RainMachine8 Gen2: Cannot set wifi to DE (enable channels 12 - 13)

I'm hoping someone can offer some advice on troubleshooting this. I'm trying to enable wifi channels 12 and 13 on my RainMachine8 Gen2, without success.

I've successfully logged in via SSH.
Set a new SSH password - confirmed this via logging out and back in with new password.
followed the step here without success: https://support.rainmachine.com/hc/en-us/articles/227848767-WIFI-Troubleshooting
tried the following without success:
uci set wireless.radio0.country=‘DE’
iw reg set DE
uci set wireless.radio0.country=DE
after setting any of the above i get (before and after reboot):
root@RainMachine:~# iw reg get
country US: DFS-FCC
(2402 - 2472 @ 40), (3, 27)
(5170 - 5250 @ 80), (3, 17)
(5250 - 5330 @ 80), (3, 24), DFS
(5490 - 5600 @ 80), (3, 24), DFS
(5650 - 5710 @ 40), (3, 24), DFS
(5735 - 5835 @ 80), (3, 30)
(57240 - 63720 @ 2160), (N/A, 40)
however I do get the following also, which shows wireless device as DE:
root@RainMachine:~# uci show wireless
wireless.radio0=wifi-device
wireless.radio0.type=mac80211
wireless.radio0.channel=11
wireless.radio0.hwmode=11ng
wireless.radio0.path=platform/ar933x_wmac
wireless.radio0.ht_capab=SHORT-GI-20 SHORT-GI-40 RX-STBC1 DSSS_CCK-40
wireless.radio0.htmode=HT20
wireless.radio0.country=DE
wireless.@wifi-iface[0]=wifi-iface
wireless.@wifi-iface[0].device=radio0
wireless.@wifi-iface[0].network=wlan0
wireless.@wifi-iface[0].ssid=XXX
wireless.@wifi-iface[0].mode=sta
wireless.@wifi-iface[0].encryption=psk2
wireless.@wifi-iface[0].key=XX

It seems i cannot set the county to DE (or any other country but US), as seen via iw reg get. It stays as US with channels 12-13 disabled as confirmed via:

root@RainMachine:~# iw list |grep MHz
* 2412 MHz [1] (27.0 dBm)
* 2417 MHz [2] (27.0 dBm)
* 2422 MHz [3] (27.0 dBm)
* 2427 MHz [4] (27.0 dBm)
* 2432 MHz [5] (27.0 dBm)
* 2437 MHz [6] (27.0 dBm)
* 2442 MHz [7] (27.0 dBm)
* 2447 MHz [8] (27.0 dBm)
* 2452 MHz [9] (27.0 dBm)
* 2457 MHz [10] (27.0 dBm)
* 2462 MHz [11] (27.0 dBm)
* 2467 MHz [12] (disabled)
* 2472 MHz [13] (disabled)
* 2484 MHz [14] (disabled)
total <= 1, #channels <= 1, STA/AP BI must match, radar detect widths: { 20 MHz (no HT), 20 MH z }
* short GI for 40 MHz

Going to https://192.168.0.88:8080/api/4/provision/wifi?format give this result. Perhaps the region cannot be set as the wifi is managed?

  "macAddress": "XXX", 
  "ssid": "XXX", 
  "netmaskAddress": "255.255.255.0", 
  "hasClientLink": true, 
  "mode": "managed", 
  "interface": "wlan0", 
  "lastWIFICheckTimestamp": 1530842656, 
  "ipAddress": "192.168.0.88"

Any advice or assistance would be helpful. Channels 1-11 in my area are busy!

Does your setting stick without rebooting ? I tried on my Mini-8 and it changes.

Thanks. Before reboot it is showing DE, however channels 12-14 are not active. Unit will not connect to these channels.

With country set to DE, could you check to see if your channels 12-14 are active?

Looks like the channels >11 are restricted in the wifi firmware because of some export regulations. We'll check if we can workaround this in the current firmware version.

The enabling procedure is pretty complicated and involves editing directly on flash memory at certain locations. Not something users should do, let me see if we can come up with something safe to do without bricking the device.
