Convert $5 USB-to-Ethernet adapter into D-Link DUB-E100 for MIB2 hacking

[mr-fix]

Requirements​

1. ASIX AX88772 USB to Ethernet dongle ($4.88 + S&H on AliExpress)
2. Linux (for example running on Raspberry Pi)

Procedure​

1. Turn on your Linux machine, connect ASIX dongle to USB port.
2. Install ethtool
   

   sudo apt-get update && sudo apt-get install ethtool

3. Check connected USB devices and look for ASIX Electronics Corp. AX88772B
   

   lsusb

4. Check if it's visible as network interface and what's the interface name. In next steps I'm using eth1 to point to the device.
   

   ifconfig

5. Check if EEPROM can be accessed
   

   sudo ethtool -i eth1

6. Read EEPROM
   

   sudo ethtool -e eth1

7. Confirm that offsets 0x0040 and 0x0080 contain "95 0b 2b 77".
   Notice the similarity between string "95 0b 2b 77" and "ID 0b95:772b" from earlier step.
   This is VID and PID of this device which we are going to change in next step.
8. Overwrite VID and PID with ones from D-Link DUB-E100 (0x2001, 0x1a02)
   

   sudo ethtool -E eth1 magic 0xdeadbeef offset 0x0088 value 0x01
   sudo ethtool -E eth1 magic 0xdeadbeef offset 0x0089 value 0x20
   sudo ethtool -E eth1 magic 0xdeadbeef offset 0x008A value 0x02
   sudo ethtool -E eth1 magic 0xdeadbeef offset 0x008B value 0x1a
   sudo ethtool -E eth1 magic 0xdeadbeef offset 0x0048 value 0x01
   sudo ethtool -E eth1 magic 0xdeadbeef offset 0x0049 value 0x20
   sudo ethtool -E eth1 magic 0xdeadbeef offset 0x004A value 0x02
   sudo ethtool -E eth1 magic 0xdeadbeef offset 0x004B value 0x1a

9. Read EEPROM agagin and confirm changes were made at offsets 0x0040 and 0x0080
   

   sudo ethtool -e eth1

10. Reconnect device and check if it identifies as D-Link DUB-E100
    

    lsusb

11. Done. Now you can connect it to the USB port in your car and it will be recognized by MIB as a network interface.

What does this allow you to do?

 

[mr-fix]

Access file system in Harman and Delphi units. This opens your way for MIB2 to MIB2.5 conversions, region conversions, patch for CarPlay/PerformanceMonitor/VoiceControl activation, CP removal, custom skins and sound.

Accéder au système de fichiers dans les unités Harman et Delphi. Cela ouvre la voie aux conversions MIB2 vers MIB2.5, aux conversions de région, au correctif pour l'activation de CarPlay/PerformanceMonitor/VoiceControl, à la suppression de CP, aux skins et au son personnalisés.

Bonjour, j'ai carat golf 7 avec le logiciel MIB2 version 0245 / 3Q0035877A MST2_RoA_VW_ZR_P0245T Mon problème est qu'il n'y a que deux langues en affichage américain et coréen Existe-t-il une solution pour ajouter la langue française ? et il n'y a pas de GPS installé sauf si vous vous connectez à téléphone une solution SVP et merci

Great tutorial!

Update: this gives better results if used in step 8.

#alternatively you can use PID 0x1a02
sudo ethtool -E eth1 magic 0xdeadbeef offset 0x0088 value 0x01
sudo ethtool -E eth1 magic 0xdeadbeef offset 0x0089 value 0x20
sudo ethtool -E eth1 magic 0xdeadbeef offset 0x008A value 0x02
sudo ethtool -E eth1 magic 0xdeadbeef offset 0x008B value 0x1a
sudo ethtool -E eth1 magic 0xdeadbeef offset 0x0048 value 0x01
sudo ethtool -E eth1 magic 0xdeadbeef offset 0x0049 value 0x20
sudo ethtool -E eth1 magic 0xdeadbeef offset 0x004A value 0x02
sudo ethtool -E eth1 magic 0xdeadbeef offset 0x004B value 0x1a

MIB2 to MIB2.5 conversions

This is very intriguing, could you give some more details? Is there anything new you get by upgrading? Does it let you to upgrade from a 8 inch screen to a 9.2 inch? I heard you can’t use a 9” inch screen with the MIB2 or something.

It can be done, but you need to now very well what you are doing.

Exactly as @JettiGLI said. It's tricky but it's possible to go MIB2 to MIB2.5, convert between regions (ex. US to EU), even between brans (ex. Skoda to VW).
