menabassily:JimmyH:ibuksh: just keep in mind, using Odin will void your warranty..
The Networks may say that, loudly and frequently. However, if the phone failed because of something unrelated to the firmware update you did (say, a faulty screen?), then I doubt trying to exclude it from warranty coverage because of an unofficial firmware update would withstand a challenge under the Consumer Guarantees Act if you took it to the Disputes Tribunal. Likely, even mentioning the CGA would make them cave before this point.
So I'm not sure if I got this right, so you're saying that even a rooted phone "should" be warranted/serviced for not firmware related issue (screen for example)??
I'm interested in more details :)
Same principal as an insurance company trying to decline a claim because a vehicle had no W.O.F. They still have to prove that a fault with the vehicle (which would have been detected during a W.O.F check) contributed to the accident.
In the case of a faulty phone Samsung/retailer would still have to prove flashing the firmware contributed to the fault before they refuse to honour the warranty.
