Upgrade v50010A to v50020b - G Pad 8.3 Q&A, Help & Troubleshooting

Hope that someone can help me.
After a long struggle to get my Pad rooted, I managed that after downgrading from V50020D to V50010A.
Now it seems my battery life is very bad, so I would like to upgrade to V50020D again.
Is that possible, and what is the best way to achieve that? I want to stay rooted, and I want to stay running Android 5.0.2 Lollipop - 20150106 - LRX22G 1 2 3 
Please advice.

[Q] LG G3 Lollipop Root - Help

Hey guys at xda-developers!
So before christmas I recieved an update for my G3 to upgrade to Android L from a rooted KitKat and I want to become rooted again. So can anylne advise me on what to do.
If there is any simple rooting method for LG Android L update.
I want to keep all my data btw.
Thanks. Ask any questions
Im new to the android world and xda so i dont know too much about ANDROID but i know a good amount
Thanks!
You can't root on lollipop, no root available as of yet. If you want root you have to downgrade to kitkat with the flashtool.
Use the LG Flash Tool to downgrade to kitkat (with a 10r build). There are a plethora of guides on how to do this.
Then you root, and install a custom ROM to get back to Lollipop. Cyanogenmod 12 works amazingly well on my D851. It's smoother than the stock ROM. However, you might be able to do the CloudyG3 ROM, which is essentially just what you have now with added features. Assuming that you got the Lollipop update a little while back, your phone sounds compatible. However, if you don't use the QuickCircle Case, I would highly suggest Cyanogenmod 12. I used the case, but made that small sacrifice for this amazing ROM.
Hope I helped!

Help LG G3 S D722 Stock Firmware

Hello XDA! First I want to say I am not new to rooting but I'm still noob at it.
So here's my problem. I've rooted my LG G3 S D722 (I don't know if it is known as Beat) 3 months ago and I wanted to unroot it today for a software update. The only problem is that I haven't unrooted it correctly. Now I can't root it anymore (or I don't know how). Anyway I wanted to unroot it so I heard a Hard Reset will unroot it but it wasn't like that. After I hard reseted it, a game app which I really like it keeps giving me crashes and I don't know what to do.
I'm thinking that my last solution is to downgrade the software to the stock firmware but I don't how, again. I've searched 12 hours today and I couldn't find anything brilliant and 100% working without breaking the device.
Device : LG G3 S D722
OS: Android
OS version: 5.0.2
ROM: Lollipop
Kernel version: 3.4.0+
Bandbase version: MPSS.DI.2.0.1.c1.15-00044-M8926DAAAANAZM-1
Compiler Number: LRX22G.A1440040099
Software version: V20d-EUR-XX
The point is I want to downgrade it to stock firmware first. If I can't do that I want to root it again (if it is possible) and install a custom ROM, but I would prefer the stock unrooted firmware. Any help?
Thanks in advance!

G Pad 10.1 LG-V700 ROOTED, but no recovery?

LG G Pad 10.1
LG V700
Kernal: 3.4.0+
Build: LRX22G
Software: V70020c
Android Version: 5.0.2
I was able to run King Root and get it rooted. It was an unstable root until I installed Xposed Framework. Now ROOT seems stable, but there is no way to Flash TWRP...
I have read that we have to downgrade to Android 4.4.x in order to get TWRP (or any custom recovery) to install. Is this true? LG won't unlock bootloader? This seems like a pretty nice device, I have had Galaxy Tabs and I was thinking I like this better, except for the ROOT/Recovery situation..
Is there something I am missing? No one is really dev'ing for the V700?
Advice would be much appreciated.
To get twrp u need to be on kitkat... But its useless since there isnt any roms for it.

Is it worth updating to marshmallow 6.0 from kitkat 4.4.4?

Pretty much as the title states, is it worth updating to marshmallow from kitkat? My phone has been running incredibly slow, and maybe it's time for a factory reset but should I just update to marshmallow? Thanks for your feedback.
My wife's Note 4 is having serious battery issues since it updated to Android M (as are others according to posts here) so I would recommend holding off until it is patched.
