[Q] Help!!! Panicked. Stuck at boot loop. May have bricked my phone?

Hi, I am new to the forum. And very new to rooting phone. And due to my lack of knowledge, here's the problem that I have as a result:
I have an UNFLASHABLE GSM unlocked galaxy nexus gt-i9250. Had it successfully rooted two days after I had it 3 weeks ago. I have flashed MIUI via CWM premium edition and it worked fine. I recently flashed AOKP Build 32 with the latest Leankernel baseband xx66 and have been running it fine for 4 days until now.
I just flashed [Amoled BLUE 2.2 for AOKP build 32] and stuck on boot loop for 2 hours now.
I made NANDROID of my rooted stock, but the problem is that I DID NOT have it saved on my Galaxy Nexus. What to do??? Please help.

You're fine buddy.
Boot into CWM...
(Power phone off by pulling battery. Power on with power+volume up+volume down)
Select the recovery option.
Wipe data (factory reset)
Flash ANY rom.
You'll boot right up.
Now move your nandroid to your phone and restore.
Edit:
Oh, and check my sig.
The second and third posts may be useful to you.

Thanks. I did everything you mentioned and still stuck in the AMOLED Blue theme anime boot loop.
So, another question that arises is how do I flash rom when I can't get past the boot loop with no NANDROID or backups stored in my Nexus?

You didn't do what I mentioned if you're asking how to flash the rom.

Download the rom you'd like to try on your device.
Most roms also require you to install "gapps" as well.
You can find the correct ones for the rom you're using in the rom thread.
Make sure the Rom and Gapps are on your SD card.
Boot into ClockworkMod Recovery by turning your device completely off. Hold volume up, volume down, and power until the green Android with the open chest is displayed. Navigate to "Recovery Mode" with the volume buttons and select using the power button.
Remember to have a recent nandroid before continuing!
Navigate to "wipe data/factory reset" and select it. Select "yes."
Wait for the process to complete. This may take some time. Be patient!
Once complete: Navigate to "Install Zip from SD card" and "Choose zip from SD card."
Find the rom's .zip and install it. Once that completes install any applicable gapps' .zip.
Select the "Reboot" option.
Congratulations! Your phone should now boot into the custom rom!
Follow the prompts to re-activate your phone.

It describes getting your files transferred to your phone.
But if you have a rom .zip on there you don't need this.

I didn't asked for how to flash a rom. I asked how to bypass the boot loop. Argh...
Okay, I flashed Amoled blue for AOKP build 32. I get stuck on boot loop anime after flashing it via CWM. Yes, I did a cavlik cache wipe before the flash.
But I'm stuck on boot loop, why?

And I'm telling you how, mate.
Don't flash the theme.
Flash a ROM.
The theme isn't a full system...which is what you need.
And you need to wipe data.
Edit:
I'll take it by your lack of response that this fixed it.
You're welcome.

its stock JB rom flashed it over with galaxy nexus toolkit and downloaded the rom from google's site so its not a zip flashable
thanks all for replys and sorry for thw wrong section

im not sure but i remember on my g2x you could hook up phone from recovery mode and mount it on the computer with sd card .. have you looked around in CWM? This is your fault to be honest you deserve this for not making a NAND back up. ALWAys MAKE A BACK UP! period. There is a reason why devs and everyone else stress' it so much.

Sert00 is right. Flash any [previously] working ROM on it. It will be a dirty flash and some stuff won't work, but you'll be able to backup your data. You'll reflash again later

Unfortunately, at least with these beta realeases of JB, usb mount via recovery almost never work.
Try what sert00 told you.

Have you all the time connected to the PC? If "YES" you must, my experience, disconntect for first boot.
Also my experience, the first boot takes a long time. More than other boots.

Did you make a clean flash? (Wipe data and cache)

if you are upgrading from GB, better manually format /system too.
I had to do that the first time I isntalled a JB rom.

Have you try flash boot.img include in zip file. So, i think you forget this. Try reboot to bootloader and flash boot.img via fastboot.

to install CM, the best method is reboot to recovery, full wipe (wipe data, wipe cache, wipe dalvik cache, wipe battery stats), and go to mount and storage format system, then install the zip file + gapp. Don't forget flash boot.img via fastboot if you are S-ON. Hope that help.

Finally able to successfully flash a custom rom to my S-On HTC Desire HD. Thanks for your advise.

Nest time better ask in the ROM-thread itself.
Because the maker of the rom doesn't look trough all the threads.
And i would think the maker of the rom would know best.
I even looked up the link for you: http://forum.xda-developers.com/showthread.php?t=2093845

Pull your battery. Put it again. Do a key combination to go into recovery mode. Restore your backup or flash that rom again. Simple.

Just press power + vol up until 3 vibrations.
If you really can't go into recovery, use flashtool to flash stock ftf.

[Q] Stuck on karnel load, wrong rom

Similar case:
http://forum.xda-developers.com/showthread.php?t=1689420
So I made a stupid mistake but know where. This is not my first time to flash roms and karnels, but don't know where did I go wrong...
So here goes the story:
I had Racing Bean for a while and then I decided to change so I wanted to try the new Kit Kat
http://forum.xda-developers.com/showthread.php?t=2545367
First I went back to stock 0.587 (because I never did before) and then I forgot to install recoveryX.
After that I flashed the karnel (nAa karnel)
So now I can't go in to recovery to install the rom and wipe the system
I tried.
Volume Down
Volume Down + Home
Home + (Connecting the cable)
Volume Up + Connecting the cable
Maybe something more but can't remember
What should I do? Thanks in advance
ARC S (LT18i)
BTW: When the legacy logo loads a purple light blinks but nothing...

Well if you have flashed the kernel you should be able to boot to recovery... Turn on phone...as soon as logo comes keep pressing any button... The purple led will change to blue and it should take you to recovery...

Usually kernel is inside the Rom (zip file) when u download, u should go with that kernel for best compatibility.
copy the zip file to sdcard
extract the zip to get .img file, flash your device with that file.
enter the recovery and install the zip file u copied
wipe cache, data ...
install gapps if u want
wipe again
reboot

The logo starts to load (vibrates) and the purple light blinks and it's gone, so now stuck again.....
Thank you all
Never had this case.... I will wait for a while because of the first boot but didn't have this problem before.....
BTW: I use the V. Down to go in recovery (CWM 5 installed before this!!)
EDIT:
1.1 (optional): If the device is not booting, reboot to bootloader again and run:
fastboot erase system
fastboot erase userdata
Should I try this? One thing to check how do you go to bootloader on arc s (flashmod?)
