[Android Software Development] szczuru:
So is there any way to repack firmware? I have similar TV - Thomson (TCL), I was able to extract firmware via binwalk - i need to change one thing - font 'cause default font doesn't support all characters from my language. I found ttf file inside this firmware, replaced it but how to repack firmware now?

this font file is inside

tvos.img

and

system.img
