Firmware and software updates

npaladin2000 edited this page Dec 30, 2019 · 6 revisions

There are two methods for installing custom firmware, the flash method and the OPK method. The OPK method avoids having to remove the battery, but it's wise to replace the (rather cheap and unreliable) SD card that comes with the device.

There is no OPK release at this time.

(STABLE RELEASE)

[Download Here]

Installation

  1. Copy the OPK to the "apps" directory in the root of your SD card. If the folder does not exist, create it.
  2. After inserting the card into your device and starting, an "OS Update" Icon will appear on your Applications Tab. Open it.
  3. Use the "Start" button to select "Ok" as needed to proceed with the update.
  4. System will reboot. After this point the updater OPK can be deleted.

The latest flash-firmware release (installed by removing the SD card behind the battery) is v026.
