New Verizon updated being pushed VS99513A - LG V20 Guides, News, & Discussion

just received a new update notification to VS99513A so if you are planing to root , I would hold off taking update until confirmed that the exploit will still work. Just a heads up

We do need to know if this breaks the exploit..... I don't want to accidentally install this update and dash the hopes of root/unlock

and when you rooted your phone did the 2nd bootup after starting step3 before the adb reboot recovery command take a really long time or stay in the verizon logo. If so how did you fix it

So I can do boot2 even before I flash SuperSU?

Does this update prevent you from KDZ'ing back to 11A using Uppercut + LG UP?
If not, then in theory, if you were to purchase or replace your V20 that had 13A pre-installed then you could KDZ back to 11A and then use dirtysanta from there.

I don't think it's possible for it to stop the uppercut restore method unless you manage to delete your bootloader or something like that

It is possible. If 13A has ARB enabled then you will be unable to install 11A KDZ. Since this update most likely breaks dirtycow then I would not be even remotely surprised if they have ARB enabled.(ARB is AntiRollBack)

I don't think ARB is enabled because I was able to flash 11A after the 13A update when I wanted to reattempt root

Since I needed MobileIron for work, I can never root or unlock bootloader. It's actually kind of relaxing. You just use the phone and let it be. Nothing I really miss.

Anyone try to downgrade from 13a yet in order to root?

Yes. possible.

You don't need to downgrade to root. If you're on 13a you can still do the exploit successfully.

@me2151 is this true? Or do we need to downgrade?

You can try to root on 13A but there have been reports of it not working. It is downgradable to 12A and rootable for a fact though

With the update coming sometime in the near future, what does that mean for us with rooted phones? More specifically, us losers who are on the Puerto Rican rom.
I imagine if we update we lose root, but is there any way we can get back on the American AT&T H810 after the update comes out?
I just got the phone from Craig's list. When I got home and I did more research I realized I got screwed. They sold me the PR version of the phone. At least I got it for 280 unlocked and no scratches almost new.

Yikes sorry! Do you have the green spot issue in the camera? It's a decent rom save for that issue. Allows you to get rid of everything (bloatware). I've been dying to add xposed, but without being able to back anything up makes it a little iffy. AT&T seems to be the worst when it comes to allowing their devices to be unlocked.

If LG releases a KDZ for ATT you can. However, even those of us who are on att firmware can't take OTA updates after rooting (even if flashing an unrooted system img). LGs root checker tool flags the system on the /persist partition
This means that you will have to UN-Root your phone. Download & install the update. Put your phone into download mode. DD if=OS of=Backup.img
Then root that backup (Or get it from someone who posted it on an XDA Root site)
Once it is rooted, then DD if=RootedOS of=OS (Disk dump it back to the phone)
Now you have a rooted Marshmellow OS on your phone.

this is false. i was rooted on 10g, i unrooted and flashed stock system.img and took the update to 10o just fine.
you need to do a few things to prepare first
1) unfreeze any apps you may have frozen with debloater/titanium/greenify/etc
2) disable and uninstall any xposed modules
3) uninstall xposed (if you have it)
4) uninstall flashfire (if you have it)
5) uninstall any root apps (aside from supersu)
6) open supersu, uncheck "enable superuser" and then select full unroot, than reboot
7) download and flash the stock system.img for whatever firmware you are currently rooted on
8) now your unrooted and you may update via ota
this thread will help for flashing, just make sure you use the stock version of your current firmware: http://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586

I completed those steps, however right at 4% still getting error 0x1123004.
I re-rooted just to make sure everything was unfrozen etc, uninstalled everything, then flashed unrooted image back, still giving the error.
Guess i'll have to wait for another method.

I don't think we will ever see that fixed the right way. I'm 99% convinced it's a hardware issue.
My update is running now. Agree the update is pretty big. If this fixes battery drain, no need for root for me.... Between package disabler pro + runtime permissions, not much is needed anymore for root. The only thing is some are saying if you use package disabler pro, there can be more battery issues than not because the OS tries to reference those disabled packages. I'm not sure how that would be any different though if you froze them with titanium backup or something

I installed the update. My phone rebooted and after I log in it goes to a black screen that says "Installing applications" with a progress bar that never shows any progress. Not sure what is going on and how to get back to my launcher. When I select the recent apps button I can see my recent apps and interact with them. It is just the launcher and pull down notification shade that are not running so I can't launch anything else.
Any ideas how to fix it?

The last paragraph says it all. If someone is working on an exploit to unlock the bootloader in it's current state, and you take the update, * After updating , you will not be able to downgrade to the old software because of updates to the security policy. * Then you would need to wait for the next exploit to come out to get past the new security updates.
Whatever, the phone is great stock with package disabler. Only thing I might want root for is unlimited tethering.

Help, H950 flash to stock for OTA Update?

EDIT: Looks like its not MM but some security update, so that sucks but I'd still like to know if anyone successfully got back to stock from rooted 5.1.1
Hi everyone.
I'm trying to find a way to restore my H950 to stock and completely remove any trace of root so that I can install an OTA update. I have tried installing the update with LG PC Suite and LGMobile Support Tool. Both of them say that I am on the latest software (5.1.1 H950v11?). It has been so long since I rooted it that I can't remember what method I used. If anyone has any idea how to flash it back to stock, I'd appreciate the help!
More Details:
I have an H950 (US AT&T) rooted on 5.1.1 and I just started getting an update yesterday saying that I have a system update available. When I tried to download and update, the phone I got an error while the update was still at 0%. When the phone restarted I got the "This phone is suspected in rooting..." Error.
I have tried following this thread [Guide] LG G Flex 2 Stock Firmware (Go Back to Stock) KDZ & TOT Method
but it didn't work. I got the flash utility to run but I still had SuperSU after it flashed my phone and the update still failed due to "Suspect in rooting."
I also tried following this thread [Tool] Easy Restore/Unroot Tool for LG G Flex 2 [09/15/15]!!
but I could not get it to work. The utility just hangs at "Working..."
Anyone successfully used either of these methods on an H950 with 5.1.1 to get back to stock?
Thanks in advance!

