Hello everyone!
My Kobo Clara HD screen is stuck on this booting screen with the power button crossed out. I have tried everything -

The first time it appeared and got stuck, I kept the reader on charge and tried powering it up again nothing happened.

After reading up online, it seems like the microSD card inside has been corrupted, which turned out to be true as I had inserted the card in the laptop, and it came up mentioning it has been corrupted. At the same time, the screen is still stuck on this.

I disconnected the battery and the screen, but still, the screen is stuck on this.

I tried flashing the .img file onto a new microSD card, which was done successfully, then tried booting up, but again, no luck.

Would greatly appreciate help to make this work again :')
