Netgear GSM7352s - Image corrupted, auto reboots
Network Switch Model: Netgear GSM7352s v1 Had upgraded my switch to latest firmware 8.0.3.49 and later by mistake tried to upgrade to 10.0.0.53 (which is supposed to be for v2 version) Now my sitch...
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).
Find below status,
Options available
1 - Start operational code
2 - Change baud rate
3 - Retrieve event log using XMODEM
4 - Load new operational code using XMODEM
5 - Load new operational code using USB
6 - Display operational code vital product data
7 - Abort boot code update
8 - Update boot code
9 - Delete operational code
10 - Reset the system
11 - Restore configuration to factory defaults (delete config files)
12 - Activate Backup Image
13 - Password Recovery Procedure
14 - File system directory listing
15 - Upload a file through XMODEM
16 - Download a file through XMODEM

Error opening the image file image2
Backup Image failed activation.
Failed to activate Backup Image.
When i try to send .opr image to switch via xmodem if fails with crc error.
Kindly advice how to proceed further.
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.
You mentioned having a GSM7352s v1, that would indicate you need the firmware from here: https://www.netgear.com/support/product/GSM7352Sv1.aspx#download Your firmware version isn't shown there, even old version with 6.x show .stk files, please use one of the (if that is your switch model).
The days when people regularly used XMODEM file transfers are gone and so even I have to do some guessing. I have access to an M4100, but things might be different. I'd have to actively boot it into the boot menu.
What tool do you use when attempting XMODEM? Please post the output of the boot menu and what you did with your tool, including its output, that way there is a better chance of helping you :-)
