My N9 is essentially dead after I got a humidity problem on the outside. It switches on including the vibration, showing the logo, but then the bootloader reboots again. When using the flasher there are two abnormalities: flasher -i does not find a serial number and trying to flash the phone get's an error 7 in SU_GET_PARAMETER_REQ, "Unable to get SU_PARAM_BATTERY_LEVEL".

Obviously the battery logic is damaged. I ordered a brand new battery and put it into the phone, now I don't need the charger connected to boot up, so the battery's power is connected to the main board, but the error persists.

I cleaned the main board and everything else with isopropyl alcohol.

When I opened the phone the first time after the damage, I found white remainants around the battery area, the battery itself looking normal. The main board had now traces of liquid at all.

Is there hope for the device? Some sort of fuse I can replace? Some flasher-tricks to restore functionality? (I had inception installed but did not use it for anything.)




Full story leading to it: Waking up one morning the phone was lying on a wet surface, display down, the phone itself wet on the outside. I immediatly turned it off, wiped it and put it upright into the morning sun to dry. Half an hour later I noticed that the leds were on full power. It was not possible to switch off the device. I then put the phone into a heap of rice and waited for a day.
