Downgrade GSM Gnex to 4.0.2

Hello
Today i recieved the jellybean ota update. its not working. i searched for a while and found out that ill have to update it with something called cwm and this requires root, but i dont want to root my phone. so i thought it would be possible to downgrade my device but apparently this also requires root. I have an unlocked bootloader but is there no way to update/downgrade my device without using root?

cwm does not require root, just an unlocked bootloader.

[Q] Upgrading to ZVC From ZVA Rooted

Hello,
I have a G2 Running Stock LS980ZVA Kernel Version 3.4.0. Now I rooted the stock ROM and now got a notification to update the ROM to ZVC.
Now my dilemma is do I "Restart and Install" this update or not. Will this brick my phone?
I have TWRP running as the custom recovery. What should I be doing? I tried to search for a similar thread but couldn't find one.
Any help will be appreciated.
Thank you!

You will brick. Either hold your finger on the notification and then click app data. Click on the show notification. No check mark. Notification will go away.
Regular reboot will not install the update.
If you unroot and put regular recovery back. Then you could.

I had the OTA downloaded but when i tried installing it, it did not install completely. Phone restarted and is still on 4.2.2 . Everything works as normal though, as I have been prompted 3 times to install the update.

okay, i did some research and found that it is safe to install OTAs but if youre rooted youll lose the root and unlock will still stay.
best imo, is you upgrade to 4.4.2 and root again with custom recovery and install a nice ROM.

GT-N5120 (Note 8.0 LTE) How to root after ota 4.4.2 kit kat update?

Helppp!
Hi, I have a samsung galaxy note 8 LTE, which i just updated to 4.4.2.
How do I get this rooted?
-Do i follow this thread? http://forum.xda-developers.com/showthread.php?t=2291839
Seems like that's only confirmed for 4.2.2..
What else should I take note of? I've read things about 'Recovery' and unlocking bootloader.
-Should I do a recovery? How do I do that?
-Do I have to worry about the bootloader?
-Will I be able to get further ota updates after rooting?
Should I wait for 4.4.4 before rooting?
Thank you in advance. I've done alot of reading but I'm still paranoid and confused...

I have all of these questions!
There's so much information in these forums, and it's very confusing.
I simply can't find a guide for how to get from Kit-kat on the Note 8 to rooted and with civato's ROM (would love some increased pen accuracy).
Any help would really be appreciated!

I don't have a 5120 but everything I have read confirms that CF Autoroot works without issue on that device. Just make sure after boot up you install SuperSU, update binary, and set it to apply upon system boot. If it doesn't work the first time keep trying. As a warning....this root method will trip Knox and void your warranty. Can follow the steps HERE to root.
You will want to install a custom recovery to flash roms (PhilZ or TWRP). However, changing the recovery, bootloader, etc. will prevent you from taking OTA updates. This is not such a bad thing because you never know if a new OTA will destroy root and lock the device. It is better to let the devs modify it first and then flash it safely. Usually only takes a day or so for devs to do this.
As for changing the bootloader, it depends on the rom you flash. Some will be fine running from older bootloader and some require the KK bootloader. Just check the first post of the rom and it should give you the requirements.

You can use CF Autoroot to obtain root and then install custom recovery via Odin as well. Then you can flash whatever rom you want.

I just wasn't sure on the details of these steps, and wasn't sure where to find more detail. I think I've figured it out now.
First I'd follow these steps: http://www.theandroidsoul.com/samsu...n5100-wifi-philz-touch-advanced-cwm-recovery/
Then, I'd use philz to install the custom kernel (edit: and ROM). I haven't been able to find any step-by-step instructions, however. But these seem close enough: https://www.youtube.com/watch?v=aDOY3Oi1VX8
Does this all sound correct?

I do not know of any root method compatible with the N8 that will not trip Knox. Towelroot is not compatible otherwise it would be an obvious choice.
Yes...looks like that walkthrough will work fine for installing PhilZ.
Why are you installing a custom kernel? Are you sticking with the stock rom or flashing a custom one? A lot of roms already come with the kernel packaged.

