How to revert Galaxy S5 to Stock ROM?

[BBGary]

So i got my Beautiful Galaxy S5 from Telus and as usual with all the phones i have, i unlocked it. So far so good. Next thing was to root it and to start with custom ROMs. So I used the method described in galaxys5root.com with 100% of success. I tried couple of ROMs and i did not like it. My problems started when i decided to go back to Stock ROM from Telus. I flashed the stock rom that i found on the same site i used for rooting the phone and got a Bell phone. Now whatever i do, i am ending with Bell stock S5 and i want my Telus stock. Trying emergency recovery didn't help. I could take the phone back because i have it only for a couple of days, but i put a good screen protector (40$) and i do not want to pay for unlocking the phone again as well.
Please help me in solving my problem. Any feedback is highly appriciated:'-.

That ROM is no longer contained in storage unless you created a backup prior to flashing the first ROM. In order to get back to Stock you'll need to flash a factory image. If you're unable to find the file online, typically this is done via KIES.
