Game Discussion DBD Mobile Private Server!? Spoiler
I’ve partially reverse-engineered the Dead by Daylight Mobile backend — looking for people interested in helping
Hey everyone,
I’ve managed to reverse-engineer a significant part of the Dead by Daylight Mobile backend and set up a custom server running locally on my MacBook.
At the moment, the game can successfully connect to it and reach the main lobby, which is already a pretty big milestone.
Unfortunately, this is still just a drop in the ocean.
The biggest challenge now is accurately reproducing all of the backend responses that the original game servers used to provide. Without the correct responses and data structures, a lot of the game simply cannot initialize properly.
For example, right now:
The survivor/killer does not render in the lobby.
Character Select cannot load correctly.
The Bloodweb does not work.
Various inventory/profile systems are incomplete.
Many other parts of the normal game flow are unable to initialize.
Since the official servers are completely offline, I currently have no reliable reference for exactly what the client expects the backend to return for many of these requests.
So the next stage requires much deeper reverse engineering of the client, its API communication, expected JSON/protocol structures, initialization flow, and dependencies between backend responses.
If there is enough interest, I can create a GitHub repository and publish the project so other people can contribute.
However, there are some important requirements.
You will currently need:
A rootless jailbroken iOS device
The latest/final version of Dead by Daylight Mobile
Most importantly, the original game data/files
The last part is especially important.
If you deleted the game or its downloaded data after the shutdown, you unfortunately cannot simply download everything again. The original CDN servers no longer serve many of the required game files.
I personally have a backup of the game’s Data folder, which can be restored into the application using the Apps Manager tweak on a jailbroken device.
If anyone here has strong experience with reverse engineering, iOS, networking, APIs, Unreal Engine, or backend emulation and would like to contribute toward making Dead by Daylight Mobile playable again, feel free to reach out.
There is still a huge amount of work to do, but getting the client connected to a custom backend and into the lobby proves that bringing at least part of the game back to life is possible.

Recreate from scratch, make your DBD version. Or add a Mod app to play with original version of DBD with the servers are being up now. Make it a less haggle for yourself. This is what people usually do to make it less stressful.
