the odd time you could online update to next image but with all new things added/removed you have to start again from a new box setup as backups are of no use and drivers not compatible and they write a whole new image now called HADES.
when moving from all those different names before a brand new flash is needed and i would also do a new flash if box had problems and start again using no backups restored [ bugs/errors ] so you start with a clean slate.
the more you flash boxes the easier it gets,important bit is to save your files to pc first so you can ftp back [ line info ]
forgot to mention if box is working and your happy you dont have to upgrade,when you get the message feeds are down message from the download plugins could mean no longer supported or support is been upgraded hence check on wos for green icon first before reflashing a new image.

the great things about e2 boxes is excellent support like the best pdf file for setting these boxes up makes life a little easier,there are many helpers on techkings to guide you if you stray.
main needs of new box hdd to record to and will need to be mains powered.
2 sat feeds or 1 cable + 1 sat if getting a combo box
2 good usb sticks,1 kept for flashing these boxes i use an 8gb integral as it flashes red when doing something,other is a kingston 8gb micro usb for epg =permanantly in box.
an ftp program like filezilla client to send your files to box
there are others but not used them.
box can be flashed with latest image you prefare VIX
you only need to download your cams to box first
the rest is on the tuts.
