I got a CDM1550 ls turned into a 1550 ls+. Now I know this software update is frowned upon by the big M

, but I am now having a problem. I have no power coming out of the radio. I can not hit a repeater less than a mile away, but when i go to talkaround (direct) it works with a radio in the same room. I am wondering if there is a way to flash the radio to get the power to work. I know what you are all thinking, he has the radio on low power. That is not what happened. I have tried on both High and Low power and nothing comes out. Also I know it is not the antenna, because it works great on another radio.
So basically does anyone have any ideas of how to make the radio work. Also i was told it might be something in the global tuning. I do not know much about that program, so if someone can help me with that too. I looked at the radio compared to another radio, and the settings were very close. So I am assuming that is not the problem.
