Be Aware of VIVO MTK Devices: April 2024 Protections and the Latest Updates

As of April 2024, VIVO MTK devices have received significant security updates that users and repair technicians need to be aware of. These new protections impact various tools and methods commonly used for unlocking, repairing, and downgrading devices. This article will provide an overview of these changes and highlight specific VIVO models affected by the updates.

New Protections Post-April 2024 – VIVO MTK Devices

The recent updates have introduced robust security measures, making it increasingly difficult to bypass or downgrade devices using traditional tools such as USB, Pandora, and Unlock Tool. Key changes include:

Anti-Rollback Protection

One of the most significant changes is the activation of anti-rollback protection on several VIVO devices. This feature, often referred to as “FUSED,” prevents the device from being downgraded to a previous firmware version. If an attempt is made to roll back the firmware, the device will detect this and may become inoperable, requiring intervention via ISP (In-System Programming).

ISP Device Interventions

Even with ISP devices, caution is required. The new protections mean that even if you manage to bypass initial security measures, the device will eventually fail if the firmware is not matched correctly. Specifically, you will need to ensure that the preloader, boot1, and lu0 are written with the same protection version as the device’s current firmware to avoid bricking the device.
