HVAC Thermostat HELP!!! Seriously Pissed the F**K OFF!!!?

Question

Had an old Trane Weathertron Thermostat that worked fine and was wired 
G- Green
O-Orange
Y-Yellow
T-Black
R-Red
W-White
B-Blue

Changed to Hunter 44860 programable 2 stage heat/2 stage cool wired
RC/R-Red jumper to RH
Y1- Yellow
W1-White
O-Orange
B-Blue
G-Green
No Connect-Black

Nothing worked so, I called a friend (10 years HVAC) and changed to 
Y1-yellow
Y2-blue
G-green
W1-white
W2-black
O-orange
RC/R-red jumped to RH
Again nothing F**king worked!! Checked all breakers and they're all ok. No type of reset button any where and I believe this is a heat pump system. Air handler in the attic and compressor out back.
To top it all off I put the old thermostat back and wired as before and now that doesn't f**king work.

Any help would be appreciated, Thanks,
Pitch

beeb there done that , i think you shorted the xformer 24v 
It will be in the cabinet with the air handler

more than likely you have blown a fuse in your unit. Kill the breaker that supply power to it Take the cover off the electrical side and look for a fuse. It  will either be a in-line glass fuse or a automotive type buss fuse  replace with a 3amp. this is if you did not kill the power to it when you changed the thermostat in the first place. that fuse controls the 24 volt service to the thermostat

Did you have the power off when you moved the wires? If not you may have shorted out wires check transformer for a reset or if you have a meter check for 24 volts on R to common

For starters maybe a circuit breaker or fuse on heat pump in the panel. Your friend's diagram should work to finish the job; You need a jumper wire.
