I purchased samsung galaxy s3 off ebay supposed to have been brand new. However, I discovered yesterday at Verizon that my phone is rooted when we were trying to update it to the current software version. I contacted the company (pupup wireless) and asked if my phone was rooted they said yes. That they do it all their phones before sending them out due to people wanting them rooted. I was wondering whats the simplest/easiest way I can unroot this device so I can do the software updates OTA with verizon. I do not know anything about rooting or unrooting. Is there anything I can do to get this device unrooted or am i screwed? Thanks
