In this video we will use the Spectrum Programmer to reload the locked AR637TA firmware that comes with EFlite BNF models with the unlocked AR637T version. Next, we will use transmitter Forward Programming to do a factory reset to make sure all AR637T programming options are available. The result is a completely unlocked AR637TA receiver with all the options, features and factory settings that come with an AR637T that you would buy from Horizon (except for an altimeter.)

Note: This will also work for the Spectrum AR630 and AR631 6 channel receivers with Safe technology and Forward Programming access.
