I have a dead (flashing lights G30 bodypack.) Replacement is 1/2 the cost of a whole new G30 system complete... Anyway, from what I have read, A G75 can be used with monkey updater to re-slash\firmware update the G30 bodypack. Can this also be done with a G90? I have rented a G90 for the next gig, and figured since I have it on rental for a few days, I might be able fix my G30. Appreciate any help!
