Hello, I'm using Samsung s4 (GT-I9505 carrier free) device and I tried to root my device with ODIN. But the process got failed and now my device is briked. When I switch on my device I get an error "Firmware upgrade encountered an issue. Please select recovery mode in kies & try again". I tried recovering my device using kies but kies was unable to initialize my device model. Please help me to unbrick my device. Thanks in advance.
