🧩 Sync for Reddit Fixes

Morphe patches that fix load more comments and Reddit galleries in Sync for Reddit and Sync for Reddit Pro, which broke when Reddit blocked /api/morechildren and /api/info for third-party clients.

These patches are ported from notBrian2/revanced-rif-fixes (written for rif is fun) and adapted to Sync's Volley-based networking code. Use them with the Sync patches from wchill/patcheddit, which handle API access (Spoof client), login and the other fixes Sync needs.

Fix Reddit galleries	Fixes Reddit image galleries failing to load ("Could not load gallery") since Reddit blocked /api/info for third-party clients. Galleries are loaded from /comments instead.
Fix Redgifs API	Fixes "Error connecting to Redgifs": answers the Redgifs endpoints Sync relies on that were removed, uses Redgifs' temporary token, and fixes video ids taken from links like redgifs.com/watch/{id}/?92. Works on Sync and Sync Pro. Turn off Patcheddit's "Fix Redgifs API" when using this one: both change the same code.
Fix load more comments	Fixes "Error loading more comments" since Reddit blocked /api/morechildren for third-party clients. The missing comments are loaded from /comments instead. At the bottom of very large threads Reddit's 500 comment limit can still leave some out.

Using with Patcheddit

Fix Redgifs API replaces Patcheddit's patch of the same name, which fails on Sync because Redgifs removed the /info endpoint Sync calls (Error connecting to Redgifs). Both change the same code, so turn Patcheddit's "Fix Redgifs API" off when you use this one. If both are on, one of them fails to apply.

Supported apps

App	Package	Version
Sync for Reddit	com.laurencedawson.reddit_sync	v23.06.30-13:39 (version code 23033)
Sync for Reddit Pro	com.laurencedawson.reddit_sync.pro	v23.06.30-13:39 (version code 23033)

This is Sync's final release. The free and Pro builds have the same code but different obfuscated names (for example y8/q.b() vs j8/q.c()), so the patches find their targets by the source file names Sync keeps (OAuthGalleryRequest.java, OAuthCommentsMoreRequest.java, CommentsPresenterImpl.java) plus strings and method signatures, never by obfuscated names.

Known limitations

• Very large threads: Reddit returns at most 500 comments per request. Deep in very large threads the last few top-level comments can fall outside that window. Sync then shows Error loading more comments and keeps the "load more" row, instead of spinning or removing it.
• These patches only change where the two requests go. Sync still needs working API access (the patcheddit Spoof client patch with your own client ID), or no request succeeds.

📲 Applying the patches with Morphe

You need your own copy of Sync for Reddit or Sync for Reddit Pro v23.06.30-13:39. This project doesn't provide APKs.

Morphe Manager (on your phone)

1. Add this repository as a patch source: tap Add to Morphe above, or in Morphe Manager add the source https://github.com/trulow/sync-reddit-fixes. (Requires a GitHub release, see Releasing below.) To use a bundle you built yourself, copy patches-<version>.mpp to the phone and add it as a local patch file.
2. Add the patcheddit source as well (https://github.com/wchill/patcheddit) for Spoof client and its other Sync patches.
3. Select your original, unpatched Sync APK, then select the patches you want from this source along with the patcheddit patches you use. If you select Fix Redgifs API here, turn off patcheddit's patch of the same name.
4. Patch and install.

Morphe desktop / CLI

Download morphe-desktop-<version>-all.jar from MorpheApp/morphe-cli releases and run:

java -jar morphe-desktop-all.jar patch -p patches-<version>.mpp -p patcheddit.mpp -o sync-patched.apk sync.apk

To apply only some of the patches, add --exclusive and -e "<patch name>" for each one you want. Use list-patches --patches=patches-<version>.mpp -p -v to see the patches with their supported packages and versions.

🛠️ Building

Requirements:

• JDK 17 or newer. Android Studio's bundled runtime works: export JAVA_HOME="/Applications/Android Studio.app/Contents/jbr/Contents/Home"

• The Android SDK with platform 36 (ANDROID_HOME set, or sdk.dir in local.properties).

