Credits to luk1337 as this is mostly his work while I've adapted to my needs

The dump.sh script extracts and applies incremental OTA updates to a full update package.

1. FullPackage: The name of the full update package, including the file extension (e.g., OP9.zip).
2. (optional) firstpackage: The name of the first incremental update package, including the file extension (e.g., OP9-1.zip).
3. (optional) secondpackage: The name of the second incremental update package, including the file extension (e.g., OP9-2.zip).

Example:

./dump.sh OP9 1 2

This will extract OP9.zip and apply OP9-1.zip OTA to OP9.zip, then apply OP9-2.zip and so on.

Output:

The script will output progress messages as it extracts and applies the updates. Finally, it will prompt the whether to extract the individual blobs from the extracted update.

Example run log

$ ./dump.sh OP9 1
