Comparing to the previous official release version BDP83-31-0620, the major changes included in this version are:

1. Blu-ray Disc compatibility improvement, especially for certain titles such as "X-Men Origins: Wolverine", "Lie to Me", "Dollhouse Season 1", "12 Rounds" and "The Haunting in Connecticut".
2. Additional "Deep Color" options utilizing dithering. If the display does not support 36-bit deep color, dithering 36-bit to 30-bit or 24-bit may produce an image that is visually smoother than rounding 36-bit to 30- or 24-bit.
3. Improved precision for color space conversion.
4. Improved up-conversion for MKV files that have a picture size smaller than 1280x720 with 24fps frame rate.
5. Improvement for DVD-A disc compatibility.  The specific titles targeted include "Beck: Sea Change" and DVD-A discs released in Japan by JVC.
6. Improvement for DVD navigation.
7. Improvement for compatibility with Denon receivers that only acquire 2ch DSD signal upon initial playback of a SACD multi-channel disc.
8. Improvement for compatibility with receivers that show "no signal" but play audio when a CD is played using HDMI bitstream output mode.
9. Fix for the issue of subtitle being cut off when playing a PAL DVD.
10. New pop-up user interface for audio and subtitle selection.
11. Improved GOTO function for music file playback.  The GOTO function now allows the user to jump to a certain time point within a music file.
12. Other general disc compatibility and performance improvements. The specific titles targeted include the CD "The Saturday Nite Agenda", DVD "IL DIVO - Live at the Greek Theater", Blu-ray "Fired Up" and a few other discs.

All features and improvements of the previous firmware are also included in this version. If you are upgrading from the BDP83-36-0805 version, please read the note below.

Warning: Although firmware upgrade is an easy and usually trouble-free process, it is important to ensure that the power supply to the player is stable, and the upgrade process is not interrupted. A failed firmware upgrade can render the player unusable.

There are three ways to upgrade the firmware. If your player has an Internet connection, the easiest way to upgrade the firmware is the "Via Network" method. If you have a USB thumb drive, you may choose the "Via USB" method. You can also use the "Via Disc" method by preparing a firmware upgrade CD yourself or requesting a firmware CD from OPPO customer service. Please follow one of the three procedures below based on the upgrade method chosen.

Firmware Upgrade via the Internet

1. Turn on your TV display and the OPPO player. Make sure that there is no disc in the player and the player is not playing any content from a USB device.
2. Press the SETUP button on the remote control to enter the setup menu. Select Device Setup, Firmware Upgrade, and then Via Network.
3. The player will start searching for the new firmware from an OPPO firmware server. Please follow the on-screen instructions to complete the firmware upgrade process. Use the remote control to respond to on-screen prompts. Do not use the front panel buttons because the front panel buttons will stop working during the upgrade process.
4. DO NOT ATTEMPT TO TURN OFF THE PLAYER, UNPLUG THE POWER, OR PRESS ANY BUTTONS OTHER THAN NECESSARY TO RESPOND TO THE ON-SCREEN PROMPT DURING THE REMAINING UPGRADE PROCESS.
5. In order to complete the firmware upgrade process, the player will turn off automatically.
6. Turn on the player again after the firmware upgrade process is completed. Repeat from Step 2 above until the player reports that it already has the latest version. This will ensure that the player downloads and installs all parts of the firmware update.
7. Check the new firmware version by going to the setup menu, and then selecting Device Setup - Firmware Information. Early production models (not sold to retail customers) do not have an upgradeable MCU so the MCU firmware upgrade will fail. This is normal for units with serial number "E202..." .
8. (Optional) From the setup menu, select Device Setup, Reset Factory Default, and then choose OK to reset the player settings. Enter your customized settings as necessary after resetting.
9. Congratulations! You have just completed the firmware upgrade.

Firmware Upgrade via a USB Thumb Drive

1. Click here to download the firmware file BDP-83-40-0925.zip
2. Insert a USB thumb drive to the computer that stores the downloaded zip file, and unzip the firmware file to the USB drive. Verify that the USB drive now contains a UPG folder, and inside the UPG folder there are files BDP-83.bin, DVD.BIN, DVD430.BIN and MCU83-1.BIN.
3. Remove the USB drive from the computer.
4. Turn on your TV display and the OPPO player. Make sure that there is no disc in the player and no other USB device is connected to the player.
5. Insert the USB drive containing the firmware file to a USB port on the player's front or back panel.
6. The player usually can recognize the firmware file and prompt you for firmware upgrade. In case the player does not prompt you, press the SETUP button on the remote control to enter the setup menu. Select Device Setup, Firmware Upgrade, and then Via USB.
7. Please follow the on-screen instructions to complete the firmware upgrade process. Use the remote control to respond to on-screen prompts. Do not use the front panel buttons because the front panel buttons will stop working during the upgrade process.
8. DO NOT ATTEMPT TO TURN OFF THE PLAYER, UNPLUG THE POWER, OR PRESS ANY BUTTONS OTHER THAN NECESSARY TO RESPOND TO THE ON-SCREEN PROMPT DURING THE REMAINING UPGRADE PROCESS.
9. In order to complete the firmware upgrade process, the player will turn off automatically. Unplug the USB drive after the player turns itself off.
10. Turn on the player again after the firmware upgrade process is completed. Check the new firmware version by going to the setup menu, and then selecting Device Setup - Firmware Information. If you notice that the firmware versions displayed do not match the versions listed in this release note, please retry the firmware upgrade procedure from step 4 to ensure all parts of the firmware package are installed. Early production models (not sold to retail customers) do not have an upgradeable MCU so the MCU firmware upgrade will fail. This is normal for units with serial number "E202..." .
11. (Optional) From the setup menu, select Device Setup, Reset Factory Default, and then choose OK to reset the player settings. Enter your customized settings as necessary after resetting.
12. Congratulations! You have just completed the firmware upgrade. Delete the UPG folder and its content from the USB drive so you do not accidentally install the firmware again.

Firmware Upgrade via CD
