* OpenWRT Firmware for AC Series of Routers: https://downloads.openwrt.org/releases/19.07.3/targets/mvebu/cortexa9/ | |||
* OpenWRT De-Bricking Information: [OpenWrt Wiki] Linksys WRT AC Series | |||
** run nandboot (script for booting the router from the MTD5 Partition) | |||
** run altnandboot (script for booting the router from the MTD7 Partition, AKA the 'alternate') | |||
** GOTCHA!: One really big "gotcha" from using the above commands relates to upgrading firmware. When booting using the altnandboot script from above, when flashing a new image it will flash it to the current partition. This is counter to the usual behavior where OpenWRT will flash a new image to the ''other'' parition. | |||
* A Recommendation: Configure the MTD6 Partition as the primary partition that boots the /overlay, and leave the secondary MTD8 partition configured to NOT boot an overlay. This allows the MTD8 partition to function without a USB flash drive | |||

===Flashing Firmware=== | |||
Even though this article is about "de bricking" a router, it is also the fastest way to install firmware on ''both'' partitions of any WRT / AC Series router from the stock Linksys firmware. But it does require having console access to the router via a Serial / TTL cable. | Even though this article is about "de bricking" a router, it is also the fastest way to install firmware on ''both'' partitions of any WRT / AC Series router from the stock Linksys firmware.

It cannot be an coincidence that the WRT32X, black in color with a code name of "Venom" and a SoC from Marvell, isn't somehow named after the 2018 Marvel movie, Venom. | It cannot be an coincidence that the WRT32X, black in color with a code name of "Venom" and a SoC from Marvell, isn't somehow named after the 2018 Marvel movie, Venom. | ||
