Hi all, first post here. I've tried to research on how to successfully downgrade to Android 6.0.1 (stock firmware came on phone) but the articles/guides seem outdated. I'd prefer to stay away from root, and I've heard of programs like LGUP and needing the .kdz file, but those are foreign to me..
I'd like to downgrade because I was really satisfied with the phone when I got it last Friday, but after 2 days, it did an auto upgrade without even me being aware of it until it was halfway through. Now it's sluggish, slow on switching apps, slow on opening Messages, slow on clearing all apps, etc. My battery life has dwindled also.
Is there a "safe", no root method, easy to follow guide to downgrade back to the stock firmware I had, Android 6.0.1? I'm not Android savvy, I left iPhone for this phone, because well I was tired of paying for such an expensive phone I didn't like at all.
Thanks for the help. If there's anymore info I need to provide, please let me know and I'll see if I can find it.

So, the other day I got the 5.0 OTA on my rooted 4.4.2, and I naively updated it, without knowing that:
1 - I'd loose root and my recovery
2 - There's no way to root 5.0
After two days of trying stuff, I finally understood what many people know, I suppose, but I couldn't see it written clearly anywhere, so I thought I'd share. You have to:
1 - Flash back 4.4.2
2 - Root 4.4.2
3 - Flash a custom recovery
4 - Flash a rooted 5.0 from custom recovery
I now have a rooted 5.0
Here. It's not very complicated to do, but maybe it's so obvious for people who know it that they never care to put it like this (I'm not complaining, I actually did find all the information I needed on XDA and learned a good deal of things about my phone on the way so it's cool).
You cant.

Sorry I lack experience so much with the forum that I posted without any content initially so you must have thought that I was asking for the solution. I get that you can't simply root 5.0, but you can actually get 5.0 rooted if your phone has 5.0 non rooted by switching to 4.4.2 first, which is really what people want to do when they ask that question. I have seen your answer before, and almost gave up trying, but I'm glad I insisted. Just saying "you can't" is just being deliberately unhelpful (or not knowing what you are talking about).

Yeah, there was only name of the thread and word "So"
So I thought you were looking for solution :laugh:
Some more information on how to get there:
To get 5.0 rooted, you need to:
- take note of which 5.0 version you have on your phone and check you can get the bumped image somewhere, if you want to have exactly the same at the end.
- update LG PC Suite or at least the Windows drivers for the G3? Honestly I'm not sure how important this is, since I was playing around for hours and I did that in the process, maybe it's necessary. It is necessary to have the drivers installed at least.
- find the 4.4.2 version of the ROM for your phone (mine was V10e-EUR-XX), versions are different for 16GB/32GB versions.
- flash it with Flashtool (http://forum.xda-developers.com/showthread.php?t=2785089)
- root using your favourite tool (I used one I had on my PC, not sure which version but PurpleDrake should do: http://forum.xda-developers.com/lg-g3/development/root-root-lg-g3-easily-purpledrake-lite-t2821000)
- find a TWRP image
- flash TWRP (I used this tutorial: http://www.phonearena.com/news/How-to-flash-a-custom-recovery-like-CWM-or-TWRP-on-Android_id53914)
- find the bumped version of 5.0 for your phone (mine is V20e-EUR-XX and I found it on this forum)
- flash it using TWRP
- start the phone and set it up (it should be rooted already)
- install the SuperSU binaries using TWRP
Fun and heavy Titanium Backup freezes ensue! My phone has now 80% battery left 8h after being disconnected from the charger this morning, as opposed to 60% after two hours just after installing the OTA update.
Note: this was done on the unlocked 16GB European D855 version I bought in the UK. Not sure about other versions!
Bonus: in order to improve my battery life, besides Titanium-Backup-freezing the hell of the LG bloatware (I think McAfee and LG Health are the main culprits) and some Google bloatware I don't use (Google Play Apps anyone?) I also disabled knock on by following the advice #8 in this tutorial: http://www.androidauthority.com/lg-g3-problems-517832/
I've read all about the problem with rooting the G3 Stock Lollipop Version.
But there is no info, where I can find out WHY it is how it is.
So, why is 5.0 actually unrootable? And will this change in future?

