Obtain the Nokia Spd Unlock Tool V1.0 and install the necessary SPD USB Drivers on your PC.
Use only on devices you own or have explicit permission to service. Unlocking or modifying devices may violate carrier terms or local laws.
The v1.0 tool is relatively safe compared to later flashing tools. It primarily reads and writes to a specific memory region (the NVRAM block) without touching the bootloader. However, a power failure during the process could brick a legacy device.
While holding the button, connect the phone to your PC via USB.
