Connecting to your vehicle
Once you have downloaded xHP on your Android/iOS or Windows 10 device and have acquired the additional hardware needed (see supported flashing hardware), you are ready to connect to your vehicle. This chapter will guide you through the steps needed ANY TIME before attempting to read or flash your vehicle.
Preparing device
Make sure your device has at least 25% battery capacity left.
Set your device to Flight Mode. Bluetooth and 4G/Cellular must be turned off. Especially true when flashing through Wi-Fi connection. (more stable connection)
Cable-Connection: Be sure to grant xHP the rights needed to access the local USB/Lightningport on your device.
Once a flash has started, leave your device alone. Do not move or touch it.
Preparing vehicle
Make sure not to open/close doors during the process. If you want to stay outside during the process, open the side window and operate your device standing next to the vehicle.
Ignition has to be turned ON, Engine OFF.
Make sure your transmission is in “P” position.
Turn off ALL auxiliary devices: Headlights, Interior Lights, Heating, Heated Seats, Radio, NavScreen etc.
Lock your Drivers-Seatbelt before starting the flash! Do not unlock, unless the process is completed! (this keeps the Ignition ON)
Set your device to Flight mode. (only Wi-Fi ON) Incoming calls through Bluetooth will disturb not only the Android device, but your car too.
Make sure you’re only flashing with a good, healthy battery. xHP will refuse to start a flash operation below a certain voltage level.
The car can draw up to 30 Amps during the flash, so we recommend a supply able to deliver at least 30 Amp @ 13,8V. (e.g. Maas SPS-30).
The voltage supply needs to be connected to the terminals in the engine bay. DO NOT connect directly at the vehicle’s battery. A normal battery tender or charger does not help to stabilize the voltage during the process. It can only help to pre- charge the battery in advance.

The very first flash on your vehicle will “Install” xHP on your car (“Long-Flash”). This procedure takes approx. 10 min with DCAN. We highly recommend using a power supply for this first flash. After installing, the following flashes will take no more than approx. 2 minutes. These subsequent flashes can be carried out without a charger, but you do not want to see voltage levels below 12V when starting a flash. It is NOT possible to flash the TCU while the engine is running. |

If you have any piggy-back ECU solutions installed which interfere on the CAN-BUS (like a JB4) be sure to turn them OFF. Also problematic can be:
In certain cases, you probably need to remove them completely from the vehicle before. We recommend you to do so, before using xHP! |
Connecting through DCAN Cable (E, F & G - Series)

Plug in your cable to the OBD port of your vehicle. The OBD port is located in the drivers footwell on the left side.
Connect the OBD/DCAN cable with your USB OTG Adapter.
Unlock your Android device.
Connect the USB/OTG adapter to your Android device and wait for the USB permission screen to pop up. Please make sure that you’re granting permanent access rights to xHP in this screen. On some Android versions, the screen will only appear after startup of xHP. Wait a few seconds after connecting the USB OTG cable.
Start xHP and after creating an account and logging in, hit the Connect Button.

Most Android devices will prefer Wi-Fi connections over 4G/LTE. As soon as you connect to the Wi-Fi network created by the Thor or MHD Wi-Fi Adapter, you will no longer be able to access the internet, even if cellular is still turned on. Therefore, the initial vehicle unlock requires a special procedure when using the Thor or orange MHD Wi-Fi Adapter:
Very first start: Start with Internet, so not connected to the wireless Adapter Wi-Fi. This is only true for the very first startup. Not needed afterwards.
Plug in your Wi-Fi Adapter into the OBD port and wait 10-20 seconds. Connect to the created Wi-Fi on your device. Press Connect in the App. The App will pull the necessary data from your car, to perform the Online Support-Check.
Disconnect from the Adapter Wi-Fi. You can now perform the Online-Support-Check and redeem your previously purchased voucher codes. (Codes can be bought at our Web-Shop)
Afterwards you can switch to the Adapter Wi-Fi again. The app has downloaded all necessary data and is now ready for offline use.

Pro tip: on iOS devices you can set the Wi-Fi to be still connected to the internet, even if you are connected to the Wi-Fi adapter . |

Go to WiFi settings and choose the WiFi adapter, then go into the settings, and change the settings to the ones seen on the right:
Click: “Configure IP” - Manual
IP Address: 192.168.4.100
Subnet Mask: 255.255.255.0
Router: Leave field empty
Click “save”

Android users need to configure the Ethernet port, after connecting the ENET Adapter to their devices. Please open the settings panel on your device. Depending on your Android version, the procedure may be a bit different. The screens were taken from a Galaxy S9 phone, running Android 9. This procedure is only necessary on first connect. Your phone will store those settings for subsequent connects. Eventually you need to re-plug the adapter, after saving the settings to take effect.
On Android you need to configure a static IP address:
Connect the cable & press OK
… open Connections, …
… more connection settings”…
… then “Configure” …
… open “Ethernet”…
… and set the below settings
| Note |
|---|
Please check if your device supports the manual setting of a static IP-address, as not every manufacturer unlocks this feature in their version of Android. |

xHP also supports the new ENET wireless adapter from MHD. Just plug in the adapter into your OBD port and connect to the created Wi-Fi named “MHD_xxxx” with the password “MHD_ENET”. No further configuration needed. The Adapter works on Apple and Android devices. ENET is only available on F and G-Series vehicles. There is no support for E-Series cars with this adapter.
Most Android devices will prefer Wi-Fi connections over 4G/LTE. As soon as you connect to the Wi-Fi network created by the MHD ENET-Wi-Fi Adapter, you will no longer be able to access the internet, even if cellular is still turned on.
