No crank, just started this morning

Yo, new here so I'd appreciate the help. Got my car back from the mechanic yesterday and drove it home. Needed a tune up so I started the process with freektune right away. Next morning I get in the car and start it with no problems whatsoever. Turn it off and try flashing the ecu to a different tune. successful. Try to turn it on again and it won't even crank. My first thoughts go to something fuse related with the starter, may it be a clutch switch of the fuse on the battery itself, but then I think well this only happened after I flashed the ecu. So would it be something in the pcm that's just not having it? I don't know.

 

Probably a bad flash try reflashing the tune
