There is no "Method or process" for doing this, as it depends on where the cable is broken at, and if you knew that, you could elimate everything up stream from there. I have had this problem, in the past, and all I can tell you, is sometimes you have to remove; the bumper, the grill, sometimes the A/C condenser and anything else that is in the way of getting to the latch assembly. A pair of those long ( and I mean long) needle nose pliers, can be worked into a position where they can grab the end of the cable or the latch. The hood can be opened, without destroying it, but it takes patience and persistance. Usually a few friends and a couple of 12 packs gets it done. Just think, after you win this battle, you'll have something else to eyeball, every time you open the hood...............GOOD LUCK

HOW DO I OPEN HOOD ON CAR WHEN CABLE IS BROKEN
how to open hood with a broken cable on a 1994 ford explorer
If the cable isn't broken then you shouldn't have any issues opening the hood...
you get the cable fixed then open it

Try getting at it from underneath or might have to pull the grill if you can. If it broke at the handle inside the truck try pulling the kick panel and see if theres enough cable to get a pair of pliers on.

If the hood cable is broken on a Geo Prizm, the only option is to open the hood from underneath the vehicle. It is best to put the car up on a hoist and use a pole to trip the hood latch.
If the cable release is broken for the hood on a 2002 Kia Spectra, a person could crawl under the car and see if they can locate the broken part of the cable. If it is still attached to the hood, they could pull it to trip the hood latch. Otherwise, the car will have to be put on a hoist, and a long pole used to trip the hood latch.
Hood release cable has connector nuts on both ends of the cable. Loosen the connector nuts. Remove the cable retainers. The cable will come off and can be replaced with a new hood release cable.
If it is just the plastic handle broken, behind that is the cable that opens the hood. Just grab the cable with a pair of pliers and pull. You can probably just replace the inside handle and not have to run a new cable.
