Hi!

Yes your PCB is bad under the cobba.

B.R.

I know it ;) , but which pin?

Check cobbaif lines!

me and my friend also find many cobba IC with ID 000000,, even new cobba made in china ,,, and nothing recalculate checksum ,,phone work ok even with ID 000000

not in my case .....

Check COBBAIF lines:
COBBA -> MAD2
A7 ----------- A7 (J316)
B7 ----------- A6 (J315)
D8 ----------- C6 (J317)

If not short circuit, link cobba to Mad. (If possible)
:) ...many skill ;)
