Background

Apparently there are two traces that have been interrupted which would allow serial port access.

These traces have been interrupted UNDER a SMD capacitor at position C54. Junker (see Yamasita's article/reference) discovered the way first[1]

Laitr Keiows and johnbock duplicated his efforts[2]

Method

C54

We need to fix these wires which go under C54:

Method 1: reconstruct the traces (on the backside)

This method requires absolutely no soldering.

Lay a layer of a scotch tape between holes, just not to cover them.

Use a strand of high flexible low oxygen copper wire.

  1. thread it thought both holes,
  2. fix it with a scotch tape on the back side and then
  3. cut remainders on the front side, leaving about 2 mm.
  4. repeat with the second thread.

Method 2: Bridge the traces (on the frontside)
