Sadly I'm in the same boat. After a year of 'research' I ended up buying a dingo A380E on eBay and complete naivety led me to think that what I was buying was an A380 *very sad face*
So now, I'm sitting here, Dingoo A380E in it's box on my desk, message sent to seller to return item, kicking myself, but... Like others have mentioned, is the A380E just a repacking of the A320E? If so, could we use the CFW for A320E and get something out of this mistake... which is, I'm sure, a question that must've crossed my parents mind at some point...?
Any advice would be great.
Lesson learned and square one isn't so bad.
