R4AC International Version Firmware Dump

Hi everyone,

I was using OpenWRT and it was quite good but i couldn't see any 5 GHz channel on Wireless so I thinking that I might flash wrong version. I tried flashing Chinese version because I couldn't find any International version so I am stuck here, I can't restore to 3.0.5 anymore. If anyone dumped firmware with some SPI like ch341a before, can someone put it here ? Thanks.
