Clara HD ClaraHD "Frozen" in a State yet working

[jfp555]

Hi all!

I've tried googling for a solution to this strange issue but it isn't easy to search for such an issue.

For quite some time now, my ClaraHD has been "stuck" in a state where it seems to be fully operational and even appears to allow new books to be sideloaded, but upon removal from the PC, the added books are nowhere to be found.

If the battery dies and I turn it back on, it "reverts" to an older state (probably where the issue began) and doesn't even update the "books being read currently" row on the home screen.

I can read the books already within it normally, but can't add any new ones. Can't seem to figure it out.

Is there any way I can perform a backup on my PC of the current state and then do a factory reset? Really would prefer if there was a simpler solution.

Thanks in advance!

That sounds as if either the database is corrupted though calibre should give you a message about that or the internal µSD card has exceeded it's write lifespan and is not in a read-only state.

If you have Kobo Utilities installed with calibre, you can use it's database check function otherwise, you can use pretty much any SQLite tool. Copy the KoboReader.sqlite database to your computer and run the database check on that file. I'm using SQLite Expert Personal since I was used to it from a couple of projects at work but there are several options. You can try copying the entire exposed partition to a directory on your computer and using Kobo Utilities to save the reading status (Store/restore reading positions => Store). After that, you can try the following in order:

1. Sign out to replace the database with a blank one (More => Accounts => Signout). This does not remove your sideloaded books and they will be imported but reading positions will be lost.
2. Factory reset to wipe the exposed partition but leaves the firmware alone. More => Settings => Device information => Factory reset your eReader. All your sideloaded books will be removed and will need to be restored from calibre.
3. This one assumes that you have done a search for devmodeon to enable Developer mode. Once that is done, More => Settings => Device Information => Developer options => Factory reset your eReader. This will wipe the user partition and restore the firmware to the factory firmware. As in variant 2, you will need to restore any sideloaded ebooks. Any patches and add-ons will be wiped. This is equivalent to the manual factory reset.

After any of these procedures, you can restore the reading positions using the Restore option in Kobo Utilities Store/restore reading positions.

Alternative is to copy the files/directories you copied back to your Kobo and doing a restart.

If the read-only state is the case, you can try removing the µSD card, creating an image and writing the image to a new µSD card. See the the Memory Upgrade Mod Guide (With Pictures) thread for some help with this.

Thank you so much for that. The database was corrupted. Thankfully I did have a backup for the db.

I copied the entire contents of the Kobo folder to my harddrive and did a factory reset.

The only thing that I cannot figure out is how to restore read positions in books.

I may not have backed that up (thinking it would be in the db?) so can you please tell me where in the Kobo folder it can be found so that I may restore it manually?

Once again, thank you for your quick and detailed response!

There is no way you can restore your reading positions unless you have been using Kobo Utilities to keep track of your reading positions and storing them in calibre with the books.

If you get stuck setting up storing your reading positions in calibre, ask for help in the Kobo Utilities thread at https://www.mobileread.com/forums/sh...d.php?t=366110

Thank you for clearing that up. I'm really happy to have the ereader back up and running. Loss of reading positions isn't that big of a deal as I was only reading 4 books concurrently and can reset them manually.
