My Akko 5087S QMK keyboard stops working after restart unless I replug it. What should I do?

Please be aware that different keyboards require specific firmware versions, and flashing an incorrect firmware can damage your keyboard and potentially void your warranty.

Important: This firmware is only for the 5087S QMK version. Do NOT use it on other models like 5075/5087B — it will brick your keyboard and void the warranty.

1. Download the Correct Firmware
   Download the appropriate firmware for 5087S QMK from the following link: 5087S QMK Firmware.
2. Open QMK Toolbox
   • Launch the QMK Toolbox software from the download file.
   • If this is your first time using QMK Toolbox, follow the on-screen instructions to install any necessary drivers.
3. Locate the Firmware
   • In the QMK Toolbox, click the “Open” button to browse for the .bin firmware file you downloaded.
   • Ensure that this firmware file matches your keyboard model.
4. Enter Bootloader Mode
   • Disconnect the USB cable from your keyboard.
   • While holding down the ESC key, reconnect the USB cable.
   • Confirm that the “Flash” button in QMK Toolbox is active (it should appear black), indicating the keyboard is in Bootloader mode.
5. Flash the Firmware
   • In Bootloader mode, click the “Flash” button in QMK Toolbox to initiate the firmware update.
   • Wait until the message “OK” appears, confirming the firmware update is complete.
6. Exit Bootloader Mode
   • After flashing, click the “Exit DFU” button in QMK Toolbox.
   • You may then close the QMK Toolbox software.
