If you ever need to fix a broken system app, such as a broken browser, here's how you can do so.

What you need:

• JNUSTool
• Java
• WUP Installer GX2 mod or UDPIH

1. Find the title ID for the app you want to fix from WiiUBrew (EUR browser would be 000500301001220A)
2. Extract JNUSTool to a folder and run `java -jar JNUSTool.jar [titleid] -dlEncrypted`
3. If you get Invalid title ID, remove the - from the title ID
4. Once the download finishes, copy temp_[titleid] to install on the root of your sd card.
5. Open WUP Installer GX2 mod (tiramisu only) from the HBL, or launch UDPIH
6. Install the app you need to fix, and you should be good.
