5linx velocity v2 - touch screen doesn't work

[WarSxNes]

Hi it's me again....

Months ago, I wrote a post asking for help and I'm still waiting for help. (don't care about that)

Now, I found a custom rom that work well (99.9%) for my tablet, (gcensor, mouse usb, wifi, etc.) but touch screen doesn't work.

So, someone know how to add a touch screen driver in that rom?

Hi welcome back.

I'm almost certain you can't just add a driver to a binary ROM. This is something that has to be done when a ROM is compiled/built from source code. Which is something that usually only the original manufacturer and third-party ROM devs do. e.g. Cyanogenmod. You might be able to do it if you can get the source code for the custom ROM and required driver, plus the appropriate build tools.

Hi mikedt you again, xD.

Actually, I found a tool that do that work for you, but is only available in Thai. And I have the version 1 of that tool.

That tool give me those parameters to fix the touch. But I can't found the file to modify.

You can see a lot videos on youtube from them. Of course all their videos are in Thai (I don't speak Thai), and they show how to use their tool and fix the touch, but I don't understand the part when they opened the file to modify. After they do that, they save and repack the rom and that's it, touch is working again.

Well, that is the manual method, because another newest version of their tool (I guess is the version 4), show that you can fix the touch just with one click. But I can't find where I can download that newest version.

I just know, the file I need to modify should be on system/lib/modules/ because in that folder are a few files in *.ko format

Dude do you know how to use Linux???
what do you think (P) means? = paused

Note: Forgot to say, all of this is only for rockchip tablets. (in my case rk3066)

And if someone know how to add a touch driver I'll be glad you.
