Kobo Aura One reboots when deleting epubs
I've done some searching and haven't found anything - hopefully one of you can help me.
Sometime in the last few months my Kobo Aura One started rebooting when I tried to delete an epub. It happens every time I try to delete a file - the Kobo reboots and the file never gets deleted. I can remove the files from the device when it's connected by USB, but they still show up under My Books. I dealt with the problem for a while, figuring I just needed a factory reset, but I did the factory reset a few days ago, loaded up some books, tried to delete one, and it rebooted again. I load books with Calibre and they're mostly non-DRM epub files. |

I have the same problem with the KA1 LE. I have been told that it is because of a "scrambled" database; NOT TRUE.
I have factory reset the KA1 LE & the 'removed' books remain. However, after reloading the books from Calibre, I side-loaded some Light Novels from my computer. Interesting that a "removed" book from the side-loaded books shows up even tho the book does not show up in the author sort, only in the 'books' sorted list. Same problem with a book loaded from Calibre. Looks to me the sqlite is not getting deleted when doing a factory reset. Can I delete the sqlite using my pc before doing a factory reset? Buggy book management and/or "factory reset". On top of which, after I do a "factory reset" & KA1 LE is ready, I get a popup that say my Overdrive book has expired. The library book was returned many days past so where is the msg coming from??? Methinks the database still thinks that I have the library book even tho the books was checked out using my galaxy tab pro! Probably an Overdrive sync problem. |

Whenever I've done a factory reset, any books on the internal storage, which is all the KA1 has, have been deleted and the database has no books imported. |

I agree with David. For some reason you're not accomplishing a true factory reset from what you're describing. A reboot reset maybe, but not a full reset.
And signing out of your Kobo account on your device and signing back in should also reset the database. |

After the fake GUI factory reset, I still have to go thru the setup like after unboxing with selecting the language, getting wifi setup, logging to the account, waiting for firmware updating, seeing a dialog about searching wifi network to join(?) then some other stuff & a dialogue claiming my Overdrive book has expired. The part about Overdrive book expiring is different from after unboxing as I think that the msg was that the library will expire in 2 days. So is it "safe" to delete the SQLite before doing the factory reset? Also saw 2 sqlites in .kobo, koreader & book; the book.sqlite is much smaller than the koreader.lite which I think is for all the books? Don't remember if stated, but the "removed" book were removed prior to doing the factory reset. The side-load of books did not include the "removed book" which makes it curious where the ghost book came from and/or that the sqlite did not get reestablished with the re-loading of the books after the "factory reset". |

Also, the question is asked because we have plenty of people report doing a factory reset and then when questioned, it turns out they just pressed the pinhole reset button. There is enough uncertainty, and your experience is unusual enough, to want to check exactly what you did. Quote:

When you have had this problem, have you connected to the PC and checked if the file was there or not? I'm also not sure whether you are saying the book never disappears from the library list, or that it disappears by comes back later. I also don't remember if you said before what happens if you delete the book using calibre, or simply delete the book from the device when it is connected to the PC. The behaviour when doing these things might give a clue as to what is going on. |

When I do a "factory reset", the files are not there as KA1 LE says that there are not any books, which is true. I have not backed up anything to the cloud as I will not be using the cloud. The reset is supposed to give me a virgin reader.
I did a manual factory reset as per the user guide & the problem book still comes up; & this time one of the light novel books did not show up on the book list but is seen using the usb connection & file explorer! Doing the KA1 remove just reboots; the book never disappear. Do not know how the book resurrects after a reset since it is not loaded. I never use Calibre to delete a book from the device nor do I delete a book from the device when connected to Calibre. I found a problem in that it KA1 changes or truncates the title if it is considered "too long"; the database setup get confused or mangled. e.g. "Risou no Himo Seikatsu Volume 05.epub" is listed on the KA1 as "Risou no Himo Seikatsu V05" in the book list. but "Risou no Himo Seikatsu Volume 06.epub" got listed as "Risou no Himo Seikatsu Volume 05.epub" For "13 Mahouka Koukou no Rettousei #13 - Steeplechase Chapter (B-T)(Roah)-v2.epub", KA1 book list truncates to Mahouka Koukou no Rettousei #13.epub" Looks to me like KA1 has a limitation on file name size. Will have to do another factory reset & not load my light novels as the KA1 is unable deal with long file names like an Android tablet. Or perhaps it is just the nickel app. There is a bug with the forums as if one takes too long entering a reply, one is evidently logged out as the msg say I am not authorized to enter a reply or anything. I forgot to set the login to do the "remember me" thing. |

