- KonstaKANG Resize Tool
Installation Process
1. Image Preparation
Download the latest Android TV image from KonstaKANG's repository:
Use Raspberry Pi Imager or BalenaEtcher to write the ZIP file directly to your microSD card. The 2024 builds support direct flashing without manual extraction.
### 2. First Boot Configuration
Insert the SD card and connect peripherals:
1. Press `F1` during initial remote pairing screen
2. Configure Wi-Fi/Ethernet under Settings > Network
3. Enable Developer Options (Settings > About > Build number 7x taps)
4. Activate Advanced Reboot (Settings > System > Buttons)
### 3. Google Services Integration
1. Reboot into TWRP Recovery (Advanced Restart > Recovery)
2. Mount USB drive containing:
- MindTheGapps-TV-arm64-13.0.zip
- Widevine-L3-AndroidTV.zip
3. Flash packages in this order:
- GApps
- Widevine
4. Factory reset via TWRP > Wipe
5. Reboot system
### 4. Google Device Registration
After initial setup:
1. Install Terminal app from Play Store
2. Run:
- Visit Google's device registration portal with the output
- Reboot to activate certified status
5. Storage Optimization
KonstaKANG's resize tool maximizes SD card space:
- Download
KonstaKANG-rpi-resize.zip - Boot into TWRP and flash the package
- Automatic partition resize completes in 2-3 minutes
Advanced Configuration
Performance Tweaks
- GPU Memory: Set to 1GB in
/boot/config.txt - ZRAM Swap: Enable 2GB compressed swap
- Thermal Management: Add heatsink + 40mm fan
Input Methods
| Control Method | Setup Guide | |-------------------------|--------------------------------------| | CEC (TV Remote) | Enable in Settings > HDMI-CEC | | IR Remote | Configure with LIRC + FLIRC case | | Mobile App | Use Android TV Remote app | | Game Controller | PS/Xbox controllers via Bluetooth |
Key Features Achieved

- Chromecast Built-in: Via third-party apps like AirScreen
- Dolby Audio: Pass-through to AV receivers
- Automated Updates: OTA updates through TWRP
Challenges & Solutions
HDMI-CEC Compatibility
Older TVs required manual EDID injection using tvservice commands to enable proper aspect ratio and audio formats.
DRM Limitations Netflix/HBO Max initially showed HDCP errors until implementing proper device registration and Widevine L3 installation.
Thermal Throttling Adding a $5 heatsink fan combo maintained sustained performance during 4K streaming sessions.
Usage Statistics
After 3 months of daily use:
- 98% app compatibility rate
- 2.1s average app launch time
- 18W peak power draw
- 55°C max operating temperature
Conclusion
This Raspberry Pi 5 Android TV setup rivals commercial devices like Nvidia Shield TV Pro, offering:
- Full Linux subsystem access
- Custom ROM modifications
- Hardware expansion capabilities
- Cost savings of 60-70%
Future plans include integrating AI upscaling via TensorFlow Lite and adding ATSC 3.0 tuner support through USB attachments. For technical users wanting complete control over their media center, this remains the ultimate Android TV solution.
