Help me flash my 6800 ROM back to stock!

[ffk_pennywise]

Hello,

Yesterday I used the automatic installer program on phoneNews to upgrade my Verizon xv6800 to enable GPS. Its the DCD ROM. I hate my phone now, as a lot of things are no longer working. For the love of all things holy, someone tell me how to put this thing back to its original state. I'm extremely new to this so walk me through with baby steps. What do I need to download and in what order do I install. The only thing I like is the threaded SMS with no delivery notification so if you know how I can keep that, I'd appreciate it. I really need help on this and I really appreciate it. Thanks all!
