Ubiquiti Unifi AC MESH

Hi all,

I see a sysupgrade firmware have been release in the snapshot section for the Ubiquiti Unifi AC MESH. Have anyone done this and can you give me any info on the partitions/sysupgrade flash procedure? Just concerned that the old boot loader issue might cause me to brick the device. I've bricked some Pico's by not reverting to older Ubiquiti firmware to adapt to correct bootloader.

The only flash info I could find was on the AC lite and AC pro/LR here:

According to this post a LEDE image was succesfully flashed on to partition0

Will I be "safe" following the AC Lite method:
'scp openwrt-ar71xx-generic-ubnt-unifiaclede-ar71xx-generic-ubnt-unifiac-mesh-squashfs-sysupgrade.bin-squashfs-sysupgrade.bin ubnt@
mtd write /tmp/openwrt-ar71xx-generic-ubnt-unifiaclede-ar71xx-generic-ubnt-unifiac-mesh-squashfs-sysupgrade.bin-squashfs-sysupgrade.bin kernel0'

Some guidance would be much appreciated.

Hi, I flashed without problem an Unifi AC Mesh (UAP-AC-M).
I used the latest snapshot and I wrote kernel0 and kernel1 (openwrt wiki > UniFi AP AC Lite devices method).
Now I restored original firmware (you can use TFTP method, be sure to use a switch between AP e PC).


Thanks a lot for the input, I've managed to flash 6 of them this way and have created a mesh network. Will update on the speeds I'm getting, so far i've been getting reliable links at 1500mbps. Will post some real throughput tests here.

Hello @wernerwireless

I also have bunch of Ubiquity Unifi AC Mesh devices that I like to flash with LEDE or OpenWrt to combine the great hardware with the even greater power of LEDE / OpenWrt to build a batman-adv based mesh wifi.

Unfortunately the OpenWrt firmware version you mentioned is not available - or I can not find it.
I found a LEDE snapshot version exact for this device. Can I use this version in the same way that you described, with the addition of flashing to both kernels?


I followed this instruction
and I thinkI bricked two of the UAP-AC-M devices :fearful:


okay these devices where bricked. I reset using TFTP Recovery described there: https://help.ubnt.com/hc/en-us/articles/204910124-UniFi-TFTP-Recovery-for-Bricked-Access-Points

I was successful with using the SNAPSHOT for UAC-AP-Mesh but then batman-adv was not compatible due to kernel mismatch stuff.
Therefore I used the 17.02.1 version for UAC-AP-Lite and it works.
