Do you have a spare Micro SD Card? You could move the back to the SD card (via pulley menu in backup program), then remove the SD card , doublecheck on a PC if backup has been copied correctly moved to SD before performing a factory reset to be safe.
If no SD Card is available, you could try to install File Explorer and FTP Server on your Jolla.
File explorer (from Jolla store) to move the backup to wherever you can download the backup via FTP Server. (on any PC Firefox browser + FireFTP addon will do nicely as FTP client)
For FTP Server application you will first need to install Warehouse Openrepos client software first on your Jolla. You can Duckduckgo or Google "Warehouse Openrepos" in your Sailfish browser to find the link to where to download the installation file.
Install via File explorer.
This written with easy way to factory reset in mind.
That said, Is being stuck on clean and functional 1.1.7.28 such a bad thing? ;)
Please give a pointer if you are getting any errors when trying to update. With the information you are providing there's a lot of guessing to be made such as:
are you perhaps getting an error message "Could not determine the size of update"? Since there's been sightings of similar problem, although seems to mostly been when upgrading from 1.1.9.28 to 2.0.0.10.
Or what about the problem with the developer mode. Getting an error message "Problem with Store: Could not install jolla-developer-mode"?
Or something else perhaps?
Here's one discussion that might have something to do with you also.

If i try to enable developer mode the only reaction is an animated bar which never stops....
Another hint: i cannot add another account - the error message says something about an SSL-error and I should check if date and time are correct - which are.

You've been waiting how long/long enough for the developer mode to be enabled? For me it takes maybe 2-4 minutes to display a message of the problem that the developer mode can't be nstalled.
