[Q] Can't reroot - G3 Q&A, Help & Troubleshooting

Hi, so I while back I rooted my AT&T LG G3 (d850) and decided to unroot so I could get the lollipop update whenever that was going to be released. I completely reset it back to it's stock firmware and everything. After so many months of waiting for lollipop, I got fed up with it and decided I would try flashing a lollipop rom, but when I tried to root my phone with towel root and stump root, both of them said my device wasn't supported. Could anyone tell me why this might be? I was all ready to go, but for some reason I can't re-root even though it's basically a brand new phone.

You can't root lollipop as of yet. The only way to root is to downgrade to Kitkat.

Try purpledrake, that should work if you haven't taken any otas. If that doesn't work you will have to do as mentioned and flash previous software with the flashtool.

Thank you to everyone that helped! I figured out my problem. AT&T rolled out an OTA update which changed my build number from 10d to 10f. I just downgraded my firmware and was able to root. I'm successfully running CM12 now!

[Q] if i install new update on my vzw xplay will i lose root

hi i just rooted and installed a custom theme from uot theme kitchen and noticed there was an update (current installed version is 2.3.2) and was wondering if i accepted it, would i lose root, and more importantly would i mess up my phone because i have a custom theme?
Last time I checked the 2.3.3 Update is not available for VZW, unless you are talking about a different update. Please keep me posted as well.

well acording to my phone there is an update available (could be a new kernel) but shortly after recieving the notification for the 10th time i bought titanium backup pro (best 7 bucks ever spent on my phone by the way) i put "updateinstaller" in a bloat freezer and it hasn't bugged me since
so any idea if it'll mess up my phone?
If you update to 2.3.3 and your are rooted it will brick your phone for sure happened to me a couple days ago. If you want the update you would need to unroot and then get update and re root but I'm not worried about updating I'm a fan of my phone now so I won't be doing it any time soon maybe once ICS is out and there's a root method out.
unrooting or relocking

In what I have experienced, the phone bricks after unrooting and installing the update. I was wondering do I need to relock the bootloader. Unrooting alone still produces a paper weight.
Update: Locking the BL and updating worked. 2.3.3 working well unrooted. Seems the problem was with the flashtool.
I just updated and all I had to do was relock bootloader, it will wipe root by itself and when the update is done just unlock and reroot with same methods

[Q] How to Update Firmware After Root?

I am about to take the plunge and root the LG G3. It's been a couple weeks and I don't see any hardware faults so I would like to root and then debloat.
I can find some debloating threads here, but my main question was. . .how will I need to update after I have rooted the device
Say, I root today and then tomorrow AT&T releases an update for my device. Since I have rooted, I can't take the OTA update. But, is there a place that LG posts those updates? Can I download an update somewhere and and manually update with a specific windows application?
Or, will my updates only come in the form of ROMs after I have rooted?
I have the European D855 which was rooted using Towelroot. It has taken OTA updates perfectly twice now. Had to reinstall Xposed, but that was to be expected.

I'm not sure if it works the same way with the AT&T variant, but thanks for telling me your experience
It seems that some people reported being able to receive OTA despite being rooted, and some can't. I am one of those who can't. However, I have always been able to update using the LG PC Suite software even when I am rooted. That part I think is quite safe. Only issue is you will lose root after you've updated, in which case you will have to re-root. This may not be possible if the upgraded firmware has patched the exploit.

Most up to date unroot/root process?

I see there are several methods our there for unrooting and rooting the lg g3 but I noticed that they say only for lollipop or for kitkatt and lollipop. Does this matter if I'm currently on 6.0? Want to be sure before I do something critical and then regret it. What is the most up to date process you guys are using? I want to unroot and default back to the stock g3 rom to then reroot my device and flash a 6.0 custom rom completely fresh.
I used to use the following method but it started giving me issues. I then found out that it was because it was outdated.

LG G3 VS985 Root Help.

I have an Unlocked LG G3 VS985. I have been successful rooting it, but then I restart the phone and it does not stay rooted. It's running Android M 6.0
Software version: VS98547A
Someone please help me out.
http://rootmygalaxy.net/how-to-root-verizon-lg-g3-on-marshmallow-47a-firmware/
I flashed to 47A and lost root also (from 46A). I read perhaps going all the way back to 10b and then going to 47A from there may keep root. So I tried doing this today (link above) - but instead of flashing what the author recommended, i flashed another rom (aospa 6.0.1); i had root until flashing the rom, but couldn't find a way to keep it, again.
It may work if you flash the stock 47A rom the author provides. I'm not gonna try it again, though. I'll wait until there's stump root like apk that can do it for 47A.

Is a downgrade from fully stock MM possible?

My mom accidentally upgraded her Note to Marshmallow. She hates stock because of how slow it runs. I've had @hsbadr's CM on my Note for a while now and I really like it. She's willing to try it out, but now that she's upgraded to MM, there's no root.
Is it possible to flash the full Stock 5.1.1 tar, or do I have to wait for KingRoot? I remember someone saying, in one of the threads I'm subscribed to, that it could be downgraded, but I want to make sure, since this time it isn't my phone. I would try it myself and maybe soft brick my phone, but mine is already happily running CM.
The phone should be on the CPF3 firmware right now.
Sorry to bump this, but it would be really great to have a definitive answer. Everything's backed up, but I still don't want to hard brick the phone.
OK, so I went ahead and tried flashing the StockRestore BPA1 firmware. That led to this error: [tz] fused 2 > Binary 1. Apparently I can't downgrade the bootloader, and that's why I got that error. I'm now trying to flash the N910VVRU2BPA1_N910VVRU2BPA1_VZW firmware.
That one worked. I was able to boot into 5.1.1, but since it still had the 6.0.1 bootloader (I think this is the reason), KingRoot wouldn't work. Using the Kingo Root desktop app (it's been updated; looks a lot nicer) allowed me to root and unlock.
