WooshBuild Reflashing my Octagon SF8008


hi, I have an Octogon SF8008 with Openvix installed but it’s starting to bug out like when I try and change skin it just crashes and reboots and it can’t see the WiFi built in and only allows me to use Ethernet so I am trying to reflash it as OpenATV so I can install wooshbuild but everytime I try and install the flash when I’m in the UPDT screen and recovery from usb it gets 6% done and goes back to The options to update screen. Recovery from network gets as far as downloading the first step 100% then crashes.

can anyone help please.
