Hello, I do not have any idea what goes on behind the scenes in the python file, but the result doesn't seem to work for me.

I'm trying to extract a payload.bin from a Nokia 7 OTA file (~150MB). The phone does use A/B.

The command stars and then stops with just 2 files in the output directory. These are:

  1. cda.img
  2. splash.img

Here's the output from my terminal.

Hi,

This looks similar to issue #1 . Operation type 4 is SOURCE_COPY and type 5 is SOURCE_BSDIFF, I suppose this is an incremental firmware upgrade. I should update the README to mention the tool can only be used with full firmware upgrades.

Added note to README (df621cb0945ee987bcf74ed0fa57b3e3d3ef0a9e)

Well, the part "OTA" in the name and description gave the idea that it also handles partial packages as well. When do OEMs provide full packages as OTA? Pretty rare, isn't it? Still, thank you for the quick response.
