Getting Started

After downloading and installing MHD Flasher for your vehicle, the next step is to open the app and sign in.  Android Note: the first time you launch the app you will see a permissions popup window which you must hit OK for (this grants MHD file permissions, which is required for saving logs and DME info, as well as loading custom tunes, etc).

If you are a new user, the login process is very straightforward and there is nothing you need to do prior.  However, if you previously had MHD licenses and want to ensure they get transferred correctly, some preliminary steps for this will be detailed in the “Existing Licenses” sub section below.

Logging In

The first time launching the MHD app, you will be greeted with the following screen.  We automatically open the side navigation slide out for you to show that you should want to log in.  If you accidentally close this slide out menu, you can open it again by clicking the “hamburger icon” in the top left corner of the app home screens.  The icon looks like this:   ☰

Open

Android Note: Google Chrome is required to be installed and NOT deactivated on your device.  Without it, the login process will not work correctly and you will be unable to log in.  Please ensure it is installed and active before proceeding.

Make sure you are connected to the internet, and then click the MHD LOGIN button.  Please read the text carefully in the popup prompt, and click OK to proceed to the browser window.

Android Note: If you have multiple browsers installed, your device should prompt you to choose which one you would like to proceed with.  Make sure to select Google Chrome.

On the login screen, you will see a few different options.  What you choose is entirely up to you, but there are some advantages to each.  The choices can be broken into two groups:

Open

Social Login Options

These are the top three buttons you see: “Continue with Facebook”, “Sign in with Apple”, and “Continue with Google”.  If you already use any of these services and do not want to have to create / remember another username and password combo, then you will want to choose this option.

MHD Account

This is an entirely new account you will create on our servers.  This login method is convenient if you wish to later share your login with a Pro-Tuner. To create an account, click the “Sign-up now” link at the bottom and follow the on screen instructions.

After completing the sign up form, you will get a confirmation email sent to the email address you used.  You must open this email and click the “verify email” link before you will be able to log in with it.

Android Note: If you were a previous user of the old Android app, this is NOT the same as your Google login.  Do not try to enter those credentials into these MHD Account textboxes as it will not work.

ATTENTION:  All of your licenses will be tied to the login method you choose here, so please select carefully!  If you log out and log back in with a different method, you will not see your licenses and may lose them!

After logging in, you will be taken back to the MHD app home screen, with a loading image indicating that your licenses are being updated.  If you did not have any existing licenses, this should quickly close.  If you did, you can see the progress as it transfers each license one by one to our new license server.

Existing Licenses

If you previously used the old MHD Android app and your licenses did not transfer properly to our new license server (for use with the updated app), please follow these steps very closely on an Android device:

1. Uninstall MHD App

2. Go to Settings > Accounts and ensure there is only one Google account present

   1. This Google account must be the one you originally purchased your MHD licenses with

   2. Remove all other Google accounts

3. Long press on Play Store icon > Info > Storage > Clear Cache

4. Open the Play Store app, and ensure the Google account pictured in the search bar is the account you originally purchased your MHD licenses with

5. Install MHD App

6. Launch MHD App and login

Cross Platform Licenses

Thanks to the switch over to our new custom license server, all of your MHD licenses will be accessible on any device you own, whether it be Android or iOS.  Just make sure you login with the same method you used when initially setting up the new MHD app.

Purchase New Licenses

All new license purchases are now done through our online webshop / store, available here: MHD Tuning > Shop > then select the car series / engine you wish to purchase a license for.

This will land you on the “Super License” page for that engine / vehicle.  The Super License includes ALL current individual licenses available for that engine / vehicle at a discounted price.  If you do not wish to purchase the Super License, and instead are just looking for an individual product like Flasher, Logger, or a Map Pack, simply scroll to the bottom of the Super License page and click on the one you want.  After adding all the items you want, proceed to the cart and purchase!

ATTENTION:  Your license keys will be emailed to the email address you enter during checkout.  Please ensure that you typed the email address correctly and that your mailbox is not full.  There is also a chance the email you receive will go to the SPAM folder or PROMOTIONS on Gmail, so be sure to check those as well.

Activate License Keys

In order to activate one of your newly purchased license keys, you must have connected at least once previously to your car so MHD can read your VIN.  If you use MHD for multiple vehicles, make sure the last vehicle you connected to is the one you wish to activate the license key for.  For more information on this process, see the section “Connecting to Car” below.

Your order confirmation email will contain a section at the top that looks like this.  You must click the “License Key” button.

With the license keys in hand, you now will want to open MHD, make sure you are logged in, and click the ☰ icon to expand the side menu.

Click on “My Licencses” followed by “Activate License Key” once the My Licenses screen loads.

Once you have finished, you should see all of your licenses, grouped by vehicle VIN.  If you have licenses for a vehicle of a different series (like E series N54), but have the F+G series app open, you will still see them all listed here.
