Hmmm, Hi I bought an LG Optimus One P500 1 month ago. I wanted to put some music, I checked the ''Mass Storage Only'' on the '' SD Card & Phone Storage Settings'' and then, ploged it on my PC. And it works fine, my PC detected my cellphone. Today I wanted to put some songs of the LFMAO album I bought, so I did the same things that the last time. Surprise, nothing happened . I search like a crazy guy EVERYWHERE, and tryed EVERYTHING. Nothing worked. I installed the LG USB Driver but it doesn't work. I don't know wath it's wrong or if there is a big probleme on my cellphone or my computer but i need help, please. Is there more people who has the same problem? Is there people who know how to repair this? Do I need to go see the store (Futur Shop (Koodo)) where I bought it? Or send it to the compagny so they can repair my phone?
