Vivo/IQOO#
- Verdict: 馃崊 Terrible!
The BBK* family has an unlocking problem. If in case of OPPO/Realme they at least offer an app in some regions, Vivo is locked completely.
Well, that is, if xdaforums.com doesn't apply to you.
On pre-May 2022 firmware. I believe these methods were ~universal, but proceed with caution:
- Vivo x70 Pro+: xdaforums.com
- Vivo Y31 2021: xdaforums.com
There is also a chance that your device is vulnerable to one of the MTK or Unisoc exploits.
Magisk#
Vivo devices have kernel-level patches to block the su binary, so to use Magisk you should flash this modified version with suu. This only applies on devices which run Funtouch, for devices which run OriginOS (mainly their Chinese market devices), while the bootloader is still not unlockable, su is not blocked.
* BBK Electronics was deregistered as a company on 7 April 2023.
