Hey all. I've a got an old LS720 that was originally a Virgin Mobile phone. I now need it for a pretty important project and already have the correct unlock code directly from VM. The issue I'm running into is the phone won't let me pull up any of the unlock menus. I've tried all of the dialer screen codes, none work. Like literally no codes do anything on the dialer screen. The phone in question is running 100% stock firmware and software, stock dialer app, etc. Never been messed with.

What's my best plan of attack here? Is the v8 rom the roadblock? Flash with an older rom?
