If you have access to the serial console I suggest stopping at the the boot loader and then try booting into the backup image. Once you have stopped the regular boot process and have entered the boot menu you should be able to boot the backup image (which hopefully doesn't contain 10.x) you can set the default boot image to be the backup image and then update your previous default image back to 8.0.3.49.
The menu is bit different between different models, there are always some similarities, hence the link for the M4100 series: https://kb.netgear.com/15115/M4100-Boot-Menu
If for any reason you have ended up with 10.x on both images, you might have to resort to XMODEM, though possibly not needed (I hope so).

Edit - didn't catch the error message when you attempted loading the backup image.
The firmware image 8.0.3.49 has a .stk file extension, not .opr as you mentioned.
I always mess up what up and download means, one of these 2 options should allow you to send send/upload (from perspective of your computer) the .stk file to the switch. (I used Tera Term's File -> Transfer -> XMODEm -> Send...)You might consider changing the baud rate in the boot menu (2) and on your terminal emulator since most older switches like yours defaulted to 9600 baud and uploading the firmware with the maximum speed is going to take significantly less time.

Below is the error message what i get when i enter option 12
[Boot Menu] 12
Error opening the image file image2
Backup Image failed activation.
Failed to activate Backup Image.When i try to transfer file using xmodem it fails.
But when i try to transfer file just normally (send file) i am able to transfer it.
I have gsm73xxs-6.2.0.6.opr file, can i transfer (send file) it without using xmodem.
