Hi guys!

After my N9 died of full battery discharge, and refused to charge from the charger or PC, I tried the trick with flasher charging (up to 10%).
The first time I tried it it disconnected in the middle of sending the ape-algo image. I had no idea what it was and though I bricked the phone, as it wasn't recognized by the flasher afterwards. However, after I left it for some time (3-4 minutes) connected, it showed up.

I tried again and got that same Unable to get SU_PARAM_BATTERY_LEVEL message.

Disassembling the phone and disconnecting the battery for a couple of minutes worked, and with the message gone, the charge-via-flasher trick worked too!

Now, my question: Is there a way to force power off the N9 on 10% of the remaining charge, not 0%?
