vivo Y21s Overview
The vivo Y21s is an Android device from vivo, released in 2021. It combines the Mediatek MT6769V/CU Helio G80 (12 nm) and a 6.51-inch display, running Android 11. This page tracks its full specifications, root status, and the bootloader and recovery notes that apply to it.
Root the vivo Y21s
The vivo Y21s is a 2021 Android device from vivo. It runs the Mediatek MT6769V/CU Helio G80 (12 nm), a MediaTek platform, flashed via SP Flash Tool on many models with BROM as the deep-recovery path. Shipped software: Android 11, Funtouch 11.1. Because vivo does not currently provide a bootloader unlock for devices like this one, conventional Magisk root is not possible — contact us before assuming otherwise, as regional exceptions occasionally exist.
Difficulty
Restricted — official unlock unavailable
Typical time
N/A without an unlock path
Method
No conventional method — bootloader unlock unavailable
Bootloader unlock on vivo
vivo (and iQOO) do not offer a general official bootloader unlock outside limited regional programs, so most retail units cannot be conventionally rooted.
Platform notes
MediaTek platforms flash through SP Flash Tool rather than plain fastboot on many models, and expose BROM mode as a deep-recovery path. Correct scatter/firmware matching matters more here than on Snapdragon devices.
Before you start
- Bootloader unlocking factory-resets the device on almost all models — back up everything first.
FAQ
Can I root the vivo Y21s?
Not through any conventional method. vivo (and iQOO) do not offer a general official bootloader unlock outside limited regional programs, so most retail units cannot be conventionally rooted. Magisk requires an unlocked bootloader, so without an official unlock path the vivo Y21s cannot be rooted.
Will root the vivo Y21s void my warranty?
vivo will generally treat a rooted vivo Y21s as outside warranty while it is modified. Restoring full stock firmware before a service visit usually restores normal treatment in practice, and consumer law in some regions (such as the EU) may still cover defects unrelated to root.
What Android version does the vivo Y21s run?
It runs Android 11, Funtouch 11.1. The specifications table on this page lists the full software details.
