hi all, i switched my blade bm7000s on this morning and all i got was a red flashing light on the front panel? ive searched for an answer and could only find to re-install the firmware via the engineers menu, unfortunately when i hold down the menu button and turn on it wont enter the engineers menu, it just stays at the red flashing light? is there any other way to access this menu? or does anyone have any other suggestions? im pulling my hair out here! lol cheers in advance for any help, its greatly appreciated.
