Hi!
I was updating my Kobo Touch (N905C) with the official windows desktop app when suddenly a power outage powered off my desktop and interrupted the update process

.
Now my device is unresponsive and the led is glowing with green light. The screen is clear white. I tried to reboot both by holding the power button and by pressing the reboot button with a pin on the back, unfortunately both methods failed. The led glowed with blue light for a short time then changed to green, the screen turned to black for a moment, but remained the same clear white.
I got the internal sdcard out and examined it: the partitions, KoboRoot.tgz, and the upgrade folder seemed to be ok, the checksums in manifest.md5sum matched.
I created a backup of the sdcard and tried to manually upgrade the firmware with the latest
Mark 4 Hardware: Glo/Aura HD/TouchLC (Low Cost -N905C Model) 3.17.0 version. Still no luck, everything remained the same.
Do you have any idea what to do next?
update:
I checked the checksums in the
fs.md5sum files on the 1st and 2nd partition (with this command:
md5sum -c fs.md5sum | grep FAILED > /tmp/failed-md5sum.txt). On the 2nd partition there were no errors, but on the 1st one 195 files failed. I attached the list of the failed files.
