This is an unbrick method for us VM users finally you guys can go and screw up your phones intentionally and, messing with our bootloaders and recoveries will be a lot easier and what not now! Credit goes to Sammyz for providing the firmware, I'm nearly sharing Sammyz content. We need a tester that wants to try it out as we haven't found one yet.. Anyone have a bricked F3 they want to try and fix? Or one they just want to reflash back to stock for some reason? It is the official VM firmware, and the original thread can be found in the MetroPCS section of the Optimus F3 if you'd like to look. This .cab file does need to be converted to a .kdz and then flashed the same way you would on the LG Motion. (I'm sure an easy Google search can solve those problems for you.) I'm gonna ask if Sammyz can go ahead and convert it to a .kdz for us tho. Then I'll post a guide! My very first one lol I TAKE NO RESPONSIBILITY FOR ANY PROBLEMS THAT ARISE DURING THE PROCESS. I myself don't have a bricked F3 to try it. Maybe someday.
