How to apply: buttons on front panel and remote control.
The 7 0's hack and others listed for this model on the "lock icon" did not work on my LG-DR1F9H (although the 1397139 hack did give me the firmware version info and reset my settings to factory defaults).
So while discovering the way to disable cprm, I ran across the settings for region code in the same area. I changed them both at once using these steps.
CAUTION: These steps take you into a hexidecimal editor where values are changed with the up/down arrows on the remote. DO NOT hit the up/down arrows on your remote until you have FIRST written down the current values (just 8 2-digit hex numbers) which appear when you first get into the hex editor.
1) While the player is on, press and hold both up- and down- channel buttons on the recorder for about 5 seconds (^ & v).
2) A hex editor screen will appear with 8 "OP" codes. The second word in each of these lines is a 2-digit hex number. WRITE THESE DOWN BEFORE YOU HIT ANY BUTTONS ON YOUR REMOTE CONTROL, in case you need to restore them.
3) To disable CPRM, use ONLY the right arrow on your remote (>) to highlight the rightmost digit of OP code 4. Use the up and down arrows on your remote to change this number to it's present value MINUS 8 (if the digit is an A,B,C,D,E,or F; the number is 10,11,12,13,14,or 15, respectively; ie- change a D to a 5). You are in effect clearing the high-bit in this hex digit.
4) To set region 0, use ONLY the right arrow on your remote (>) to highlight the leftmost digit of Op code 6. If this number is 8 or 0, you are already region 0. If this number is greater than 8 (including A,B,C,D,E,F), then change it to 8. If this number is less than 8, then change it to 0. This simply clears the low 3 bits in this hex digit.
5) If you think you might have changed something you shouldn't have, then you can ABORT by hitting the menu/list button on your remote.
6) If you are satisfied with your changes, then hit Enter on your remote to write the new values to ROM. Then hit menu/list to exit.
When you turn your DVD player back on, it will play DVDs of all nationalities and will not prevent recording of CPRM-limited video onto a DVD.
