So today ive been trying to sbf back to 4.5.605 on my DX and though i followed video info correctly, i got an error. Err. A5,70,70,00,1F. I don't know what to do! I tried to sbf back to the 4.5.621 but nothing is happening. Now im stuck on the "SW Update In Progress..." I tried to use RSD Lite and its not working. Can anyone please help?? Im scared and have no idea what to do..
