[Solved] Update MATE 15.10 for the Raspberry Pi3 won't boot

Support & Help Requests Raspberry Pi
#1

I have a MATE 15.10 running on my Raspberry Pi2 but even after all the updates it won’t boot on Raspberry Pi3.

Has anyone successfully updated and/or can suggest the steps needed.

Doing a re-install and restore all settings seems like a lot of work.

UPDATE

I decided to try rpi-update, which updated the kernel to Linux PiUbuntu 4.1.20-v7+

This works on both Pi2 and Pi3.

Unfortunately the inbuilt WiFi on the Pi3 is not found.

The following (cryptic) startup messages resulted.

[Fri Mar 25 12:11:41 2016] systemd[1]: Started udev Coldplug all Devices.
[Fri Mar 25 12:11:42 2016] systemd[1]: systemd-modules-load.service: Main process exited, code=exited, status=1/FAILURE
[Fri Mar 25 12:11:42 2016] systemd[1]: Failed to start Load Kernel Modules.

[Fri Mar 25 12:11:42 2016] systemd[1]: systemd-modules-load.service: Failed with result ‘exit-code’.

I finally resolved this by downloading firmware.

cd /lib/firmware/brcm/
sudo wget https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm80211/brcm/brcmfmac43430-sdio.bin
sudo wget https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm80211/brcm/brcmfmac43430-sdio.txt

#2

The Raspberry Pi 2 uses a 32 bit CPU and the Raspberry Pi 3 comes with a 64 bit CPU.

I would try a fresh install.

#3

I installed: rpi-source
by using the command (not as root):

wget https://raw.githubusercontent.com/notro/rpi-source/master/rpi-source -O /usr/bin/rpi-source && chmod +x /usr/bin/rpi-source && /usr/bin/rpi-source -q --tag-update

Then, I followed this documentation to build a new kernel with the drivers:
