OTA-unpacker

A tool for unpacking Android OTA update files (Both full and incremental updates ).

Usage

To see usage just run :

./unpacker.py -h

If it is a full update, then run:

./unpacker.py ota_update.zip

In case of an incremental update, then run:

./unpacker.py -i -o ota_update.zip incremental_ota_update.zip

Instead of giving there zip's you can also give their corresponding payload.bin as the argument.

Here is how the output is during extraction
