Installing ROM's on your xv6700??

[TM]

Hi folks long time lurker first time poster.

Well my question is this.

What is lost on a ROM install? What Original ROm would i need to back up/flash too should my phone need work by the VZW techs?

There are so many ROM's to choose from i don't know which to try/use?

Also most of them seem to talk about the Sprint PPC-6700 now while i know that they are the same model, Carrier wise they are different.

I've read about Carrier specific extended ROM's is that just a ROM that included the info to allow your phone to communicate with VZW's cell towers and work on their network?

Also what improvements are there over the Original ROM's compared to these?

Like a side by side comparison?

I realize thats a lot of questions and I do/have make it a point to search for my answer's as I am a Mod of my own site but I've either missed them entirely or skimmed past the info i've asked.

I'm very knowledgeable in the field of PC's and general tech as I work Technical Support for Verizon FiOS but after searching around and getting half answers or missing said posts i figured I'd just post politely and to say hello.


So.....Hello!
