VVDI PROG

[recodes]

The xdg128 I read is from BMW F11 JBBFE3 or JBE junction box module. Main gateway for the car. Should I add photos? Can anybody help with how to unlock it now? Can the program be updated to not lock the chip when you erase it?

Read MC9s12xdg128 2M42E tonight. Very smooth easy read and verify flash and eeprom. Security bit is at 1ff0f and is 0xfe unsecured.
I erased the eeprom then erased the flash thinking of course the software would not be written so as to secure the chip and will write security byte 0xfe....
No chip is now locked!!! Why do this?
How do I recover the chip now please?
Thank you

Use the option 2-MCU,MOTOROLA-MC9S12,MC9S12XDG128_SUCURED to write directly(and connect the chip by this options's wire connection)

Did you read it successfully? And why you want to erase it???

Yes I read it successfully. I read it because AVDI killed it writing VIN. I replaced the unit so wanted to try reading the old one and see if I could recover it. To be honest I was curious to see if the erase command would set the security bit because this module is not required so trying the erase command on this one I would know not to use it on a module I do need if this happened.

This is how I read it and erased it and how it will not read anymore.

Edit:
Do you mean, although I can no longer read it I may be able to write the saved dumps back using this method, the method I read it with initially?
Thank you for your replies.

You don't need to erase anything. Read it. Make changes. Write it back. Only point of unlocking it would be if you want to read and write it with some other tool that cannot bypass security without erasing it.

Hello in future is any chance to add Micronas family CDC32XX ??

[dsgwizz]

would this tool (VVDI2) be able to read and remove the immo4 on the newer med9.1 with rsa2 checksums from the 2012 to 2013 model GOLF R. 1k8907115D , with Vdo clusters.

good thread btw.

The changes I wanted to make was to erase it. AVDI killed it but I can not find any dumps anywhere to revive so I wanted to erase first and go from there. As I say I could have manually changed all bytes to FF leaving 1ff0f 0xfe but I was interested to see if the erase command would do this or not. I found out it does not.
So now that vvdi prog does not read it; How should I read and write the contents of this chip? I have tried to remove but even when hot enough to lift legs it seems the chip is stuck to the board somehow!

Thank you

I did the Tricore 1766 on the ECU SIM2K-341 today and it was quite successful, I corrected 4 resistors of 470 ohms

yes,even can't read,you can try to write it directly.how is the result?

I have just tried. No read, no write. The chip will return correct ID c102 but no read or write.
Maybe this could be looked at for future versions? I cant see anybody wanting to erase and lock the chip like this, at least not without warning maybe?

you must have chosen the wrong option,please check PM

2010 VW golf ECU MED17.1 tc1796 failed to read. part number 1k0907115AQ
can somebody confirm that tool can supports that module or its a mistake on my end
