• Don't use ADB Sideloadput it in a SD card and update it from there by going to "Recovery Mode > update from sd card"
• Update only if you already have the September 2017 update installed. This is not guaranteed to run on older updates. Also, this is only tested for Southeast Asian region. probably it might work on other regions but don't take my word on it.
