Fetch metadata for your firmwareCode

Create python virtual environment, install requests module with pip:

~/ python3 -m vev .venv
~/ source .venv/bin/activvate
~/ pip install requests

Now you'll be able to run the script:

~/ python firmwareFetch.py
Usage: python script.py <firmware_code>

The script will create downloaded folder and place .md docs under it for each *grih.gree.com server. Here is an example:

~/ python firmwareFetch.py 362001065279

When you're done, deactivate your python virtual environment.

~/ deactivate

How theese firmwares were got

From an old version of Android mobile application hardcoded firmwareCode were extracted.

Using theese codes you can continue to http://{GREE_SERVER}/wifiModule/Lastversion?firmwareCode= and get a firmware download link.

There can be different updates for different regions. Known servers:

grih.gree.com
tmp.grih.gree.com
test.grih.gree.com
kfgrih.gree.com
ru.grih.gree.com
na.grih.gree.com
hk.grih.gree.com
eu.grih.gree.com
in.grih.gree.com
sa.grih.gree.com

Example

~/ curl 'https://grih.gree.com/wifiModule/Lastversion?firmwareCode=36300000257' 2>/dev/null | jq