I'm installing a custom ROM & Kernel because the accuracy of the pen is not very good on my device, and I primarily brought it for note taking. My understanding is that civato's ROM/kernel will fix this (hopefully!).
But I didn't mean to imply that I'm only installing a custom kernel but keeping the stock ROM. I was planning on doing both, as described in civato's kernel+ROM release thread.

Ah ok....after you get PhilZ on there just flash civato's rom and you will be good to go.

Hi CCallahan,
Would you please confirm whether the method described in the link you mentioned to root Galaxy note 8.0 GT-N5120 running android 4.4.2 would work on note 8.0 i467m (LTE canadian version) running on 4.4.2?

The procedure is the same but you want to go and download the CF AutoRoot for your device here: http://autoroot.chainfire.eu/
Your device is on the list so is compatible. There are also some basic instructions listed for how to root.

Thanks for your response. I have only one corcern left. In the link you posted, on top of the table of CF-Auto-root, it mentions that if the bootloader is locked this might brick the device! How can I make sure that my bootloader is unlocked prior to start rooting.
Previuosly, I had my note 8 rooted with CF auto root via odine when it was on jelly bean 4.1.2. Does this mean that it is safe to root it again with new CF auto root for 4.4.2?

It's just a warning pal I rooted fine from 4.4.2 with chainfire autorotate it's just a precaution before proceeding as with any flashing procedure it contains a risk of bricking

How did you update to 4.4.2? Rom flash or OTA? Did you manually update the bootloader?
As far as I know Samsung doesn't usually lock bootloaders unless it is carrier dictated. It is usually common on HTC and Moto devices.
Better to be safe than sorry though.

I updated to 4.4.2 via Kies with samsung's released firmware. I havent done any other flashing apart from this. So, I suppose rooting must be fine, right?

Sorry but I can't/won't confirm whether or not that particular model is safe to root after 4.4.2 upgrade. Maybe someone with more knowledge on that version can chime in. I wouldn't think it would be an issue but don't want to steer you wrong. The bootloader could be locked.

No I can't. But I see no reason to doubt what he says he's done himself. I do know the method he mentions was verified for several lollipop ROMs by multiple users.
OTH. Until I read the post above, IIRC, that's the first I've heard of it working on KitKat. TBH, I've not attempted this- "works on any ROM" concept but stayed close or with my bootloader. OB7 bootloader running OG5 being the biggest exception. But I've also made exceptions for kernels and modems but stayed close to revision of bootloader. I feel max compatibility is where they all match. When possible, that's what I run with.
KitKat may boot with your lollipop bootloader and lollipop 5.1.1 custom rooted kernel but how stable and compatible is it? For me, KitKat WiFi Calling was never stable. Not saying it's a total waste of time; use at your own risk.
I can't affirm with absolute certainty that Odin won't allow you to downgrade once your bootloader is greater than OB7 (because I never tried it, myself) but I can say MANY reported and posted failed Odin logs to confirm that. (That is confirmation). AND some had to use Philz CWM touch recovery for Note 4 to factory reset and flash in recovery after TWRP failed to flash afterwards and for a time; there were a few to confirm this. Don't try to "downgrade to KitKat with Odin" unless your bootloader is OB7 or less. If bootloader is greater than OB7, use recovery only plus the kernel mentioned for downgrade. It's a risk vs reward to consider yourself.

Custom recovery/root on MM??

So I've rooted plenty of phones... just switched from Sprint to Verizon.
Rooted/installed custom bootloader on my Sprint Note 4 no problem, but I'm not seeing a way to do it with this phone already running MM.
If you can give me instructions that work I'll PayPal you a beer!

There's no way to root and unlock the Verizon Note 4 bootloader while on MM. You'll need to downgrade to BPA1 firmware, which is LP, before you can start the rooting process.

So downgrade with that firmware image in Odin, then follow the instructions on here to unlock the bootloader, root, and then update back to MM?

you need to start on bpa1 (5.1.1) temp root, unlock BL , twrp via Odin , perm root then unless you plan on staying on lollipop you have to repeat the process to via the safe upgrade to get on the current BL cpd1
