Ok, so i was planning on flashing to neat rom, but in anticipation of this i did a factory reset of my phone. I am running the latest siyah kernel. Now the samsung galaxy logo appears, then the phone just flashes grey, i can get into download mode so i'm not completely lost, but i don't have a clue what to do next. I tried all the hard and soft reset things to no avail. Can somebody please help me, i'm pretty desperate.
