info

Thanks to -XTR3M3- for creating the base for this how to and Yalmac for translation. This article is based on this work, but not linked in any way directly to the original author.

warning

Patch files are different for each FW version. Make sure that you use the correct patch files for your unit.

tip

Before reading this, check SD Activator by Congo & Duke.

How do I recognize a MST2 Delphi Unit?​

  • Delphi Units are always standard devices (MST2) and not high (MHI2) devices.

  • Accordingly, a Delphi unit is always a MIB2 Discover Media or MIB2 Composition Media and not a Discover Pro type unit.

  • All Delphi Units are Discover Media or Composition Media devices. But not all Discover Media and Composition Media devices are Delphi Units! It can also be a Technisat/Preh unit.

  • To recognize the unit without removal, it is necessary to hold down the MENU button on the radio for 3 seconds to open hidden service mode. In this menu go to Software Update/Versions and check SW Train.


    Service mode available after holding MENU button for 3 seconds. SW Train example with European Volkswagen firmware.

  • Delphi SW Train Version scheme example: MST2_EU_VW_P0891D.

    \n

info

If there is a D at the end of your SW Train version, you have a Delphi Unit.

tip

If you see a PQ or ZR after the vehicle brand or a T at the end in your SW Train version, then you have a Technisat Preh Unit.

Requirements - What do you need?​

  • Delphi MST2 unit,
  • Diagnostic tool to enable Developer Mode (VCDS, VCP, OBD11…),
  • Quality SD card (how to test SD card),
  • Ethernet-USB adapter supported by the unit (D-Link DUB-E100 or alternative),
  • Ethernet cable,
  • Patch files from mibsolution.one.

Network settings​

Software-Version​

info

The patch files are different for each SW-Train and software version! \n Therefore, make sure that you use the right patch files for your unit!

warning

If you use the wrong patch files, you will brick your unit in the worst case!

info

In addition to the SW-Train mentioned in the first section, there is also the software version, which can be read at the end of the same menu item.

Activate Developer mode and GEM​

Activate the Green Engineering Menu (GEM) with VCDS, OBDEleven, VCP, or any other diagnostic interface.

Check: 5F - Enabling Developer Mode and Hidden Menu for more details.

Update FW

info

Train**In the ~~08xx~~ series, the firmware updates have not always been released ascending order.

The ~~0891~~ is not the latest firmware, but ~~0879~~ is!

P9122D (MU0842) ➔ P0867D (MU0867) * ➔ P0890D (MU0890) ➔ P0891D (MU0891) ➔ P0876D (MU0876) * ➔ P0879D (MU0879) **

* = Telnet is not activated on this FW

**= there is a modified firmware (MST2_EU_VW_P0879D-wTelnet) on the mibsolution.one server with telnet activated. Read in the folder oft this FW: patch\howto.txt !!!

tip

Downgrade/upgrade to a version supporting telnet and or having an available patch

Run FW update​

  1. Format SD card to FAT32.

  2. Copy firmware update files to the SD card.

  3. Insert the SD card into the SD card slot 1.

  4. Remove all other SD cards and USB devices!

  5. Press the MENU button on the radio longer until another (service) menu opens. Select the test mode there.

  6. Switch to the "SWDL" category.

  7. Activate Software Download Manual Download and tap "Start Download".

  8. Select source (SD card), select everything and start firmware update.

warning

What should be considered when updating the firmware?

• Leave the ignition on

• Turn off unnecessary consumers (lights, ventilation, ...)

• Connect charger(at least 15A charging power, better 20A and more)

• Depending on the unit (RAM/CPU), the update takes 20 to 60 minutes

Fix Software Version Management (SVM) error​

Use VCDS / OBDEleven / VCP to clear the erroro from unit.

TELNET Connection

tip

Ethernet must be activated in GEM to enable telnet access.

Enable ethernet​

Hold down the MENU button on the radio until the Service menu appears.

