Hi All,

I received last week my new Bullet M, and I confirm it is still
possible to downgrade to 5.5.10
It was shipped with 5.6.11, but I wanted to confirm that I can
downgrade from latest AirOS version, so what I did:

1) Upgrade to 6.1.6
XM.v6.1.6.32290.180307.1650.bin (md5sum 96a876222ede2cac4b2e895c14160c31)
This version only accept signed image via the WebUI

2) Downgrade to 6.0.6-beta
XM.v6.0.6-beta.30875.170526.0038.bin (md5sum 6baf82898fd70e9d394fb3b5a17d6fc3)
This version is signed but accept non signed image via the WebUI

3) Downgrade to 5.6.15
XM.v5.6.15.30572.170328.1107.bin (md5sum dbe0fe1c5404c19f0adf328ca8d01a7a)
6.0.6-beta refuses to go back to 5.5.10 directly, so I went to 5.6.15
(unsigned version)

4) Downgrade to 5.5.10
XM.v5.5.10.24241.141001.1649.bin (md5sum 288b6dd2cbf35a85582f942ae5489873)

5) Upgrade to LEDE 17.01 \o/
using the WebUI and the factory image


Adrian Schmutzler sent me another downgrade path that they use with
OpenWRT-based Freifunk Franken Firmware
XM.v6.0.6-beta.30875.170526.0038.bin
XM.v6.0.4.30805.170505.1525.bin
XM.v5.5.11.28002.150723.1344.bin


Also I want to point to another email thread "ar71xx: Ubiquiti Airmax
M: add relocate-kernel to invalidate cache"
http://lists.infradead.org/pipermail/lede-dev/2018-April/011980.html
According to this thread OpenWRT master should be compatible with all AirOS 5.X

Cheers
Etienne
