Well i accidentally changed polarity of power supply on one R800i.
And now phone is on short state between battery connectors.

I am looking for components placement schematic.
Here i will upload schematic for r800i and will ask you to suggest me which component is defective?

All suggestions are welcome.
Need to remove that short and revive the phone.

thank you
