Just recently flashed cyanogenmod onto my Sony a few days ago. Wasn't for me so i decided to try and flash Doomlord's advanced stock kernel back onto my phone but cyanogenmod wouldn't come off. I decided to wipe all data from system, SD card, the lot and see if that would work by using cwm recovery but all that is happening now is the phone won't make it past the Sony logo, and occasionally just turns grey after that! I have tried wiping cache and wipe factory settings but no luck, also tried flashing a different ROM but still no luck, if someone could help me make progress then that would be great thanks, I still have hope left for my trusty Sony!
