upgrade firmware openwrt arduino yun rev2

I also tried YunUpdater

https://www.arduino.cc/en/Guide/YunUpdater

But the project seems to be dead

Yun 17.11 Reboot prerelease - Arduino Yún - Arduino Forum

I got through the hardware of the rev2 update (power supply pin changed) but the software is a nightmare
for me while version 1 worked very well!

thanks for the replies.
