What are you using to flash? ADB, ClockworkMod Recovery? My rule for ROMS has been: download to phone and ensure download was completed successfully, reboot to CWM recovery, wipe cache, wipe Dalvik, install ROM, wipe Dalvik again, reboot.
If you can provide any more info regarding your process I can try and help you out.

Which galaxy nexus version is yours? Which Roms did you install? Did all three wipes?

@ooddiittyy,
I'm using the one from gnex toolkit v7(clockwork mod touch recovery) I did wipe data /factory reset 3times,wipe cache and wipe dalvik and I also format system,cache and data..reboot and stock in boot loop.. I did that to 3jb roms and same thing happens..so I restore to ics.and this time boot up well. This is the first time I've in counter something like this..been flashing since vibrant.

Try re downloading the rom again if its stuck at the Google animation let it sit for 5 to 15 minutes. It should boot up on its own. If not then there's something else wrong. But when I'm stuck at the Google logo with any jb rom I just let it sit. And eventually it boots up fine.

OK. Hmm. Go into recovery wipe everything 3x data/cache/dalvik cache flash the rom (don't flash a kernel) just the rom go back and reboot system now and see if that helps.
Edit: make sure u have over 50% battery before doing this.

Edit: this is the first time it happen to me..even though I unbrick ,luck bootl. Factory reset .. its so weird...

hey all,
not to highjack this thread, but I'm suddenly having the same issue.
I was on VanirBEAN v7 with the Popcorn Kernel that came with it.
I then flashed Franco's latest (384 GPU version).
Had no problems until last night when I let the phone run the battery all the way out and die completely. I let it charge for a bit, then tried booting and I'm stuck at the Google logo or get a reboot during the boot animation, depending on what I'm doing.
So here's what I've tried. All of these come with a wipe/cache/Davlik inbetween:
flash Vicious Toro JB V3 (stays on Google logo)
flash VanirBEAN v7 (reboots at VanirBEAN animation)
flash AOKP build 37 (reboots on the TeamKang animation)
selectively restore boot and system for AOKP 37 from a previous stable backup (reboots at the Android boot animation since in the ROM I had it set to not show the TeamKang boot animation)
I'm really at a loss right now. I'm trying a full restore on the backup I did before installing my first JB ROM.
edit: tried a full restore and i'm getting "Error while restoring /data!"... ugh.
Is my only choice to try Wugfresh's toolkit and restore stock and relock?

No one tried to fix permissions?
3x wipes, superwipe scripts..
That's not gonna help. If you wiped it once, it isn't there anymore.

I used wugfresh to back from fresh start and still if I flash jb rom I'm stock in jb rom.. done with 3 different jb rom. Same on all of them.. and yes I also did fix permission... I also did about mount and unmount regarding the system,cache and data... I'm tired of flashing and waiting in boot loop so I restore to ics gummy. I hope someone can help us with this...

I suppose you could try reinstalling the bootloader, or using one of the recent JB bootloaders and see if that helps. I can't think of a good reason why this should be happening based on what you've described, however. I assume you've checked obvious stuff like the MD5 sums on all your downloaded ROMs, etc?

Hi everybody!
I have identical issue, I did all possible, now I´m close to give it up. Yes, I checked all downloaded files by MD5 sums, I tried latest CWM, latest TWRP, gnex-JB-bootloader (…lc03). Today I tried also “Super_Wipe_Lite_Nexus”, but I can´t jump boot animation. I´m flashing roms long time, but this magic never happened. What else we should try to clear/delete?

Nexus boot animation delayed

It's always at random. But I've been experiencing whenever I reboot my phone, it stays stuck on the Google logo screen for like 3 minutes, then finally changes over to the new Nexus animation after installing Vicious Toro V1.
I've done a clean install (wipe data/cache/dalvik, format data/cache/system). Twice. This issue still arises.
Any ideas? Thanks guys!

Have you tried a different kernel to see if the boot up speeds up?

