Im like you busy with a real life too, i have read all your post but im 44 years old with no background in programing or doing IT stuff! It's an age where you learn slower!!
What you guys not understand is that im not even a native English speaker, i learnt this language by my self so this said combining the lack of IT understanding with a bad english results in me taken as a trol which im not! Maybe stupid but not a trol!!
Also i need to say that i did nothing with the player what i haven't been told to do! The USB TTL and Mtktool method for me was the easiest to understand! I used the downgrade.bin then the MAIN20XEU extracted from the 45 official EU firmware the via internet from the players menu to the latest so if this screwed up the players ability to playback Blu Ray disc was because i followed instructions from here not something i came up with!
I dont want to say that you guys are to blame, is my fault because i have been playing around with this firmwares but please dont tell me player is screwed cause i wasn't following recomandations cause i did followed them, didnt i? Followed all the steps for downgrading via USB TTL module!!
Also the overlay and sftp didnt worked for me,i could not sftp into the player so i bought that TTL module!
