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 mó shì）=factory model
完整测试（Wán zhěng cè shì）=complete testing
单项测试(Dān xiàng cè shì)=single testing
测试报告（Cè shì bào gào）=test report
清除e MMC（Qīng chú e MMC）=Clear/Remove/reset e MMC
版本信息（Bǎn běn xìn xī）=Version Information
重启手机（Chóng 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?
