Looks like they changed the appid of GTA 5 Legacy in SteamDB. Try this instead: download_depot 271590 271591 1849782592595337955
 
Edit: Apologies if I had a small typo in my original response, but if the GTAV.exe from that depot doesn't work, you can try this, they're both for GTA V legacy: download_depot 50323840 271591 1849782592595337955

Sorry to hijack this thread, but maybe I can help you with rolling back to 3504.0. This is for the Steam version btw. First make sure to make a backup of the files in your GTA V directory especially GTAV.exe, and make sure to go offline on Steam so you won't get the "verify integrity" error message.
 
Press windows key + run and type in: steam://open/console
 
Then when the steam console appears, type in: download_depot 50323840 271591 1849782595337955
 
This will download the previous version's binaries, but you only need the ver. 3504 GTAV.exe. Once you've made sure you made a backup of the new GTAV.exe and set your status to offline, copy the 3504 GTAV.exe from where steam downloaded the depot files to, and paste them in the directory, replacing the new GTAV.exe. You're then good to go.

I made the mistake of not going offline when I started the game after replacing the new GTAV.exe with the old one and it gave me the "verify integrity" error message, luckily I had saved another 3504 GTAV.exe from when the previous update happened, and it worked. Having a backup never hurts.
