#1710 Cannot connect Jolla phone (2931:0a07) on Fedora 25/26
Fedora 26 unfortunately still ships libmtp 1.1.11 but as
https://sourceforge.net/p/libmtp/bugs/1613/ is about 05c6:0a07 and in my case it is 2931:0a07, I'd assume that even running 1.1.13 or newer would not fix this:

the id is listed in 1.1.12 and 1.1.13 ... should work if you add the id to the hwdb files or udev rules depending what fedora uses.
thanks for the report!
