If your GX6605S HW203 receiver is showing an “Error occur!” message during a software operation, the problem may be related to software compatibility or an incorrect firmware version.
In this guide, we explain a practical method for checking the receiver software and performing a software downgrade through USB when a compatible previous version is required.
GX6605S HW203 Error Occur Problem
The GX6605S HW203 platform is used in different satellite receiver models. Although firmware files may look similar, the hardware version and software compatibility should always be checked before installing a file.
The following points should be checked:
Receiver hardware version
Current software version
Firmware file compatibility
Correct USB file
USB flash drive condition
Upgrade or downgrade mode

Software Downgrade Method
Before starting the downgrade process, keep a compatible firmware file ready and make sure the receiver has a stable power supply.
Step 1 — Check Receiver Information
Open the receiver’s system information page and check the hardware and software details.

Step 2 — Prepare the USB Drive
Use a reliable USB flash drive and copy the required firmware file to it.
Keep the firmware file in the appropriate location on the USB drive according to the receiver’s upgrade menu.
Step 3 — Open Software Upgrade
Go to the receiver’s Software Upgrade option and select the appropriate USB/software upgrade mode.
Select the firmware file and start the process.
Step 4 — Wait for the Process
During the upgrade or downgrade process:
Do not remove the USB drive.
Do not switch off the receiver.
Do not disconnect the power.
Wait until the process is completed.

Error Occur After Selecting the Software
If the receiver displays “Error occur!”, do not repeatedly install random firmware files.
Check the following:
Is the firmware specifically compatible with GX6605S HW203?
Is the software version suitable for your receiver?
Is the USB drive working correctly?
Is the firmware file complete and undamaged?
Are you using the correct upgrade mode?

Software Downgrade Successful
After using a compatible firmware version, the receiver can be checked again from the system information menu.
If the receiver starts normally and all required functions work correctly, the downgrade process has been completed successfully.
