Root and locked bootloader

[algarues]

In the old days, it was possible to root an android phone even though the bootloader was locked.

For instance, i owned a motorola Droid 2 / Milestone 2. Nobody ever managed to crack the locked bootloader.
However, it could be rooted, custom recovery and tweaked kernel.

Why is nothing like that applicable to the p10 / p10 plus unless the bootloader is unlocked?

Because there are very few exploits in the newer versions of Android.

Once you open bootloader you have access to install ROM/kernel etc via ADB. Which will lead to rooting etc.
