Is it really possible to flash a custom ROM on a nexus one with only root and without unlocking the boot loader? I was under the impression that it is impossible but the nexus one wiki states you can either unlock and root or root without unlocking and flash a custom ROM. Would this work with CM7? Thanks and sorry for being a noob but I couldn't find a clear answer to this.
Yes you can, I'm on CM7.
Thanks so much, also does anyone know if there are any special steps involved getting there if you have a nexus one with a slcd panel. Steps for getting back to stock would also be awesome! Thanks!
EDIT: Just to verify, custom recoveries are overwritten by the passimg method of getting to stock correct?
Root and passimg are the same for slcd and amoled panel there are no special steps. Passimg will not revert you back to stock recovery but it will return the stock ROM which upon boot reverts the recovery back to stock.
Thanks for all the answers. I've put together a little guide for what to download etc etc... I think I'll bundle everything and upload it with instructions at some point. Please do tell me if there is a complete guide to flash a custom rom without unlocking that is not as confusing as the wiki for noobs. Also I believe my guide would alleviate some slcd bricking...
Look for a thread sometime in the coming days...
My LG-G4 is rooted and has no custom rom or anything like that.
LGH-811
I want to know if I'm able to unroot this safely without bricking it, im stuck on 10h but can I go to 10n?
I read autoprime warning but I was still pretty confused, so I'm not sure if I'm stuck with this root or if i can unroot safely.
If I can, please tell me what to do.

Follow the instructions in this link to install 10N if you're on 10H.

You CANNOT Downgrade from 10N back to to 10H (BRICK), but you CAN install 10N if you're on 10H.
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.

Can you give more detail? I have used the TOT and instructions from http://forum.xda-developers.com/sprint-g4/development/restore-sprint-lg-ls991-zv6-tot-t3213196 and always get an SPC does not match error.
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
Can anyone successfully downgraded to zv6 if YeS so how

Yes you can, I did it myself. The thread that shows you how is in the development section
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.

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

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

yes since 20i-20o-20p-20q-20r-20v all are the same. procedure.. we use the 20i procedure it came first.. BUT dont flash 20i when it ask you to.. since you already in 20r you will be doing this same procedure in 20r so step that says to flash 20i skip you have 20r firmware already... make sure you have LG drivers and for fastboot i used mininal fastboot adb.
