I've followed the instructions precisely and keep getting the same message whatever I do: Sorry, this firmware version is not supported: 505.1.1.00.18040
I've installed database on internal memory, igorsk and new_opt.img on SD card (tried more than 1, all formatted FAT). Dismounted my 505 from computer pressed 4 and then message as above. Tried several times including a reformat of internal memory. About shows my version as 1.1.00.18040. The reader hasn't changed and still works as usual. Only change is to contents of Pictures folder... now got labels, labels, skinMain and skinMain (game graphics)
Any suggestions
