Are you sure you can downgrade to zvb? I head you can't!
If you did it , how it was? You just flash it by ToT?
I've just downgraded from ZVC to ZVB by LGUP, it's OK!

So I can flash this rom on a completely stock LS991 on ZVB unrooted? How do I do that? I looked at the source page and could not see flash instructions.

Wow, there it is. Thanks for this info. I am going to try this. Do you know if any version of the rom allows to customize APN settings ? I have a sim that requires me to custom set the GSM APN settings.
AFAIK ZVB stock I could not edit APN settings even with MSL code.
Thanks

Use the global version of this ROM, it has apnconfig.xml from global G4 and there is a great chance you'll have the right apn, anyway you'll be able to create your own ones!
Maybe you'll need to type ##3282# in the dialer, go to the apns menu & reset settings to default

Hey guys,
First off, i thought I had already posted this question but I can not even find it in my ousting of posts. So I want to apologize I advance of this ends up as a duplicate.
I currently have a Sprint LG4 that upgraded to ZVA and I lost hotspot. Trying any method to downgrade, fails. Using LGUP fails with "SPC code does not match." and LG Flash Tool says error at DoDownload and nothing other than a code, 00000064. I have also tried the method using systemZV6.img and dd via SendCommand but nothing happens at all with that one after i press Enter and wait a few his.
I have tried various USB ports and all drivers I could find on these forums. Windows 7. Any other info I can provide to help you help me? I am no stranger to flashing other phones, but having no luck here. Searching the web hasn't turned up any help. Thanks in advance.
Is the phone bricked now? You can't downgrade from ZVA to ZV6, because the qfuse version is different.
Thanks apparently i missed that one somewhere as a search via duck duck go never gave turned up results that stated so. In fact the last posts of http://forum.xda-developers.com/sprint-g4/general/how-to-free-mobile-hotspot-root-t3165049/page16 led me to believe it was possible.
Fortunately it is not bricked. Thanks for your reply.

Since it is not bricked, you could probably fix it by flashing the ZV9 update. I don't think there is a tot for ZVA yet, so you might possibly have to wait until there is one available.

if mine is ZVA, can I use the path ZVA -> ZV9 -> ZV6 to downgrade to ZV6? I mean using LGUP.

I don't think you can even use ZV9. I know I said you probably could, but I forgot that's the whole reason you're here; because the qfuse version is different. You will have to wait until a ZVA TOT is available.
I could be wrong, but I'm not a dev. At least be thankful your phone isn't completely bricked.
I just downgrade from ZVA to ZV6 using LGUP. Just the first boot take more time than usual but I did factory reset and everything fine.
qfuse is not different. It should work fine.

Having issues as well. ZVA>ZV6. When I dl the tot file and run it in LG up it says it's not a valid tot file. Also tried the LG flash tool method and get an error message. Any help?

Anyone try to update back to ZVA after root?
Once rooted you can't use the OTA updates because they will fail. They check for that kind of crap. Sucks, but you're stuck on ZV6 with root until the devs work out a bootloader unlock, which may take some serious time. LG sucks major donkey balls because they have some pretty secure bootloaders, now. The best thing you can do is stick with ZV6 at the moment. I know, I know, security patches! Marshmallow! Still, wait until they get something worked out.
Thanks, i figured. Only reason i ask is because im having an issue with mircast. Not sure if its because im on ZV6 or because im on UltraPop..
So we downgrade zva to zv6 or not

Hi,
I have recently purchased a LG G4 LS991 and tried to find its rooting method but was unsuccessful so please if someone could point me in the right direction if the root is possible or downgrading is an only option.
Here are some useful details of my G4:
Android version 6.0
Kernel 3.10.84
Build MRA58K
Software version LS991ZVA
P.s I apologize, if this has been asked before.

I want to share my experience with you guys.
So I've updated my LG G4 to ZVC firmeware, and read that is not possible to root it, and no unlock chances therefore. And since is really difficult to make downgrade once you've reached this version, I was totally freaked out that I wouldn't be able to unlock it.
And thanks to some brave community fellows that tried this method, I felt encouraged to do it.
In order to unlock your network, you have use a Global rom for ZVB firmeware, YES, it also works for ZVC. Said that, I have to tell you that this it's a risky method, and if you don't properly follow steps, you'll hard brick your phone, so do it at your own risk.
Here is the link:
http://forum.xda-developers.com/spr...-mellowmallow-debloated-60fps-camera-t3358340
Please, make sure to thank the OP and developers. Buy 'em a beer or something
Going from ZVC firmware, did you have to deviate at all from the instructions at that link you provided? Or did you get success following it exactly as written? I think you convinced me to take the plunge.
(Well, also to be fully honest, now that the V20 is available, I'm more willing to take risks with my beloved LG G4 in the secret hope I might break it and justify the expensive upgrade as being forced into it)

Hi, just go to the link and follow the instructions there, you'll be alright.
I made this threat since everyone was confused about this firmeware version, and I wanted to share with you that YOU CAN UNLOCK the network once you are in ZVC as I DID. So no worries, you'll be able to unlock the sim from your LG G4 ZVC, using the ZVB procedure.

In this particular case, just Install the ZVB Global rom (Even if you have ZVC like me). No downgrade needed. Once you've installed the ZVB Global rom (FOLLOWING THE ALL THE STEPS of the original post) you'll have your phone UNLOCKED and running ZVB.
In other words, it is not a downgrade process (Although you'll be downgrading your phone from ZVC to ZVB) NO ADDITIONAL STEPS for it, do like your device was on ZVB and please, don't skip any step and you'll be fine.
It worked for me, it will work for you. Good luck

ive never dont the method but can descibe it to a T
on marshmallow sprint closed the send command port on g4 so a very dangerous technique in opening it as follows kinda. you open lgup and flash some tot dont know which one but as soon as it hits 9% this is when the send command port gets opened You have to unplug the usb cable exactly rite time and the send port stays open then u can dd in the system image.
now it is dangerous can hard brick device but im digging up the links now
I've been searching the forum for a while, but most of the rooting guide are based on earlier version. Do i need to downgrade before rooting?

Yes you would need to downgrade, but since you have a T-Mobile version it's most likely not possible due to anti rollback

yes, same thread, just do the steps about OEM Unlocking and Root. i would grab the most recent twrp image from here (3.1.1-1) and the latest SuperSU here (2.82 TWRP Installable Zip)
you will also need adb and fastboot tools on your pc, get that here, latest version is 1.4.3
or you can just flash twrp and then flash an already rooted system image for 20v from @MicroMod777 found here
