Is all you need to guarantee the success of a warranty to unroot the phone after rooting it (and flashing a ROM)? Some friends tell me that running an app called Triangle away is needed and also locking bootloader is also required. Is this true, and if so, would there be anything else I'd need to do if I rooted my phone and wanted to claim it back? Sorry but If you can't root and claim back your phone, it seems like an extremely risky move to make..
Thanks
