1. Understanding the Hardware: QM215 + eMMC

QM215 is a 64-bit Cortex-A53 quad-core SoC designed for Android Go.
eMMC (embedded MultiMediaCard) is the non-volatile storage soldered onto the PCB.
Hard resets in such devices work by erasing user data partitions (userdata, cache, misc) while keeping the bootloader and system partitions intact, unless a full flash is performed.
