How to root Samsung Galaxy S4 without PC? topic

My device's USB port is not responding. Can't charge the phone or connect to PC. And all backup/restore apps for app data backup requires the device to be rooted. So I'm trying to root the device, get a data backup of some of my apps and move the data to a new device and restore it there.

Here are some details of my device:

Model: GT-I9505
Android version: 4.4.2
Baseband: I9505ZHUFNL1
Kernel: 3.4.0-3501301

Can anyone give me some help on either:

How to root the device without a PC? or How to backup app data and restore it on another device?

I've tried these apps for rooting already: towelroot, KingRoot, Poot, and iRoot. All failed...

Thanks,

K
