Upgrade Android 4.2 - GT9195 - without USB



Hey,

I've rooted my S4 a long time ago. Now I wanna upgrade to Android 4.4. I downloaded the file from sammobile.
The issue. My usb port in not working. I was searching to a alternative instead of odin. But odin mobile is not compatible with my device.

Any idea how to use a new firmware or unroot my device with just using wlan?

Thank you very much:o

PS: I tried to read about flashfire. But there comes a warning message and its too complicated to find a solution on my own: Samsung write protection. I am a noob. So I don't want to try it with this method.
