Has to be jtagged into the receiver.
The coolsat 4000 143b with 1.40 bootstrap instead of 1.20.
Backup your firmware first and jtag in with jkeys or jtag_up.
Experimental,I can't test it with all providers or switch/lnb combos.

The coolsat4000 1.20 boot .stb for those that want to revert back
to the original bootstrap rev.Unzip and load with the regular coolsat
firmware loader via serial port.
