Rooting ZVC - Sprint LG G4

I have been out of the loop on this phone for a while. I had to get a replacement G4 and it came with ZVB and I recently took the new ZVC OTA. It looks to me that there is no current root method for phones running ZVB and above. Can someone please confirm this for me? Just wanting to make sure I am not missing something.

Root has been gone for a while with a locked bootloader it's very highly unlikely new software updates will never receive root. At least on older phone models.:crying:

Zv6 is only firmware rootable.
as of rite now you cannot rollback before zvb any ways. You can brick device. Basicly for now ypur screwed til someone makes a modded sysyem image with tweaks only no root. U aint missed much on g4

I have also just now come back to the G4, and it seems like there is no root method at all, even in mods like my favorite UltraPOP AOSP, the difficult ones where you're pulling the plug on the battery at certain times.
What those mods HAVE done, specifically UltraPOP, is that they are able to unlock or make accessible most things people want root for, but manually, and requiring a software update for each thing. Those may do what you're looking for.

OTA 139.15.1 keep root

All,
Has anyone on Verizon done the OTA update and kept root? From what I've been reading, sounds like if you rooted with MotoRoot then you're okay, but not if you used PwnMyMoto.
As far as people getting a bootloop, that does make some sense because the recovery partition is really just the boot image... So I can flash the stock recovery to the recovery partition before running the update, and that should theoretically prevent a bootloop. However, if this is going to erase my root, then I don't want to do the update.
So, has anyone on verizon done the OTA and kept their root? How did you do it?
First item, this is a question so it should belong in the question and answer threads! Secondly look here http://forum.xda-developers.com/showthread.php?t=2466191

Sorry, and thanks! I'll probably give this a shot, make that camera work a little better...
You can always install the SafeStrap ROM here. That's what I did.

[Rom] [VZW] SafeStrap 139.12.57
Sent from my Moto X
The way that everyone (including myself) have been updating and keeping root on Verizon is as followed:
1. RSD back to stock (instructions here: http://forum.xda-developers.com/showthread.php?t=2446515)
2. Install PwnMyMoto and DO NOT RUN IT
3. Download and install OTA
4. When the install completes, your phone will reboot a few times. This is just PwnMyMoto doing its magic.
5. Profit.

This method makes it so SafeStrap is no longer available though, right? If that's not the case then... Don't know what I've been waiting for!

I searched around and can't really find an answer to that. I don't use SafeStrap so I have no idea. I'd assume you can try the method I posted and try using SafeStrap after. If that doesn't work then just RSD back to pre-update and hang on to SafeStrap until it's figured out. No guarantees if it'd work / break stuff, though. You'd be the guinea pig for that one.

@jcase Any chance you can answer this for us? Just cause someone was able to keep root (the one shot kind you mentioned), does that mean that using RSD is still on the table?

If you take the OTA you dont have wY to revert to old stock Motorola block the reverts already and @jcase already said that he will be back for root in this device till 4.3 is out

I think that's not up for debate. The issue is that even though you kept root, you're now blocked from using safestrap or ever gaining root again in the future (once another ota comes through). The update has now patched root going forward and it sounds like you won't be able to keep it after this update.

Safestrap i know about and dont care about as i dont use it. As for moving forward with root I'll be surprised if that is the case but I wont disagree either. It is very possible they patch something to actually block root down the road. From my understanding tho currently the patch is blocking ppl to root the update not keeping root if the process is followed correctly. My guess is odds are it will be the same on the next OTA just like we had to do on the original Razr line to keep root until the bootloader was unlocked. However if the next OTA is 4.3 tha tcould all change for sure as anything is possible. Even so when that time comes I'll just unlock mine. I do have a Dev edition i just haven't unlocked with it being brand new and not wanting to void warranty yet to make sure hardware is cool but i do want root so i went the long route for now is all.

So I installed PwnMyMoto, SuperSU and OTA Root Keeper, then decided not to root. I installed the Verizon update and boom, I'm rooted. Is that what you're saying is needed? I was surprised that root apps all work fine for me, I really didn't do anything but install those apks before I installed the camera update!