Yeah I've switched to Franco's. Still not fixed :/

Does this occur on full stock?
I would suggest flashing a stock image just to make sure it isn't anything ROM related, if you haven't already.

It might be ROM related. Haven't heard anyone else having any issues with it though.
I'll just stick it out and wait for the AOKP 4.1.1 ROM.
Thanks anyways guys!

tried many things to get to JB. still getting stuck?

Hey guys.
I was running paranoid android 4.0.4 and t was good but I wanted to go to JB. I tried for a long time and it kept getting stuck at the bootloader loop screen.
I formatted sdcard, went back to stock. Back to square one. got TWRP and rooted it.
It tells me there is an update I can go from 4.0.4 to 4.1 and I allow it and it STILL gets stuck at the bootloader loop.
I tried to manually put in a ROM again, the black AOKP one and still stuck in the loop.
I haven't got a custom launcher or anything. pretty much running stock and wanted to get to JB...
my phone is maguro.
Anyone have any ideas?

anyone?!

Are you talking about an OTA Official update? If so you need stock recovery, bootloader and radio. You can't flash an OTA without these. If you really want to go down this route, you will need to flash factory images for your device and start from fresh.

Have you tried CM10? I have had great luck on Euroskank. I tried AOKP this morning and ended up stuck in a bootloop but Euroskank AOSP and AOKP have both been great. Also I use the 0726 gapps.

thanks! I will try these tomorrow!

Download the following: Superwipe zip, and Jelly Bean Bootloader zip
http://d-h.st/jcO Bootloader
http://www.mediafire.com/?lxpw84fwtm5cj6w Superwipe Script
Use clockworkmod and flash the superwipe choosing install zip from sd first the the same for the bootloader then flash your rom. Let it boot up which can take a couple minutes at the boot screen

What worked for me was the Galaxy Nexus Toolkit. It allows you to wipe the entire system and replace it with a factory image. The factory image for stock JB is available now, so it's as easy as a couple clicks. It's the only thing that worked for me completely, i.e., no sdcard0 bug.
NB: It wipes EVERYTHING!!!!! Backup anything important.

Phone will not boot any kernel. WHY?

First a little background. I am not new to the android world whatsoever. I don't post much but have been lurking for years. I had a Verizon GS3 and just recently switched to T-Mobile a few days ago and obviously bought a T-Mobile GS3. My vzw phone had no problems. But for some reason my T-Mobile phone will not boot any kernel I try to flash. Roms flash fine but when I flash a kernel everything goes fine in recovery but my phone won't boot past the splash and I end up having to restore a backup. I know I'm flashing the right kernels. I am on touchwiz based ROMs and haven't tried any aosp Rom because for the first time ever I actually prefer an OEM skin to aosp. So basically am I missing something obvious. Anyone else having thus problem. On Verizon I had to root and unlock the bootlosder. From what I understand tmobiles bootliader was not locked down and all I had to do was root. Like I said. I've tried every touch wiz Rom and every touch wiz kernel with each Rom and none will boot past the splash screen. I always wipe dalvik and cache but even tried wiping data every time too and keep getting the same result. Any input would be appreciated. . Thanks in advance.

Shouldn't need to do any wiping of any kind. I only use AOSP/AOKP, though. May I ask why you even bother with custom kernels? They honestly seem like a waste of time to me.

Im just flash happy. Like to try them out. I've been on Verizon for many Years and am used to the developers over there. I'm still getting used to the devs over here. Don't know any of there work. I'm sure its all good though. Been using imoseyons lean kernel since the thunderbolt back in the day and have stuck with them. Just my personal preference. I'd like to try some of tmobolrs kernel devs work but like I said I can't get a single one to boot.

What kernels have you tried to flash? There are a couple that have ICS builds. Also, what version of CWM are you using?

