Okay, so I read you post and most of the comments. The comment before mine is asking the same question I am about to ask, but it has no responses so here I go.
I just purchased a DROID X from a guy on Craigslist, I got home bypassed the Activation, and all of that, it shows like it is still in service thou, there are a few apps that I know don't come with it stock. I am not new to flashing ROM's.
I checked my version and it ends in, .620.MB810.Verizon.en.US.
The phone is rooted, it has Superuser. it updates like it has signal from Verizon and displays the Verizon Wireless logo when I drop down the status bar. I have no intention on using the previous owners service, or going through their information or stuff, I am about to format the SD Card, but don't want to do it in case there is a file in there I need.
Anyways, I want to start from scratch and just format it or flash a new ROM, I have no interest in using it as a phone, just as an extra to play games on, etc. Can I install a custom ROM?
Also if I call Verizon will they deactivate it or something? I don't want to cause the person to have to pay for service or something.
