When they brought the BM5000s out there was no 9991 version available.
I thought they may have gone to a hidden menu like the Skybox / Openbox
but it was still a patched version of the official firmware that was still needed.
Somebody on here then Emailed me a copy.
None of the official versions have the 9991 option, is that an official version ?
All previous blades models have had there own specific firmware so I wouldn't
try to flash the BM5000s patched version unless someone confirms it can be used.
Try blade online and see if both boxes use the same official firmware, then you will know for sure,
just tell them your box is stuck on boot and it needs re flashing or some other load of rubbish lol
Have a look at the people who have uploaded the patched versions on to the site and
send them a PM they may be able to help.
Just thought of another thing, if it is the patched version, do you also need to load a blank config
like the BM5000s to get the 9991 option to work ?
