You'll need an unpacker, then you edit with a hex editor.
When i get home i'll see if i have that software

Thank you a lot for help. Can I use GHex on Linux or HxD for Windows? I have Arch dualboot with Windows 7

Easily :D
SISContents does the job well. If it is already a modded avkon, just edit it directly. Or if you want to edit the original avkon, you might need to convert it to the older version first. SISContents can also help you with it, just specify 102827CF.dll as an intermediate so that the conversion is done properly.

The primary step would be unpacking them, as matthew mentioned. Only one packer exists for Symbian, which is called Petran. Luckily, Petran supports unpacking too. Newcooller made a top-up on Pertan namely Petran GUI, get it to make things simpler.
Then you need to disassemble these binaries. If you know assembler for ARM processor, I can give you a bit of further information. Otherwise stop here because you will not succeed.

Maybe as a sporty challenge - yes, if you know by heart common hex patterns of the main functions :)

Thank you very much. So let's start with qmltouchiput.dll (Belle FP2 Keyboard). Which tools should I use to edit this file? Hex editor (GHex)? Or extract it first (but if, so how)?

Now I see, that it is't as easy as I thought. I will try, but I don't have much hope...

1) Unpack with Pertan
2) Disassemble (with IDA, Ghidra, maybe something else) and study the file
3) Apply patch according to your needs

If you want to edit text strings inside these binaries, then your steps №2 and 3 would be finding and modifying the string. For this purpose, any hex editor will suffice.
