Hey guys I have the illusion sat m4 receiver for some time now.....my friend who was in the know,used to update it via cable in the past(not sure how that works)....hasn't been updated since before 2012.....I've been wondering is there an easy to follow way,how to update it(is that even possible 2017?)...maybe manually updating the keys?...or anything else that would help..I know this might be old news(hopefully not)...however I do not have the funds/means to get a new receiver...living in Greece is tough enough,so any help would be appreciated
The latest firmware/update I have is -2.21......Thanks.
