If you click the “Stock” tab, you will see three possible options.
Flash Back to Stock
To flash back to stock, select the tab Stock > Flash back to stock. This option will uninstall MHD and completely revert your DME back to its original factory state. This can be useful if you wish to return your vehicle to stock before selling it, etc. An original backup file is not necessary for this process as MHD can intelligently generate one exactly for you based on unique identifiers in your DME.
ATTENTION: flashing back to stock requires a long write, so a battery charger is highly recommended!
Flash Stage 0 (stock power)
There are two paths to access this function, either through Stock > Flash stage 0, or Tune > Flash an MHD Map > Version (if applicable) > Stage 0. Both paths through the MHD application will do the exact same thing.
With this flash option, the tune and power level will be exactly as it was stock, however MHD will remain installed so you are able to customize flash options if you wish. Additionally, you will be able to data log enhanced parameters specific to MHD. This is useful if you are trying to troubleshoot an issue but still want the enhanced logging abilities.
NOTE: if MHD is already installed and no flash option change triggers a Long Write, this flash should be a short Map Write. As with the above section’s instructions for OTS / Custom map flashes, you should use a battery charger if doing a Long Write or Full Write (first MHD install).
Generate Updated Backup
To generate an updated backup, select the tab Stock > Generate updated backup. This option will create a *.bin file in the MHD root folder which is exactly your OEM software. While this is not necessary for flashing back to stock, it can be useful if you or your tuner needs an original file to start from for your custom tuning.
