Root Rooting a Moto G4 Android 6.0.1

Hey @Hoegali, welcome to AF .

I don't specifically know anything about the Moto G4, but I have some thoughts and questions for you:

1. What exactly do you mean by "unlocked the handset"? Did you unlock the bootloader or are you just talking about unlocking the home screen?

2. If you've not previously installed a custom recovery (and it looks like you haven't), the stock recovery cannot and will not flash/install a .zip file unless it has been signed using the manufacturer's keys (i.e., literally provided by either Motorola or your carrier).

3. Not sure how the app/tool listed in the second link you provided does a signature check disabling...I'm guessing it simply strips-off some of the asserts at the beginning of the updater-script file in the flashable .zip file, which is almost always a bad idea as the assert checks typically validate that you've got the right device and version. Its likely immaterial in any case if you don't have a custom recovery installed. True signature checking (i.e., "jarsigner -v" type of checking) is done by the recovery and is not related to the updater-script file, but rather the META-INF folder inside the .zip.

4. Like I said, I'm not familiar with the G4, so I don't really have any idea if King(o) Root (or any other root method) will root your device, but you'll also have to have a custom recovery installed to install CyanogenMod. Installing a custom recovery typically requires having an unlocked bootloader and/or the ability to overwrite the recovery partition.

Your best bet would probably be to check over at XDA and see if they have a section about rooting the G4.

Cheers!

Did you install a custom recovery like TWRP?

Can you post a screen shot of the screen where you're seeing the "E:failed to verify whole-file signature" error?

If you have installed a custom recovery like TWRP, there's a "Zip signature verification" setting in the "Settings" page that you can disable.

By the way, the co-/secondary purpose of a signature check is to help you verify that you've got a whole, uncorrupted download.

So, if you're going to turn that off, make sure you've at least verified the MD5 or SHA1 sum with the information supplied on the site that you downloaded it from.

Also, re-reading your post #3 above about that "LP" app (we don't usually condone discussion of that particular app because it can also be used for nefarious purposes (getting paid apps for free)) is that you might be changing your system (i.e., the package manager) and not anything related to the .zip file that you're trying to install.
