My fujifilm XT2 has the firmware 1.35 version, and I couldn't update it to any firmware of the XT2 firmware listed in the fujifilm website.
I've tried multiple times as well as downloading in diff regions too... Still having the same error "This firmware is not for this model"
though I'm 100% sure that I did the same procedure of firmware updating.
This is the first time I encounter this...
BTW... I have XE1/Pro1/XH1/XT3/XT2 only this XT2 with this firmware ver 1.35 has this issue,
.. I just recently acquired this camera and based on my research, this is a pre production beta firmware.
