For those of you who have been waiting for the marshmallow update on the SM-G900H, now is the time to update your firmware. This is the official Android 6.0 marshmallow update from Samsung.
You can install this ROM by using Odin and flashing it using Windows computer. If you want to install this update I highly recommend you to do a factory reset otherwise the stock firmware may run slow.
This is the exact same update you would find by using OTA(Over-The-Air). For those of you coming from a rooted S5 with custom ROM, flashing this stock firmware will unroot your device completely back to stock.
This is for Kazakhstan (SKZ) SM-G900H but you can also install it on any models with SM-G900H. If you do that, it WILL change your country code to Kazakhstan, which shouldn’t be a problem unless you are using any apps that require certain country code. (In most scenarios, you should be fine and you can always re-install the correct country firmware over later down the line when it is available.)
