Thanks to all, particularly Sango......I was successfully able to update the firmware version of my XP30
Fo my ease, i had collected the various instructions etc posted by different people in this thread to understand the process (very simple process on the hindsight

)
I am pasting all the info in this post below, so others may be able to get it all in one place:
BTW- for those xp-30 and xp-50 owners the way to check your firmware version: Press pause and open ON the UNIT PLAYER buttons simultaneously and hold down, then press 7 on the remote. The LAST 3 digits displayed on the unit LCD screen is your firmware version. This may work for RP82 and other Panny DVD players - others have to confirm that.
***********************************************************
The .rar file is compressed. You have to unzip it and then burn the contents. Sango suggested Blindwrite to burn it. I used it and it worked great.
***********************************************************
You need WinRar to extract the rar files.
Use Blindwrite v4.57 to burn the image.
- use writing method DAO Pw (best writing method)
*************************************************
use winrar to unzip it. then use blindwrite to burn it. When it is unzipped the files are coded as blindwrite files - at least they were for me. Then you open blindwrite search the directory where you unzipped to and it will detect the files. Note - it will only show 1 of the 3 files that you unzipped but as long as all 3 files are in the same directory selecting only the 1 file is fine. Then burn.

Correct you must use Blindwrite 4.57. Blindwrite is one of the best powerful recording tools to use(Alcohol 120% is just as equal). CD-Creator is like nothing compared to Blindwrite, same goes to Nero if you want to do perfect copies (which also include protections).
Settings for Blindread:
Put a check in this checkbox: Extract subcodes(if your reader allows it) <- This is how youm make perfect copies of CDs, because of this!!
Settings for Blindwrite:
Writing mode: DAO Pw
Speed: *Lowest as possibe
**********************************************
As I've mentioned in my thread, use Blindwrite 4.57. The reason is because in the 5, the advanced features which I'm talking about are missing so this is why I specifically mentioned the particular version.
-----------------
Nero can't read BW format, except the the other way is true. Nero can most likely copy if it I made the image using Nero but I don't trust it because it doesn't copy subcodes. It will copy but there isn't any guarentee that it's copied exactly perfectly like the original.
An example would be copying some disc which has a some protection which looks for something at a certain location on the disc. Without subcodes, you can copy fine. However, when it comes to trying to test the disc, you'll end up with a disc which doesn't work and i'll give an error message or saids, please insert the disc etc.... With subcodes, none of that.
--------------------------------------------------
I found two very good tuitorials reguarding the read/write methods using BW 4.57. They are very useful. I remember the BW site originally had it and it's gone.
I suggest that users should read very throrougly through them to fully understand understand Blindwrite and it's features why it makes it a very powerful recording tool.

Note: I aimed the two links intentionally to the writing page to get that question out of the way but you should read from the very beginning afterwards.
This is why in the post, use Blindread - read subcodes and Blindwrite - DAO Pw. Both of these in combination will be the key pointers in making a pefect 1:1 copy. It does mentioned about the SAO mode thing but it's very technical which I don't understand so it should be fine with what I mentioned above.
************************************************************ ***************
For people having problem with Blindwrite 4.57, like myself (my LiteOn CD-RW writer was not recognized by Blindwrite 4.57), use version 5 should be fine, at least for the RP82/XP30 firmware part anyway. Because Sango made the file in version 4 format, be sure to select version 4 format when you are looking for the file in your directory.

It has come to my attention that several users are not experiencing the completed screen when the firmware is done updating as it simply displays a black screen after restarting itself. They begin to worry that their unit is gone which insn't true - the final complete screen seems to have glitched out. I didn't experience the issue with my RP82 or 56 thou.
Another issue is which is occuring is being unable to play the player's own region.
I suggest all owners who upgraded their firmware to perform the reset sequence if they gotten the completed screen or not to eliminate issues which may come up.
Simply take out the firmware disc and power the unit off and on again.
Perform the following:
On the unit
- hold PAUSE + BWD-SKIP + OPEN for about 3 seconds
The display will display initialization
- when initialization is being displayed, let go of PAUSE and press STOP while holding the other two buttons.
The display will then display reset.
This will completely reset the unit and it's back to normal =)
