- No more (META/ATE/Preloader/BootROM) on VIVO MTK Devices.
- About Android (September 2022) patch level on VIVO devices.
Even (MT6762/MT6765) now can't be serviced via preloader mode (not even Read Info).
- In this patch, the PL_DA signature were (patched/changed) in preloader code and preloader mode now requires server authorization.
- we all know BootROM by DA exception disabled in (April 2022) patch, and test point blocked on the last month patch (August 2022).
- Now with (September 2022) OTA, they disable unauthorized preloader boot (the public Download Agent for MT6765 which works in preloader mode will not work anymore, and will send (0x7024) response (EPP signature mismatched)).
Devices that have been confirmed and affected by the update :
- VIVO Y12 PD1904

The updates are SoC based, so all (MT6762/5) will follow.
The update still beta, so it will be applied on all (MT6762/5) devices in the upcoming days, to test the new update, you need to download the beta version from settings.
