Tried installing a new rom, just went into a boot loop. Now I can't get my PC to recognize my device to install a different rom. I can go into fast boot but when I try to go into recovery all I get is Mr. Android with the big red above his chest. Where do I go from here, I'm not an expert at this but I can figure things out when explained clearly. If I can get this figured out my goal is to be full stock rooted. Thank you in advance, I really need my N7 for work.
