BDL4550D - FORCED Firmware Update Procedure

Whenever possible, use the normal Firmware update procedure.

ONLY if you can't get into the android menu you should use this procedure.

Copy the MstarUpgrade.bin file to the root directory of a USB stick formatted in FAT32.

Procedure:

1. Plug in the USB drive to the screen.

2. Power On the Screen (from the main switch - not the remote).

3. While the screen boot up, continue pressing the "INPUT" button on the key (behind the screen)

4. Screen will show upgrade in progress.. Wait until this process complete.. (if not, begin from step 2 again)

Some USB drives do not get detected by the screen. If the screen fails to recognise the update file, try a different USB drive.

Verify the firmware has been updated by pressing INFO, 7, 7 buttons on the remote.

Philips recommends a factory reset after a FW update has been performed.

However, doing so will wipe out all the apps installed and all Android settings.

Most of the time, not doing a factory reset will not cause issues.

If you do have apps running in Android, it is best to test the screen's behaviour without performing a factory reset.

Factory reset

Press the following remote button sequence to enter the factory mode: HOME, 1, 9, 9, 9, BACK

Navigate to Factory Reset setting and press OK.

Select YES to confirm and initiate the factory reset process. The screen will turn off after the reset has been completed.

Turn off the power to the screen from the mains power switch and turn it on again.
