ReVanced Patch Failed Fix

A ReVanced patch failed error is the first wall most new users hit, and the cause is nearly always the same. Patches do not edit an app by description, they locate exact points inside its compiled code and rewrite them. When you feed the patcher a base app that is newer or older than the one those patches were written against, the code they are looking for is not where they expect, the lookup fails, and the run stops rather than producing a half modified app.

ReVanced patch failed: fix steps

Use the exact base version Manager names, not the nearest one you can find. The patch screen shows a supported version for each app. A build one release away fails as reliably as one a year away.
Update ReVanced Manager before anything else. Manager and the patch bundle move together, and an old Manager running a current bundle produces failures that look like patch problems but are not.
Clear Manager's storage and let it download the bundle again. A partially downloaded bundle throws errors that change every run, which is the tell for corrupt cached data rather than a real incompatibility.
Check that your base APK is a full package rather than a set of split APKs. Anything pulled from a Play Store install is split by default, and the patcher cannot work with the pieces.
Free up storage before starting. Manager keeps the base APK, its intermediate files and the finished build at the same time, so budget several times the size of the app.
Run the default patch selection on your first attempt. Adding optional patches is how you find out which one is broken, and doing that before you have a working baseline wastes an hour.
Read the last lines of the log when it stops. The failing patch is named there. If the same patch fails every time, deselect it and build without it.

Why a ReVanced patch fails

Base version mismatch. This is the majority of reports and the reason the recommended version exists at all.
The wrong kind of APK. Split packages, region specific builds and repackaged files from mirror sites all fail for the same reason: the code inside is not the code the patches were written for.
Memory or storage running out mid run. This produces an abrupt stop rather than a named patch error, so a run that dies with nothing useful in the log is usually this.
One optional patch that is broken in the current bundle. Everything else applies, one fails, and the run stops there.

If none of this worked

Patch on a computer with ReVanced CLI. It runs the same patcher with far more headroom and prints an error you can act on. The PC guide covers the setup.
Try the previous patch bundle if Manager lets you select one. A bundle released hours ago can carry a regression, and the version before it may build cleanly.
If Manager crashes rather than reporting a failure, that is a different problem. The Manager crashing guide is the right place.
Sometimes the honest answer is to wait. When YouTube ships a change that breaks a patch, no amount of retrying fixes it, and the patch gets updated on its own schedule. Building nothing for a few days is a normal part of using this.

Questions people ask

Where do I get the exact base version? Manager can download it for you on most setups. If you source the APK yourself, match the version string and the architecture exactly.
Can I patch a newer YouTube than the recommended one? You can try, and it usually fails. When it does succeed, expect parts of the app to misbehave in ways that are harder to diagnose than a clean failure.
Does patching need root? No. The non-root path is the normal one, and root changes installation rather than patching.
Is a failed patch dangerous? No. A failed run produces no installable file and leaves your installed apps untouched.

If patching still fails after all of this, save the log from Manager before asking anywhere for help, and say which base version, Manager build and patch bundle you used. Those three facts answer most questions before anyone has to ask them, and without them a report is unanswerable.

For a clean run from the beginning, the Manager guide covers setup and the patches page explains what each patch actually changes, which makes it easier to build without the optional ones you do not need.

Extra notes before you retry

If the problem comes back after a fix, note your YouTube base version, your ReVanced Manager build, and whether GmsCore is installed before trying anything else. A version mismatch between those is behind most repeat failures.
