Nia KOReader didn't boot start anymore after battery has depleted

yang · 02-23-2026, 08:03 PM

Hello,

I have a Kobo Nia reader. Some years ago, I made/had a working installation of KOReader on it. I didn't use the device more than a year and the battery has depleted. I was able to fully recharge it, however when I booted/started the Nia again for the first time, it went through an upgrade process with the default Kobo firmware. Now I have a new default installation of Kobo firmware, without any e-books in it. I am interested if it's somehow possible to revive previous installation of KOReader, where I had e-books added to the device, and later perform the KOReader upgrade? Or is it wiped out and lost, and therefore better to start a brand new installation of KOReader? I also do not see any SD card port on the device, where I could store the e-books, which wouldn't get erased on depletion.

From your description, it sounds as if your Nia did a factory reset so you will have to re-install KOReader.

I'd suggest using the packages in the [color=blue]One-Click Install Packages for KOReader & Plato[/blue] thread's first message and the install scripts in the second message.
