the boot sectors of these receivers isnt known yet m8, so playing with 'backup' images is all untested waters, if you were to create your own backup, its work on your receiver every time
as long as the UR releases work, id say theres not a problem with it
i have the same issue with the latest HDF release, no matter what i try, it just wont work, ive tried EVERY way possible of flashing it onto it
I have made my own backup digi and it will not boot it gets stuck on the start up screen everytime either flashing via miniroot web interface or via usb stick. Either after flashing fresh ur image or a factory reset niether rectifys the problem.
