I have a Galaxy Nexus with Android 4.0.1

I tried to install Jelly Bean, and followed all instructions I found on a website (forgot which one). I installed cwh and twh first. Then I installed Jelly Bean. After the installation I rebooted my phone and it got stuck on a cross with the four colors for more than one hour. So I tried to remove all of this (Jelly Bean, twh). But now it's stuck on Google logo.

I tried everything. I don't know what to do to make my phone work. I flashed it but it's not working.

Can you help me? (A stressed student who cannot pay for the repairs)

Thank you , I really need an answer

By the way, I have a mac.

Do you have Nandroid backup of old ROM? –  Sachin Shekhar Aug 30 '12 at 5:17
    
Do you need your data from the old installation back? Probably not easily possible with your device' current state. If not, you can follow this guide to install CyanogenMod, a well supported aftermarket firmware with nice addon features (GNexus GSM VZW+ Sprint here). It's probably the fastest way to get your phone back into a working state. BTW: It's rather hard to brick the GN completely. Just leave a comment with questions in case you have some! –  ce4 Aug 30 '12 at 8:35

I had same experience once where I was stuck at a boot loop after flashing a nightly release of a custom ROM. I tried flashing several other ROM but to no avail.

The reason it happened on my Galaxy Nexus was because I had the option Automatic Restore enabled. You can find this option at Settings -> Backup & Reset -> Automatic Restore.

My fix was to execute the following command:

fastboot -w

This command erased the userdata and cache and I managed to boot my device successfully.

In case you don't know what fastboot is, it's a tool that's available from Android SDK.

Before proceeding with fastboot I suggest you to try flashing some other ROMs.

I had the same issue long ago with my G1. I forgot to wipe Dalvik cache. It's an option in the recovery menu, you should do that.