It's entirely possible that I am technologically inept, but I am having the exact same issue as the OP. I followed your guide (which was very helpful) for the TOT method, and there is no option to use CSE flash, or at least it's not discussed in the instructions.
I flashed my phone twice using your TOT guide -- pretty sure I followed it to the letter. It completed successfully, but when the phone rebooted, I still had root access. I'm not sure how to unroot this thing so I can receive OTA updates (and maybe sell later on down the road).
Thanks for the help!

Umm, so I found a possible solution on another thread in this forum. Maybe the answer was so simple that nobody thought to mention it. But apparently, you can just remove root access within the SuperUser app; just select "Full Unroot" or "Total Unroot" from settings. Then run this TOT flash, and you should be GTG. I am trying this now and will report as to whether I am successful.

Rooted or not you should be able to go back to stock. And CSE flash is for the kdz method of lg flash tool. Which I didn't realize what model they were needing help with. Also with the H950 LGUP should be used instead of normal flash tool to avoid any issues with the flash tool.

Hmm. Thanks for helping us out. So I am kind of confused. I reinstalled the Tot file using LGUP, and it completed successfully. I selected "REFURB" mode, and it completed successfully. But after it finished, my phone is still rooted. (I verified with root checker.) I just want to go back to stock so I can get OTA updates (and MM hopefully, when/if AT&T releases it). Now my phone won't get OTA updates because it says it's "suspected of rooting." I bought the phone used off of Swappa, so I'm not sure how exactly the original owner rooted it.

At this point you'd be better off waiting for a KDZ of MM when it comes out for the H950. (But remember, root will probably never be achieved for our devices on MM, if that's something you care about).
I remember buying TWO H950s. Both needed the OTA for the latest Lollipop. But despite several hours, several methods, and several hours at the ATT store, I was never able to get OTAs working on either of them. It was impossible.
And supposedly impossible for several other users on XDA, who couldn't get OTAs working for their ATT Flex 2's. So even if you manage to unroot, don't get your hopes high believing OTAs will work.
Did somebody ever able to go back to stock (H950) from rooted 5.1.1? Where did you get the TOT file?

Just for grins I tried to do some adb commands on mine, after adb reboot, I got the android with a red triangle and from that point couldn't issue adb commands..

I have both the h901 and h900. I updated my 901 to Nougat, and in the same thread the Dev says it is possible to use on the 900. Anyone tried this or willing to try?? My wife uses the h900, sooooo, if I screw that up I'm sleeping on the couch..

My ATT H900 is still on lollipop and is rooted. Do you think this would work on my phone and if so, what steps do you think I should follow?

I can't really say. My H900 was rooted and on LP, but I upgraded it back in January. Now when I try to do anything with ADB, nothing works and my PC doesn't even recognize it. My plan was to follow the Dev's directions, only pushing system.img and boot.img.
I may try again later
Waiting for good news... ?

You may want to send a message to the Dev over in the H901 section. Here is what he told me just today. Sounds like you are at the right point according to him.

Hi
I tried to use it, but I am unable to boot into any recovery and if I try "and reboot boot loader" the h900 just reboots back into MM.
I am currently on H90021w.

everyone one be very careful, something went wrong and i lost TWRP. Had to fully upgrade the phone to 10p to get it going again
Hopefully someone will come out with a root for 10p

what did you flash because I flashed the kdz and went to stock 10p which you cant root as of yet one thing you could do it flash 10j kdz and then reroot your phone though not sure if all you data will be there but thats your best chance.

I wouldn't tell ppl to try and down grade to another lower kdz because it will brick their devices. Please don't tell ppl to do things that will cause them to brick their phones.

First of no need to be rude and second I asked him what he flashed because if he was still on 10j he could reflash and start all over and if you try to downgrade from 10p to 10j it would not brick your device because it wont flash because of the rollback version change and I have tried on my person device to confirm so before you put out accusations I would do my research and I never told him to flash it I told him he could try and either way if he flashed a 10p rom and has no os he would be forced to flash the 10p kdz to fix the issue because the 10j would not work and I have tested the kdz on my own device and works flawlessly so.... I am not telling anyone to brick their devices I have tested all of this before I even responded and then again it is your own responsibility and your own device you do what you want just because someone said something doesn't mean you have to follow it. All I did was give him a suggestion and it was on him to do what he wanted to his device from there.
ps. I have downgraded for 10k to 10j many times already and never bricked my device so do a bit of research before saying anything

Seriously I didn't think anything I said to you there was being rude. He said he tried upgrading to the 10p and it failed and he lost root and had to continue upgrading and finishing it without root. Then you told him to try to downgrade and he can't do that because he will brick his device I was just trying to give him advice not to try what you told him to try only because he was on 10p. Man ppl are touchy these days about everything.

sorry bro didn't mean to get on you like that I see where your coming from but you accused me of telling people of wrong information causing people to brick there device which is incorrect if you try to downgrade it wont brick your device it simply wont flash I have tried it a couple of times. I didnt see the part where he was already on 10p and I have flash 10p and tried going to 10j again but it wont let you and it wont brick your devices even if you tried it and then again sorry if I offended you in any way
