Question Half Bricked S9?

Was trying out several newer versions of FW this morning, all having audio issues with me so I melded my latest usb dump with the stable March FW using the editor. Loaded fine, got channels and sat motor movement fine. Hit the menu button and black screen, no response. Hard boot, recovered channels, sats. Menu, Kills. Need to force load stable FW, factory default? No idea how this is done. Need the menu to blind scan and other stuff!

Thanks in advance!

P.S. Glad your back up and running, missing all the old posts and stickies though...
