Root the vivo S1 (China)
The vivo S1 (China) is a 2019 Android device from vivo. It runs the Mediatek MT6771 Helio P70 (12 nm), a MediaTek platform, flashed via SP Flash Tool on many models with BROM as the deep-recovery path. Shipped software: Android 9.0 (Pie), Funtouch 9. 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.
