[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

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 ?

either method will wipe your device too btw.

If you have the images (and you do, since there is an Odin stock tarball floating around), you can easily re-pack them up to flash in CWM...

If you can still use your USB port, I would recommend the link that Petrovski80 posted.
If you cannot use your USB port, then it is a bit trickier. You will have to:
1) Ensure you have root and a custom recovery;
2) Lock your bootloader using BootUnlocker
3) Flash the stock kernel in recovery
4) Flash the stock ROM (i.e, the /system folder) in recovery
5) Flash the stock recovery in recovery.
EDIT: I posted how to do this somewhere, but I can't remember where it is now. A quick search should find it.

Or you could use mobile Odin. I've never used it myself. Make sure you lock the bootloader first though.

Not packed the way it is, no. You need an Odin repack. Look in the dev section.
Sent from my Galaxy Nexus using Tapatalk 2

What the steps in your case should be, by my knowledge:
- Try extracting the .tar containing the actual img files by using an app like ZArchiver on your /sdcard
- Lock the bootloader using Bootunlocker app
- Reboot into recovery
- Flash appropriate img files
- Reboot into Android OS at least once so android will overwrite your custom recovery with stock
Disclaimer: none of this is tested, just theory.

If i can unzip it i think mobile odin can flash it i guess

No os installed

Erased everything from twrp 2.20 now it doesnt get past the google logo it says i have no OS installed. Im rooted on 4.1.1 how can i install the OS???
Sent from my EVO using xda premium

you formatted the system partition.
i assume you formatted your SD card. so you have 2 choices
1) you download whatever custom rom you want on your pc and use: adb push locationofrom /data/media/
2) you use fastboot to restore to stock.

How can i use fastboot to restore to stock?

adding to that, adb only works in recovery. from fastboot, restart recovery, push a rom, flash it. no need to reflash stock images in this situation, imo.

There is the nexus toolkit that has all you need. Its stickied in the sprint section. You can flash a ROM through there.

With android u don't have to worry about anything if it's software based problem. Every problem can be solved here. We've got the best devs here that make everything is just possible. That's what iphone users can't have. They have to wait for apple for every fixes while we don't.

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.
