[Solved] Downgrade Galaxy Nexus from jb to ICS-->You did it? help me please :)

It sounds like i am a idiot, but I am facing a lot of problems on jelly bean (official).
Is it possible to downgrade my official jb software to ICS 4.0.4 official without having to root it?
Sorry for my noobness, I am new to this device
Thanks for your time

that guide doesnt require root or cwm... just an unlocked bootloader.

I don't have that too... And I want to revert back to ICS
Is it possible??
Sent from my Galaxy Nexus using xda app-developers app

without an unlocked bootloader... no not really. even if you used ODIN, it would unlock the bootloader then relock it.
is it really so hard to type: fastboot oem unlock ?

its either manual or ODIN.
i will always prefer manual since its not that hard.
either method will wipe your device too btw.

Ota jb update failed signature

I have a rooted galaxy nexus and went to install the ota jb update. It gave me the red sign in cwm and said failed whole package sign or something like that.. now it says no update available. Anyone know what I should do to get jb update without wiping?
Sent from my Galaxy Nexus using xda app-developers app

you clearly modified system files. you need to find the files you modified and change them out to ones that are unmodified.

Yeah.. I changed recovery from boot.p to recoveryfromboot.p.bak as that's what a tec said to do after rooting if cwm didn't stick... can I change it back without breaking root?

That's not the reason why. You must have changed your radio or kernel or recovery. The ota update won't install ota with cwm

you are confusing root with a custom recovery. they are not the same. to get root, you have to have a custom recovery (least on anything 4.0.4 or higher). you do not need root to have a custom recovery.
if you take the OTA, you will lose root anyways and then you will also lose your custom recovery.

So I have to wait for a rom build and flash it to have jb with root??
Sent from my Galaxy Nexus using xda app-developers app

I think there are plenty of JB roms out there from the announcement in June. I could be wrong, but if you're just looking for the new radios, I think they can just be flashed over your current setup.
Sent from my Galaxy Nexus using xda app-developers app

No. You can accept (or flash) the OTA & then root it.

You need to have a read of this thread. And then, maybe have a read of this one if you think it's easier.

That confused the hell out of me.. and I'm not dumb. Lol. The second one doesn't mention toroplus from what I read.
I think I'll just update and reroot.. my problem is.. do I have to change that system file back to its original? And then do I have to download the update from somewhere BC my phone says up to date now?

No, I'm pretty sure you'd need to relock your boot loader and have stock recovery

Why would I need to relock the bootloader?
That shouldn't be required for an update... I know it wasn't when I went from 4.0 to 4.1

You don't need a locked boot loader or stock recovery. OTA's apply fine with unlocked boot loaders and custom recoveries.
You will need a stock /system though and any other file that's being patched.

The OTA won't apply automatically with a custom recovery. You have to move the file and flash it manually.

Correct. Assuming you're rooted and unlocked this is a fairly trivial operation.

ROM incapable to OTA

I am in 4.2.2 and tried many times to OTA update to 4.3 but it always failed.
Looking in the ROM Manager first screen says that my ROM is not set up to receive OTA.
There are no other options as these are for premium users of the app.
What can I do?

Flash it manually via fastboot.

Well I tried to do so using the nexus root toolkit by Wugfresh but it doesn't seem to work for 4.3 yet.
My other option is to download the file from Google and flash it with the Gal.Nex. toolkit.
As you see I am not very good with commands etc and I am trying to do it the easy way..

Why the h... is it unable to OTA?
It's a completely stock jakju 4.2.2
Sent from my Galaxy Nexus using xda app-developers app

something isnt stock. it could be the radio, kernel, some system file you modified.

When it errors out it should tell you where the problem is.

There are some system apps that I have deleted or freezed. It might be it?
In another thread here in xda I read that the device should be in stock recovery in order to accept the OTA update. Now mine is in clockwork mode.
Is this right?

Sigh. CWM doesn't stop otas, modifying /system does that.
If you removed system apps then that's your problem. You will never be able top install the OTA in any way

The T999L is the Superior Cousin T999 never was. It has an LTE antenna that the T999 is missing. Practically all the Custom Roms will work fine from one to the other.
If you want to flash custom Recovery then use Goo Manager and hit Install Custom Recovery Script.

Yea already tried goo manager but it said no recovery scripts were found for your device

You need to use ODIN to flash that Version. There's plenty of Tutorials on How to use ODIN.

I know how to use it, I tried it last night but everything fails.

Could be your Bootloader is locked.
Are you absolutely sure you are successfully Rooted ? Please use Root Checker App if in doubt.
When you tried to flash the Recovery via ODIN, what was the error ? Can you post a screenshot ?
With due respect "Everything Fails" doesn't really tell me squat.

I'll do that when i get back home.
Sent from my SGH-T999L using xda app-developers app

i tried it via odin again and it worked i have no idea what was wrong with it, thanks for finding those TWRP files for me.

Do a quick search before going any further. I have a T999L thread that answers most any question you may have.
