Are white potatoes the right type for hash browns? I guess not as I couldn't get them to adhere, without using eggs or flour etc.
I'm assuming you're talking about shredded style hash browns. I'm not sure how much potato variety affects the outcome, as I tend to buy yellow potatoes (as they can typically be used either for roasting or mashing, so I don't have to think about how I'm going to use them in advance). I'm also more likely to make 'home fries' style hash browns, but I did a bit of research & testing for my pancake demonstration
Most recipes for this style call for soaking the shreds in water to remove the starch, then wring them out in a dish towel or similar. You can get sometimes get better adhesion if you don't soak them, but still wring out as much water out as you can.
If you're making latkes, you'll want a bit of depth to the oil, but generally 1 to 3 tablespoons of oil or butter is enough for hash browns, depending on how large of a surface you're working with.
Make sure the crust is nice and brown before flipping. Also, make sure that you're flipping it over in chunks suitable for your spatula size (either divide it up into quadrants or similar if coating the entire pan; or make individual piles only slightly larger than your spatula). If the potatoes drank up all of the oil when cooking the first side, it's generally a sign that the heat is too low and you might need to add some more (before you flip, so it has a chance to heat up)
The exact temperature to cook at depends on how much you're trying to cook at once, how fast your pans recover after putting the food in, and how thick of a layer you're cooking. (you want to make sure that the middle is cooked before you've burned the outside; if you're having problems with this, you can also par cook the potatoes in a microwave first).
If your pan/burner combination has a particularly slow temperature recovery, you might want to get the oil up to shimmering before you put in the shreds, but you typically aim for a little lower than that.
