DAEWOO DVG-4000S


IMPORTANT: This page is for the Daewoo DVG-4000S ONLY.
It is
NOT for the other Daewoo "4000" model(s),
such as the DVD-4000.


If you have a Daewoo DVD-4000, you may wish to visit the page for the
Daewoo DVD-5700 or Daewoo DVD-5800. It has been reported that the DVD-5700/5800 firmware works on the DVD-4000; however, if the 4000 has 6-channel output, loading the 5700 or 5800 firmware may disable the 6-channel output, since the 5700 and 5800 players
have only 2-channel output.


This page explains how to make your Daewoo DVG-4000S region-free
and Macrovision-free.

You would want to make your player region-free so that you can play DVDs bought from
anywhere in the world -- not just those in your "region".

You would want to make your player Macrovision-free if you have to hook it up through a VCR(or a projector) and the picture constantly fades in and out.
This upgrade gets rid of the fading.

IMPORTANT: If you are hoping to make copies of your DVDs from your player to digital recording sources (i.e. a digital camera or a digital video recorder), YOU HAVE COME TO THE WRONG PLACE! The firmware upgrades available on this page DO NOT disable the digital copy protection that prevents this sort of copying. Digital recording is protected by something known as CGMS/A -- this is DIFFERENT from Macrovision!


If you just need to switch the region setting of the Daewoo DVG-4000S,
this can be done with the remote control.
See SECTION 1 below.

However, if you would like to disable Macrovision, you will need to upgrade the player's firmware via CD-R or CD-RW.
See SECTION 2 below.


SECTION 1: Changing the region setting with the remote control

1. Make sure that there is no disc inside the player.

2. Push the following buttons on the remote control:

SETUP
Stop
|<< (Skip Back)
>>| (Skip Forward)

If this does nothing, try the following instead:

SETUP
Fast Forward >>
|<< (Skip Back)
>>| (Skip Forward)

If this does nothing, try the following instead:

SETUP
|| Pause
|<< (Skip Back)
>>| (Skip Forward)


This should reveal the "FACTORY CONTROL PAGE", pictured below:

Change the region setting as needed.

NOTE: "RCE"-coded DVDs may not play if the REGION ID is set to BYPASS; if you find that this is the case, then set the REGION ID to match the region coding of the RCE disc.


SECTION 2: Upgrading the firmware to disable Macrovision

1. Download the patched firmware by clicking HERE.

IMPORTANT: At this time, the firmware should be considered "experimental", as the supplier does NOT own a 4000S. The firmware should be "safe" to load onto your player, but whether it actually turns off Macrovision is still unknown. If you choose to load this firmware, please report your findings at the
Daewoo forum.

2. Unzip the files -- BANK30.ROM and TEST20MB.TXT

3. Open your CD burning program. Perform the steps necessary to set up
the process of creating a new data CD.

4. Burn BANK30.ROM and TEST20MB.TXT to a blank CD-R/CD-RW.
Be sure to apply these specifications before burning the disc:
Data CD, ISO9660, Mode 1, "Close"/"Finalize" disc session.


(Note: you may wish to place the ROM file inside of a subfolder on the disc.
This prevents the upgrade from starting automatically.)


(If you need help with burning the disc, you might want to check out this excellent article put
together by the guys at Area 450. The article references Sampo firmware, but the burning
specifications are basically the same. Note that the article does NOT make any mention about
creating a subfolder, or closing/finalizing the disc, so you will need to figure
out those steps on your own.)

5. After the disc is burned, view the contents of the disc in Windows Explorer/My
Computer/whatever. Right-click on the BANK30.ROM file that's burned on the disc and select "Properties" (or do whatever is necessary to view the Properties.) Make sure that the file size is
EXACTLY
524,288 bytes.
If the file size is NOT 524,288 bytes, DO NOT CONTINUE!

6. Read the disclaimer:

DISCLAIMER: USE AT YOUR OWN RISK. I DO NOT OWN THIS PLAYER SO I CANNOT TRY THIS CDR UPGRADE MYSELF. I WILL NOT BE RESPONSIBLE FOR ANY DAMAGE THAT MAY
RESULT TO YOUR PLAYER. PERFORMING
THE PROCEDURE DESCRIBED HERE WILL SURELY
VOID THE WARRANTY OF YOUR PLAYER!


7. Eject the disc tray on the DVD player.


8. Push SETUP. Enter the PREFERENCES menu. Scroll down to the DEFAULTS option. Select the RESET option and push PLAY. Then push SETUP to exit the menu.


9. Put the CD-R/CD-RW, data side down, on the tray.


10. Close the disc tray.


11. The upgrade process will now begin.

(Note: If you placed the .ROM file inside a subfolder, the file browser menu will appear -
use the arrow keys on the remote to select the folder and then push ENTER or PLAY.)

IF YOU SEE THE MESSAGE "WRITE FAIL" at this point,
scroll down to the "WRITE FAIL error" section
towards the bottom of this page!

DO NOT DO ANYTHING UNTIL THE DISC TRAY HAS AUTOMATICALLY EJECTED.

You should see the following screens (probably WITHOUT the strange colours),
in this order:

DO NOTHING AT THIS POINT. LET THE UPGRADE PROCEED.

DO NOTHING AT THIS POINT. LET THE UPGRADE PROCEED.

"WRITING" (which comes on and off about 3 times) and "BANK30.ROM" appear on your TV screen
(sorry, no picture available)

DO NOTHING AT THIS POINT. LET THE UPGRADE PROCEED.

**DO NOT TURN OFF THE POWER YET!!!**

12. Once the upgrade is complete, the screen will go blank, the LCD display's characters should disappear, and the disc tray should automatically eject. Remove the disc.

13. Then, turn OFF the power using the MAIN POWER SWITCH
(on the back of the player) -- NOT the remote control or front panel power button.

14. Wait at least 30 seconds. Then, turn ON the power using the main power switch (not the remote control or front panel power button.) The disc tray should automatically close.

15. Push SETUP. Enter the PREFERENCES menu. Scroll down to the DEFAULTS option. Select the RESET option and push PLAY. Then push SETUP to exit the menu.

16. The firmware upgrade is now complete. Macrovision should automatically be disabled, and if you check the region setting (see Section 1), you should find that the setting is now on BYPASS (even if you had it set differently prior to the upgrade.)
You can change the region setting if you wish.

Please report whether or not Macrovision is disabled at the
Daewoo forum.


RETURNING TO THE
ORIGINAL (FACTORY) FIRMWARE

Download the original (factory) firmware HERE.

Repeat steps 2 through 16 in Section 2, above.


WRITE FAIL error

While performing the firmware upgrade, if you see the message "WRITE FAIL" on the screen, you will need to replace the firmware chip inside the player.

Details on ordering a replacement chip are available HERE.

You can also order a firmware chip at a very reasonable price from
chipdlx@yahoo.com

Regardless of who you contact to get the chip, specify that you need an "AMD 29f040 or compatible" 32-pin DIP chip, programmed with the firmware located HERE.

Once you receive the replacement firmware chip, you can visit THIS PAGE for instructions on how to properly pop out the old chip and put in the new one. The chip that you'll be replacing will look similar to the one outlined by the red box in the picture below:
