Updating after that is cleaner, especially if you don't want to use the latest version.
Downgrading the firmware without doing this might have issues. Usually, going back one or two firmware versions is OK. But, there are some firmware versions that it won't work for. Because of some of the updates, it is possible that 4.30.18838 is one of them.
For calibre, if you have version 5.31 installed, you should be able to install 5.32. But, without knowing what the error was, it is impossible to say what happened. |
I did a factory reset from the developer menu, as you suggested.
The problems remain exactly as described above. Here is the error message once again (now on a freshly factory reset device, auto-updated immediately on first boot):
