Is there any way to change the start up and shut down screens on my v300? I don't want any t-mobile, or motorola on my phone if I can help it. I'm trying to blow out any and all predefined items...so if anyone can help I would appreciate it.

You need to read xlr8's motorola programming/customising.

google it

Thank you for telling me about the tutorial, however, I don't understand half of how to do the mods, even if I had the right programs etc. Is there anyone who has already mod'd their V300 and can give me a modding for dummies tutorial. I would appreciate any help. Thank you.
