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.

this makes me die a little inside.
also, cwm touch is known to have issues with flashing stuff.

Oh.. so I think I should use rom manager.. to flash vicious-toro v3..

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.
Sent from my Galaxy Nexus using xda premium

I did that last night..wipe 3× everything.. did flash just rom, then rom with kernel, and also I did try wipe just cache and dalvik.. and also I did try format system, cache and data...
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?

Help I'm stuck in a boot loop

Yesterday I tried updating to CM9 alpha 6 and when i updated i got stuck in a boot loop. it wasn't a clean install from 5 then when i got to the bootloop i did a factory reset and I'm still stuck. Someone told me it was possibly a bad ROM file. He told me to reflash a kernal and see if it boots up and if that doesnt work try flashing a newly downloaded CM6 Rom. I flashed the FF11 kernel and now i cant boot into recovery. If i hold power and up, it just boots normally put gets stuck in the CM9 animation. Any help would be greatly appreciated!

Try to Odin back to el29 that should do the trick just would have to start everything all over again.

Ok so let me see if i got this process correctly, odin to el29 which puts me back on GB TW, then i boot into recovery then install the ROM? do i need to reflash gapps? also another question. I did a factory reset on my phone, that doesnt delete the internal storage partition that the phone reads as "sd card" correct?

Yes factory reset does not delete internal SD memory. You don't have to go back to gb. Just go into download mode, Download el26 cwm kernel and flash that through odin/PC and wipe everything. Flash cm9 alpha 6 and gapps. Should be good to go.

Nandroid Restore Help

I'm new to Samsung Android phones, and new to the E4GT, so I need a little help.
I always flash the zip for the EL26 CWM5 recovery like instructed, soooo, here is my issue.
I'm running AOSP and thought I would try CM10 JB, soooo, I flashed into EL26, performed a full nandroid to my Ext SD. I flashed JB and gave it a shot. For issues known to all, I wanted to switch back
So, I went into recovery, flashed the EL26 recovery and rebooted recovery, I then restore the nandroid backup I just made, rebooted, went to the Samsung screen (with the yellow !). After some time, about 20-30 seconds, it goes to a black screen indefinately until I pull the battery.
Any ideas? I have yet to get a nandroid to work on this device. Had no issues at all on my 3D. I'm sure I'm doing something wrong.
TIA,
Tee Jay

You need to flash the AOSP kernel. Well first can you boot into recovery or download mode

Yeah I can get into recovery fine, so I flashed an AOSP kernel and then my wifi didn't work.

Is it not connecting?

Nope, won't even turn on. But if I do a full clean flash of the exact ROM, it works fine.

I'm by far no expert but I'd say the kernel is being replaced by the gb recovery kernel when you flash back for your safe recovery.I personally keep a couple various recoveries so I can nandroid backup on the kernel native to the Rom and then the backup will contain the proper kernel.I think I got that right.so....nandroid b4 recovery has been my habit.

Had this issue before, minus the yellow triangle....anytime you're on an aosp rom and do a nand via el26, the nand stores the last kernel used (which is GB el26). After you restore, wipe cache and dalvik and then flash an aosp kernel, probly one from chris41g. Reboot and should he good to go.

Right, I tried that with my AOKP backup, I was able to boot. But then my WiFi wasn't working because of something to do with the Kernel I'm assuming

Unsolvable problem?

Ok so I installed a Kernel on the LI7 JB leak that allows me to adjust voltages. I adjusted them too low and my nandroid backup is corrupt. If I flash a kernel that doesnt allow voltage changes the phone works fine but one with UV it wont boot. Im trying to find out how to manually set the voltages back to stock.

apps like setcpu comes with a recovery zip you can flash in recovery if you do this.
https://www.dropbox.com/s/eqdm45yy81x7yin/setcpu_safemode_toggle.zip

Ok I appreciate the file but it still didn't work. At this point I have even tried wiping the phone and flashing a fresh copy of the LI7 leak. I then flashed AGAT's v. 3.1 kernel and the phone gives the initial samsung logo then black for a few seconds and reboots. If I flash AGAT v. 3.0 it boots and works fine. Also if I flash another kernel with OC and UV it works fine. At this point I went back to an old nandroid from ICS and wiped all partitions and restored the nandroid including boot. The I reflashed the LI7 and the AGAT 3.1 still boot looping. Still all other kernels work fine. At this point Im out of ideas.

Are you mixing JB & ICS kernels and roms? There is no LI7, there's an LJ7 and that would use Agat 0.3. Just making sure because mixing kernels from different versions will cause bootloops.

Yes sorry LJ7 after agat 3.2 came out everything worked. Still can't flash 3.1 for some reason but as long as 3.2 works im fine

Phone Dead, Bad Night, Help Wanted

I flashed TWRP 2.5 and then flashed Task's AOKP 4/9 ROM and everything went down hill from there. The phone kept rebooting after a minute or so, so I did a factory reset and reflashed the ROM. That didn't help, it actually made it worse in that it would not get past the kernel splash screen. So I did another wipe and the same thing. I wiped again and flashed an older version of AOKP 4/5 and again would only get to the kernel splash. After another hour or so I decided I'll just go back to rooted stock, so using Odin 3 3.07 I flashed my trusted root69.stock_ATT_I747UCALG1 image and now it just stays on the Samsung screen.
I've run out of thoughts on what the hell is the problem and thought I'd ask.
Anyone have any suggestions on what I can do to get this paper weight working again?

Not sure about the problem with aokp. But your bootloop just pull the battery, reinstall battery, go into stock recovery, factory reset and voilà

Same thing happened to me. Boot loop with 4/9 AOKP task so I Odin to the same file as you but that ran just fine. I would try to Odin again.
Oh and after stock with root I flashed 4/9 and all was good. By chance did you have custom boot animation?

I think it's the custom boot causing this issue. Anyway good luck. I know my heart skipped a beat when my phone would boot loop while to get into recovery. Once I Odined back to stock with root first/only thing I downloaded was goomanager and installed TWRP then flashed 4/9.

I'm back up and running again. A little embarrassed I forgot the factory reset last night.
Thanks for the reminder!

AOKP is a great ROM.
When flashing ROMs always follow these steps and you will be fine.
1- nandroid backup
2- format system
3- wipe cache
4- wipe Dalvik
5- factory reset.
Most suggest doing each 3 times.
6- install ROM and reboot
7- flash gapps
Let sit for 10 minutes.
Follow those instructions and everything will be fine.
