Guides

Setup guides that actually match the app

One guide per platform, written against the current build — including the awkward parts most instructions skip, like why macOS asks for your password again after an update.

Windows

Set up ErrorX on Windows

Download the right build, run the installer, sign in through your browser and approve the helper service once. Covers the SmartScreen warning and the UWP loopback fix.

Android

Set up ErrorX on Android

Pick the right APK, accept the system VPN prompt, and — the step most people miss — exempt the app from battery optimisation so it survives the night.

No iOS guide, and here is why

The ErrorX app does not build for iPhone or iPad. If that is your device, use ProxyBD — our sister brand on the same network, with its own app and its own setup instructions.

Understand it first

Before you install anything

Worth ten minutes: knowing how Bangladeshi routing works will tell you whether this product helps you, and stop you being sold something that cannot.

What BDIX bypass actually is

Why your package is fast locally and slow internationally, what a BDIX-side server changes, and what it cannot change.

Common questions, answered

Does it give free internet? Will it raise my package speed? What happens when my plan ends? Straight answers, no marketing.

Testing it properly

How to measure the difference honestly — and why a BDIX speed test tells you nothing about whether ErrorX is working.
