@miri2121 That error is the default error when you try to install the game you downloaded without doing any backport. So something you’re doing is wrong. The app is modifing the files for sure. So I guess you think you install that modification package and it is saved in the system even if you try to add any update later.

Try to explain here what steps are you doing and I mean what is what you’re installing in the PS4 and in which order.

Explain in detail. What games? How're you building the pkg. And how are you installing them? Show me the steps you're doing. That error means you're not using a backport.

@RetroGamer74 same error happened to me with Phoenix Wright trilogy (both base game patch and update patch) and Disney's classic collection.

the steps are the same i did for the games that worked: build the base game patch, build the patched update (if available), install the game and its patch and test, then install the patched update (if available).

so far it was working with many games (shenmue/divinity 2) but now it isn't working (the patches build with no error code or anything, but even after installing them i get the error). I have noticed that both were released originally late in 2019 on 6.72, which means their *** is high, so maybe that is the issue?

The right procedure when you got a game update is.
  1. Install base game.
  2. In AutoBackPort set Base Game PKG, set Update PKG, set Destination Folder. Build Fuill backported update PKG.
  3. Install backported PKG.
When you don't have game update of the base game then, the procedure is
  1. In AutoBackPort, set Base Game, set Destination folder.
  2. Build backported fixed pkg for base game. (It's in fact a pkg that works as an update)
  3. Install dumped base game
  4. Install the new backported fixed update.
This is the right path.

Also be sure there is no A/V blocking the different tools ABP needs to call. Some ppl reports as false positive any tool in the bin folder. This tools are the FakePKG tools which is something very well known in the scene.

We're going to do a release removing all files not need it.



Hi mate
I downloaded and installed the base game of Crash Team Racing Nitro Fueled duplex and after I installed the fix 5.05 for game that i did with AutoBackPort 1.04 but it didnt work , but one I downloaded worked so I dont understand whats wrong with AutoBackPort 1.04.

Maybe is something wrong with version of AutoBackPort 1.04?

Thank you for your time.

@RetroGamer74 so i downloaded V1.05, put it and its needed folders on the desktop (they were originally in a sub menu of a folder in the "downloads" section), renamed the folders and the games and the updates to 1 letter each, and tried again. this time both games worked. so, it seems like one of the variants between this try and the last one (version number/location/name of folders and PKGs) was the reason for last time not working and this time working. no idea which one it was, just wanted to report the results to you. :)

@miri2121 New guess for people with the CE-40740-5. As I said before if you receive this message the downgrade procedure didn't work. Maybe, A/V have removed or blocked two files that should be located in the bin folder of APB. downgrade_elf.exe and downgrade_sfo.exe. Check if those files exists.

If not exists then probably your A/V removed or quarantined them.

If they exists try to run them opening a CMD window. If you run downgrade_elf.exe for example you should see an answer like this:
usage: downgrade_elf.exe [-h] [--verbose] ...... and so on.
Let me know.

@unbreakable It would be very helpful if you could isolate the issue step by step. Instead to change many things at a time, just one by one. For example, could you put the app, in the same folders you installed before and try again. If that works, could you use the destination folder like before. And finally if everything works, renaming the PKG as the original name.

That will help us a lot, to fix the issue.

AutoBackPort 1.06
Issue CE-40740-5 fixed. (I hope) :)
This issue happened when decrypting files if destination folder contained blank spaces.
Let's see if this is the fix for some of you reporting this error.
Thanks everybody for the feedbacks.
They're really useful.

I added to the ABP base game file and a update. The error you see in the attached scren and the error message code appeared.

@RetroGamer74 I did the experiements one by one as you mentioned with v1.06 and Yooka Layle 2, and an interesting result happened: with the original setup only the game+base game fix worked. adding the fixed update led to the CE-40740 error again.

so I experimented a couple of times and the change that allowed me to make a working update was moving the autobp folder from the location it was in to the desktop. its original location was "C:\Users\username\Downloads\Ant Vids\PS3&4\autobp".

Maybe the long address+the long name of the update PKG somehow led to a problem? not sure, but at least now we know what triggers the issue. :)
