CloneD you have to use multiman CEX on DEX firmware to convert froom DEX to CEX, see the last part of the tutorial.
Please be adviced, that 3 soft-bricks (see Tul, Piratian and mine) had occured in that process DEX to CEX. At least me andn tul (Piratian did you changed too?) had changed the region (CEX 85 to DEX 82) and we suspect that is something reggarding to this. So be careful
Mine was 84 to 82, I didn't change region and THAT, that you pointed out above IS NOT in the tutorials I have and I have read and kept up with all 29 pages of this thread and I THOUGHT I had updated the tut every time DeanK changed the links and/or every time someone made a change, I don't know how I missed that. THANK YOU, andreus.
EDIT: YUP, I just bricked to with the 8 beeps and same shit you all had.
