ill just need kies to install it? do i need to back up sir? or is there any posibilities that i brick my phone? thanks
You can backup (the data) if you want.
Flash the stock firmware using Kies won't brick your device.
im already using lte/wcdma/gsm in my settings but the only signal it gives is E, but when i try my simcard to other device it can give H signal. is it a hardware problem? or software?
do i need to download the file first sir? then ill use kies? thanks
