Unpatching 1.4.3 back to 1.4.2 without reinstalling
It is highly recommended you backup your patched client first as this involves editing an MPQ to remove the new patch. Standard disclaimers apply!

Basically the idea here is to break your Starcraft II client by deleting files corresponding to the new patch and then using the Repair Tool on the SEA patch server to fix it back up.

Step 1. Delete the new patch
Open your StarCraft II\Versions folder and delete the Base21029 folder.

Step 2. Delete the backup of the new patch
You will need for this step a MPQ editor. I used the following one which is nice and simple - just extract and run.
http://sfsrealm.hopto.org/cgi-bin/do...WinMPQ_VB6.zip

Source: http://sfsrealm.hopto.org/downloads/WinMPQ.html
If it doesn't work, you might need the various runtimes from this page (VB6, VB4, Runtime Pack 3).

Open the StarCraft II\Mods\Core.SC2Mod\Backup.MPQ file in your MPQ editor and delete the files corresponding to Base21029.

Step 3. Repair the repair tool
Now, the repair tool has a bug where it always connects to the NA patch server regardless of the selected region. To workaround this, you will need to edit your hosts file to redirect it the SEA patch server.

1. Open the C:\Windows\System32\drivers\etc\hosts file in Notepad.
2. Add the following line to the end of the file and save it.

202.9.66.78	enUS.patch.battle.net

Step 4. Run the repair tool
Now you can run the Repair tool found in StarCraft II\Support\Repair.exe. The progress will be uneven, there will be periods where it will zip through (these are the unchanged files) and bits where it will take a while (downloading old files to fix the install).

Step 5. Make sure you are on SEA!
Once the Repair Tool is done, make sure you have SEA selected as the last region. The easiest way to do this is to hit Windows+R to bring up the Run window and run the following command (just copy and paste).

reg add "HKCU\Software\Blizzard Entertainment\Battle.net\S2" /v "LastPortal-enSG" /t REG_SZ /d sg /f

Step 6. We're done!
Finally, just to clean up, remove the line you added to your hosts file earlier on.

You should now be able to run StarCraft II 1.4.2 and play on SEA!

When you first start the repair, you should see something like this:

In particular, note if the Locales and Version match.

• If the locale is wrong, make sure you are in fact trying to repair a SEA copy that hasn't been messed with to be Korean localized or similar.
• If the version is wrong, check the files were actually deleted from the MPQ (if you have UAC enabled, it may be not writing to the Program Files directory).
• If they do match, check the hosts file in step 3 took effect by pinging enUS.patch.battle.net. If it resolves to an IP other than 202.9.66.78, it is repairing from the wrong server and won't work. Again, may need to Run As Admin if UAC is enabled.

The locale and version were correct, I changed the hosts file again and now it's working!

Thanks paperclip

alternatively if you have logged into NA and downloaded the patch then log back into SEA (will fail) and reinstall starcraft as well as download the 22 patches. easier but probably takes longer.

yes i was stupid enough to download the na patch.

Mine doesn't work I've done everything and the details on the Repair tool matches yours. When I ping enUS.patch.battle.net I get "pinging us.patch.battle.net (12.129.206.133)"

That means you haven't done the step 3 properly, the IP should be 202.9.66.78. Make sure you pasted the line as it is (no # or anything like that).

Ah sorry. I did a rookie mistake. Totally forgot to remove the file extension lol

[IcedTea]

You fixed my SC2. Thank you, so so much. You truly are a miracle worker. xD

Thanks for the post! Does anyone have any idea when the patch comes out for SEA? Or if it's an auto-fix for when it comes out?
