* Loco: Firmware Version: XW.v6.1.3 *
Sounds like we'd use the Loco XW LibreMesh firmware, but I'm worried
about the warning on the OpenWrt wiki:
https://openwrt.org/toh/ubiquiti/airmaxm
Special Firmware Note: AirOS XM.v5.5.X images used U-Boot 1.1.4.2-s594
(Dec 5 2012 - 15:23:07). The OpenWRT image can be successfully flashed
onto these versions of firmware. However, in July 2015 Ubiquiti released
a new version of firmware XM.v5.6.X. With this firmware a new U-Boot
version was released, U-Boot 1.1.4.2-s956 (Jun 10 2015 - 10:54:50). The
newer U-Boot version changes the memory size and starting address for
rootfs, cfg, and EEPROM. LOADING AN OPENWRT IMAGE ON A U-Boot
1.1.4.2-s956 WILL CAUSE THE DEVICE TO BE BRICKED!!!
If the device has XM.v5.6.X, an older version of XM firmware can be
loaded from the AirOS webgui (for example XM.v5.5.10) and U-Boot will be
overwritten with the older version. OpenWRT can then be loaded onto the
device successfully.
Take this warning seriously!
Every Ubiquiti airMAX device (all of the ones we use) with AirOS 5.6 or
AirOS 6 has to be **downgraded** to AirOS 5.5 **before** flashing with
LibreMesh/LEDE/OpenWrt.
You can find the old versions of AirOS 5.5 XM and XW here:
https://dl.ubnt.com/firmwares/XN-fw/v5.5.11/XM.v5.5.11.28002.150723.1344.bin
https://dl.ubnt.com/firmwares/XW-fw/v5.5.10/XW.v5.5.10-u2.28005.150723.1358…
If you accidentally flash LibreMesh/LEDE/OpenWrt on top of AirOS 5.6 or
6 you will have to disassemble the router (not trivial for some of the
routers!), connect to the serial port with an adapter and follow the
instructions here:
