Get from Rooted Lollipop 13b to Stock Marshmallow - Verizon LG G4

I'm tired of the problems and struggle I've had attempting to use my rooted G4. I'm currently on 13b rooted and it's been giving me problems. It randomly reboots and doesn't start up at times. And it's so sluggish. I've gotten a replacement because I flashed the wrong kdz. I just want my phone to work without all these problems. I just want to get to the stock Verizon MM for my G4. Is this possible?

You should be able to flash the MM kdz - they can be found here in the general section. Be sure to verify it is the correct kdz.
Keep in mind once you go to MM you won't be able to achieve root without downgrading back to LP. I think there is a downgrade thread here in general as well if you need it.

Thank you I just downloaded the KDZ and flashed via LG UP. It installed without any problems. I'm aware that you can't root on MM, I'm ok with that. I need a break from rooting after all of this. Thank you I appreciate it!

Glad to see someone here not happy with rooting the G4. I don't find it worth the risk or the benefits worth it without the ability to flash custom roms. I've never rooted a phone without there being a way to install a custom recovery.
For anyone interested, The Android Central podcast discussed the topic of rooting and flashing roms a bit on their most recent episode. Most of them agreed that there isn't as much of a need anymore to root and flash roms and that it's kind of died down a bit. Features that people used to have to root their phones for are now available on most stock roms.

i know at the end of the video it says close the app, but dont, just start it and you be upgraded to MM in no time just make sure upgrade is checked
if you want to start fresh, then you can just do what my video says to get refurbished checked
if you upgrade with a rooted rom you have to factory reset your phone inorder for MM to boot

LG G3 VS98535B (5.1.1) safe for update if rooted?

I have a lg g3 (verizon) with 5.0.1 rooted. Is it safe to update to 5.1.1? Has anyone tried? I want to but im afraid it'll break my root completely or my phone will brick. I can't lose my root because ill lose a lot of features. So if someone has tried or is willing to try that'd be awesome!
Same boat. I'll be watching this for an answer.

Reflash stock recovery and you should be fine
OTA usually removes root. You can reroot it after you install the OTA
No update for the d855 or other versions ?!

I have the Verizon G3 with 5.01. The 35B OTA wouldn't even install until I restored the factory image.

Well I recommend a clean TOT or KDZ flash. Hope this will fix your problem. Please do follow this post http://forum.xda-developers.com/show....php?t=2785089 to flash TOT or KDZ then update via OTA. Thanks!
DO NOT TAKE THE UPDATE
...if you want root, etc. Currently there is no way to root 35b and no way to roll back to an earlier version. They patched some things up it seems.
Some brave souls took the update and are stuck now... http://forum.xda-developers.com/ver...-5-1-1-ota-t3220693/post63200915#post63200915
Freeze with tibu (or delete) the system update apk to stop the notification.

I just update my rooted 5.0.1 VS985 to 5.1.1, gotta say , this new system is more battery save. i turn on the music and LG health and mobile data when i took exercise tonight for about 2 hours, and it's only cost 3% of the battery.and you know,lots of useless Verizon apps and others, but it's fine, i can disable it in app manager.
Yea I noticed that with this new update as well.
I'm little sour about being in un-rooted state.
But the battery life is noticeably better.
Maybe this option was there but I noticed new options under the developer setting where you can restrict amount of background apps running. I believe this helps out a lot as well.
Just an update on the update...
On vs985 it looks like someone was able to successfully TOT back from the 35B update, so people shouldn't be stuck anymore if they took the OTA(see post 84 here... http://forum.xda-developers.com/ver...ing-takethe-vs98535b-5-1-1-ota-t3220693/page9). Root is still not available for people who took the 35B OTA yet, but there are 2 stock based rooted 35B ROMs available now: Jasmine and Skydragon. I think the only thing that isn't functional is advanced calling because we can only use the 24b modem with the 35b ROM due to the 12b bootloaders we have that allow us to have TWRP...or something like that. So it'll be a 35b ROM and all it's updated glory - running a 24b modem.

Help new to this!

Have you unlocked your bootloader ?
No not too sure how to do that. Any good threads you guys reccomend.
Many thanks
So I know this is scary for you and because it is something new, therefore be sure that you want to live with the responsability if something goes wrong.
Now, the next forum thread tells you how to flash an already rooted image BUT, and this is very important, this works only if you have the version 10c installed (Check in About Phone>Software Version)
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
If you have the latest version of the software (20a) the best thing is to unlock your bootloader, void your warranty in the process, and flash a custom recovery. After that, you just need to flash the SuperSu zip file and you will have root.
To flash custom ROMs, just access recovery and flash the zip file of your ROM.
I'm using the unofficial CM13.0 and works very good for me, but I do miss the official camera app.
Thankyou very much for your advice okarr. Will look into this

Upgrading Modem?

Hello all. I recently spent 5+ hours rooting and turning my VZW Note 4 into a "developer" phone. I've rooted a lot of phones, but this particular process had me pretty frustrated. I had several problems with the software versions I was using. Anyway, I'm curious if I should upgrade just my modem firmware to the latest included in VZW's 6.0.1 release. On my old Android devices, I used to do this with great success. Signal strenght would increase (or worsen), GPS signal would be better, etc. Is this included in ROMS and/or is it safe to do this?
Oh man,lol don't tell me that. I just bought a note 4 off swappa and it'll be here wendsday probably. I have been wanting a note 4 for along time. Only reason why I never got it was because of root and BL being locked down. Now that there is custom roms & kernels I bought it and can't wait to get it. Is it really that bad to Root and BL unlock? If it took you that long it'll take me days because I work 12hr job 7 days a week. I'm just trying to find all the necessary files I need to download now that way that will be done with.

Look in @hsbadr's Jasmine ROM thread. There's a partial firmware to flash that will update both the bootloader and the modem to PF3, which is the latest and greatest. It's required if you want to use Jasmine 7.0 or @chevyrhoad's Grace 7 ROMs.

It's a matter of being familiar with the tools. The process is pretty rudimentary. If you have a knowledge of linux and/or abd you'll be fine. I had trouble when my phone decided to start boot looping. Turns out it skipped my mind to wipe the cache/data clean after a stock odin flash. After all is said and done, the process is fairly simple. Also, King Root is a big issue. If you dump a fresh ROM from odin onto your device, install King Root, and attempt to root it it will root successfully everytime, the first time. On some other ROMs it can give you a considerable amount of trouble. I recommend resetting your lollipop to defaults, rooting it, flashing to the 5.1.1/6.0.1 hybrid, rooting again, and then continue about your business. There's a certain set of steps that makes this process painless which you can only ascertain if you have done it.

Can I flash "N910VVRU2CPF3_PartialFirmware_PatechedKernel.tar.md5" from his thread overtop of my TRWM and CM 13 ROM? I have both installed, and I'm wondering if I can just boot into the bootloader and odin this to the phone. CM 13 supports it, so why not? I'm just worried about it a kernel malfunction.

I will absolutely take you're advice on this and apply it as soon as I get my note 4. Should be receiving it in about 3 or 4 days.

To the best of my knowledge, it does nothing to the kernel. All it does is upgrade the modem.

This thread will tell you how to downgrade from MM to LP. It works. I had the same problem you did.
Yep, That worked for me. You need to "return to stock" like post above and downgrade the firmware. Use the 13b firmware stock, so you can just flash over it with the 13b rooted file. Easiest way i found. And That is the program that MUST be used. The other way WILL fail every time.
We just need a UNLOCKED BOOTLOADER so we can custom recovery like TWRP and start flashing ROMS!

Help upgrading from root kitkat to marshmallow

Hello I'm currently running 4.4.2 with root and I've been thinking about upgrading to marshmallow. I just wanted to know whats the best way going about it. I'm assuming that I'm going to have to re-enable the software updating app that I disabled for I didn't get OEM updates then upgrade to marshmallow and re-root using one of the guides or would a root keeping app or Survival mode on superSU possibly work? I also believe I have TWRP installed from when I rooted my phone before, I'm not sure if that's important info. Also side note, would their be a way to keep the 4.4.2 touch buttons on the bottom of the screen? They make more sense to me then the new ones. Device info below
AT&T
android 4.4.2
software version D85010d
Model number LG-D850
You can't root on marshmallow so if you want root DO NOT update with that app. the easiest way is to just flash a rom. i have the verizon version (vs985) and all i have to do to flash a custom stock rom, is to flash the right modem before flashing the rom, then flashing modem again after the rom and bam, i just flashed a marshmallow rom from kitkat 4.4.2. you can also downgrade that way just flashing the appropriate modem before and after and bam.! but i dont know about your version, you should definitely check the att&t G3 subforum. you need to be careful and read thoroughly so you don't brick. the thing with vs985 is that there are modems out there that can hardbrick the device, however, it may not be the same for others but, just in case you should read.
Thank you I'll look into that. So far I found this https://forum.xda-developers.com/att-lg-g3/development/rom-stock-bumped-marshmallow-v30a-t3661194 but I still got more research to do since I'm unfamiliar with flashing modems and whatever "bumped" is exactly. Hopefully this weekend I'll have more time to look into this.
