Unlock SIM - Lg ls991 - ZVC

[maxfloreshn]

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.

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.

you downgrade to ZVB and follow the instructions? or only download the global version of ZVB from the post and realize the process when the phone stay on ZVC?

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

Doesnt work for ZVD need help to unlock

Did you use LGUP to downgrade to earlier versions first? If I remember correctly, there might be a chance to use the ZVC tot file to revert from ZVD to ZVC?

zvd isnt rooted zv6 is the only rooted firmware and anything zvb and above cannot downgrade either
hardbrick can and will occur
a paid company or sprint is the only methods available unless root is found for zvb and greater

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
