• Hardware-level attacks: e.g., JTAG, UART access, Chip-off, or SPI flash rewriting on removed/serviced NAND/EEPROM — requires advanced hardware skills and risks bricking.
• Re-signing via leaked keys: historical incidents where manufacturers’ private keys leaked, enabling custom images (rare and illegal).
• Chain-of-trust bypasses through vulnerable components: using exploitable peripherals or drivers to bypass version checks.
