AXP209 / Cubietruck killed with 12 V

Hi all,

I have applied 12 V to the DC input of my Cubietruck (bad thing). So now I want to repair / recover everything possible...

Both DC-in and battery input seem to be short-circuited, but I cannot find the exact position.  Power via USB-OTG works (successful boot).

The fuse directly after the input has almost zero resistance (which is good) and I have checked all visible power-related parts (doc here) with a microscope (nothing looks burned, as far as I can tell all diodes/resistors/... work as they should).

When checking the resistance of DC-in to ground it gives me 1,5 kOhm with a multimeter (don't have a second one here, but I guess its voltage is ~0.5 to 1V).

In the PMU docs it says the PMU can handle over-voltage up to 11 V ( ). Still I hope a short 12V-input hasn't instantly killed the PMU, as USB power works (iirc also linked to MPU).

Is there anything I can try to check / fix / replace apart from the PMU?

Thanks for answers.
