not starting, reset not working

My H20 (2014 edition) is not starting anymore
I have koreader installed and was reading a pdf when the reader stopped responding. It froze on a page with back light on. After a while the light got off.

I tried charging, pressing and holding power switch, pressing reset with a needle - all the things previously worked in this situation - nothing helps.
The reader still shows same frozen page. After connecting to charger, laptop or pressing power button the led turns on for several seconds like it's going to boot (laptop recognizes "NS Blank Codex" but doesn't show the drive), than it goes off again.
There was an update recently which I chose to handle as "partial update" by the manager at the start (forgot the name) where you choose between nickel and koreader, but the reader has worked fine after the update

What should I do? Disassemble and disconnect battery? Flash sd card? Where do I get the firmware? Try something else?

I think you may get faster response in the regular Kobo Reader forum instead of the Developer's Corner...

try replacing the sd card then

careful when opening this device, a lot of glue all around, easy to break the display

I did this. Don't know what exactly did the trick: I disconnected the battery and removed the sd card and put it into my laptop. After reinserting the card the device booted again.
The device wasn't even reset to factory settings after all my recovery attempts
