My new RK27sdk MP5 PLayer - help

[trej]

Hi guys,

This is my first post, this is a great forum you have here Anyway ive recently bought a touchscreen MP5 player (4.3"), according to the system information the product name is RK27SDK, Major Version 2.3 and hardware ID 090114.
Now I know it sounds picky but the spelling is incorrect on all of the menu items and half the words are missing letters. Im just wondering does anyone have any up to date firmware for this player? Hopefully this may fix the spelling mistakes as its doing my head in!
Also ive had a good look around the site but couldnt find a how toof any sort on how to upgrade the firmware on these particular players and also how to make a backup of the current firmware, can anyone help?

Bit of a dissapointing response to chaps. I managed to alter the spelling using StringSearcher.exe downloaded from this site I beleive. Its awesome, managed to manually alter each of the strings. Have also altered some of the images successfully with image searcher

Does anyone have an up to date manual for these by any chance? Mine is for a completely different player
