Downoad Infinity-Box_cables_pinouts.rar and look at the 'Nec-N343i_Nec-E121.txt'. There are two testpoint pictures too.
btw, you can find there all pinouts , and the arhive is reguary updated ith new supported models.

There is a difference in "i don't see nothing about Nec E121 pinouts" and "some dificult to made a cable".
You need to find Ground pin in cable and connect to phone Gnd.
the try to apply Rx and Tx. If no connection: change Rx <-> Tx.
I think, your problem was, that you have forgot, that box's RX is the phones TX, and so on.

You don't especially need connector, just put RX, TX and GRD to indicated places.

Done!
Thanks for your help!
You are wellocome. :)
In addition: Those phones can be unlocked by two connecting methode:
With wires directly to pcb, as you have done it, if you don't have coonector,
or more easily with conector.
Some samsung Hands-free models uses this type of connectors, I think, so in the future you can make one if more Necs will be brought to you to operate them.
Good luck
