Problem to rebuild a Kobo database
I came across a serious problem which necessitated a logout from my account on my Kobo Glo reader to rebuild the database. For an unknown reason, the logout procedure ends without effect, that is I am unable to logout. I tried a factory reset and completed the procedure but the database wasn't rebuilt and I wasn't logout either.
Here is what I intend to do:
Do you think I can do that safely? Do you see any other procedure I could use to solve this problem? |

If you are discussing removing the KoboReader.sqlite file from inside the .kobo directory? I've never bothered to do that since the logout/login or factory reset both give you a clean database. I suspect that if you are seeing issues that are not cleared by the factory reset, you may have an issue with your internal uSD card. There are several threads you may find useful (search is your buddy). The two I would recommend would be the Memory Upgrade Mod Guide (With Pictures) thread and the Kobo Glo: Need SD card image thread. Did you try the Kobo Glo manual factory reset procedure?
Good luck! Last edited by DNSB; 11-21-2018 at 04:24 PM. |

are you sure you did a factory reset?
nothing should survive. after factory reset it should not even know which language you want to be using, so language selection screen is the first thing that shows up. then it would download firmware update as that is gone too. either you're doing something wrong (not actually factory resetting) or ... your data survives factory reset somehow? In theory it would be possible for a mod to break factory reset. Or it could be bad SD card that no longer accepts writes so old data is there to stay forever? but then you could not copy new books to the device either |

And for the record, it is usually a good idea to detail what the original problem is that you are trying to solve. If we knew what the original "serious problem" was, maybe our suggestions would be different. |

The first thing I noticed was a book sent to the device wasn't green checked on Calibre on a second (USB) connection. The book was on the device in a appropriate directory. I deleted manually this book on the device (probably my mistake) and sent another book with the same effect. I then suspected one particular book I had sent previously and deleted it from the device with Calibre. I changed its authors name (leaving a dot out) and resent it. But on the following reconnections, Calibre showed the book on the SD Card as FILE MISSING:<old name of the book>.I tried to delete it with Calibre (and refreshed the metadata) to no avail. I tried to harmonize it with the library with the same end result. In between I tried different backups of the database, always showing at the end the FILE MISSING:<> message. Basically I can add book with Calibre but they don't show up on the device. I can't mark any book as "read". I hope I don't forget anything, but I'm on this problem for a few days now and so much happened I wouldn't be surprised I missed something. Last edited by bernard.ryefield; 11-21-2018 at 06:52 PM. |

Did you check the firmware version on the device afterwards? If it didn't go back to an older one, then the factory reset probably didn't actually happen. A failing SD card is the most likely reason for that.

The process is fairly simple. I have done it on a Glo recently. The most complicated part was actually opening the device. I can never remember which corner is the best spot to start. Other than that, you need a PC with a SD card slot or an appropriate adapter.

Glo problem with database
Now it's getting weirder:
I followed the steps I described in my original post and I deleted also the BookReader.sqlite file and the fonts directory. I did the (failed) factory reset (I wasn't asked to select a language). After sync with the Kobo Desktop and ejection I find the same files and directory I deleted. Apparently there is a copy somewhere which is restored when the factory reset is done.

You could try formatting the books partition from Windows. I have done this in the past and it worked, but I don't know if it will be any different to what you are seeing. And if it does help, it is probably just putting off the inevitable. The card really needs to be replaced. |

No. He means the volume that gets mounted on your PC when you connect via USB.

By the way I noticed a strange thing: after the last FW update, the MAC address has changed. I noticed it after I couldn't connect by wi-fi as I put a white list filtering the MAC addresses on my wi-fi hot-spot. I put the new MAC address in the white list but couldn't connect either. |