Navigate to Testmode

Select Green Engineering Menu

(optionally you can also get there directly by pressing the MENU button for a very long time)

Change to the category "debugging mlp"

Check Ethernet box and restart the unit (hold down the power button for at least 10 seconds)

After the unit has been restarted enter same menu again and also check Switch to MLP must be checked. (Note: If only removing CP, it does not seem MLP needs to be selected 8/7/2023)

Connect with Putty - Telnet​

Now the USB-LAN adapter can be connected to the USB port in the vehicle and connected to the laptop via LAN cable. If the LEDs othe adapter light up, if the cabling and network configuration on your PC/notebook are correct.

Putty can now be started.


The IP address is taken from the GEM menu debugging mlp.

IP 192.168.1.4  and port 23 are default on all units.

Click open to connect to unit

If everything has been configured correctly, you can tell from the QNX Neutrino login message that it worked.

Only the word root (NO password) is required as a login to Delphi units.

As soon as Welcome is shown, commands can be entered.

Patch unit

Common shell commands:​

  • cp = copy
  • rm = delete
  • chmod = change rights (e.B. chmod 777 = full read/write permissions)
  • mkdir = create directory (folder)
  • mount = mount path
  • umount = unmount path
  • && = execute another command

Attributes:

  • -f = force (overwrite / force)
  • -R = recursive (e.B. copy/delete folder including contents and subfolders)
  • -t = mount request / special type (e.B followed by qnx6)
  • -u = update (remount)
  • -V = progress indicator
  • -w = read/write permissions (when mounting)

Create backup - recommended​

warning

It is important to create a backup before starting to patch!

Insert empty the SD card into SD 1 port and execute the following commands via putty.

Enter the commands exactly!

Unintentionally set spaces can lead to bricking of the unit!

This note is especially relevant for users who use a translator because they partially insert unwanted spaces.

Manual input​

  1. Mount SD card

    cd / && mount -uw /sdc1/

  2. Create backup folders on the SD card

    mkdir /sdc1/backup/

SWaP (FEC) patch​

info

This patch is required to disable the verification of the signature of the FEC containers. \n Open MIB2 Delphi FEC Generator  by  XTR3M3 and select the appropriate featureenablecodes as desiredand thencreate/save the FEC container (right button). The VCNR and VIN can either be entered manually or imported from an existing (backup) FEC container.

However, an already patched FEC container can also be easily changed with your VCNR and FIN.

This *.fec  file and patched  SWaP  will be copied to SD card and insert it into slot 1 of the unit.

First, the patched SWaP file is copied to unit.

warning

Enter the commands exactly! Unintentionally set spaces can lead to bricking of the unit! This note is especially relevant for users who use a translator because they partially insert unwanted spaces.

Config (CID) patch​

info

This patch disables SD card check for navigation (aftermarket SD cards).

warning

Enter the commands exactly! Unintentionally set spaces can lead to bricking of the unit! This note is especially relevant for users who use a translator because it can insert unwanted spaces into the translated text..

This script can be copied to SD card or just executed by typing

grep -v "MIBST" /extbin/apps/cfg/MHConfig.cfg > /tmp/MHConfig.cfg && cp /tmp/MHConfig.cfg /extbin/apps/cfg/MHConfig.cfg && sync

delphibin.ifs (CP) patch​

info

This patch disables component protection check

warning

Enter the commands exactly! Unintentionally set spaces can lead to bricking of the unit! This note is especially relevant for users who use a translator because it can insert unwanted spaces into the translated text.

  1. Copy patched delphibin.ifs that corresponds to Train and unit type onto the root of SD card

  2. Insert SD card into SD 1 slot of the unit.

  3. Create backup of the original delphibin.ifs: \n cp -Vfr /extbin/apps/bin/delphibin.ifs /sdc1/backup_delphibin.ifs

  4. Copy patched delphibin.ifsto the head unit: \n cp -Vfr /sdc1/delphibin.ifs /extbin/apps/bin/delphibin.ifs

  5. Sync file system:

    MountPathSync /extbin/apps

  6. Restart the unit
