If you go into More => Settings =>Reading Settings and remove the checkmark from Show Adobe EPUB page numbers that should get rid of the extra page numbers.

However, is it possible that this patch is no longer required? I've just opened a kepub and an epub (both previously unread) on my Libra Colour with 4.45.23640 and the font-size appears the same in both.

It would be good if someone else could confirm/deny this potential good news.

It looks like someone at Kobo might have finally read my patch notes, because I think they have indeed fixed it.

I loaded this firmware into Ghidra, and it appears that Kobo are now using the ( font_size / 15.0 ) * 96 formula my patch was trying to replicate with different numbers.

EDIT: I am very rusty with this though, so take this as a grain of salt... And the problem was always device dependent depending on the devices screen DPI.

Yes, I discovered that later. I had to crank up the font size a lot for my ePUB in order to read it as I was used to. Font sizing seems now to behave like the KEPUB viewer.

The "About KLC" page is called "eLabel", and is only loaded (on manually updating) when connected via WiFi. Otherwise you get an error massage stating the document cannot be found and you must sync.

That is my KLC experience as well.

Thanks for adding your second opinion, @sherman.

I agree that the problem was always restricted to certain models but I never did know exactly which models were affected and which were not. I believe my KA1 was in the "no problem" camp but I'm fairly sure that my Libras and Claras did have the problem unless your 'Unify' patch was applied.

It affects Clara 2e as well - I am anxiously/impatiently waiting for new FW to fix it!

Hi, Where can I find the Firmware to download please? I looked at the thread on the Developers Forum but I couldn't see anything after 2022. Thank you

This is the first update available since I purchased my Colour. I use NickelMenu and have KOReader installed, but don't use it regularly. If I run the update, will it mess up either of these? And if so, is there a way to back them up and restore them?

Before you install the new firmware, plug your Kobo into the USB and copy everything from the visible drive. Then you can install the new firmware.

I have both of those installed on my Libra Colour and the update did not seem to have any effect on either. I was prepared to do a re-install on both but does not seem to be needed.

Just for the record (since it's unlikely to affect anyone here): I have a Tolino Vision Color "migrated" to a Kobo Libra Colour. There were no problems until I installed this 4.45 update. No input was recognized anymore, and the device kept rebooting. Even resetting and reconfiguring did not help. The problem reappeared with the current version. So now I'm back on Tolino for the time being.

I cannot confirm this issue, no problems after updating my original Vision Color to Kobo 4.45.

Interesting. Do you also have a T106B model?
