+# Phase 1 Implementation: Hardware Access & Bootloader Research
+
+## Current Status
+Based on our research, we have comprehensive hardware specifications and bootloader analysis. Now we need to implement practical testing and development.
+
+## Implementation Plan
+
+### 1. Development Environment Setup
+
+#### Required Tools
+- **Cross-compilation toolchain** for ARMv7
+- **QEMU** for ARM emulation
+- **Buildroot** for minimal rootfs
+- **Linux kernel source** (mainline + CAF patches)
+- **Device tree compiler** (dtc)
+- **Fastboot/ADB tools**
+
+#### Setup Commands
+```bash
+# Install cross-compilation tools
+sudo apt install gcc-arm-linux-gnueabihf g++-arm-linux-gnueabihf
+
+# Install QEMU for ARM
+sudo apt install qemu-system-arm
+
+# Install device tree compiler
+sudo apt install device-tree-compiler
+
+# Install Android tools
+sudo apt install android-tools-fastboot android-tools-adb
+```
+
+### 2. Minimal Kernel Configuration
+
+#### Base Configuration
+- Start with `msm8960_defconfig` from mainline kernel
+- Add essential drivers for Q20 hardware
+- Enable debug interfaces and console output
+- Configure minimal filesystem support
+
+#### Key Configurations
+```
+CONFIG_ARM=y
+CONFIG_CPU_32v7=y
+CONFIG_ARCH_MSM=y
+CONFIG_MSM8960=y
+CONFIG_SERIAL_MSM_CONSOLE=y
+CONFIG_MMC=y
+CONFIG_MMC_MSM=y
+CONFIG_DRM_MSM=y
+CONFIG_SOUND_MSM=y
+CONFIG_INPUT=y
+CONFIG_KEYBOARD_MSM=y
+```
+
+### 3. Device Tree Development
+
+#### Base Device Tree
+- Create `q20.dts` based on MSM8960 reference
+- Define memory map and CPU configuration
+- Add essential peripherals (UART, MMC, GPIO)
+- Configure display and input devices
+
+#### Key Device Tree Nodes
+```dts
+/ {
+    model = "BlackBerry Classic Q20";
+    compatible = "blackberry,q20", "qcom,msm8960";
+    
+    memory {
+        device_type = "memory";
+        reg = <0x0 0x80000000>;
+    };
+    
+    chosen {
+        stdout-path = "serial0:115200n8";
+    };
+};
+```
+
+### 4. Minimal Root Filesystem
+
+#### BusyBox-based Rootfs
+- Use Buildroot to create minimal rootfs
+- Include essential tools (sh, ls, mount, etc.)
+- Add network tools for debugging
+- Configure basic init system
+
+#### Essential Packages
+```
+busybox
+dropbear (SSH server)
+iw (Wi-Fi tools)
+alsa-utils (audio)
+```
+
+### 5. Boot Image Creation
+
+#### Android Boot Image Format
+- Create `zImage` from kernel
+- Build minimal `initramfs`
+- Package as Android boot image
+- Test with QEMU first
+
+#### Boot Image Structure
+```
+boot.img:
+├── kernel (zImage)
+├── ramdisk (initramfs)
+├── device tree (q20.dtb)
+└── second stage (optional)
+```
+
+### 6. Testing Strategy
+
+#### QEMU Testing
+- Test kernel boot in QEMU
+- Verify device tree loading
+- Test basic hardware emulation
+- Debug boot issues
+
+#### Hardware Testing (when available)
+- Test on actual Q20 device
+- Verify debug interface access
+- Test bootloader interaction
+- Document hardware behavior
+
+### 7. Debug Interface Setup
+
+#### Serial Console
+- Configure UART for console output
+- Set up USB-to-serial communication
+- Enable kernel console messages
+- Test debug output
+
+#### Network Debug
+- Configure network interface
+- Set up SSH access
+- Enable remote debugging
+- Test network connectivity
+

+4. Test kernel compilation
+
+### Step 3: Device Tree
+1. Create base device tree
+2. Add hardware definitions
+3. Test device tree compilation
+4. Verify hardware detection
+
+### Step 4: Root Filesystem
+1. Configure Buildroot
+2. Build minimal rootfs
+3. Add essential tools
+4. Test rootfs boot
+
+### Step 5: Boot Image
+1. Create boot image
+2. Test with QEMU
+3. Debug boot issues
+4. Prepare for hardware testing
+
+### Step 6: Hardware Testing
+1. Test on actual device
+2. Verify hardware access
+3. Document findings
+4. Plan next phase
+
+## Success Criteria
+
+### Phase 1 Complete When:
+- [ ] Development environment is set up
+- [ ] Kernel compiles and boots in QEMU
+- [ ] Device tree loads correctly
+- [ ] Minimal rootfs boots
+- [ ] Debug interfaces are working
+- [ ] Hardware testing plan is ready
+
+### Phase 2 Ready When:
+- [ ] Basic kernel is working
+- [ ] Hardware access is confirmed
+- [ ] Boot process is understood
+- [ ] Development workflow is established
+
+## Risk Mitigation
+
+### Technical Risks
+- **Bootloader locked**: Use recovery mode or EDL
+- **Hardware not accessible**: Focus on emulation first
+- **Drivers not working**: Use generic drivers initially
+
+### Development Risks
+- **Limited documentation**: Rely on community resources
+- **Complex hardware**: Start with basic functionality
+- **Time constraints**: Focus on essential features
+
+## Next Phase Preparation
+
+### Phase 2 Requirements
+- Working kernel and rootfs
+- Basic hardware access
+- Debug interface setup
+- Development workflow established
+
+### Phase 2 Goals
+- Boot on actual hardware
+- Basic hardware drivers working
+- User interface framework
+- Core system functionality
