Hello,

Very few, which is why exploiting Dirtycow to root a phone without unlocking the bootloader became virtually impossible.

So we have to first unlock bootloader then apply dirtycow correct!

@walkman4321 once you unlock the bootloader, you can just do one of various root methods available prebuilt for your device.
