The fw_all.bin is a component of the GCD or RGN firmware file and is the only component patched when you patch a GCD file anyway. Just follow this:

  • Open the IMGPatcher then follow the first line in the GUI window ("Drop your ....etc." ignore the second line about adjusting the firmware version, that's not needed when flashing with an RGN file which is what you'll need to with your device).
  • Once you have DriveandDriveSmart40_50_590.gcd loaded (it doesn't need to be renamed to GUPDATE.GCD but you can if you want to do so) the application will immediately start processing the file and create a new file in the same directory (folder) as the original one, it will have '_Patched" added at the end of the file name.
  • Load the patched GCD file into RGN_Tool.exe then press the "RGN" button (middle of the 3 adjacent to File Drop Zone), it will prompt you to save the new RNG file but first override the default name to 226701000590.RGN only before saving in a suitable location.
  • Open Updater.exe by draging 226701000590.RGN onto it's icon or Updater.exe itself, select the Radio Button next to "USB Device" and leave the GUI open and visible on your desktop.
  • Ensure the device is fully OFF. If necessary hold the power button down for between 10 and 30 seconds until the screen goes completely blank.
  • Plug a 'known-good' USB cable directly into a REAR USB2 port of a desktop PC or a USB2 port of a laptop (no hubs, front desktop ports or USB3 ports).
  • Hold device screen firmly in appropriate place while plugging in the cable to the device's USB socket, watch the window adjacent to 'USB Device' for the device details to appear.
  • IMMEDIATELY you see the window populated either hit the enter key on your computer or click the OK button on the GUI.
  • Keep holding the device screen firmly until the flash finishes or at least until to you see 'Loader' or 'Software Loading' (or similar) appear on the device screen.

Your device should now be patched to accept unlocked maps. Provided you don't load original firmware again, in the future you can simply load a patched GCD rather than having to use an RGN and Updater.exe to uprade to a new firmware version.

Ask before proceeding if anything is unclear and please be aware that as i have no control over how you do this in practice that you must assume all risk. The directions i've given you are as correct as they are detailed however.
