Nokia Online Update Tool v6.2.8

Table of Contents

Online Service Tool (or OST) is the official software which is used to flash stock firmware on Nokia smartphones. The software is used by the FIH factory and Nokia Mobile Care to revert the phones to factory software in case of any issues.

OST requires stock firmware in the .nb0 format. That said, you can also flash an unpacked nb0 using OST LA if the .mfl file is correctly formatted. All required drivers are included with OST.

Official version of OST requires an account with a valid username and password to flash the phones. Only the authorized PC (using MAC address) can login to the account and service the smartphones. This is set to prevent unauthorized use of the software. The OST 6.0.4 shared in this post is a patched version which can be used without a login. Newer versions of OST exist, but they cannot be patched (yet).
