if yours Mini is G version and you live in europe - then yes.
Sorry if I'm hijacking this thread, if so, I can start another.
I recently purchased this phone (B2017G) from Gearbest as well.
It is still on 6.0.1 Marshmallow.
I have been searching for the right update file, starting with the US version, since that is where I live, but no go. The bootloader says
"E footer is wrong
"E:signature verification failed
"E: open file /cache/fota/error_code error erno = 2
'Installation aborted'
Am I right in thinking I need to find the update with the right signature? I have tried US, Austrian and Russian official ZTE updates with no success so far.. Am I on the right track?
US ZTE Support was as helpful as they could be, but were not familiar with the GearBest global variant. They sent me to the global support site, which won't let me use it, since I'm from the US, lol
Any suggestions? I'm going to try the German update from earlier in this thread after I get home tonight, by the way...
