Indeed, I have seen that one. Well, despite the "risk" that you play with a flasher, issue is I need a firmware, even that I would not use it in the end. This brought me to searching the correct firmware for this excersize, and I got a bit stuck. I have currently a DFL61_HARMATTAN_40.2012.21-3_PR_001 (white, 64GBs, NEurope). If somebody can give me a link for this FW so I can use its bin, would be appreciated.

On the other hand I wonder what N9 is really trying to do. I do successive plugins to the charger and the white led stays continuously ON for ~2:30 min, after that it makes that specific sound and blinks few times, then goes OFF. I wonder if during this process any power goes into the battery and if successive attempts like this have any chance in incrementally charge the phone to the point where I can boot it? Any view?
