You probably crossed the two dark green wires, one is GMLan the other goes to a front speaker. If you did mix these you will also have a burnt fuse in the BCM fuse block. I forget which one.

RDO fuse was blown replaced it and nothing works still. We did find out my headlights, horn and etc all work it's my interior lights that don't work and my cluster doesn't turn on nor the radio or trunk button and the car will not start. But my phone charger does work in the car and it's lit up.

Check the 50 amp fuse in the trunk by the battery. Am I to understand you wired up the new radio without disconnecting the battery?

Okay, check the 2 BCM fuses in the underhood fuse block.
