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

1. Install needed dependencies: python -m pip install -r requirements.txt
2. Modify config.yml correctly, as described in the file itself.
3. python probe.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.
