Amazon Firestick help!!! Kodi Updates

Having such a difficult time with Kodi on my Firestick….grrrr!!!!
I am in no way a coder, so most of the verbiage is foreign to me and could really really really use some help.

Numerous times I’ve had to uninstall Jarvis because it froze up (I really like Royalist ;-( come back!), then installed the latest versions to no avail. And can’t seem to retrieve my backup or keep any settings.

How do I update Kodi WITHOUT losing my settings? (for some reason it will not connect back to the internet after updating) grrrrr!!!!!

Help!
