[Kernel downgrade 5.31 to 5.25 Olimex Lime2]

Hello,

 

I've downgrade Olimex Lime2 armbian from 5.31 to 5.25 with following commands:

sudo dpkg -i linux-u-boot-next-lime2_5.25_armhf.deb

sudo dpkg -i linux-dtb-next-sunxi_5.25_armhf.deb
sudo dpkg -i linux-image-next-sunxi_5.25_armhf.deb

and then reboot -f

 

Unfortunately Olimex lime2 cannot re-start !! How can I recover my board ?

Thank you
