Not listed

High brick risk. A bad flash, unlock, or downgrade can permanently disable the device. Read the specialist guide for this exact model and firmware before you touch it.

How-to

How to

Run the model-specific amonet unlock (MediaTek bootrom/preloader + LittleKernel exploit) from a Linux PC (some models also Windows) to get hacked fastboot and TWRP, then flash Magisk from TWRP. Some firmware versions require a temporary brick/downgrade step.

Follow the specialist sources linked on this page. If this path is a jailbreak, unlock, or flash, the specialist wiki is the how-to — we do not copy those steps here.

Notes

Some later units have a hardware change that blocks bootrom access.
