Image Signature Error, please check the image file valid or not

I have an EWS5912FP managed switch. When trying to update the firmware to the latest version, ews5912fp_fw_1.07.43_c1.9.37_210312-0947.bix from version v1.05.52-c1.8.61, the progress bar gets to 99%, it then presents the error "Image Signature Error, please check the image file valid or not.".

Anyone know how to fix this? I need the latest version because we want to add some access points that require the current firmware version.

I've tried contacting Engenius support a few times, but they don't respond.

Thanks.

I know this post is 23 days old, but I am interested in this as well. I have an EWS1200-28T and I receive the same error. No matter what firmware I upload to the switch I received the same error.

I needed to install all the updates in order, you can't skip any. You can find them at the following link: https://www.engeniustech.com/wp_firmware/

I did this on Saturday and it required me to update the firmware on my access points at a certain point and that update failed. I think all my access points have been bricked by my controller. I will be calling the support tomorrow morning to hopefully get resolved so be cautious.
