Question .fw file modifying?

[IBD3532]

I want to know how custom firmware is made. Is it just simply changed Chinese into different languages with hex editor?
Or can it be unarchived?
If it is modified with hex editor, then how can I change image in it?(like battery icon or footprints...etc)

I think it is a hard thing for a ungeek.

@Carl OK. I knew how hard it is for me to do this.
But can you just give me a point so that I can search on Google?
I just want to try. Thanks.

You can start with googling 'arm firmware reverse engineering'

Thanks.

@Kiril I'm very sorry for asking this question again.

I found that binwalk shows nothing with this firmware. When I searched on Google, it happens when firmware's entropy is all random(means firmware is encrypted) or it's just bunch of strings.
When I check entropy, I can see that the former is not this case. But I think the latter is also not this case.

How should I progress this one? I'm really really sorry because I'm ungeek(?)

How to modify Firmware file.

 

[IBD3532]

@MagicalUnicorn I now knew how to alter strings in my language. Thanks.
But how about making new tab? In Global firmware there is a word 'firmware by geek doing.com' on info tab. Is it just modifying strings too? You didn't made one?
And what about fonts? Where did you get fonts (and bold fonts?)

There isn't other solution .

@MagicalUnicorn So, you mean:
I have to disassembly the firmware to do what I meant, but it is difficult.
so you gave people easier solution because I don't have to disassembly if my purpose is just translation?
Then.... can you tell me what MB3's processor is? I have to know that if I'm to disassembly it.
Sorry for bothering you this much...

If you only want translate, read the tutorial I did, for more modifications yes is difficult, not all can be easy .

@MagicalUnicorn I asked you about processor of it, but that's OK. I'll just find out by myself. Thank you for your help.
