#!/usr/bin/env bash
# Flash stock OpenWrt on a GL.iNet GL-MT3000 (Beryl AX) via SSH from archy
#
# Usage: ./flash-mt3000-openwrt.sh <router-password> [router-ip]
#
# Defaults to 192.168.8.1. Runs entirely from archy (archipelago).
# Requires: curl, sshpass, ssh, sha256sum, scp
#
# What it does:
# 1. Verifies tools and connectivity
# 2. Downloads the stock OpenWrt sysupgrade image
# 3. Verifies SHA256 checksum
# 4. Uploads image to the router via SCP
# 5. Flashes via sysupgrade (no settings preserved)
# 6. Waits for reboot and verifies new firmware
#
# After flash, stock OpenWrt is at 192.168.1.1 (root, no password).
