MKII - Changing strings , possible ?

[Refugee]

Hey

My friend has a MK 2 device on board . He asked me about changing few strings (text) in his MK2 . I thought it would be quite easy , but the thing is that NavTweak doesn't open any "navboots" that contain MK2 files . I'm just wondering if there's a way to change those strings ?

Waiting for an answer ,

You didn't understand me well, mate .I asked about changing text in main menu and so on , so far I've been doing it by NavTweak ,but in MK2 it shows incorrect format . I guess , I cann't change those strings by replacing the hex code . Does anyone know how to change 'em ?
