to find out it came with D80020c installed... I have Windows8 and can't change the com port to use the tools to go back to an the earlier D80010 version... My work laptop won't let me change the date to use the software... I'm FUBAR'd....
Disregard! I found this site that adds a dll file to the LG FlashTool so that I don't have to change the date and I also figured out how to change the com port in Windows 8.1! Just successfully flashed the older version.
