Here is the screen shot of the Screensaver Tool Utility:
Please keep in mind the limitation of the image.bin file. Once the file is generated by this utility tool,
please put the file into the same folders containing firmware files.
The screensaver image flashing follows the same way of firmware flashing, either TFTP or HTTP. But
if the firmware is already the latest one, user can just put the only one file “image.bin” there to allow
the phone to get it.
Be advised do NOT interrupt the power supply when doing ANY file flashing as that will risk damage
the phone. Users with high frequent power outage are recommended to have UPS hooked on before
doing any firmware or screensaver or ring tone flashing.
