Need help to fix or bypass "secure booting error! Error code: 1003. Modified" on a LG Stylo. Not sure what carrier, it was given to me with sprint logo on the SIM card... I called LG about the issue and gave the the IMEI number and the said it was a Virgin Mobile device. It should be rooted. I downloaded and installed the king root. At first it said the was no root for the phone at the time, then gave me an option to do it anyway at my own risk, so I did, then it said it was successful so I proceeded on. Left phone on all night, still had power, a lot of power. Then I wanted to try a different SIM so I put it in and proceeded to restart the phone then that's when I incountered the error msg apond reboot.... Please help.
