Topic: Ubiquiti NS2, re-flash with OpenWrt and back again

The content of this topic has been archived on 20 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

I have a spare NS2 and I'd like to put OpenWrt on it.

I found openwrt-atheros-ubnt2-squashfs.bin out in the downloads area and I just wanted to ask if this .bin is directly flashable from the GUI.

If so, and I want to flash back to the Ubiquiti OS, is this possilbe via the OpenWrt GUI ?

Thanks

Found Some info in the wiki;
"The OpenWrt buildroot generates images that can be directly flashed to the NS2, usually with a name like openwrt-atheros-ubnt2-squashfs.bin."
Sounds easy.

But I don't understand ;
"In order to upgrade from OpenWrt to a newer version, both the kernel mtd and filesystem mtd must be reflashed. The kernel is likely lzma compressed. If either mtd block isn't big enough, reflashing can not be completed through OpenWrt, but must be done through the RedBoot bootloader. "

Is this just saying the GUI won't, but Tftping to the device and reflashing will ?

The rollback described uses Tftp to recover back to their Air OS.

Guess I'm just being paranoid. I hate bricks ;o)

The discussion might have continued from here.
