A few days ago my GTA V accidentally updated itself through STEAM and therefore I could not start RPH/LSPDFR! After a bit of searching I could downgrade my installation to the previous version and I want to share how I did that, in case someone else also has this problem:

• Disable automatic updates for GTA V in STEAM (see chapter "Disabling automatic updates" in the steam FAQ)
• Download and extract DepotDownloader
  • Note that you might also need the current .NET runtime to run DepotDownloader
• Run the following commands to download the files that were replaced by the update:

  • DepotDownloader.exe -app 271590 -depot 271591 -manifest 2115862916207197280 -username USERNAME -password PASSWORD
    DepotDownloader.exe -app 271590 -depot 271592 -manifest 928847224211886655 -username USERNAME -password PASSWORD
    DepotDownloader.exe -app 271590 -depot 271593 -manifest 884947165531941009 -username USERNAME -password PASSWORD
    DepotDownloader.exe -app 271590 -depot 271594 -manifest 3839630705452921359 -username USERNAME -password PASSWORD
    

    (replace USERNAME and PASSWORD with your STEAM-account data)

  • This will create folders like "depots\271591\7881101" and download data into it.

  • It takes quite a while to download the 100 GB.

• Move the downloaded data (files and folders except the ".DepotDownloader" folder) from the above mentioned folders into your game folder, overwriting any existing files

• Run the game and RPH/LSPDFR is working again!

 

Of course, make a backup of your game folder prior to overwriting anything, just in case.

 

Some useful links:

1. I roughly followed this guide from a few years ago.
2. the GTA V update history on STEAM-DB

Thanks,  waiting on the last download and going to try this when I get home from work but it appears others have had luck with reverting and being offline, did this work for you? And anyone else reading this, the command in the console is " download_depot (number) (number) " and the file path will be in the console when it's done downloading. The easier way of course is just to backup the game using RH before an update but some of us were too lazy or distracted by putting all the other cool toys in and using them and didn't bother and now we're paying for it.

This did not work for me, and I read it is because the recent steam clients don't allow it any more.

To be sure I started GTA V after the revert while being offline, but lots of my LSPDFR plugins (most notably StopThePed) do not work when they can not phone home (quite a bad habit actually). So I was brave and started again being online, and it worked. Just be sure to disable the updates in the steam-client.

Note that for the current update of GTA V there is already an update of RPH and LSPDFR, so no need to downgrade.

I did what you said but it seems to be crashing on me when I try to load the story mode.

Does it work without LSPDFR (disable LSPDFR-plugin in RPH)? Does it work without RPH?

Nope it does not.

Could it be a savegame you created with the new version?

Oh, yeah it can be. What can I do in that case? I cant load a new game right?

Just checked to start a new game with the old version and it crashed. So I am guessing something else is wrong here.

Good idea, yes, something else is wrong then. I would recommend a fresh install, then downgrade. Maybe that works. But keep in mind, that for LSPDFR you can now use the new version, because LSPDFR and RPH have a proper update as well. Of course, if you need to use ScriptHook V this will not work, because there is no update for that, yet.

Yeah I tried this method out in all ways I can think of, nothing worked for me but yeah I am getting it now and the new version back as well.
