thanks this is the same problem I am facing now with a friends solo2 clone
not sure if its se or not but only the button lights up no lcd display no hdmi output.
any instructions on how to flash this please guys I am not a clone expert

that was the same as mine.used the bootloader and all is good again :

thanks for your reply
just wondered what do I do with the file?
just put it on usb and boot or flash with rs232?
if by any chance you could give my some basic instructions I really would appreciate your help
