Because it has entered a state where it freezes several times a day and I have to restart it—or it restarts on its own—I’ve tried several strategies that so far haven’t worked:
- I reinstalled firmware 4.38.23171
- I downgraded to Calibre 7.26
- Factory reset and then returned to Calibre 8
- Uninstalled NickelMenu
- Installed the second-to-last firmware version: kobo-update-4.38.23038
It still keeps freezing/restarting.
What else can I try? Do I really have to resort—though I’d rather not—to replacing the SD card?