As long as you had PwnMyMoto and never ran it / not rooted you were good to go. SuperSU could be installed before or after. I dont think OTA Root Keeper was needed at all. PwnMyMoto runs after a reboot so once you installed the OTA and rebooted it did its rooting magic automatically for you. Glad it all worked out for you

That's awesome, didn't realize that would happen automatically. I completely expected that I'd have to complete the entire root process steps that were outlined in an earlier post if I wanted root. Thanks for the reply.

people who have moto employee friends say they are moving to 4.3 next. Also, there may be a work around for you to keep root with the next release, but because people who aren't on dev phones that must be sure they can retain root would not have used this method (as it is a one chance type of method). so it is more likely that any new workarounds that people come up with will be for those that still have the ability to downgrade to original stock firmware. Also, SS is nice because it gives you the ability to run the phone just like you normally would but you can create complete backups of the device so you don't have to set everything up all over again if you screw something up with your phone. Even if you don't use SS for flashing roms it is still useful for back ups.

I have my Moto contacts and yes they are moving to 4.3 next last i was told when I asked. As for downgrading stock software that isn't going to happen once updated as you can't go backwards. Moto devices have been that way going back to the original Droid Razr. Its few and far between where you could actually go backwards after an OTA. So unless you mean stock of the current build installed then ppl will have issues for sure. That said if ppl OTA and have root now but for whatever reason need to use the new fastboot file that was just posted they will in fact be SOL for gaining root. This is exactly why I refuse to buy consumer units from the carrier besides a few other reason I wont go into. My theory is simple we want to mess with device buy an unlockable one or be ready to suffer/wait for an exploit after an OTA hits.
As far as root moving forward what process you talking about tho? There is 2 ways to do it. The one posted right above your post in this thread, or the link I posted above. If the info in this thread was used yes there may be an issue because of the patch. However I will be very surprised to see ppl not be able to keep root if they updated using the process in the link I posted above. Besides having to fastboot the boot.img to recovery in that process its the same way original Droid Razr owners had to update to be able to keep root if there was no root process for the OTA being pushed. Moving forward my guess is there will be an issue once 4.3 hits tho. I'm not sure you will be able to use the old kernel from 4.2.2 to overwrite recovery and boot the 4.3 /system so you can restore root and pull the actual 4.3 boot.img so that can be used for the recovery highjack. Bottom line is only time will tell at this point as you never know what Moto/Google will do with the next update.
Agreed on SS for backups even if not flashing ROMs, but personally i just dont mess with my device enough to worry about a full back i guess. For apps/settings I just use MyBackup PRO. I've also have an app a buddy made that creates a full XML if i wanted to use it. In the old days I use to make alot of backups for ROM flashing when I used SS. Guess in my old age I've just got lazy and dont worry about it that much anymore. I really hose the device I'll just swap to one of my others til i get back to fixing the messed up one.

3 ways to maintain root are the one in the thread, SS, and the one you posted. The one you posted actually allows you to flash the original stock firmware on the phone because the BL was never touched thus the security (keeping you from downgrading) was never installed. That was what I was referring to when I said those that must make sure they will retain root in the future would not have done the install pwnmymmoto without running then take ota then run pwnmymoto. As you said those people will be screwed if the next root requires you to flash back to original stock or use part of the pwnmymoto exploit that will only be accessible to those that got the OTA with SS or the link you posted. I don't toy with my phone as much as I used to especially this one, but bypasing exchange security is pretty essential for me. I don't want an encrypted device with mandatory pin. I never lose my phone and I would know within minutes of losing it if i ever did so I could shut it down remotely.
And I'm not sure about the new kernel situation either. This is why I wanted to make sure I could go back to original firmware as I see that being our best bet to retain root through 4.3, assuming jcase doesn't release another exploit for it to get some cash.

