I'm new to this also did alot of reading before I post this thread.
I've a a Samsung GT-I9500 Tried connecting it with Odin or Sam kies they are not able to connect to device. Also noticed that my pc in device manager at portable devices it recognize it and give that it's a GT-I9500.
I wanted to root the device but was not able with Odin (reason that it does not connect) so I tried motochopper which worked for me and also detected the phone. Forgot to say I've installed USB driver for samsung galaxy s4 before trying to connect with odin also with Sam kies.\
After rooted with motochopper was able to dwnl titanium back up and root but now I'm stock at the part of flashing.
Now I want to flash my rom to get new firmware but I'm not able cause the Odin does not detect device. Also when I turn off phone to boot in download mode by pressing vol dwon , home button and power button. It tells me factory mode then a bunch of (guess) chinese menu option.
Because of this went to search if my device was original or fake and still not sure tried many things and apps which tells me that it original.
My whole question is what should I look at to let Odin connect with device.
