6210 flash error

[tanvics71]

Hi, I've a 6210 with a big problem ( I think ) When I try to connect him sometimes he doesn't work but in other ones the lights of screen and keys starts blinking for a few moments then it turns off again. I've tried to flash with Rolis, Dark Flasher and Knok but I coudn't connect the phone. With Dark Flasher occours an error message "Boot init Error! (Phone RAM is bad!)" does anyone had this problem already? What can I do? I tried to search in the web but I didnt find nothing.
Any sugestions?
