Post-Installation: Fixes & Tweaks

After installing your Nokia G300 custom ROM, you will likely face two major issues:

1. The Camera Dies The stock camera app relies on Nokia’s proprietary HAL (Hardware Abstraction Layer). On custom ROMs, install GCam (Google Camera) for Snapdragon 480. Look for a config file specifically for the "Nokia G300" on CelsoAzevedo’s site.

2. Wi-Fi Calling / VoLTE Vanishes Custom ROMs rarely include carrier IMS settings for T-Mobile (the G300’s primary carrier in the US). To fix this, you need to manually push your carrier’s mbn file via the Engineering Menu (*#*#3646633#*#*), which requires root. This is advanced.

Step 3: Wipe the System

• In TWRP, go to Wipe > Advanced Wipe.
• Select: Dalvik / ART Cache, System, Data, Cache.
• Do not wipe Internal Storage if your ROM is saved there.

7. Iterate and Share

• Debugging: If you encounter issues, debug your ROM, make adjustments, and rebuild as necessary.
• Share: Consider sharing your custom ROM with the community. Platforms like XDA Developers are great for sharing and getting feedback.
