The quick-start guide that I gave two days ago is hereby out of date!
On another Motorola hacking website, modmymoto.com, I found a vastly superior program called P2KTools. This utility allows you to access absolutely everything the phone can possibly support. It even lets you switch communications between P2K, AT, and Flash mode.
Best of all, P2KTools doesn’t require PST Phone Programmer to operate. Apparently, PST is a proprietary Motorola application, and is illegal for distribution to the public. The good folks at hacktherazr.com fail to mention this clearly (naughty!).
When downloading P2KTools from modmymoto.com, make sure you get the latest version, which is 3.0.8 at this time. For some reason they have multiple earlier versions also available in their Downloads section. Are they trying to confuse people?
Once again, to communicate properly with the RAZR V3xx, go into the program’s Settings, and check the “P2K05″ check box under “P2K Settings.” As we learned earlier, the V3xx only supports the newer P2K05 command set, and will not work with the regular P2K commands.
