Disclaimer: you must own a legal PC copy of the game to use this patch, it does not contain any original game file and is thus useless without them.

How the patches work

The patches do not contain the entire old files, instead they contain only data about the differences between the old and new files versions. This data is used to transform the newer files back into their old version.
The advantages of this method are a considerably reduced file size and a smaller risk of DMCA takedown.

Fallout 4 Update 1.9 Codex Download

The Fallout 4 1.9 update is now available for Xbox One, PlayStation 4 and PC and it’s a big one. Today we want to take a look at everything you need to know about the Fallout 4 1.9 patch and its. Hi Patch 1.3 Fallout 4 transformed game from playable to unplayable on my PC. Thanks to Dalen and all for the rollback patch directions and link for 1.3.47 to 1.2.37 which restored game playability.

Instructions

How to use

1. Extract all files to Fallout 4's directory (where Fallout4.exe is located)
2. Run patch.bat and follow its instructions (do not close while patching!!)
3. If you don't play the English version, install string files: click here
4. (optional) Keep a copy of the folder in case Steam updates your game. If you don't do this you will have to wait for a new downgrade patch when a new Fallout 4 update is released.

Notes
-If the .bat seems blocked, right click anywhere inside the window. For some reason selecting text pauses the script on Windows 10, right click to deselect.
-You might need to launch patch.bat as admin if the game is in Program Files.
-You can delete the files you extracted and the .bak files after patching successfully.
-If you closed the window while it was patching and now have corrupted files, you can restore them by renaming the .bak files. Verifying the game cache in Steam is also an option.
-If you want to update to the latest version just verify the game cache in Steam.

Compatibility

-DLCs won't work with versions older than them and are not downgraded along the main game, this might cause unexpected side effects.
-Only the English version is fully supported
