My brother bought a few Android boxes similar in spec to these models.......here
He bought quite a few of them rooted with his own branding on them and had his own firmware sent to him.
I was wanting to use one for XBMC which works great and for a retro games machine and this is where i am having a problem, i bought a g910 gamepad to use on this android box and switched on blue tooth but the switch immediately switches back to off.
I remember having this problem a couple of times with custom roms on the phones i had and it was usually sorted out with a fix from a developer.
I am hoping the Chinese suppliers that made these machine will send him my brother a fix or an updated firmware but there has been no reply back yet.
I would like to ask you gurus here if it is possible to fix this problem myself?
Could i use root explorer or something to repair the blue tooth problem?.......the firmware is currently on 4.4.2
I would appreciate any help.
