remount with wr privileges. How?

Hello everyone, I've been using android since Eclair and I had a couple of different brands under my ownership. Sony Ericsson, Samsung, Alcatel...

I've always been rooting my phones. After that, each time I needed rw privileges in order to be able to delete files (like built-in apps), place ringtones, alarms and notifications sounds directly into /system/media/audio, rename or backup system files etc., I was using a simple command from a terminal app or via ssh from a desktop giving this syntax:
mount -o remount, rw /dev/block/mtdblock3 /system
Then, until next reboot I could write in /system.

Unfortunately since I got G3 this command won't work. Apparently, either lollipop's or LG's partitions are a bit different that the usual...
After looking around for a while, I came up with a page which shows that this command "ls -al /dev/block/platform/msm_sdcc.1/by-name", lists all partitions' paths by label and that according to the list, /system corresponds to mmcblk0p40. So I was thinking of trying the command a bit altered, like this:
mount -o remount, rw /dev/block/mmcblk0p40 /system

Since I don't have good knowledge of linux -I can't even tell if the old syntax is not working because of LG's implementation or of android's new version (lollipop)- I'd just like someone who has already done this to confirm that I'm right and it works. I'd really not like to brick the phone atm. I feel too old for this s...
Thanks, George...

P.S.: Now, if someone would be kind enough to provide an in-depth explanation of how I could always find by myself (in any newer version of android and any different android implementation), which partition is the appropriate one to use in this command in order to obtain rw for /system, that would be more than welcome!
