Device: Kobo N437 Glo HD
Question Kobo does not boot new flashed SD Card

Hi There!

Guys, I need some help about Kobo glo HD.

I received a img file for kobo glo HD N437 on this forum (Thanx for that!!! ).
So I bought a new SD card Sandisk 32Gb Extreme and flashed the img file
on it via DD in Linux. I resized partition to 32 Gb. Kobo just turned on red light and nothing else happened.
I redownloaded image and reflashed SD card via Balena Echter and no partition resizing. Same thing.

The thing is, the Kobo was performing endless restore process with card I have bought it with. It was not original, it was 16Gb. I was trying to restore it, as it bricked before for many times for no apparent reason during usage...

So I guess the image file you've got on this forum works fine for you guys?
The Sandisk Extreme is new and should be compatible with Kobo glo HD right?

Any suggestions? I tried to reset it by holding off button for 45s and turning it on for three times with quite a pause between steps, but it didn't help (If the restore process is still in memory, that should reset it I guess...)...

Help would be much appreciated! Thanx!
Regards.
