Linksys rt3200: radio0 device is not active (mt7622)

Installing and Using OpenWrt Network and Wireless Configuration
#1

Hello,
I am struggling with lastest
openwrt-mediatek-mt7622-linksys_e8450-ubi-squashfs-sysupgrade
on a freshly installed belkin rt3200.
I can't enable radio0 ( on 2ghz freqs), radio1 is working fine.
I am on OpenWrt SNAPSHOT r18125-b764cb9e5b
I tried cleaning configuration and restarting from scratch but I always never manage to enable radio0
I am attaching relevant config and log
can anyone please point me to some hint?
Thanks
A.

Oh, that looks weird. Please check if the firmware files /lib/firmware/mediatek/mt7622_rom_patch.bin and /lib/firmware/mediatek/mt7622_n9.bin are in place (why ever they should be missing?).
Next step is to check for EEPROM data in hexdump -C /dev/mtd2 which should start with

00000000  22 76 .. ..

If both are present and you are using an official build, I'm afraid the hardware has a problem (which may even be something as odd as the power supply being too weak).

Hi,
thanks for your answer
everything looks in place:

please note that I tested the router before flashing and with the stock belkin firmware the 2ghz radio was working.

I will try moving the power supply thanks

happy holidays

even changing the socket always gives me
