Asus TUF Gaming AX6000 support

Hi Everyone, I have lost wifi connection on TUF-AX6000 after trying to do attended sysupgrade. It got bricked, I managed to bring back with ASUS firmware restoration tool, but since then wifi only works with ASUS stock firmware, and not OpenWrt.
In kernel log I see mt798x-wmac 18000000.wifi: eeprom load fail, use default bin

Seems to be similar to Asus TUF AX4200 support - #145 by Funnyland where calibration data on flash got lost. Maybe someone could share a backup so I could try to reflash it?
BogdanZag had also similar issue in December with TUF-AX6000.
Regenerating wireless file with wifi config command gives wireless config with both radio0 and radio1 being 5ghz, but even after enabling neither ssid is visible.

From wireless config

config wifi-device 'radio0'
        option type 'mac80211'
        option path 'platform/soc/18000000.wifi'
        option channel '36'
        option band '5g'
        option htmode 'HE80'
....
config wifi-device 'radio1'
        option type 'mac80211'
        option path 'platform/soc/18000000.wifi+1'
        option channel '36'
        option band '5g'
        option htmode 'HE80'

...

Any hint would be appreciated, thanks in advance!
