Hey guys i have a samsung galaxy s4 on android 4.4.2 kitkat and i am not happy at all with the kitkat update since it has ruined battery life and is causing many other problems like lag and overheating
So i want to downgrade to the stock 4.2.2. I have never rooted my samsung galaxy s4 and i am still unrooted.
I know knox will be set to 0x1 after downgrading but i do not care about it as triangle away supports galaxy s4 now .
So here is what i want to know
If i download the proper 4.2.2 firmware from sammobile according to my country(India) and install it via odin then will the process work? and if it is the right procedure does it require root ?
Is there any chance that my phone can get bricked because of knox ?
and how should i take backup of efs in case of a possible imei error ?
