You shouldn't use RJ45, there is RJ50 on JTAG picture (JATG connector in old Medusa Box - RJ50).

The problem is that i dont have the tool to do the rj50
What i think was i cut a rj45 cable and i have 8 wires ( on the picture we need to conect nine but "reset" is not obligatory) can i conect the other 8 with the correct order?

No, You can't usr RJ45 connector.

If You have Medusa Pro Box, You can repair this device via JTAG also, no need RJ50 connector, just use 20-pin adapter. To look at Medusa Pro Box JTAG pinout picture (20 pin), run Octoplus JTAG Pro Software, select "JTAG" option and press "Box Pinout (JTAG)" button:




To look at Octoplus Box JTAG cable's pinout picture (10 pin), run Octoplus JTAG Software and go to "Support & Options" tab:




Medusa Pro 20-pin adapter:



GND contacts are from the opposite side of adapter.


Also note, that repairing of this device is supported via eMMC (ISP). You can download SFR for repairing of this device via eMMC from the Support Area.

Press "Pinout" button to look and eMMC pinout picture and then use mouse wheel to increase picture size to look at pinout in details. You must clean the lacquer coating on PCB to solder the CLK wire.
