Unofficial Bootloader Unlock for HMD Nokia Phones

the_laser, Leader of SETool has released the very first unofficial bootloader unlock method for HMD Nokia phones.
With the basis he made, we eventually expanded the availability of bootloader unlock to more models.

After HMD terminated contract with FIH Mobile for smartphones manufacturing, it had decided to cooperate with various of ODMs.

Permanently Free Bootloader Unlock for legacy models

After the development of our own service tool, we decided to make Bootloader Unlock for previously released models for free of charge.

We believe either HMD Global Oy or FIH Mobile no longer care them, and less and less users are still using them. Besides, we want to give something back to the open source community such as Lineage OS, Postmarket OS.
