FRSKY X12S 'bricked' need firmware flashing instructions

A member of my flying club has asked me to try to mend a Frsky x12s that he bought new only about six months ago. From what I understand he tried to load OpenTX onto the radio but did not make a backup of the original FROS system. The transmitter is completely 'black screened' only the charging light is on when charger plugged in. I have managed to 'wake up' the tranny by downloading the Open TX firmware to an SD card using Companion software but my friend wants it returned to the original firmware. I refer to a previous post as below which mentioned a 'Mike(jet-flyer)' who has helped people on this forum reinstall FRsky original firmware under these circumstances. Any help with a walkthrough of the process or a method of contacting Mike would be appreciated .

Looked at your post and see Mike (Jet-flyer) has picked up your post. He is one of the guys that helped me and is the author of the instructions on the FrSky website.


Mike is usually monitoring posts on the FrSky Horus thread over on the RCGroups forum or the Horus facebook page.
flying's easy - it's getting it back down in one piece that's the hard part


I have managed to upload a dfu file to the tranny using companion. Held the power button down, Updating started, Note- Flash done, 'welcome to HorUs'. Then downloaded the latest bin file eu1503 frtx to an sd card did an update so the tranny is now reporting
Hardware X12S EU14
Software 1.5.03
Unfortunately the opening screen is not the expected HORUS splash screen but when the tranny is switched on it goes straight to 'create model'. When I try to create the first model it asks me to load what I have entered and then displays a dialog box 'config file is not exist' . CANNOT GET PAST THIS. I can get into the 'SYSTEM' 'MODEL' And 'Telemetry' screens to no avail. Help Ive been on this for too long!
