Armbian installation rescue after failed upgrade

[tpou]

Hello,

 

I have an OrangePi Zero H2 which until recently was running almost flawlessly with the Armbian_5.38_Debian_stretch_4_14_14 image.

 

When I did a kernel upgrade using "apt-get dist-upgrade" (because I had earlier the error message ~"failed to Load Kernel Modules", and dist-upgrade was recommended), and this dist-upgrade failed inbetween (probably because of power consumption), the SD card was left in unbootable state. (error msg see below [1])

 

I concluded that the /boot directory was corrupted, so from a new installation of Armbian_5.38_Debian_stretch_4_14_14 made elsewhere I copied all the /boot directory over to my SD card. This made the (first) SD card again bootable in the first stages, but it now will not continue after "starting version 232".

 

Is there a way to make the installation still working by copying parts of a fresh new installation of Armbian_5.38_Debian_stretch_4_14_14 over? I am asking because of the many changes made on the SD card in course of time.

 

(Such rescue method could be of general interest.)

 

Thanks
 

(I have meanwhile a new power supply.)
