I own an LG Optimus L9 from T-Mobile. A few months ago, I rooted it and installed the Jarvis boot animation, complete with a Jarvis start up sound.
I started having issues with my phone, so I performed a factory reset. However, the boot animation is still the Jarvis one. I need to send the device in for a repair, and I need it back to the original boot animation (one where there was white and pink squares that did a wave animation, along with the T-Mobile jingle.)
Can someone help me step by step?
