Thanks @jhon3909!!
That is a complete guide, but I don't want to change the complete OS, just
Kernel.
I will avoid the microSD option by the moment. In future, I am sure that in
future I will make a fresh installation, so it will be helpful.
Here is the ouput I have got:

Reached this point, I want to sum up:
- Install cross-compiler.
- Get uBoot: *ftp:://ftp.denx.de/pub//u-boot/u-boot-latest.tar.bz2*
- Get kernel from: *git://github.com/beagleboard/linux*
- Build the kernel and modules (*make ... uImage dtbs LOADDADDR=0x80008000*
).
- Copy the modules to: */lib/modules*
- Create tftp server in host-pc.
- Launch uBoot on BBB (use serial port).
- Configure @ips.
- Transfer zImage: *tftpboot 0x82000000*.
- Boot from new kernel: *bootz 0x82000000 - 0x88000000*.
These steps from above didn't work too.
Can anyone explain the concrete steps that must be done to build and
transfer the kernel, *please*?
What about the files needed to make it works? (/lib/modules;
am335x-bobeblack.dtb; uImage; zImage)
