warranty
The warranty does not include software it's hardware only otherwise You could never update it , You simply lose then Your warranty at that point. And even if You manadged to get someone to give You a software related issue to the warranty exchange then it only means that You were treated with the at most respwct and that is their store policy, but internationaly warranties does nit work like that.oh man, too good to be true
I tried it as well but it does not save any changes to the file
so I guess there is no other possibility than to unlock the bootloader and then root the device - and lose the warranty
