This is a joint blog post written together with Matija Šuklje with the goal to disband some popular FUD that you lose your warranty if you flash or root your device
Rooting your phone
Does rooting your device (e.g. an Android phone) and replacing its operating system with something else void your statutory warranty, if you are a consumer?
In short: No. Just the fact that you modified or changed the software of your device, is not a sufficient reason to void your statutory warranty. As long as you have bought the device as a consumer in the European Union.
