Thanks mate!
I was too late, the file is already gone from anonfiles.com and I too cannot make baidu work for me, they are not letting anyone outside of china make accounts 
any chance you can put it up again?
Would it be possible to link to a binary again please?
I have tried downloading and building from the github at tonynii/openwrt but i was getting build errors that I couldn't work out. So then I downloaded the main sources from the openwrt/openwrt github, and manually made the changes (that I could find) from the tonynii repository. I think I may have missed something though - I have successfully uploaded the firmware, but the 5GHz network doesn't seem to be detected. I am getting the following errors in dmesg, and have no idea how to fix it.
dmesg | grep wifi
