The connector has a security bar (blue in the photo). If this is not opened while inserting the pin, then the pin can not be inserted. Open the security bar with a small screwdriver or something alike at the red marked places. Then insert the pin, then. Push the security bar to close it, before connecting the connector back to the cmu.

Yes, I did it.
Thank you very much for the help and guidance.

Thanks for the feedback.

Reminder: The serial adapter should not stay connected permanently to the CMU. Only connect it, when in use. Otherwise it will drain your battery, as it receives data from the cmu even when the car is locked and it is not connected to a laptop.

How about the pin leave them connect but Serial adapter disconnect. 😅

I have some difficulties to remove the pins from the CMU connector;

Just curious that can downgrade software version to V56 so that there is no need to perform serial connection to get the tweak.

You have to unpin the pins in the connector if you want to remove them. Use e.g. a hair needle of your girl. Or use brute force - worked also some times for me, but the risk is, that the pin might stick in the connector and you remove the cable only.

No way to downgrade from 59.00.502 or higher to a lower version than 59.00.502. So no way to downgrade to FW 56.

Thank you 🙏

It happened to me, the wire was pulled out, pin still left inside in the connector. 😅

Example tools: Small screwdriver and a broken hair needle of my wife - these are the tools I use for the unpin process to unpin terminals from the front of the connector. Do not forget to open the security bar of the connector for pushing in a pin and pulling out a pin of a connector housing. For pushing the connector back to the CMU the security bar has to be pushed down, otherwise the connector will not go back in to the CMU.

If you have any intention of using the AIO software to apply tweaks to your system, DON'T upgrade to .502. USB connectivity has been removed, so if you have tweaks and upgrade, you're stuck with them. If you upgrade before applying tweaks, you are effectively shut out of the system and AIO won't work. Stay tuned for further developments.

UPDATE------
See the how to for the work-around starting here on this page -


I have tried connecting using serial cable but the usb does not recognize these tx and rx ports for some reason. I have tried different usb to ttl but none of them works. The rx and tx only lights up when they touch the body which is not useful at all. please help.

To me it looks like as if your pins/terminals (metal) are not deep enough in the connector. If you use the recommended/original pins/terminals, the metal can not be seen. Compare to the other cables in that connector - there you can not see the pins/terminals (metal). Have you opened the security bar like I showed in the post before yours, when inserting the pins/terminals? And do not forget to close the security bar afterwards, as without closing it, the connector can not be inserted in the CMU again.

i used my fingers to push it as much as possible, the tx and rx lights on my usb connector never lights up. i removed the metal pins and inserted wires directly and they still are not lighting up. Also, what do you mean by security bar? Do you mean the plastic clamp that's holding the connector? i never took it out from the port.

the pins come out whenever i insert them, how do you insert them so that they don't come out so easily? did you use the hairpin to insert the terminals?

@ad33b
You need to Strip more of the white and green wire about 2-3'inches (do not need pins/needle..etc). Disconnect the cable to the cmu unit. Thread the white wire all the way through as much as you can and pull/fold it up and over the connector. Do the same for the green wire but fold the wire downwards. Now making sure both wires are not touching each other and not coming out of the hole, at the same time slowly push the connector back to the cmu unit until it clicked or fully attached. Make sure to connect your black (ground) wire. I have used this method tonnes of times and it never failed. Everything should work. Report back your results.

@ad33b : No wonder, your pins are not inserted correctly. Remove the connector from the CMU. Then see e.g. this video starting at 1:18 min. for the correct opening of the "security bar"/gate of the connector:
Once open, insert the pins. Once they are inserted, close/push down the "security bar"/gate and connect the connector back to the CMU.

At the moment your pins are not deep enough in the connector and they have no electrical connection. The "security bar"/gate prevents the pushing deep enough so far.
