as this is an older player (if it is the same as the one in the photo) you will need special tools (consumer update) and some firmwares to try and recover with
firmwares marked vx858 will be for your type, but there is NO gaurentee that it will work, many of these player look the same but do not use the same firmware
note you mention 27sdk, where did you see this info, on the player, if so its not a player like the one linked, we have to be sure exactly whay player you have to help out as they are not all the same
