Problems after update to 4.38.23038
My Clara 2E did an automatic update to version 4.38.23038. Since then, I have had a number of issues:
Won't connect to wifi. It has also lost the known connections. There is nothing wrong with the wifi - other devices are using it. Books sideloaded onto the 2E after the update are shown as "KOBO EPUB", previous ones just "EPUB". The page counts for these newly loaded books is more than 3 times higher than they should be. The book I am reading now shows 870 pages; the same book on a non-updated Kobo shows 278 pages. Has anyone else experienced any issues like these, and does anyone have any ideas to fix them? Is it possible to roll back an update? No, I didn't get a backup just before the update. Thanks for any information. |

Yes, rolling back is easy. Go here:
https://pgaskin.net/KoboStuff/kobofirmware.html and download the firmware file for your device. Copy KoboRoot.tgz to the .Kobo folder and then eject to perform a manual update to the firmware version of your choice. KEPUB uses 1 screen = 1 page, so it sounds like Kobo has either erroneously started treating EPUB files as KEPUB, or maybe Kobo is trying to unify the reading engines finally? What you're seeing is normal for KEPUB files but was not normal for EPUB, which should be using Adobe's synthetic page numbering system. |

How did you sideload the books? From Calibre?

If you are using the Kobo Touch Extended driver, open it's configuration dialog and on the fourth tab (Extended), remove the check mark from the Send books as kepub. Alternatively, switch to the Kobo Touch driver (make sure you transfer the setup) which does not do the on the fly conversion. |

Oh, I guess I misread the post as "existing sideloaded books now spontaneously have become KEPUB after the update", rather than new books being sideloaded after the update.

If the OP uses Calibre, then it's likely the Kobo driver settings there changed for some reason, as DNSB suggested. |

What I was looking at was the "Books sideloaded onto the 2E after the update are shown as "KOBO EPUB", previous ones just "EPUB"." in the original post. This suggested a change in calibre settings to me. Possibly a switch from using the KoboTouch driver to using the KoboTouchExtended driver or a configuration change in the driver.

Thanks for all the valuable feedback. It was a setting in the Kobo Touch extended driver that needed changing. I'd had to do a Calibre re-install about the same time as the Kobo update, and hadn't looked to see if anything had changed in the plugin settings. In fact, I didn't even know that the culprit setting existed.
Now to figure out why the wifi has become non-connectable! |
