Reflash your device with PR 1.3 FIASCO and eMMC (Check for the latest one as you'll find 2 eMMC images. Te latest came around 1 month after PR1.2 i presume). However, after you do this, just check if the phone is doing ok, if it is restore your backup. If not reflash again. I have done 3 flashes of eMMC and the Fiasco Images until the phone became a piece of butter with smooooooooooooooooooooooothie transitions and perfection that dint exist in Nokia devices since like..... forever.
