Does every function work for you with Lenovo's kernel source for j706f?
I have a J606F (Normal P11 / XiaoxinPad) and Lenovo's source has missing driver for Touch screen, rotation sensor, wifi and various, the biggest being touch control.

You need to unsign the kernel to make other parts work, because they are not included in the source code

What do you mean to unsign the kernel? Could you please tell me more about it?
We do unlock the bootloader of the target devices in order to boot our custom built kernel, but is more needed? (I had been working on 2011~2014 era devices for the past few years and this is my first time working on a recent one, so I don't know much about today's locks, etc)

How did you ask Lenovo for the kernel sources or where did you find it? Lenovo still hasn't released the kernel sources for Lenovo Xiaoxin Pad Pro 2021 TB-J716F.

Probably from here:

Lenovo Open Source Portal - Lenovo Support VN

support.lenovo.com

but there is no TB-J716F and the other ones I think are not updated.

I wonder if we can leverage kernel sources from TB-Q706F since the devices are really similar in specs.
