O.k. so you have a wire soldered, from tristate to SBE on e3 ribbon? Or tristate to ground?
If you have tristate to sbe, have 1st switch up and the rest down. flash backup, then put all switches down and boot to recovery menu.
If you have tristate to gnd, flash backup with all switches down, remove wire, then boot to recovery menu.