I've tried all the tw kernels. Every single one with 2 different ICS tw ROMs. I'm not using the leaked jb tw. I'm stickung with the more stable ICS ROMs for now. I just don't understand. I've tried every one. I've been flashing a long time and don't get it. Im kinda new to Samsung though. First Samsung was the galaxy nexus. Didn't ever use Odin with it. Does anyone flash kernels with Odin. Maybe I should try that. And to answer your question I've tried twrp and the latest version of cwm from rom manager. And of course I'm using the ICS TW version of the kernels im trying.

It could just be your phone doesn't like them. There is another guy on CM10 and AOKP that can't get custom kernels to boot either.

The kernel source code was never released for any build from UVALH2 and beyond. So most of our kernels will only work with UVALEM and UVALG1 builds.
We got kind of lucky I think and ktoonsez att kernel was brought over and works. I think there's one or two others that work now too.
As far as described here go I think we've got some of the best! For an outstanding rom you should try FreeGS3. It works with most of the kernels and is an awesome stable rom. If you want a later build try wildcards XquiziT v70 based on UVALH2. Use ktoonsez kernel with it.
And just to note, the stock kernel is surprisingly good. So give it a fair shot as well. Though I can definitely see some potential advantages of custom ones as well.

Have you done full Wiping?
Wipe Data/Factory Settings
Wipe cache and dalvik
Flash Rom
Fix Permission
Reboot and don't touch it for 10 minutes
Reboot.
Wipe cache and dalvik
Flash Kernel (Must be compatible with ROM)
Fix Permission
Reboot and don't touch it for 10 minutes
Reboot.
See if this will work. Sometimes you have to let it breathe so it can adjust itself.

Have you tried uding odin to flash MrRobinsons root66 UVALH2? This will take you to fresh full stock plus root. Then try roms again.

Whatever you do................
Be sure to double check before you flash that kernel. Had my first SGS3 for 12 days before hard brick set in. Terrible disease it is.......! I had to adopt a replacement shortly after to cope with the pain of the loss. Back on my feet again now though and soarin' higher than giraffe vagina on the things I learned in my days off for mourning. I can tell ya I've personally flashed the lean kernel and kt-747 with no issues. My problems were with siya mainly.

Guys, I have a serious problem.
It's similar to the one of the thread-opener.
The diference is that I cant get ANY ROM to boot, WITH the stock kernel.
And i do like the guide says: wipe/factory reset, wipe chache, wipe dalvik cache and then flash the ROM.
Everything works fine til the ROM finished flasing and runs a reboot.
My S3 shuts down screen, then turns screen on with the "Samsung Galaxy SIII-GT-I9300" and then thats it!
All i can do is to go in download mode or recovery mode. I can also flash CWM and so on, but after flashing ROMs it won't boot!
Is it possible that i broke the device by formating internal sd-card with the stock recovery tool?
Did it, after I tried to install Wickedv6 ROM and after both times when it rebooted it just reinstalled stock ROM. So i thought, ok delete the internal sd-card, so no stock ROM on it any more.
Also tried this ROM: http://forum.xda-developers.com/showthread.php?t=1875923
Same problem.
Also tried to fix the problem by rooting and then flashing ROM. No help.
Please help guys!
Best regards

This isn't the I9300 forum, but if you flashed a T999 rom, you bricked your phone.

Wow, you scared the **** out of me
But i just tried to flash stock ROM: http://forum.xda-developers.com/showthread.php?t=1646610
It worked out!
What is the right forum for my GT-I9300 to post then?
And why isn't any other ROM working?

The forum you got that stock rom from is the international one. This is the US Tmobile T999 forum. The two phones are NOT compatible.
Only flash, well...anything, from that forum. Our roms will brick yours and vice versa.

[Q] Rom issues

So, i just bought my Galaxy S2 and started installing roms normally.
However the problem is that mostly every 10.1 roms dont work such as awesome Hurcules 4.6/ P.A.C. Rom, etc...
I did a full wipe-> Clean davik-> installed Rom-> Rebooted. And its stuck on the boot animation forever. ITs been around 10~15 min and still stuck

I had the same problem when I first got my S2. Surprisingly, CWM Recovery ended up being the issue. I switched to TWRP per members suggestion and problem solved.
