I strongly recommend everyone on UNINSTALL the old firmware and reinstall this new one. The new firmware has the best "recovery" base design that should take care most and all of the known "update error"....please take a look at the "Safe Mode User Guide" in order to access the "backdoor" if your ESC encounter any kinda update failure problem...
