How To Upgrade Or Flash Skybox/Openbox Satellite Decoder Using Serial RS232 Null Cable

Here are some simple steps that you can follow to get it done.

Typically, Openbox/Hibox/Skybox/Yumy S9 HD is equipped with USB 2.0 host port that users can plug an external USB thumbdrive to perform the upgrade from USB, but this may not always be the case especially when the decoder is stuck at boot-up where users are unable to enter menu or due to defective USB port.

i. First, get a null modem cable and connect to the RS232 ports of both the PC and decoder.
ii. Then, download the EromUpgrade.exe and launch it.
iii. When comes to main menu, enter the port (Com 1, 2 or etc), bit rate as ‘115200’, operate mode as ‘Upgrade’ and browse to the correct firmware file (.abs or .bin) with a tick on ‘Bootloader’ box.
iv. With the decoder in Off state, press ‘Next’ button on the screen and turn On the decoder. Follow the instruction on the screen with progressive bar indicating the percentage of completion.

Once done, you should be able to get a new firmware loaded into decoder and hopefully this will able to help you recovering from any hang issue related to software/firmware.
