Just rooted my week old 6.3 Fire using the KFU 0.9.5 utility and a little manual work with ADB to get the market working correctly under Go Launcher. Now I just need to decide which ROM to flash. I have a few downloaded that I grabbed through XDA the other day. Not convinced yet to go to a ICS based ROM or stick with the myriad ROMS based on CM7 that have everything working. Any suggestions from others would be gladly welcomed!
