At this time, Kobo is starting to roll out firmware 4.38.23648 for the Libra 2. It shows as available for the Libra 2 on Patrick Gaskin's Kobo Firmware Downloads

The two items I show for the update are:

Has anyone applied this firmware to your Libra 2?

DNSB · 03-26-2026, 05:38 PM

At least two people that I know of. Both report the Kobo Remote is much improved with this firmware.

Downloading it as we speak. I got one during the saw last month. I don't use the Kobo Remote with it, since it has buttons.

The connection with the Kobo Remote is greatly improved. The bleu light on the back of the remote doesn't blink, so the connection is stable.

Enabling Bluetooth still also enables Wifi.

I'm interested to know if stability with non-Kobo Remotes (e.g., the 8BitDo) is also improved.

The best way to find out is to try it.

As Jon said, the best way to experiment and see if your non-Kobo remote is more stable. OTOH, since it is not a Kobo device, to me, it's a coin toss.

My 8bitdo Micro was never unstable with my Libra 2. The issue was the wifi turning on with the bluetooth and the need to re-pair the 8bitdo every time I used it. The wifi problem, Kobo fixed it with the previous update. After this update, the 8bitdo still needs to be in pairing mode to connect, and I stll need to manually connect. The Libra 2 does not save the the device either, unlike my Clara BW. However, once connected, the 8bitdo works just fine.

I have installed it on my Libra 2.
Connection to the Kobo remote is indeed stable now, it just keeps working and registers all button presses.
Battery drain still seems to be there though.

I can't live without the both page turn buttons go next patch, so until someone smarter than me makes it work with this software, I need to skip it. Don't have a remote anyway. ��

You can live without the Both page turn buttons go next patch. Not having won't kill you.

Well, I'm not surprised about the still existing battery issue, kobo devices have really poor power management, especially when it comes to radio. Bluetooth on the other hand should have LE, but who knows.
The only thing I envy from kindles is this, both hardware and software power optimizations.

Responding to a PM asking about the availability of 4.38.23648 for other Kobo devices.

If you look at the links on Patrick Gaskin's Kobo Firmware Downloads page, you will notice the major difference between any of the links is the hardware generation section.

For example, https://ereaderfiles.kobo.com/firmwa...4.38.23648.zip is the link for the Libra 2 firmware.

If you modify the kobo9 to kobo3 through kobo11, you will download the firmware for that hardware generation, that is for the original question, to download this firmware for the Kobo Elipsa 2E, you would use kobo11.
