This is my device description: Model Name: ASUS X00LD Firmware Version: WW. 14.0400.1708.160-20170911 Rooted or not: no I tried to upgrade firmware using version WW-15.0400.1910.528 as provided on the web. I was downloaded it then copied to internal phone, but there is no reaction on system update detection such as icon notification on the drawer, even I restarted several times. What should I have to do? I want to upgrade Bluetooth version instead. And also to follow the android development until the latest firmware. Need solution... Please help me. Thanks
