Finally I have managed to flash my Azbox Elite HD with openRSI enigma image. I must admit all my efforts were nicely rewarded as it seems to me enigma is much more capable than original image.
The upgrade operation requires a RS-232 TTL interface which I have purchased on ebay. Here is a hint: there are some ebay auctions offering Azbox firmware recovery cable for 20 quid or more, these are basically USB to RS-232/TTL cables I’ve already mentioned. You can save few coins by looking for USB to RS232/TTL PL2303HX Cable which probably you are going to find for around £5. This is exactly what you are going to need to flash Azbox and I promise you this free of charge.
Next post will provide full step-by-step upgrade guide.
