Most Android OEMs allow an official bootloader unlock via fastboot oem unlock or an unlock token. vivo does not. For the 1610, there is no official unlock API, no "OEM Unlocking" toggle in Developer Options that actually works, and no unlock service from vivo. Document Version: 1
Before beginning, it is crucial to correctly identify your device. The model number vivo 1610 typically refers to the Vivo Y53. However, in some regions, similar model numbers are associated with the Vivo Y53i or Vivo Y69.
Why does this matter? Flashing a ROM designed for the wrong variant (e.g., installing a Y53 ROM on a Y69) will likely result in a hard brick (the phone will not turn on). Verify your exact model by going to Settings > About Phone > Model.
