[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.

Sent from my Galaxy Nexus using xda app-developers app

the guide is generically setup for windows. for ubuntu, you just need to use ./fastboot-linux instead

Wait, so you can go to recovery but not bootloader? Can you please confirm that? Because, if you can go to bootloader, you can use adb commands to push one of the ROM to your phone...

yes i can only go to recovery mode... when i choose to load bootloader it brings me to the main menu back..

You have a custom recovery? CMW?
if so:
adb push ROM.zip /sdcard/

Post three of the guide linked in my signature.

anyway thx... just send my phone to the centre... the technician were laughing at me hahaha...

That was the bootloader, where you use fastboot.

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.

adb is not the problem, your pc/windows is. adb is available IN recovery, not in bootloader, stop making that confusion jeez

Problem solved fixed it using odin.

thank you everyone for your help

Glad you fixed it. As you see, we all use different methods in the same situation, glad one of them worked for you.

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.

[Q] Possible Brick: Is a jig my only hope?

I did a duma$$ move. I flashed a rom on top of a different rom without wiping.
- Phone boots up
- Boot animation displays
- Freezes on 'Android' Screen
- Does not go into Recovery
- Does not go into Download mode
- PC doesn't see it, but pc makes a sound when I plug it in, and drivers attempt to install when I plug in to pc (fail)
- Kies takes a while but I got "This device is not supported by Kies 2.0. Please try again'
Any and all help is appreciated.

if you got into download mode and odin'ed back to stock and it gets stuck on the "samsung with the blue logo behind it" boot screen than you have to go to stock recovery and wipe data and cache there and reboot, i had the same problem earlier but mine could get into recovery and download mode but it wouldnt wipe the data it would just turn off whenever i tried to

HOLY S-H-I-T SNACKS! I got into download mode. Rather then pressing Volume UP + Home + Power, I did same but Volume Down, and I'm Golden.

How'd you do that? I might have the same situation.

to get into the stock recovery you hold volume up and home and the power button at the same time, use the volume keys to move up and down and power button to select than wipe data and cache and reboot

No Recovery!

I installed FTL 4.3 ROM and gapps core 4.3 and now I don't have a recovery. I use to have cwm 6.0.3.3 with touch but now when I boot into recovery it shows the android belly being open with a red exclamation mark . any help ?
