In this guide, we will show you the steps to unlock bootloader on Vivo iQOO 9/Pro devices. One of the relatively new entries in the Vivo family, this device boasts an impressive spec sheet. While it’s appreciated by all, what isn’t is the underlying OS skin. The device comes in two variants – Funtouch 12 (Global) and Origin OS Ocean (China). And it’s the last set of users who are having a hard time there.

There are many non-Chinese users who have acquired this device but are unable to use it effectively.
