AFAIK elektro255 0.4a4 modded f/w is a combination from many firmwares. I've tried to open the CG1 using XVI32. I saw lots of offsets that differ from neither 4xR or 7xR. That's why Synerj tools from the previous version of elektro255 modded f/w doesn't work on 0.4a4.
Perhaps we should classify elektro255 0.4a4 modded f/w as new f/w version LOL
