KOBO AURA V2 Bricked need image

Hy all, I'm new here.

I'm totally lost. I had some battery issues with my Kobo Aura so i installed a new battery. Unfortunately, it was still draining extremely fast.

Then I figured out how to downgrade the firmware. And it did help a bit but still drained fast. So I tried another firmware and as you can guess its bricked now. I see some weird stripes on the screen and it's not rebooting or resetting.

Tried everything and I put the SD card in the computer directly and copied firmware but no results. Screen stays on see: https://postimg.cc/R3zv7f2Q

Is there a way to fix this or can someone send me an image of the whole SD card so i can copy it?

I think im screwed. :(

happy to hear.
Thnx
