RT-AC56U broken wifi (possible cfe issue)

[Zaspath]

Hi,

I was having issues with internet dropping out, I restarted the router as normal, but since found my 2.4ghz and 5ghz config in mess, it's showing 5ghz as channel 0 and 2.4ghz as channel 46-48 (Which is obviously 5ghz, but something is really messed up). I've tried re-flashing merlin wrt 380.57 multiple times, no change, I've tried clearing NVRAM by holding the WPS button when you power on the device, no change.

The wireless is just a mess from the start like it's got corrupt data. I seem to have lost 2.4ghz completely , the settings in the 2.4ghz are reflecting 5ghz settings. Disabling/enabling radio doesn't help.

I even reflashed the CFE using mtd-write from the dumps page... no good.

Is this unit damaged now? Occasionally there is a prompt asking for the Country Code in broken English, can't remember the exact words. When I inspect the page and look at Advanced_Wireless_Content.asp

wl_channel_list_2g = ["36", "40", "44", "48"];
wl_channel_list_5g = ["0"];
var cur_control_channel = [["48", "0"]][0];
var wl_unit = 0;
var country = '';

Is my router useless now? Has it lost the country data? Any help greatly appreciated. Oh and when I go to Wireless log it breaks the page because something is corrupt in the config I assume.

I'll supply whatever I can on request, please help I'm going mad.

Thanks.

Have you tried holding in the reset button on the back until the power light blinks?

Thanks for the reply, I did yes, no change, I think I'll need to RMA it, only had it 3 months.
