Setup guide

1. Open the loader page

Connect the phone to the internet and open this JScalated website in the native browser.

Choose Load JScalated or Load JScalated Sideload.

2. Complete the System-page stage

The button stores the loader in window.name and opens system.localhost/proxy.html. On that blank page, type these address-bar commands in order:

javascript:document.createElement('script')javascript:document.write(name)

Do not navigate away between the two commands. The first command is required on affected KaiOS builds before the staged script element will execute.

Troubleshooting

Confirm the phone can open https://jscalated.netlify.app/adb.js.
Check every character in both commands.
If window.name is empty, return to the landing page and press the loader button again.
KaiOS 4 security policy may block individual features even when the loader itself runs.
