Firmware 6.0.274403 - Page 6

rantanplan · 10-29-2026, 03:13 PM

One can't even try to install Firmware 6.0.279225 on a Libra 2 since there's no initial update via koboroot.tgz.

Does this mean the older devices listed will eventually be able to run the new firmware?

We don't know. I suspect they may want to but I suspect it will slow down those older devices with what they've got now.

Qt6 and their new rendering engine is just plain heavier to run since it's Chromium-based, and if it's struggling on a two-core Libra Colour, one can only imagine what it'll do a on a one-core Libra 2 that's slower.

It makes no sense then for the older devices to be listed.

Maybe for testing purposes. Not everything is intended for end users.

I tried the new 6.x firmware using this conversion firmware. I have a tolino shine 5 (Clara BW) though, so I don't know if it works on the Kobo variant. After sideloading you can use the update.tar on your link or update to latest version using OTA update. This firmware is for clara BW/Colour

I wonder why they chose chromium-based readers over webkit-based readers.

I've been saying for a while not to rely on webkit code and I was right.

I got the 6.x version offered as betaversion for my Clara BW. I installed it, tested it shortly and went back to the "official" version. Opening a book takes several seconds (same as Tolino does). The books have now an option to listen to books via bluetooth - this doesn't work at all; you can listen the title of the book but not the text you're reading. And the voice is like a computer voice of the 80ies.
Ok, its beta. But even a beta should work better than what Kobo offers here. I hope this is not the future of Kobo Firmware.
And of course...I would miss all the stuff offered here: Nickelmenu, Patches and KoboSync with CalibreWeb - all this does not work.
Kobo, please don't do this!

NickelMenu works....

The teng renderer is more modern than 4.x’s Kepub renderer. They do need to improve its performance, but it sure is the future of Kobo firmware. Seeing how slowly it evolves, it will take a couple more years until it works well, though.

I suspect that they will just release more powerful devices to compensate for that.

Falkor · Today, 05:15 AM

That may help with the speed, but not with the overall buggyness.

I fear they are heading towards Tolino Firmware, that has a bad reputation in Germany. The Firmware has always been buggy and slow - even it is running on the same hardware as Kobo. I have never had the experience with Kobo devices that opening a book takes several seconds - never. I just tested a Tolino a couple of days ago in a bookshop and it is laggy.
If this is what Kobo does for the future, I'll say good bye to Kobo.
