What is Nokia Online Service Tool?
Nokia Online Service Tool is a firmware flashing software developed by HMD Global for their Android-based phones. It is used by the manufacturer internally or in service centers, to restore stock/factory software in case of any issues. The tool is often abbreviated as “Nokia OST LA“.
The tool supports stock firmware in .nb0 format. There is also a newer version (Nokia OST LA 6.1.2) available that supports the newer Oreo/Pie firmware, but it could not be patched yet.

We will soon be covering a tutorial on how to do that.
The official version of the tool is available online, but it could only be used with a valid username and password, something that only the official Nokia service center representatives have. In order for an average user to use the tool to flash stock firmware, it must first be patched.
