I flashed 1.41 i poked around to feel it out. Decided to go back to 1.3 but got an error in cwmr at the beginning of the flash process. That was the first time i had ever recieved an error in recovery (esteem and optimus m). I had done the wipe process already so i just restarted cwmr and flashed sucessfully. Not sure if this info is of value to you but i see how dedicated you are to your project so i thought i would bring up any odd problem i come across.