Gotchya, makes total sense now what you are saying. I think there is just confusion at times when talking about root & OTA because of different ways to do it in a case like this device. Being a Moto guy for so long tho i'm use to all the BS they throw at us.....lol. That said that is why i posted the link I did. Imho it's a bad plan to update using the other method of installing pwnmymoto and not running it first before taking the OTA. Doing the process to protect root before updating is a much safer bet atm imo. Sure its a little more work but at the end of the day you dont have to be worried as much moving forward. Only concern I have still for doing it the longer way is if that process will work when they push out 4.3. It had alot of changes in it so lord only knows what will be up for keeping root. And really in my case its no concern but for all the folks with consumer version it is still a concern i think for the time being

A little guidance please

I have had my G2 for about a year. I had rooted it and never took an update after 11A. I was happy with the way my phone worked and read some of the stories where people were not happy with KitKat.
Unfortunately, the touch went out on my screen and I had to get a replacement. I successfully flashed my old one back to stock and removed root w/out a problem.
Now my problem is this:
The new phone came with 25B. I understand there is no way to root this version. The phone is already wanting me to update to 26A. What I would like to do is rollback someway, root, then take updates. I can already see my phone signal is not as strong as it used to be.
My questions are:
1. Can I rollback to an earlier version and root via one of the IORoot options? (TOT it like I did my old phone)
2. What version would I need to rollback to to accomplish this.
3. Could someone point to the correct thread to do this?
4. Finally, I see it seems to be ok to take factory updates if you are rooted only. I am not interested in custom roms. I use Titanium Backup to freeze bloatware and would like like to be able to use it again. I have quite a bit I need to restore.
I have done some searching but it seems the G2 section has changed a lot since I was last here. I do appreciate any help and/or pitfalls you can warn me about. I do have the LG Flash Tool 1.8 installed and am familiar with how to install the needed TOT file.
Thanks....

You can kdz or tot back and root from there. Root sticks through 25b but not 26a update.
Thank you. I will go ahead and update to the 25b then.

Stock / Rooted?

I may get an LG G4 and have a couple of quick questions.
Can I just run the phone as stock/rooted? What's the latest official Android version? What's the current easiest root method? If I get a new phone that I want to run stock/rooted, do I just accept all updates and then root when I get to the latest version? Any systemless root option?
With root, can I still take OTAs and then (hopefully) re-root after or once the update installs or will the rooted phone not take OTAs and then I'm forever on the path of having to manually flash updates?
Yes you can run the phone stock rooted and still take updates. But if you do take any updates you take a chance at either losing root or bricking your phone (Someone with more experience would have to answer that but thats my guess) The current version is 5.1 (6.0 for international and sprint). So far this is the easiest root method http://forum.xda-developers.com/showthread.php?t=3191038 (only for h811 with 10n base) after you do this root method be sure to download twrp and install it with flashify. If you're running 10h base use one click twrp. So far there is no systemless root for 5.1 (only for 6.0) that's about all i got for you.
I saw where the thread to return to "stock" was removed due to a brick issue.
I have the T-Mo G4, running H81110n, and I'd like to un-root it so that I can trade it in back to T-Mo for something new. What's the easiest way to do that, without triggering alarms? The G4 is still new enough that trading it in is worth it, rather than just tossing it in a drawer with all my other old phones.
I used the "low effort" root from jcase/autoprime/tylerfixer back in July. Other than flashing the upgrade to H1110n, I haven't done anything crazy with it.
Thanks!

Going back to LP 10N from MM 20i

I have seen this question asked but have not see a definate answer. Is it safe to go back to LP 10N after upgrading to MM 20i?
Have anyone successfully done this and how did you do it? I have seen conflicting info on here, some say yes and some say you will brick.
Why go back? First I have had issues with bluetooth and wifi, also my Wifi Tether Router app will not work since upgrading. I seem to have had better battery life also on LP.
Thanks
You can, I read someone flashed the wrong KDZ file (10N) instead of MM (20i) by accident after going to MM. His phone was alright its been confirmed but never hurts to double check.

Well, there's this: [PSA] **WARNING** DO NOT TRY TO DOWNGRADE YOUR G4 BOOTSTACK (in USA at least) - http://is.gd/UbYGLN
And this, from Hyleton who is an expert on restoring stock to LG phones: Currently with T-Mobile/H811 You can no longer downgrade past the current kdz as of 9-19-15
I'd be *very* careful about relying on something reported anecdotally, but I'd like to know because I've hard bricked LG phones in the past due to bootloader conflicts and I'm not anxious to repeat the experience. Right now the G4 I'm expecting soon is on 5.1 and I"m inclined to keep it there if I can't downgrade.

