How on earth are we supose to supply you with software for a cloned S4 when it doesn't even accept official Samsung firmware?
I have gone through some chinese forums for you and the only firmwares I can find are the ones for the iPhone 4S clones.
Besides listing what CPU it runs on, what is the actual firmware called?
White Samsung Galaxy S4 LTE i9505 + white S view Cover for everyday, Protective Cover+ for hiking, camping etc...
Rom: Stock non-rooted 4.4.2
SD card: 16 GB Class 10
Tablet: White iPad Mini + Green Smart cover
Firmware: iOS 7.1
Samsung Galaxy Tab 2 7.0 (Family tab)
ROM Stock 4.1.2
