How to Fix Error 12 in Pokémon GO (Location Spoofing Guide)

How to Fix Error 12 in Pokémon GO (Location Spoofing Guide)

If you’re using a rooted Android device for Pokémon GO location spoofing, you’ve probably encountered:

Error 12: “Failed to Detect Location.”

It’s one of the most common issues—but also one of the easiest to fix once you know what’s causing it.

At SatComShop, we’ve worked with thousands of devices, and the #1 cause of Error 12 we see is:

👉 Letting the phone battery die while the device is still powered on

This can interrupt critical services like Magisk, Zygisk, and LSPosed, causing your spoofing setup to break—even if everything looks normal.

Why Error 12 Happens

Error 12 appears when Pokémon GO can’t properly verify your device’s location. In most spoofing setups, that means something didn’t load correctly in the background.

Common causes include:

  • Zygisk not initializing
  • DenyList not applying correctly
  • LSPosed modules failing to load
  • System interruption (like a dead battery)

Step-by-Step Fix for Error 12

Follow these steps carefully:

1. Check Zygisk in Magisk

  • Open the Magisk app
  • Tap the gear icon (Settings)
  • Find “Enable Zygisk”

Then:

  • If it’s OFF → turn it ON
  • If it’s already ON → toggle it OFF, wait 5 seconds, then turn it back ON

⚠️ Do NOT reboot yet

2. Verify DenyList Settings

  • In Magisk settings, tap “Configure DenyList”
  • Make sure Pokémon GO is checked
  • Expand it and ensure both toggles are enabled

3. Check Magisk Modules

  • Go to the Modules tab

Confirm:

  • All modules are enabled

If any are OFF:

  • Enable them
  • Then reboot the phone

4. Verify LSPosed Settings

  • Open LSPosed
  • Go to Modules → Hide Mock Location

Make sure:

  • System Framework ✔
  • Pokémon GO ✔

Then:

  • Reboot the phone again

5. Start Spoofing

  • Open GPS Joystick
  • Set location → tap Start
  • Open Pokémon GO and log in

✅ Error 12 should now be fixed

  • 🔄 Restart occasionally
