MacOS 10.13, Calibre, & Kobo firmware version

Hi,

- I have an iMac Mid-2011 so the latest version of MacOS that I can have is 10.13 (MacOS High Sierra). I have this version installed with latest updates.

- According to Calibre website, the latest version for MacOS older than 10.14 (Mojave) is 3.48. I have this installed as well.

- My Kobo Aura H2O has version 4.19.14123 (12/10/19) firmware installed.

My Kobo has been playing well with Calibre for years, but lately, I have been getting the following error from Calibre

"Kobo database version unsupported - See details"

The details screen from Calibre says that this is due to the Kobo's firmware/database version.

Then, just a few days ago, Calibre gives the following when I send a book to my Kobo:

"Error communicating with device"

I searched the forums and saw several advice saying that this error indicates a corrupted Kobo database and that the solution is to log out / log in to Kobo and this will rebuild the Kobo database. I did this, and saw that the Kobo went thru the database rebuild process. But instead of fixing it, it seems to have made the problem worse. Now, I see weird things in my list of books (weird "book names" that seem to be part of the software, like: appbar.align.auto, appbar.align.center, etc.), and most of my Collections now have zero books.

** I am willing to reset my Kobo to factory settings. **

Can someone please help me out with the following:

1) What is the latest stable Kobo firmware version that will work with Calibre 3.48. Right now, I have 4.19.14123 and it is likely that I will need an older firmware version.

2) My expectation is that when I reset the Kobo to factory setting, and I then enable WIFI, the Kobo will automatically upgrade the firmware. How do I "stop" the Kobo from updating to the latest firmware so that I update only to what works with Calibre 3.48?

3) I use Pocket a LOT, and so I would like the WIFI to be on. How do I tell Kobo to sync Pocket BUT NOT the firmware?

TIA,

Jay
