Can't login (rootless patched Snapchat signature problems)

[KuVa187]

Description

After debloating my S22, I encountered a problem where Snapchat (and Twitter), both of which were patched, wouldn't open. I received an error message stating, "The app contains an error... blah blah." I figured out that the issue was related to LSPatch v0.6, the latest stable release version. I then tried ONPatch v0.0.7-alpha.2 from a Chinese Telegram channel (NPatch) and an LSPatch debug build from an LSPatch fork by JingMatrix (lspatch-debug-8fb330f), both of which fixed that problem.

The current issue, however, is that I can't log in, receiving the following error message: "Due to multiple sign-in attempts or suspicious activity, your access to Snapchat has been temporarily disabled." I tested various Snapchat versions, ranging from 12.63.0.55 to 13.12.0.37 (though not every single version in between), but all of them displayed the same error. I also tried the latest SnapEnhance debug build 7458d57 to see if that would resolve the issue, but it didn’t.

To ensure the problem wasn't with the APKs I got from APKMirror, I installed Snapchat without patching, and the login worked perfectly fine. I also tried local patching instead of embedded patching, but that didn’t work either. When I attempted this, it said the signatures didn’t match, so I had to uninstall the "normal" unpatched version of Snapchat to install the locally patched one. I think this might be a clue as to what’s causing the issue, but I’m not sure how to fix it. Does anyone have any ideas on how to get the signature right?

Reproduction steps

1. Do some stupid debloating to irreversibly break something in OneUI 6.1 (Android 14)
2. Install a debug build of LSPatch
3. Download any Snapchat Apk from Apkmirror
4. Download any version of SnapEnhance
5. Patch the two together (embedded method) using LSPatch
6. Install both the patched Snapchat and SnapEnhance
7. Restart your device
8. Open Snapchat and go through the SnapEnhance "setup"
9. Type in your email and password
10. Get error message

Logs

If you want to see logs of whatever, write me but I've checked them myself and didn't see any error both in SnapEnhance and in LSPatch.

Open shizuku
Click on snapchat and optimize app

Also wait for Snapenhance and snapchat to load like for 2-3 seconds and then try

I already tried optimizing it and updating the loader (in LSPatch and not Shizuku). Then I restarted my device but it still didn't work. Just for the sake of trying I tried it again but nothing changed. Still the error "Due to ... blah blah ... suspicious blah ... access temporarily disabled".

Use these builds and try

[KuVa187]

I tried them (for LSPatch both the release and debug version) but it still doesn't let me login. Probably unrelated but this debug version of SnapEnhance gives me an error when generating mappings "Method setCurrentState must be called on the main thread". This was not the case with the previous debug build (https://github.com/rhunk/SnapEnhance/actions/runs/11255829643).

That error is normal
Open Snapenhance and regenerate mapping

[KuVa187]

yeah but that still doesn't fix my issue

#637

[KuVa187]

I don't want to lean myself too far out the window but i don't think the people in issue 637 have the same problem as me. Ofc i didn't try everything suggested in that issue yet but force stopping the app (which worked for the other guy) didn't work for me. Oh and I have a question, do i need to tick the "overwrite version code" option in LSPatch or not? Because up until now i always did.

Nah dont use override code until or unless u frequently downgrade or update snapchat
