Hello there..I want to roll back to flyme 5 as i have experienced a lot of problemin 6.
My problems are mainly with connectivity.
I have a vodafone 4g .
1.
Most of the time when i switch on mobile data network switches to 3g.
Even when the 4g network is full and 3g shows 3 or 4 bars.
2.
When i make a call if tge network is on 4g it doesn't switches to 3g or 2g in the 1st attempt or doesn't switches at all.
I have to go to settings and chose 2g only network.
What I have done.
1.
i have used engineering mode *#4636#*#* to force lte only network but still network switches to 3g.
2.
I just couldn't understand 2nd problem.

My expectations.
Please suggest a method so that network switches only between 4g(mobile data) and 2g (calling).
I dont want 3g network because its weak
Or suggest me details on how to rollback to 5 as the update file doesn't work on flyme 6
.
Thanks
