I thought I'd crosspost this here for once, as I don't think RCT, the Root Checker Tool, is going away. Please note that the original Spirited Away is not my work and is used with permission. This post pertains to the Verizon-sold LG Lucid 2 (VS870). -k0

Spirited Away: RCT Nerfer Edition

With thanks to Dan Rosenberg and the original Spirited Away he created!

Root! Root, root root, root.

Verizon doesn't want you to have it. The OUDHS does! At the behest of everyone's favorite giant, oligopolist, anti-consumer, borderline-evil carrier, LG stuck what they call the Root Checker Tool (RCT) into the guts of the Lucid 2. Not present on the international model, the RCT checks for - and perhaps prevents the execution of - certain root tools. It also leaves logs of the presence or running of said tools. See the second post for more details.

This package cuts off RCT's head and gives you - not your carrier or the OEM - a bit more control over your phone. This does not unlock the bootloader, unfortunately. It's just root.

Instructions​

Download the package.

Extract the contents of the zip.

Ensure you have installed the drivers for your phone.

Connect it to USB, wait for it to be detected.

Double-click run.bat, follow on-screen instructions. Mac and Linux users, open the file and follow along, it's just a set of ADB commands.

Let it finish, continuing to follow instructions.

That's it! Your device will autoreboot. You will be rooted.

FAQ​

Q: What does this install?

A: Your device will have Superuser (ChainsDD's variant, the original), the su binary, and BusyBox 1.20.2 on it.

Q: Can I use this on a device that isn't the Verizon-model LG Lucid 2?

A: That's a bad idea. Don't do that. Don't whine to us if you break stuff by doing so.

Q: Will this survive OTAs?

A: Probably not, and it's almost guaranteed that RCT will come back with a vengeance! Be very careful with updates!

Q: I've tried to root already, can LG/Verizon tell?

A: Unless you reset what's already been written, they sure can. See the next post.
