Restore USRP2 images to support old USRP2 (Not UHD) code

Hi All,

I have burned the USRP2 to support the UHD, but now I need to run some
old
USRP2 code.
The new burned USRP2 images don’t support the old code. So, is there any
ways I can restore
USRP2 images to old version to support the old code?

Any help is appreciated, thanks in advance.
