Check Your Current LMC Version

First, verify which version you are using.

How to check

  1. Open LMC 8.4
  2. Go to Settings
  3. Scroll to About
  4. Note the version (for example: R17, R18, etc.)

This helps you decide whether an update is necessary.

Before Updating (Important Checklist)

✅ Backup your XML configs

Updating may reset your settings.

Backup method:

  • Go to:
    Internal Storage > LMC8.4 > Configs
  • Copy XML files to a safe folder

✅ Note your current working settings

If you customized manually:

  • Screenshot key settings
  • Save your working XML
  • Remember your interface model

✅ Ensure enough storage

Keep at least 300–500 MB free space before updating.

Safe Method 1: Update Without Uninstalling (Recommended)

This is the easiest and safest method.

Step 1: Download Latest LMC 8.4 APK

Download the newest stable build from a trusted source like lmc84.io.

Important checks

Most LMC builds support direct update.

If everything works smoothly, the update is successful.

Safe Method 2: Clean Install (When Problems Occur)

Use this only if the normal update fails.

When to use clean install

  • App keeps crashing
  • Update fails
  • Major version jump
  • Severe bugs in old build

Step-by-step clean install

Step 1: Backup configs

Copy XML files from:

Internal Storage > LMC8.4 > Configs

Step 2: Uninstall old version

  • Long-press app
  • Tap Uninstall

Step 3: Install latest APK

  • Open new APK
  • Tap Install
  • Launch the app

Step 4: Restore your XML

  • Move XML back to Configs folder

Your optimized settings will return.

How Often Should You Update?

There is no need to update every time a build appears.

Good update timing

✅ When a stable version is released
✅ When your current build has bugs
✅ When your device gains support improvements
✅ Every few months for best performance

Avoid updating to every experimental release unless you enjoy testing.
