  Instructions on firmware:

  1. Before the firmware must make a backup. Music, photos, etc. we copy to removable media or a memory card (it is not necessary to remove a memory card when flashing, but, in order to avoid possible troubles, this can be done).
     
  2. Download the archive with the files of the firmware, flasher and drivers on the computer (PC).
     
  3. The firmware is carried out on computers with the operating system (OS) Windows 7 or 8 (8.1).
     
  4. If you have Windows 8 (8.1) OS, then the drivers should be installed automatically (drivers are needed only for Windows 7 OS, if Windows 8 (8.1) OS is installed, then immediately open the firmware and flash it). On Windows 7, the driver must be installed from the previously unpacked folder "Drivers"Drivers.rar(30.27 MB)
     Only the driver package from the "simpleio" folder may be installed, others may not be installed. It may not be possible to install for a long time, but it will eventually be established. It may be necessary to first remove all already installed drivers, incl. and Nokiev. In addition, NET Framework 4.0 (or higher, for example 4.5.2) must be installed.
     
  5. Unpacking the archive with the firmware on the PC (for example, unpacking files from "FW psp8400duo_1068.0012.0010.0004.part01" to "FW psp8400duo_1068.0012.0010.0004.part14" in the sequence 1,2,3 ... 14, as a result of which a folder will appear "FW psp8400duo_1068.0012.0010.0004" with four firmware files and a flasher).
     
  6. Turn off the device, remove the battery and insert it back into the device (but maybe it will not be necessary).
     
  7. When the device is turned off, we simultaneously hold down the volume up key and the power key.
     
  8. After the vibration, release the power key and wait for the lightning and gear to appear on the screen, then release the volume increase key.
     
  9. We connect the device to the PC via a USB cable.
     
  10. Go to the unpacked folder with the firmware and flasher files (for example, "FW psp8400duo_1068.0012.0010.0004" with four files) and double click on the file "ffutool.bat".
      
  11. In the DOS window ("blue window") that appears, you are prompted to press any key, press any key on the PC.
      
  12. If everything is in order, then the process of firmware in the form of displaying percentages will go on.We do not touch the PC, device, USB cable, we do not interrupt the process !!!
      
  13. We are waiting for the end of the firmware, the DOS window should become "green" and the inscription in the "PASS" window will appear. The whole process takes 5-10 minutes.
      
  14. Disconnect the device from the PC. We take out and insert the battery back into the device, turn on the device (but maybe it will not be needed, the device will reboot itself and turn on).
      
  15. We reset to factory settings.
      
  16. The rollback occurs with the specified firmware (1068.0012.0010.0004) to the firmware version 8.10.12393.890. Next, do a search and install updates. The latest firmware version with updates for the moment is 10/08/14226.359.
      
  17. Next, configure the device for a new one. Recovering from a backup (the desktop may not be restored), download cards, etc.
