How to Fix Skyworth 55SUE9520 Stuck on Logo & Boot Loop (USB Firmware Update)

How to Fix Skyworth 55SUE9520 Stuck on Logo & Android Boot Loop

Is your Skyworth 55SUE9520 4K QLED Google TV frozen on the startup logo screen? Or is it stuck in an endless Android boot loop where the TV keeps restarting without reaching the home screen?

This is a common issue on Smart TVs running MediaTek chipsets (MTK9602). It usually occurs due to corrupted eMMC system files, failed over-the-air (OTA) auto-updates, or power interruptions during operation. Fortunately, you do not need to replace the mainboard—flashing the official stock firmware via USB will completely unbrick and restore your Smart TV.


🔴 Common Symptoms Solved by USB Firmware Flashing

  • Stuck on Skyworth or Google TV Logo: The TV turns on, shows the boot logo, but stays stuck indefinitely.
  • Endless Boot Loop: The TV continuously restarts itself before reaching the user interface.
  • Black Screen with Backlight On: Power LED turns green/blue, backlight is visible, but no picture or sound appears.
  • App Crashes & Recovery Mode Errors: System throws force-close errors or boots directly into Android System Recovery.

🛠️ How the Forced USB Update Works

A forced USB firmware flash bypasses the damaged TV operating system. By loading the stock software package (e.g., A.11.0.0_9602_FF_AP) onto a FAT32-formatted USB flash drive and triggering the TV's hardware recovery bootloader, the mainboard overwrites the corrupted partitions and reinstalls a fresh Google TV system.

⚠️ Important Pre-Flashing Tips

  1. Use a USB drive formatted strictly to FAT32 (preferably 8GB–32GB).
  2. Ensure the update file is placed directly in the root directory of the USB drive.
  3. Do not disconnect power while the standby LED is flashing during the update procedure.
