Does this forum need a "How to boot into recovery" thread?

Back in the old days... I had a ritual, every Sunday morning I would clear the apps cache, then boot into recovery and clear the system cache on my Droid one. Kept it running a lot smoother.
 
So far, I only know of how to do it on the Verizon version (after discovering it myself when experimenting). I've seen others try for other versions, but so far no one seems to have figured those out.

Had it well over a month and haven't had to perform any exorcisms yet.
 
I thought LG phones don't allow the user to access the standard Android Recovery menu, but maybe the V20 is different. I found a few sites like this one: How to Boot into Recovery Mode on LG V20. Can anyone confirm that this works?
I can confirm that it's having you perform extra work for the Verizon version. For Verizon, you power up as normal. When the Verizon splash animation appears (not the LG screen), that's when you press and hold power+vol down and hold. The phone will appear to do a normal reboot at first, but keep holding them and it will boot into recovery.
 
Here's how I do it on my Verizon LG devices :
Power phone down.
Press & hold volume down button.
Press & hold power button, while keeping volume button pressed.
Continue to hold both buttons until the recovery menu pops up.
Release buttons, then use volume down button to scroll down to the option you want.
Press& release power button to select that option.
The phone will do the rest.
Note : this method works for Verizon G2, Gpad 8.3, G4, and V10. I do not yet have a, V20, so I can't verify that it works for any carrier variant of the V20.
 
I don't seem to NEED to swap batteries more than about once/week, so I usually boot into recovery and clear the cache when I restart the phone after a battery swap. Takes about 20 seconds longer than simply restarting.
 
I'm going to correct myself for Verizon. I was just trying to find the combination for pulling up the barcode when I found out they changed the recovery method. When shut off, simply holding power + vol down boots almost immediately into recovery. That must have changed with the last one or two updates because that didn't work when I found out the first method I mentioned earlier (doing it this way was the first thing I tried back then and it didn't work).

Just had a situation where I needed to clear my system cache, this afternoon. Downloaded a Verizon update on my G4, visited a forum & my back button wouldn't return me from a thread to the main page. Cleared the apps cache, no joy.
Cleared the system cache, problem solved. Maybe just restarting the phone would have worked, but I didn't try that.
 
It's kind of crazy that we can't do this on an AT&T variant. I've searched all over and can't seem to figure out how to do it. I've also tried about 10 variations of the steps in this thread with no luck.
