So this is pretty interesting.
I was on B817 rooted and twrp latest version by Araca.
Now i flashed the b817 recovery again and flashed B800 by 3 button method, after this i was on b800 and root survived and still got all apps and data. I am going to b609 with 3 button method lets see what the result will be
Maybe if you downgrade with from same version of android you'll keep all your stuff... Dont know how huawei works with this.
