Tutorial How to create unsigned APK file for rooted devices + Lucky Patcher/Core Patch

Hello,

Is it still true that there is no straightforward way to unsign an already signed APK using newer signing schemes? When I built the final modded apk using objection (modded via Frida and frida-il2cpp-bridge), it automatically signed the file. Is there an additional parameter that you can pass to objection to prevent signing? I haven't been able to find a method just yet...

You can just copy original META-INF to the signed APK so it will become unsigned. I don't know much about Frida, maybe ask for author if there is a parameter to prevent signing

Unfortunately, the installation of the package can not proceed due to the following error after moving the META-INF folder from the original APK to the modded version:

The devices I tried running it on are both on Android 13, but one is rooted (has CorePatch and TrustMeAlready) and the other is not.

You might want to enable Lucky Patcher on Xposed too. Sometimes unsigned APK works along with Lucky Patcher and Core Patch together. See the tutorial for Lucky Patcher: How to install unsigned APK using Lucky Patcher (Xposed method) - Platinmods.com - Android & iOS MODs, Mobile Games & Apps
If it does not help, please file an issue Issues · LSPosed/CorePatch
 
My apk using v1 v2 and v3, how can I create unisgned apk? I tried the method above but it's not working. It installs, but the game detects.

Unsigned APK does not bypass any game security. You need to find another method for that (Don't ask me)

Objection has added an option to skip signing via the --skip-signing flag – PR Completed, so any signing issues have likely been fixed.
 
Hi @AndnixSH, I've tried all your methods using CSR Racing 2 MOD Menu APK by @GNaFF, and it's not working. I'm using LDPlayer 9 fully rooted and patched (Corepatch+LP).

The first method you mentioned is to Copying original META-INF to modded APK. I've done that using original APK downloaded from APKCombo and it's not working, I still can't use Google to login.

After that, I tried to use the basic method where you need to download the game from Play Store and login using Google then install the MOD APK over the original APK but still did not work (There is a pop-up of Google Play Games but it just stuck on loading screen like 20-30 mins and I tried to re-open the game and the Google Play Games pop-up not showing but I can play the game with the local save without Google login).

The second method you mentioned is to try copy entire contents from signed APK to original APK except META-INF and still not working.

The last method I used is by combining your method and the basic method I've mentioned before to install the MOD APK but still not working.

Do you have any other solutions?

Thank you and sorry for my bad English. Peace!

Note: I've done this many times using different signed APKs and mostly works either using your method or the basic method but this one I don't know why it's not working.
