Girish I checked the page and could not find 3.95 , is your firmware 3.95 Gen or Gen-2 ?
I read somewhere that 4.0 Gen will be coming soon. Maybe you can wait till then.
You can try one thing , if you have any homebrew plugins enabled then disable them from recovery menu and try again with the upgrade process.
-----------------------
There is a option for network update mode in the recovery menu for 3.95 gen, options available there are Sony, GEN and M33 try selecting m33 and then update. Seriously i dont know a thing abt 3.95 gen , do it only if you know what you are doing. I read this somewhere so suggesting it.
---------------------
From what i have read so far GEN team modifies DA's CFW, so they will be releasing 4.0 gen soon as DA already released his CFW. Still you can try as there is no restriction that once on GEN then you have to be always on GEN. See this link
