Best method for editing build.prop

So I've noticed the LG G4 build.prop size of 11.24KB, however, if I try to edit it in say build.prop editor, or root file explorer, it shrinks it down to 10.2KB which will result in boot loops unless if I restore the backup I have.

I never encountered this problem on my other phones (this is my first LG though)

Bootloop from editing build.prop

Hi guys,

I'm worried I really effed up as I've never been stuck in a bootloop before on any of my devices.

I was editing the build.prop to add dual window functionality to all of my apps as per this video https://www.youtube.com/watch?v=Z4X2...dex=35&list=WL

And now my phone is stuck in a bootloop. I keep getting a message saying that Android is updating app X out of 38 and it goes back to the LG splash screen.

Sure enough there's a warning at beginning of that youtube video saying BE SURE THAT BUILD.PROP IS NOT TRUNCATED AND ITS PERMISSIONS ARE RIGHT BEFORE REBOOTING! - I'm assuming this is where I've gone wrong.

I'm using a Canadian version of the phone LG-H812 for Bell. Do I have to return the phone to stock to get out of this? How do I go about doing so?

Help!

Stuck at T-Mobile logo after editing build.prop

As the title says, I edited the build.prop file to enable splitscreen for all apps and restarted my phone. Now, I am stuck at the T-Mobile logo, even after trying to reset the phone (by holding down the power button + volume button).

What can I do to reset or fix this?

Bootloop After Editing Build.PROP

Hey everyone! I bricked my lenovo A5500-H after editing the davlik vm heap size to 1024m! I forgot my limitations . Anyway i want to know what id go about doing now. I need to reflash anyway so if anyone could give me the(and this is the thing) the a5500-HV firmware so i can make calls. I'd also like a step by step tut because the only thing ive ever reflashed is a Samsung S5300 and that was like three years ago XD.
Thanks
