Default [Q] Galaxy S4 goes into Factory Mode instead of Download

When I turn off my Samsung Galaxy S4 (GT-i9500) and push the volume down, home button and power button to go into Download Mode I get a purple text that says Factory Mode and shows this:
工厂模式(Gōng chǎng m sh)=factory model
完整测试(Wn zhěng c sh)=complete testing
单项测试(Dān xing c sh)=single testing
测试报告(C sh bo go)=test report
清除e MMC(Qīng ch e MMC)=Clear/Remove/reset e MMC
版本信息(Bǎn běn xn xī)=Version Information
重启手机(Chng qǐ shǒu jī)= restarting the phone

(I got the translations off of another website as I was browsing around for answers)

I really want to root my S4 and I can't root it unless I can access my download mode. Is there another way I can access the download mode on a unrooted S4 or if I could get rid of this Factory Mode menu that shows up?

Also, why is my S4 showing this instead of download mode?