If you are in 20i you can safely downgrade to 10n, problem was downgrading from 10n to a lower LP kdz.

I am on H81120i, rooted and have a couple of questions about reverting back to LP.
1. Were you rooted on MM?
2. Would you be willing to provide the method you used?
Thank you

The only way to root and install twrp is from the following thread
http://forum.xda-developers.com/tmobile-g4/development/stock-h811-20i-images-kdz-flashable-t3308227
Or this post here..

P.S. @kennethrkennedy
If you did OTA or flashed the 20i kdz on top of 10n i recommend doing a factory reset, i know is painful cuz needbto reinstall everything again but that may fix a lot of issues including battery life.

DrakenFX, thank you for responding! I just want to make sure we are on the same page. I am currently on MM and have rooted with the 2nd method you listed. I am having a lot of problems such as 5mhz wifi disconnects, very bad lag in all apps & Chrome scrolling so I want to downgrade to LP. (FYI I did factory reset several times after the update).
Since I have an unlocked bootloader I am not sure of the process to revert without bricking my phone. I have searched google and the forums and only a couple of people mention successfully downgrading but don't list the method.

Seems like experience may very but in my case I'll never going back to LP , MM is been awesome so far no lags battery been great and performance been increase.
Method they have use is using LG UP Tool + 10n KDZ, you will find those tools in @autoprime 20i update thread.

I could not get that method to work - kept getting an error. I was successful using this: http://forum.xda-developers.com/tmobile-g4/development/rom-g4-h811-10n-stock-restore-t3191756
I booted into twrp - wiped everything then flashed both zips and factory reset. I'm in love with my phone again :victory:

Well, there's this: [PSA] **WARNING** DO NOT TRY TO DOWNGRADE YOUR G4 BOOTSTACK (in USA at least) - http://is.gd/UbYGLN
And this, from Hyleton who is an expert on restoring stock to LG phones: Currently with T-Mobile/H811 You can no longer downgrade past the current kdz as of 9-19-15
I'd be *very* careful about relying on something reported anecdotally, but I'd like to know because I've hard bricked LG phones in the past due to bootloader conflicts and I'm not anxious to repeat the experience. Right now the G4 I'm expecting soon is on 5.1 and I"m inclined to keep it there if I can't downgrade.

This is a bit late to comment, but I updated my thread's first post to say specifically that downgrading to 10N from MM is okay. Autoprime updated his thread to state it was okay specifically also.
The anti-rollback flag is v2 on both 10N and MM, so LG won't destroy your phone by going back to 10N.
Currently mine has 6.0 and the performance is a bit better.
Battery is OK but your mileage may vary.
Simple TV or Tablo users: 6.0 fixed wierd video rendering problem.
can i downgrade if im on stock MM from lg bridge not rooted?

rooted LS991ZV6 and OTA

was wondering, if im rooted on v6 (5.1) and looking to ota to marshmallow (6.0) can i ota without error? since sprint came out with ZLTE its in the update from what i understand. friend got replacement yesterday of same phone. seems to be quicker and better signal. or anyone recommend a 6.0 rom?
i do plan on doing the wifi teather before updating. is that trick still working?
second, if not worth it how easy to downgrade again? last time i rooted it was very different than just using odin or a single app. has the rooting method changed at all? i was able to upgrade and then downgrade again, but was very uncomfortable doing it, and i have flashed a few phones in my day.
thanX in advance.

Unless something has changed u cannot update no root available after zv6. And if u get to zvb i believe u cannot downgrade. Ive hd mine on zv6 since day on and will not upgrade. Roots the only thing keeping me from getting rid of this thing
Ive seen a few posts about downgrading from marsh back to lolipop. Unless i was reading it wrong.
But having no root isnt my cup of tea either. Seeing alot about root and the H815.