However what your Kobo uses in the book list is not related to the filename. It is derived from the metadata embedded in the epub file you are transferring over to your device. The 240 character filename file that I transferred over was correctly named Out of the Vortex with the author name showing as Steve White and the series showing as Her Majesty’s American 1.5 (the series took a second connection to update the metadata after the book had been imported into the database) in My Books. Check out calibre for correcting metadata along with either Sigil or calibre's editor using Flightcrew (Sigil, epub2) or epubcheck (Sigil, calibre editor, epub2 or epub3) to locate and correct errors in the structure and content of your ebooks before sending ebooks to your Kobo. Or even use the QualityCheck plugin for calibre to do some basic checks. Last edited by DNSB; 08-28-2018 at 12:15 AM. |

Calibre will massage the file names and paths to keep well within this limit. This is taking into account the directories in use, so it can give much shorter file names. But, that does not affect the metadata within the book. The file name massaging that calibre does is to also remove characters that might be a problem. It will replace these with an underscore. The "#" in the above file name makes me uncomfortable, so I have just done a test on my Glo HD to check it is handled properly. Quote:
The only thing I can think to suggest at this point is to format the book partition using Windows. This would normally be something I would never suggest, but it might work. Connect the device, and format the partition that is presented to the PC. The format needs to be FAT32 and use all the available space. Do a full format, not a quick format. When that is done, eject the device. It will then take you through the setup. After that, sideload a book and see what happens when you delete it. If, after that, it still isn't working, then I think it is warranty replacement time. The last thought is that the storage is failing and needs to be fixed. And that can only be done by replacing the device. Hopefully it is still covered. |

It's been ages since I tried this, but some strange things do happen when that books path length is to long. And it is because the path for the cover images is to long. I don't remember exactly what happened and would need to experiment. |

If it was borrowed on the Aura One, I wonder if it has to do with the fact that when a library book gets returned, a preview of the same book automatically replaces the returned book. Maybe all this is irrelevant, but if the book you are trying to delete was a previously borrowed book, it could be why it's popping back on a "virgin" ereader (and why it's linked to your account in a way that isn't typical of your calibre based epub-library). Just thought it might be worth asking, as none of the people working to solve this with you mentioned overdrive. Probably not important. |

1. The Overdrive book was borrowed with another device, a tablet. I think that the library card id is synced with my devices that use the same library card.
2. The offending book is NOT in Calibre. The book was just copied to the KA1 using win10's file explorer. The real file names were not munged on the KA1, so the problem is the database extract of the metadata. I am not about to edit the metadata as they are light novels on the web; nor am I going to tell/post that the translators did a bad job as there are no problems with the books on my android tablets using moon+reader pro. 3. Just did a delete of the ".kobo" directory & went thru the mini(?) setup. The offending book remain in the book list! 4. Instead of immediately deleting the book, I just tried to read the book & the book came up; checked the number of pages & find that it is about right. Now, the embarrassing part is that it looks like the metadata did not get changed when the subsequent chapters were added using an online merge so that the title that included the word "incomplete" remained to muddle my mind! Calibre Companion on the tablets do not have any meta data problems nor any problem with my Boox C67ML e-ink reader. 5. Mystery partially solved! What remains now is the rebooting of the KA1 when deleting/removing a book which doesn't get removed but comes up with "not authorized to read DRM" on a book that does not have DRM. |

And something that I've completely forgotten to ask about, is are there any stack logs in the .kobo directory? These have the name "stack_0n.log" (n is a number) and can be produced when there is an error like you describe. If there are any, it can give a clue as to exactly where the error is. And an even dumber sounding question is, how big are these books? Most importantly, how many chapters do they have? I've just realised that the "light novels" you are talking about could be getting long. There is a chance that the delete is triggering a sickel reboot. If the behaviour when this happens is that you start the delete, it sits there for about 60 seconds, the light goes off and then the reboot happens, it might be sickel triggering a reboot because something seems to be hung. And if it is, then it explains the rest of the behaviour. Which leads to another question: Is it all books? Is it just these light novels or everything? Maybe we should do a controlled test. Grab an epub from the MR library here, sideload that and then delete it. These books are generally in good condition and have no errors. If it happens, others can test with the same book. If it doesn't, then it suggests an issue with your books. Last edited by davidfor; 08-28-2018 at 08:16 PM. |

1. After deleting the .kobo directory, ALL the book files remain, both the sideloaded & from Calibre. Looks like the designed got changed; I did the delete of .kobo after seeing a msg in another thread that the books remained.
2. Your suggestion getting a book from the MR library is good. Did that & the book delete does the same thing, reboot & the get a DRM msg when trying to read it after the delete. The book is " he Book of Snobs - William Makepeace Thackery.epub". My placing the book in the same subdirectory as the light novels "should not matter"? 3. The stack_00.log: Spoiler:
