TL-WR740N v5: OpenWrt 24.10 on 4 MB Without a Serial Cable
Reading TP-Link’s U-Boot TFTP recovery from a flash dump, fitting OpenWrt 24.10 with Wi-Fi into 4 MB, testing it in QEMU first, adding a tiny web UI without LuCI, getting back in through failsafe when the first flash came up with a dead LAN, and finally running the TFTP recovery for real.
