Having issues with the box. The box is fully loaded with server and extensive iptv package.

I've read the box needs to be flash with a new image. Currently using Wooshbuild v6 openATV.

Can someone give me steps to what I have to do.Where to get the latest build.Also if I flash, will I loose everything on the box.ie server details channels,iptv/including username password etc?

What's the best way to approach this as when I flash so I can put things back on easily. And have my same set up as previously.

Thanks
