So ive been having fun with my optimus m 2.2.2 flashing mods and rooting it and attemptimg to overclock but now I want to do something new, manual update. I believe the most recent os is 4.1.2 as of oct. 8 or 9th so wondering if its possible to manually update my optimus from 2.2.2 to a higher version, preferably 4.anything, will settle for 2.3.1. Step by step no matter how long the process, please.
