&gt; Allwinner chips are lockdown-free even without this - you just need to hold down the right button&#x2F;pin at poweron and the ROM bootloader goes into a mode that lets you load unsigned code over USB.<p>Side-loading unsigned &#x27;ROM&#x27;s&#x2F;packages and gaining root are orthogonal concepts in Android: sometimes you want to obtain app-level root in the factory-installed OS - sideloading won&#x27;t help with that (unless you are side-loading a rooted ROM, but that is not a given)
