Hi, I really hope someone can help me cause I have no idea where to start with this... I just bought an LG Intuition smartphone from Craigslist, the guy was a student like me and nothing seemed unusual about it. I get home and realize he left his sim card in the phone, hmmm.. but anyway my problems start with the phone having a different size sim card slot than the sim card i current have with Verizon. So i went to Verizon and first they were like yea sure we can swap you to the smaller size card no problem, so I was like awesome. Then she starts running into all these problems and says that the ID (EMEI) number is not found in their database. I didn't know what shes was talking about but she was basically saying the phone was probably rooted to use on another carrier and that changed the ID number... FRUSTRATED I went home and called Verizon technical support, their answer was pretty much the same, the tech said I would have to "flash" the phone back to Verizon firmware settings to be able to register a sim card with the phone. I am not sure what to do, I downloaded an app called root checker, it says this device does not have proper root access. I guess that means its not currently rooted? The phone currently reads IMEI number: 990002574975296 Id be so grateful if someone knew how to solve this, I am so stuck THANKS!
