Troubleshooting WiFi and Data Connectivity Issues on Xiaomi Mi 15 after AK3 刷入 6.6.30

### Mi 15 WiFi and Data Not Working After AK3 Flashing 6.6.30 Firmware

You've flashed your Xiaomi Mi 15 with the AK3 6.6.30 firmware and are now encountering problems with your WiFi and data connectivity? You're not alone. This issue is a known problem for some users after upgrading to this specific firmware.

Don't worry, there are several troubleshooting steps you can try to get your internet connection back online:

**1. Check for Official Updates:**
The first thing to do is check if Xiaomi has released an official patch for this bug. Head to your Mi 15's settings > About Phone > System Updates, and see if any newer firmware updates are available. Installing the latest update might resolve the connectivity issue.

**2. Wipe Cache Partition:**
Sometimes, a corrupted cache partition can cause connectivity problems. Try wiping the cache partition on your device:
* **Turn off** your Mi 15.
* Then **boot into recovery mode**. This usually involves pressing a combination of buttons during startup (refer to your phone's manual or online resources for the exact combination).
* Use the volume buttons to navigate to **Wipe Cache Partition** and select it using the power button.
* Confirm the operation and wait for the process to complete.
* **Restart** your device.

**3. Reinstall the Last ROM:**
If wiping the cache partition doesn't work, you might need to reinstall the last working ROM you had on your device. This involves flashing the ROM again, so make sure you have a backup of your important data.

**4. Seek Community Help:**

Online forums and communities dedicated to Xiaomi devices can be incredibly helpful. Search for your specific issue on websites like XDA Developers or Mi Community. Other users might have already encountered the same problem and found a solution.

**5. Contact Xiaomi Support:**
If all else fails, reach out to Xiaomi support directly for assistance. They may have specific troubleshooting steps or solutions for this issue.
