R-JTAG Reattaching broken off points on RJTAG board

Please help with resoldering points back on the RJTAG board.

Description of problem:
I pretinned the connecting points on the RJTAG board and attached the corresponding wires. Then when I was attaching the other end of the wires to the J2B1 QSB the blue and green wires broke off the D & E connection points on the RJTAG board exposing a brown underside (see pictures).

However now when I apply flux and try to pretin the points on the RJTAG board I can not get the solder to connect to the brown points. Is there way to do this? How do I reattach the wires to the points again? I am stuck

You shouldnt even be modding to be honest; send it to a pro..

You can't get solder to stick to the "brown points" because there is nothing for the solder to adhere to (you have lifted the solder pads after all).

You will need to use some thin wire (kynar should be fine) and solder to the correct IC pins or do as oO Elite Oo suggested and send your console to a pro.

Thank you for the suggestions. I am going to attempt to trace the pads to their corresponding IC pins and solder a thin connecting wire. I figure I have a go at it before having to buy another RJTAG board.

I traced the other pad points on the RJTAG board for future reference (1 being closest to C9):

D = ?
G = 13 pin
B = 14 pin
E = ?
F = 17 pin

I'm not able to trace points D & F with my continuity tester because of the state of the pads.

BL4K3Y, from this previous post you mentioned that pad D is the 8th or 9th pin. Do you happen to know the exact pin for D and also E from your previous experience soldering directly to the IC pin?

Or if anyone else has the tracing of the pads I would greatly appreciate it.

U said u have a multimeter, just do it, and find the exact pin. I mean even if someone was to tell me which one it was I would still make sure it's the right one.

The solder pads aren't magic - they are joined to other parts of the board using traces.

Use a fiberglass pen to expose the trace and track it yourself.

It would have taken you less time than already spent asking.

Like I mentioned, "I'm not able to trace points D & F with my continuity tester because of the state of the pads" and that is why I am asking for anyone with a working RJTAG board to trace the two pads for me.

Martin, I will try what you suggest.

So read my post again. the pads don't just float there. Expose the traces going to the pads.

Can't do it? You shouldn't be trying to fix it.

Thank you. Exposing the traces worked.

D = 8 pin
E = 16 pin
