Flashing my DVD drive

I have a Mat*!@:a DVD installed in my laptop:
UJ-820S 1.50

I would like to flash the firmware.

But, I have no changes left. Would flashing it provide me with more changes available?

Driveinfo.exe says:
User: 0 changes left
Manufacturer: 4 changes left
Status: fixed, cannot be changed

"Would flashing it provide me with more changes available?": No.

You may be able fo find a region free hack for it, but flashing the firmware with a vendor approved upgrade won't do that. You risk making the drive unusable if it goes wrong.

Region setting
There are actually up to 3 region protections on a system:
- 1 in the DVD drive
- 1 in the Operating System (windows) - More info on Windows region management.
- 1 in the software player (eg. WinDVD, PowerDVD...)

When you flash your drive with a region free firmware (RPC-1), you remove the region counter from the drive itself completely, but with this counter gone, the software counters kick in to replace the one from the DVD drive. This means that you still have these other 2 to defeat!!!.
An alternate region free solution that is available for some drives is known as an "Autoreset" firmware: Instead of removing the counter from the drive completely, the counter simply resets itself to an unlocked state when the computer is restarted. This way, the drive appears as region protected (RPC-2) but the counter can be changed indefinitely. Creating autoreset patches is slightly more difficult for the patcher, but makes the life of the user easier because DVD Genie and Region Killer are not required as they are for RPC-1 firmwares.
On the other hand, it's easy for software manufacturers to detect autoreset firmwares, and if they decide to do so, you will still need a software patch in the long run. This is why RPC-1 firmwares are seen by most as the long term solution.

So, unless a program like DISCInfo click here or Drive Region Info tells you that your drive is still protected or you used an autoreset firmware, your drive IS region free, and any region counters that you still see come from software region settings.

To bypass that, you need to use programs such as DVD Genie click here or DVD Region Killer click here (the later is highly recommanded).
