There is a mopre complete description at jaguarforums.com, but essentially you have to remove the bottom cover just under the front end, 16 or so screws. then you need to "fish" a pole or rod to the bottom of the latch. There is a feature on the botom of the latch that needs to be pushed from passenger side to driver side and the latch will pop.
Before starting this I would suggest you make sure the cable is broken. It is common for winter driven X types to have their cables rust, I sometimes have to hold my release lever for 8-10 seconds before the hood latches will pop - good luck.

Bonnet is English for hood
If the cable to open the bonnet on a Skoda Octavia is broken, you may need to access the release mechanism directly. One way to do this is by locating the release lever or latch underneath the dashboard on the driver's side, near the footwell. You can use a tool such as a long screwdriver to carefully manipulate the latch and release the bonnet. It is important to exercise caution and precision to avoid damaging any components while attempting to open the bonnet without the cable.
It will cost you a few hunderd quid to get this sorted by renault... or get some handy person to get the bonnet open, and using a cable tie connected to the passenger side bonnet release, connect said cable tie, and let the end poke out from the bonnet. This then becomes your new bonnet release. Any eagle eyed person with the knowledge will be able to open your bonnet from the outside. So do be wary of this solution. But it only costs a few pence for a cable tie vs a few hunderd quid from reno.
