Hi, I have TP-Link TL-WR741ND.
About 1 years ago I installed Gargoyle firmware (modified OpenWrt 12.09) using OEM firmware using original TP-Link webui.

Now I would like to install OpenWrt (no Gargoyle) 14.09. Is possible to install new system from existing OpenWrt (I have root SSH access).
I found only Syupgrade which use xxx-sysupgrade.bin image.
But OEM firmware use xxx-factory.bin. Is there any difference?

I do not have serial port access yet. I do not want open my router.

Is possible to use mtd?

# cd /tmp 
# wget  http://downloads.openwrt.org/barrier_breaker/14.07/ar71xx/generic/openwrt-ar71xx-generic-tl-wr741nd-v4-squashfs-factory.bin
# mtd -r write /tmp/openwrt-ar71xx-generic-tl-wr741nd-v4-squashfs-factory.bin firmware

How can I reinstall my router?

sysupgrade is fine since you already did the initial "factory" flash with gargoyle (which is still openwrt). Careful, only 4MB of flash on this device.