Ummm. Have you tried looking on XDA?
There was a BIG post with details. The technical part is here: link
No, this won't change. Restricting services to their context means that bug in almost any service won't be able to compromise entire system. That's a great security feature, actually.
Please bare with me as I am only 15 and know little to nothing about Android as I have been a Apple user my whole life. For Christmas my parents ordered me a used unlocked AT&T LG Optimus G Pro off of eBay and I am using it with NET10. I really, really want to upgrade it from Jelly bean to Kit Kat or whatever the new operating system is but every time I do it tells me I can't because it says ". I have downloaded the This device is suspected of rooting. Software update is not available for rooted device. app, Super SU which has the option to do a " Full Unroot". If I do this will this fix the problem and let me update my phone without locking it back to AT&T or bricking it? I am really worried about this, and locking my phone back to AT&T. When I first got the phone it would not even give me the option to update since the update comes from AT&T servers so I put an un-registered AT&T sim in my phone temporarily and every since it has gave me the option to update.
you dont need the official firmware to upgrade this, check out the android development section and look for the roms.
also there s a guide around in the general section, how to flash a rom and do some stuff like rooting, recovery flashing etc.
you should bear yourself to read as much as possible. it s easier than you think even if it looks dangerous and so on. if u re going to unroot your device, that s fine but think about other possibilities if u dont unroot the device
edit: i assume u re alrwady rooted and have a custom recovery inside. DO NOT UPGRADE WITH LG OFFICIAL FIRMWARES or you brick your device.

I consider myself pretty tech savvy and I cannot for the life of me figure out how to unroot my 10.1 2014 edition tablet. I cant even attempt to run the process to unroot because the download for the 4.3 frimware from multiple sites all linking to the same mirror wants to take 20 hours to download and I see no progress past .1 GB.
Things to note:
I do not need to save anything on my tablet, so if I lose data that is not an issue.
It runs on OS 4.3
it is the wifi only version SM-P600
It is from the united states (Its hard for me to find USA firmware, is it labeled something differently?)
I am only unrooting because I want to update to the newest frimware. I am assuming it will make my tablet smoother and conserve battery life.
I am using a windows computer.
Thank You, This has been stressing me out for weeks now and I hate asking for help but here I am.

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.

how to install LGUP tool
https://www.youtube.com/watch?v=igB5rnLRXSc&spfreload=10
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
I'm... asking for a friend....
But seriously, I tried following the instructions on the "[Guide] Step by Step from Stock N910V 6.0.1 to hsbadr's CyanogenMod 13.0 " thread, intending to bypass them when I got to the point of being able to jump over to the newer roms, and all I got was a boot loop when I tried flashing in 5.1.1. Is it because I'm on a retail 910v or was it a user error kinda thing? I tried multiple times and couldn't get it to boot after the flash, ended up flashing 6.0.1 back just to get my phone back.
I'm also ready to free the bootloader and root this thing. It seems emotion OS is the most popular and up to date now, correct?
I have the CPL1 update from Verizon( Dec patch). I know there are a bunch of threads with how tos, but it's unclear how outdated they are and whether it works with these latest versions. If someone can confirm the best way to go from cp1 to emotion.. Let me know.
Also.. I saw a while ago a guide on how to go to developer edition. Why isn't that front and center anymore? Isn't Dev edition completely unlocked... Why wouldn't I want to convert to dev edition before dealing with any rom changes? If someone can give some clarification I'd appreciate it.
Great news, I went for the plunge and succeeded. Confirmed -> stock and latest version software as of Jan 20 2017 (CPL1) can be downgraded to 5.1.1, rooted, TWRPed, and blah blah. I used the same guide you mentioned at top (hsbadr's CM13 guide), except i stopped at step 52 and continued to install emotion OS instead. Highly recommend it.
I'm on EmotionOS now. Wow, it was really worth it. So smooth compared to touchwiz 6.0.1. Haven't found a bug yet, but even if i do, i won't care.
I'm not sure what you mean "when i got to the point of installing newer roms". If you got to that point, why were you trying to flash 5.1.1 again?
How did you root it? I flashed mine back to 5.1.1, but I'm not having any luck rooting.

Follow the guide. You are going to go through a complicated process using the king root apk. I think the guide makes you use king root 3 times total to accomplish various parts of the process. King root loads up and spins for a few minutes, eventually succeeds, then you gotta punch in some things to command line using adb. I believe this is rooting your phone a few times.
Eventually you end up with twrp bootloader and jasmine Rom and everything just sticks.
So far.. The only annoying thing with emotion is that I lost volte and video calling. Maybe they'll bring it in one day.
