RetroN 5 may be restored to its factory state by performing the following procedure. You will need an SD card for this, and during the procedure all current data on the SD card will be erased. Perform the steps as follows:
  1. Obtain a spare SD card with a capacity of at least 512MB
  2. Download and install the Win32 Disk Imager application from here: http://sourceforge.net/projects/win32diskimager/files/latest/download
  3. Download the RetroN 5 v0.2.2 firmware "full reset" image from here: http://www.retron5.in/downloads/boot-recovery-SD-fullreset-v0.2.2.zip
  4. Extract the contents of the attached .zip file to obtain boot-recovery-SD-fullreset-v0.2.2.img
  5. Connect the SD card to PC and launch the Win32 Disk Imager application (some versions of Windows will need to Run as administrator)
  6. In the imager app, select the device/drive corresponding to the SD card (ie G:\), and MAKE SURE IT IS THE CORRECT DEVICE - you don't want to erase the wrong HDD. If you have any other removable devices connected to your PC, we advise you to remove all except for the RetroN 5 recovery SD card before starting this procedure; then there will be no way to accidentally erase the wrong device. For image file, navigate to the boot-recovery-SD-fullreset-v0.2.2.img file extracted previously

  7. Select "Write", then "Yes" to confirm. Once the write is successful, use windows "Safely remove hardware" to eject the SD then physically remove the SD from your PC

  8. Make sure the RetroN 5 unit is powered off. Insert the SD card into the RetroN 5 unit, then power it on. It should at this point boot into Retron 5 Recovery System
  9. Using a wired controller to navigate the menu, select Update rkimage from external storage
  10. The software will begin to update your system firmware. When this process has completed you will be returned to the menu screen, and you may see some yellow text indicating that the update has completed

  11. Once again using a wired controller, select Wipe data/factory reset and then on the following screen, select Yes -- delete all user data

  12. You will see yellow text indicating that the data wipe is complete, and you will be returned to the menu. At this point, REMOVE THE SD CARD from your RetroN 5 unit
  13. Use your wired controller to select Reboot system now

  14. The unit will restart and should now be in working order. If problems persist, please contact our technical support staff. 
  15. You must now perform a full format on your SD card in order to remove the RetroN 5 recovery mode data from it; failure to do so will result in recovery mode being activated if the unit is booted with the SD inserted.
  16. Download the "SD erase" image from here: http://www.retron5.in/downloads/sd-erase.img
  17. Connect the SD card to PC and launch the Win32 Disk Imager application, as you did previously for step 5
  18. In the imager app, select the device/drive corresponding to the SD card (ie G:\), exactly as you did previously for step 6. For image file, navigate to the sd-erase.img file downloaded previously

  19. Select "Write", then "Yes" to confirm. Once the write is successful, use windows "Safely remove hardware" to eject the SD then physically remove the SD from your PC
  20. After the SD has been removed from the PC, re-connected it back to the PC
  21. You should see a dialog like this, saying that the SD card must be formatted. Click Format disk

  22. You will see a dialog like this. Ensure that Quick Format is ticked, and click Format

  23. The SD card will be formatted. Once this has completed, use windows "Safely remove hardware" to eject the SD then physically remove the SD from your PC. Your SD card has now been reverted to a usable state.
