Question More help with Panasonic GD90 cable

Hi again all!!

I have a few more questions on how to unlock a gd90...

Today I made the cable as it is presented on <a href="" target="_blank"></a>

The only problem is that the voltage (-12V) out of the com port, which should reach the 78L05 stops at the diodes (1N4148) because it's negative, it should be 12V not -12V.

As a result nothing is sent to the phone as there is no voltage in the circuit... how can I fix this??

Grateful for help!!
