thank you everyone, I copied the 2 files into the .update folder, rebooted and it upgraded from 8.02a to 8.1,10 successfully
( i did leave the device tree as : - gxbb_p200_2G_1Gbit.dtb )
edit:
something that I have noticed with - 8.2-8.1.10 is the sound appears to be dropping out slightly, watching a film in Dolby Digital 5.1, my Onkyo amp is picking it up as before, but the sound appears to be frequently dropping out,, when on 8.0-8.0.2a this didn't happen
edit (2):
pretty sure it's just this particular video file
