payload-dumper-go

An android OTA payload dumper written in Go.

Download prebuilt binaries for macOS and windows via here.

Features

See how fast payload-dumper-go is: https://imgur.com/a/X6HKJT4. (MacBook Pro 16-inch 2019 i9-9750H, 16G)

Incredibly fast decompression. All decompression progresses are executed in parallel.
Payload checksum verification.
Support original zip package that contains payload.bin.

Cautions

Working on a SSD is highly recommended for performance reasons, a HDD could be a bottle-neck.

Limitations

Incremental OTA(delta) payload is not supported.
