+### Firmware History
+
+| Version | Date | Changes | Status |
+|---|---|---|---|
+| v3 | 2026-09-14 | Original PCB_SWTG024AS_A_2_0_1 config | All ports working, LEDs wrong |
+| v10 | 2026-09-17 | LED colors corrected for RJ45 and SFP+ | All ports + LEDs working |
+
+### Known Issues & Fixes
+
+#### Issue: LEDs showing wrong colors
+**Symptom:** RJ45 ports show green at all speeds, SFP LEDs don't light up
+**Fix:** Use v10 firmware with corrected LED sets and LED mux configuration
+
+#### Issue: No network connectivity after flash
+**Symptom:** Switch boots but no ping response
+**Fix:** Ensure `.isRTL8373 = 0` (RTL8372N) is set - this device uses RTL8372N, not RTL8373
+
+### Flashing Instructions
+
+#### Via Loader Mode (CH341A)
+```bash
+flashrom -p ch341a_spi -c "GD25Q128E" -w rtlplayground-PCB_SWTG024AS_A_2_0_1.bin
+```
+
+#### Via Web UI
+1. Access the web interface at `http://192.168.2.1`
+2. Navigate to **Firmware Update** (under System tab)
+3. Upload `rtlplayground_oem_upgrade-PCB_SWTG024AS_A_2_0_1.bin`
+4. Wait for flash completion and automatic reboot
+
+### Recovery
+
+If flashing fails and the switch does not boot:
+
+1. **Loader Mode Recovery:**
+   - Hold reset button while powering on
+   - Switch should be accessible at `192.168.10.247`
+   - Flash via `curl -T firmware.bin http://192.168.10.247/firmware`
+
+2. **Serial Recovery:**
+   - Connect via UART (115200 baud for RTLPlayground, 9600 for stock)
+   - Use CH341A: `flashrom -p ch341a_spi -c "GD25Q128E" -w firmware.bin`
+
+### Stock Firmware Information
+
+- **Default IP:** 192.168.10.247
+- **Default Login:** admin/admin (varies by OEM)
+- **Console Baud:** 9600
+- **CPU:** RTL8372N
+- **Hardware detection string:** "PCB-SWTG024AS-A-2.0.1"
+
+**Note:** This variant uses the same PCB as described above but may have different component population.
