1. Send it to Spektrum to see if they can flash the processors and get it working again- will cost you some cash and no guarantee
2. Search the web for the correct .sax file for your TX model. I have had success in finding a few of these for people on rcuniverse and spektrum forums
Option 2 is a no-go. The files are serialized. You may have had success finding a sax file for somebody else's serial number, but it won't work in your radio.
The Spektrum version of the post above can be downloaded as the "How to" file immediately below the big orange DOWNLOAD button on the firmware update/download page. It comes in the same 5 languages as the transmitter screens. It is attached here for your convenience. It's also on the RCG Radios forum in several posts.
Enjoy!
