The Firmware Page

I am SO sorry to bother you! I know that there is already too many topics about this problem. And for two days i have been searching and downloading all programs i thought could help me with my question. Just when i think i will be able to solve the problem, something different comes up and I'm stuck.
Here is what do i have :
Vendor: HL-DT-ST
Model: DVDRW GSA-S10N
Firmware: BP08
RPC-2 (region locked)
State is PERMANENT
4 vendor resets left
0 region change left
Region 1

I've looked through :
viewtopic.php?f=30&t=46201
viewtopic.php?f=30&t=45757
viewtopic.php?f=2&t=41228

and the last one which I'm pretty sure has the answer ( but i have no idea how to make it right):
viewtopic.php?f=2&t=46137

I realized if i want to change my DVD to region free, i should have RPC-1 (region free). RPC-2 is locked after 5 changes. Here is my problem: i would like not to have windows and boot camp. So I read that I can change firmware to RPC-1. but I couldn't find link for my system, so with help from a friend I found out I should download Wine, then MCSE tool.
And like in here viewtopic.php?f=30&t=46767 everything worked fine until 12 step. In "applications" it doesn't work. I try to open it, and in half way it stops.
So here I go back to viewtopic.php?f=2&t=46137 , and write in terminal:


but there is the same problem as in flasher:



P.S: I have downloaded flasher, GSA-S10n_BP10.exe , region X ( pretty sure have to use only when DVD will be region free).
and right now just in case nothing works , trying to download boot camp and maybe will follow steps like in here viewtopic.php?f=30&t=45757

But I'm asking your help. Please, if you are not too busy, could you please explain me how can I avoid using boot camp and windows on my computer and get my DVD region free.

Thank you for your time.

you cannot on mac's, unless you use wine, bootcamp. RegionX is not needed, as your drive would be autoreset.

i have Wine, and bootcamp now.
but my problem is that in flasher it always says "bus error". what can i do with that?

In bootcamp you can directly start the .exe file, so you do not need the seperate flasher application. To get the RPC2 autoreset funcitionality, you have to patch the .exe file with my MCSE tool.

also my flasher has not such error of bus type so should read how to use the flasher for the mac.

Since I worked really hard on this and had no idea what I was doing for 5 hours, here is how I did it:
How to do this on a Mac:
Use instructions of MCSE at: viewtopic.php?f=30&t=46767
to create a different drive file (.exe) file.

Download MCSE at viewtopic.php?f=2&t=41228

In the winebottler: http://winebottler.kronenberg.org/
Select (copy only) when you install.

Use your drive found in: http://files.rpc1.org/index.php
(make sure it is the apple drive if your on a Mac)

Inside MCSE:
Hit Load... and browse to the drive downloaded from http://files.rpc1.org/index.php

Then choose what you want... I chose to autoreset RPC2.

Then what you want to do is download the Flasher: http://sourceforge.net/projects/flasher/files/

Next what I did was create a folder in my Applications called App

I then put the .exe file created by MCSE in the folder App and the Flasher in the folder App

Next I opened an application called Terminal.

(Remember that the drive I used was GSA-S10N_AP12... It might be different for you. Substitute the name of your drive for this)

I typed in terminal: cd /Applications/App

Next I ripped the .exe into .bin format by typing: ./flasher -r GSA-S10N_AP12.exe
If it rips correctly you should get (cmd_ripexe: Finished firmware ripping process) (do not type this in)

I then typed in: ./flasher -d Drive ID: 1 -m main_firmware.bin
You should get: cmd_drive: Opening Drive: Drive.

So I am not sure if you need to do the next step.

and then i typed: ./flasher -d Drive ID: 1 -c core_firmware.bin
You should get: cmd_drive: Opening Drive: Drive.

I then dumped cache by typing: ./flasher -d 1 -m main_firmware.bin
You should get cmd_dumpmain: Dump process finished but it might take a little time for the process to complete so wait.

I'm not sure if you need to do the next step.

I then dumped a different cache by typing: ./flasher -d 1 -c core_firmware.bin
You should again get cmd_dumpmain: Dump process finished but it might take a little time for the process to complete so wait.

Now don't quit your application terminal, but check in the folder App which should be in the Applications and there should be two new files called main_firmware.bin and core_firmware.bin (this should still be with the flasher, GSA-S10N_AP12.exe, CORE_GSA-S10N_AP12.exe.bin, MAIN_GSA-S10N_AP12.exe.bin)

Next you want to flash the drive with the new .bin by typing: ./flasher -d 1 -f MAIN_GSA-S10N_AP12.exe.bin
Terminal will then have a space and 3 lines underneath it... you will know it has worked if it does not say error and it says (cmd_flashfirm: Flashing process finished)

Make sure you shut down the machine completely, restarting is most of the times not enough. LG drives need the power to be cut from the drive after flashing it in order to internally re-flash themselves with the new firmware. Once you turn your machine on again your drive should work normally. - cvs said

Please confirm this is right DevilsClaw and cvs...
