Libra colour bricked
Hi,

I bought a used kobo libra colour which was stucked on the home screen.
I tried several reset, soft and hard, tried to unplug and reconnect the battery, without success.
I put another battery in it (from my personal working libra colour) and it finally shows an empty screen then a yellow one. If I reboot it, same pattern, and it ends up to a yellow screen, without text nor image.

It is not detected by my computer.
I guess it is a firmware issue, but the motherboard being without sd-card, how to solve it ?

Do you have any idea ?
Many thanks

Not very helpful but you could try contacting Kobo for a warranty return. With the release date being April 30, 2024, the warranty should still be effect.

Unfortunatly no, the seller bought it refurbished, with a 6 month warranty, which is over …

Have you tried the key combo to force a full reset?

If a full reset is page down or page up + power button, yes I tried. But it still ends up to the empty yellow screen

I'd contact the seller and try to get your money back.

I bought it for parts. It was a bet, I lost …
So we agree that with this model we can’t flash manually the firmware ?

Probably not, but worst case scenario you only have to swap out the motherboard. At least it's not as expensive like the E-Ink screen.

I tried to plug the screen in my working libra colour, it works ! So yes, I only have to swap out the motherboard.
But it’s a shame I have to do it because of a software issue …

It could be a hardware issue...
Like one chip on the board is dead, or the storage itself. Which ideally should be swappable like in earlier models.

A quick update.
I finally bought a new motherboard and the libra colour now works rock solid.

The motherboard comes with a firmware v4.39.224439. I’m not able to set the VCOM value, the iFixit method doesn’t work.
Maybe the new firmware is able to set it automatically ….
