The VX420-G2h v1 (RouterBOARD 420 series) is an end-of-life (EOL) product using the AR2317 MIPS-BE (Big Endian) architecture. The latest stable firmware for this platform is RouterOS v6.48.6. Do not attempt to install v7.x or v6.49.x, as these releases dropped support for MIPS-BE single-core devices. Technical Documentation: VX420-G2h v1 Firmware 1. Platform Overview The VX420-G2h v1 utilizes the RouterBOARD 420 platform. It is powered by an Atheros AR2317 System-on-Chip (SoC) running at 400 MHz. This is a MIPS-BE (Big Endian) architecture with 32 MB of onboard RAM and 64 MB of NAND storage. vx420-g2h v1 firmware