• A GitHub token with the read:packages scope, since Morphe publishes its Gradle plugin and patcher to GitHub Packages. Either add gpr.user / gpr.key to ~/.gradle/gradle.properties, or export GITHUB_ACTOR and GITHUB_TOKEN. With the GitHub CLI:

  gh auth refresh -h github.com -s read:packages
  export GITHUB_ACTOR=<your-github-username> GITHUB_TOKEN=$(gh auth token)

Then build:

./gradlew buildAndroid

The bundle is written to patches/build/libs/patches-<version>.mpp. buildAndroid is required: it adds the DEX that Morphe Manager needs on Android.

Project layout

The layout follows patcheddit: one extension module per app under extensions/, and the patches for an app under its own syncforreddit package.

extensions/syncforreddit/                    Extension module, built to extensions/syncforreddit.mpe
  build.gradle.kts
  src/main/java/app/syncfixes/extension/syncforreddit/
    FixLoadMoreCommentsPatch.java            Builds the /comments request, converts its reply
    FixGalleriesPatch.java                   Rewrites the gallery URL, unwraps its reply
    Responses.java                           Shared Volley response helpers
  stub/                                      Compile-only Volley stubs (Sync ships Volley unobfuscated)
patches/src/main/kotlin/app/syncfixes/patches/syncforreddit/
  shared/Constants.kt                        Supported apps, versions, shared names
  fix/comments/Fingerprints.kt               Targets for "load more comments"
  fix/comments/FixLoadMoreCommentsPatch.kt   Bytecode hooks for "load more comments"
  fix/gallery/Fingerprints.kt                Targets for galleries
  fix/gallery/FixGalleriesPatch.kt           Bytecode hooks for galleries

The Kotlin patches only insert calls; the logic lives in the Java extension, which is merged into the app.

How the fixes work

Fix Reddit galleries hooks OAuthGalleryRequest:

1. Its static URL builder returns https://oauth.reddit.com/comments/{id}.json?limit=1 instead of /api/info.json?id=t3_{id}. This URL is also Volley's cache key, which Sync uses to remember the gallery position, so both stay consistent.
2. parseNetworkResponse() first replaces the response with one whose body is the first element of the /comments reply: the same Listing /api/info returned. Sync's parser and its cache handling are unchanged.

Fix load more comments hooks three places:

1. CommentsPresenterImpl's "load more" handler passes the "more" row to the extension, which reads its parent_id (the request itself isn't given the parent).
2. OAuthCommentsMoreRequest's constructor passes the post id, child ids and sort. Right before the super constructor, the api/morechildren POST is replaced by a GET of /comments/{post}.json (top level, depth=2) or /comments/{post}/_/{parent}.json (nested, depth=10), with limit=500, the sort, and a key to the child id list (hundreds of ids would make the URL too long).
3. parseNetworkResponse() turns the comment tree into morechildren's flat {"json":{"data":{"things":[...]}}}: the requested comments and everything under them, in pre-order (parents before replies, which Sync uses for indentation), with "more" items for deeper replies. If nothing could be loaded it returns Reddit's error shape, so Sync shows its normal error and keeps the row.

Fix Redgifs API (adapted from KingOfPoptart/patcheddit, wchill/patcheddit#100) installs an OkHttp interceptor on the client behind Sync's Volley requests. The patch finds that client by following the getter Volley's BasicNetwork calls to the field it returns, so it hooks the same client on Sync and Sync Pro.

1. Sync asks /v2/oauth/client for a token, then /info for its IP address; Redgifs removed both. The interceptor answers both itself, using Redgifs' current temporary token (/v2/auth/temporary), cached per user agent.
2. /v2/gifs/{id} goes out with that token and Sync's own user agent. If Redgifs rejects it (tokens are tied to the IP address that requested them, so switching networks invalidates one), the request is retried once with a new token.
3. LinkHandler.getGfycatId strips the query before the trailing slash, so links like redgifs.com/watch/{id}/?92 no longer give an empty id.

🚀 Releasing
