I want to update my firmware to Lollipop 5.1.1, I have Lollipop 5.0.2 and my carrier is WIND MOBILE (Canada).
I´ve used the Indian stock rom from sammmobile and I´ve tried with other pc, other port usb, other cable and always is the same problem. What can I do? Please help me. Thanks.

Is the phone still locked?? Is the same csc that you're trying to flash??

No, I´m using Stock rom from India and my stock rom is from Canada, so, is not the same CSC. And are you talking about that my phone is locked to others companies? If is that, the reply is YES, still locked.

if you are using a ROM form a different country, it could be built for a different Variant.
Try a Canadian Stock 5.1.1 ROM.
Word of warning, you cannot Downgrade from 5.1.1 to 5.0.2

Yeah, the problem is: We haven´t Lollipop 5.1.1 in Canada yet.

This might sound crazy but I had the same problem and I had a defective new Samsung USB cable!
I spent hours trying to flash stock firmware!
Only when I used another cable Odin 3.10.6 passed first time!

Solution!
Try to wipe everything on your phone via CUSTOM RECOVERY, DONT WIPE YOUR SDCARD!!! (do not touch the odin settings unless you exactly know what they do!)
Try TWRP:
TWRP: twrp.me/Devices/
This will most likely work because then it will clean flash/install your rom.

If you have the phone locked, i think that you can't flash anything unless you unlock the bl. Try to flash the stock rom with a oldest version of ODIN (ex 3.07/3.00 or oldest...)
