i dont think there up to that number yet m8, when you boot it up the bootloader flashes up for a brief second after the dream logo goes off.
They are up to 75 so it may be that
Al
Ive got a m8 who has just had 3 deliverd with boot 65 on them which is strange as most of them are coming in now with boot 72 hes having a play with one of his tonight, ill let you know how it goes m8
Al
He has flashed one of the boxes with nabilosat patched for SS bootloader 72, when it boots up now it flashes up bootloader 72,
But he has done that at his own risk, but its working great, up to you if you want to do the same
