Is there any other way to downgrade the UHD image?
Kind Regards,

The above simply installed the FPGA images onto your *local* host, which
will have no effect on the E312.
I'm talking about the UHD software package on your host machine must
match what you have on the E312.
Perhaps you mis-understand what the E312 is? It has a built-in Linux
host. The intended mode of operation is to run
software *on the E312 itself*, and so-called "network mode" allows
you to use the E312 like any other network-connected
USRP (like an N210, etc), but at *much* lower bandwidth. We don't
recommend network mode for anything other than
initial check-out.
Perhaps this would be useful?

Hi Marcus,
Appreciate your response!
When I use my Linux PC as host, it also has the same issue, so I
tried to implement your suggestion in both MAC and the linux pc.
In both the cases, when I tried to downgrade the UHD image, it
says Checksum failure :

Do you think its expected behavior since the gnuradio version
could be not compatible with this downgraded one?

However, the other device is working as expected.

Can you please help me with figuring out how to solve the
issue with this device?
Thanks in advance!

This looks like you're using Network Mode with your E312 from
a Mac. The version of UHD on your host machine and E3xx MUST
be the same when
using network mode.
If you are going to use network mode with your E3xx (with the
proviso that network mode is useful only for check-out and
low-bandwidth testing), then
downgrade the version of UHD on your Mac to match that on
the E312.
