Google OTA prober

This program is designed to obtain URLs to over-the-air (OTA) update packages from Google's servers for a specified device.

Requirements

• Python 3
• Build fingerprint of your stock ROM

How to use

You must install dependencies before using the tool: python -m pip install -r requirements.txt

Option 1: Using a terminal

There are three ways to get the URL, which are listed here:

python probe.py --fingerprint <fingerprint>   # Skips reading config.yml entirely.
python probe.py --config <filename>           # Reads a custom YML file (same format as config.yml)
python probe.py                               # Reads config.yml

If you wish to download the OTA file, pass --download as an argument on your terminal.

Option 2: Using a graphical interface

This option requires installing all needed modules in requirements-gui.txt. You must have the fingerprint for your device. The model code is optional, but encouraged.

You can run the GUI with python gui.py.

Limitations

• This only works for devices that use Google's OTA update servers.
• The prober can only get the latest OTA update package that works on the build specified in config.yml.
• Unless it is a major Android upgrade (11 -> 12), the prober will only get links for incremental OTA packages.
