how can i change my bootloader version

[Guest karmakula]

Hi Doctors,

I have a problem with my voyager, I was able to change my rom from Smart to Qtec to Orange and back to whatever rom, but yesterday I used an Orange Rom with a 2.6 something version. after installing this rom i noticed that my bootloaders version changed from 1.07 to 1.06, now i can not change roms i keep getting errors such as the image is not compatible error 117, error 113. I think if i can upgrade my bootloader to 1.07 again the error I am encountering will be solved. How can i change my bootloader to 1.07 again and where can i get those files. Please help me, thanks.
