Introduction
Payload Dumper pulls partition images, such as boot.img, init_boot.img and vendor_boot.img, out of an Android OTA update, directly on your phone. Most modern OTA packages store every partition inside a single payload.bin. Before you can patch a boot image for KernelSU, APatch or Magisk, you have to get it out of that file. The usual way is a desktop script. This app does the same job without a computer.
What it does
- Opens a
payload.bindirectly, or an OTA zip without unpacking it first. - Lets you choose which partitions to extract, and you can add more while an extraction is running.
- Shows live progress, and you can cancel an extraction partway.
- Verifies the hash of each extracted image, so you know the file is intact before you flash anything.
- Detects incremental OTAs, which it can’t extract yet. You need a full OTA package.
- Has debug logging for troubleshooting.
The extraction engine is written in Rust, which is why the build ships native code for every CPU type.
Updating from an older version
The developer notes that this release needs a fresh installation. If you have an older Payload Dumper installed, uninstall it before installing this version, or the update will fail.
What stands out in the APK
- No trackers.
- All-files access is the one permission that matters. OTA zips are large and usually sit in Downloads, so the app asks for it to read them and write the images out. It is a special permission, so you turn it on yourself in Settings.
- Notifications and a foreground service let an extraction keep running while you do other things.
A typical use
- Download the full OTA zip for the firmware your phone is running now. The build number must match exactly.
- Open it in Payload Dumper and extract
boot(orinit_booton devices that launched with Android 13 or later). - Hand the image to your root manager to patch, then flash the result.
Who should skip it
- You already have a working desktop setup with payload-dumper-go or similar.
- You only have an incremental OTA. Extraction from those isn’t supported yet.
