Apolosign Smart Portable TV Firmware Flashing Guide (System Reinstallation/Upgrade)

Updated

⚠️ IMPORTANT WARNING

DO NOT flash the firmware unless it is absolutely necessary. Firmware flashing carries a significant risk of "bricking" your device (rendering it permanently unusable). If your device is functioning normally, we strongly recommend against manual flashing.

Compatibility Check

Not all devices support manual firmware updates. Only the specific versions listed below are eligible for this process. Attempting to flash a non-supported version may cause hardware failure.

  • How to check your current version: Go to Settings > About device > Build Number

Notes (Read Before Starting)

  • Backup Data: Flashing will wipe ALL personal data (apps, accounts, files). Please back up first.

  • Use Quality Cable: Use a high-quality USB-C cable. A loose connection is the #1 cause of device failure.

  • Constant Power: Keep the power adapter plugged in. Do NOT rely on battery; power loss can permanently "brick" the device.

  • Stay Connected: Do NOT unplug the cable or turn off your PC until the update is 100% complete and the device restarts.

 

⚠️ IMPORTANT: 

Manual firmware flashing is performed at your own risk. 

Apolosign shall not be held liable for any hardware malfunctions or "bricking" resulting from improper execution of these steps.
