Been thinking about making the switch for the .893 update even though I really have been loving liberty over stock. Seems to run a lot smoother deblurred and the battery life is much improved. Any opinions on people who have made the switch from liberty to purity? Also, can someone please leave me a simple step by step to flash from roms safely? Can i just flash to Purity from Liberty or do i need to go back to completely stock first? Would I need to re-calibrate battery? Thanks for any feedback.
