[Q] Boot loop problem after rooting. - Samsung Galaxy Nexus

Hey folks,
A friend of mine with no prior experience of rooting decided to go ahead and root his GSM Galaxy nexus anyways.
The guide he followed is this one. http://www.youtube.com/watch?v=5AvJI4ucOL4
At that time the phone was on ICS. Rooting was successful and the phone was working okay. He then updated to JB using OTA update. The phone rebooted but has been stuck in a boot loop ever since. On the very odd occasion like maybe 1 in 10 times the phone does actually start and goes to the lock screen but then restarts immediately and is stuck in a boot loop again.
Any ideas as to how the phone can be un-rooted and the returned to stock JB?
Many thanks.

I wonder where I might find something like that....

Thanks for the links mate. Just was not sure if the same would be applicable to a phone stuck in boot loop. A bit scared after managing to brick my own EVO3D last week

I tried following the instructions given in the link posted by Pirateghost but that requires to access the CWM recovery mode. When I try and enter recovery mode I get a sleeping droid with a red triangle and exclamation mark. I assume this is because my mate tried to do an OTA when he should have downloaded JB and installed it through CWM.
Any ideas on how to return to stock now please?

Guides indicated by Pirateghost give you all the information to flash the stock rom and also explain to you regarding the disappearance of the custom recovery .... in case, if you're under windows/mac, try the Nexus Root Toolkit, has the GUI and it's easy to use as long as they are properly installed the drivers to recognize the phone ...

Do it with your friend, or you'll have to do it again in the future.

@Shark_On_Land Hey man!!! I would go step by step back to the forums and just read, i just got done installing my first rom after rooting, etc.. etc took me 8 hours but learned ALOT,... got a few boot screens with big red triangle a few times but hung in there... Point is i missed several steps and didnt write a post, cuz like the small tutorial said in the beginning someone else most likely already had your problem. If not then I hope you get the help u need soon... aside from all that XDA ROCKS!! ty guys!!
I would back up any/all data (nandroid+Titanium), then flash a rooted ROM after doing a full wipe, then your caches of course. It sounds like you are using the ROM that came with your phone. You can get into RA Recovery can you?
Not sure what your saying here. Your not the OP. But I take your post is intended for the OP so I won't make a snarky remark.
Congrats btw.

Vzw nexus wiped system

Hey i accident did a system wipe instead of doing a regular wipe and i can only boot into fastboot mode now when i try to boot normally it only stays on GOOGLE screen with the little unlock symbol but like i said i can get into fastboot mode. I tried using the Gnex toolkit 7.4 but it wont downlaod any roms because it says it cannot connect to Goo.im anyone know how i can get a rom on this thing? THank you in advanced.

Well...coincidentally goo.im is down.
But use post 3 of my guide (or your ******* toolkit if you insist) to push a rom.zip to your phone and install it.
Wiping system just wipes the rom.
So if you have a download for the same rom you were on...you can simply flash it and not wipe anything.

d710 icsFL24 stuck in bootloop after installing agat recovery

I rooted the stock OS with SPH-D710_FL24_CL1173404_REV2_Rooted_Nodata.exe and everything worked fine. Then I installed MobileODINLite-v3.85.apk and did the SXTP_Agat_FL24-v0.4.0.tar flash, and upon reboot, the OS loaded up fine, but after a minute the OS would lock up and the phone would then reboot on it's own, and it just keeps doing that no matter what. I've already tried going back into recovery and wiping cache and dalvik, no change. What should I do?
BTW, I'm a noob to smartphones, the reason I was doing all this is because I can't transfer any files to the internal USBStorage folder either by KiesAir or by physical connection to the pc, I just get a transfer failed error. I was trying to make a recovery so I could load a custom ROM (dirty unicorns) in hopes that this would fix the problem. Also I don't think taking this phone to Boost for a replacement is an option, since I bought this phone used from the previous owner. HELP! =(
Look guys, I'm not someone who is too lazy to use google. A week ago I didn't even know how to use this device. I've tried looking around but I'm gonna need someone to point me in the right direction, so seriously? 33 views and nobody can at least do that to help me?

What I would do is download the GB27 Rooted Odin here-http://forum.xda-developers.com/showthread.php?t=1903252
And update to JB and maybe that might fix some of your problems. You can get into Download Mode by pulling the battery and replacing it and holding Power+Vol Down.

Messed bootloader unlock

I've tried unlocking bootloader using official Unlock app from Asus
I've the latest firmware 2.20.40.168 unrooted.
I've tried it thrice, all I see is is a black screen with a USB symbol and full white bar below it.
I can't enter the bootloader itself.
I've tried reflashing droidboot.img, boot.img and recovery.img. All says <waiting for device> infinitely.
"fastboot devices" displays nothing, my deivce is not detected!
Yet, I can enter the OS and use it flawlessly!!
Please help me enter the recovery please!
I've attahched the screenshot of the black screen when I press Power+Vol Up (release power up upon vibrate)
Thanks in advance!!!

I cant reach the bootloader, how do I flash a custom recovery? Sorry, I'm no genius...pls guide me with a link!
Thanks in advance
Your phone is bricked! Search for unbricking with xfstk in the zenfone 2 threads. Your phone should be recognized as Moorefield when connected to a PC.
Your other option is to go to a Asus service center or send it to them, but your warranty could be void, because of using official bootloader unlocker!

You said it too fast. He's able to boot to system properly but unable to enter bootloader.

@krasCGQ
Yeah, you're right! Too fast to say bricked!
But afaik xfstk is the only way to get droidboot/fastboot back.
As far as the phone wouldn't be recognized as any other than Moorefield.
Even if adb can recognize the device, one could not flash droidboot with that, right?
... Or perhaps I'm just talking bullsh*... I'll better quit now... [emoji32]
I'd say bricked too, even though you can run the OS when a new update comes out it won't update if it can't go to recovery. In fact it might just start a bootloop...
If it bricked while using the "Official tool" then I'd return under warranty, it was working fine before... As has been said, the IMEI number was registered with ASUS when unlocked, I just wouldn't wait too long as the longer you wait the less chance of being fixed under warranty.
At the very least you can ask about it and see if you can get it sent back for warranty fix, just don't say anything about flashing anything but bootloader...

SM-T320: Odin Failure while trying to root

Hey all,
First time I'm trying to root this device, and a long time since I've rooted any device, so I'm a bit rusty ...
While trying to flash with Odin, I'm getting this error (looks like a write permissions error?)
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

This is what's shown on the device after:
The current firmware on the device is the stock 4.4.2, and I'm using the latest CF Root for it: cfar_samsung_sm-t320_mondrianwifiue_kot49h.t320ues1aqa2_t0
Update:
I also went to updato.com, grabbed my latest firmware, flashed it in Odin (it passed), then re-tried the above: result was the same as above.
Any idea what step I should take next?
TIA

It's been so long i can't even remember the steps i took but if i were to do it right now I would probably flash twrp in odin, reboot directly to recovery and flash supersu.

Thanks, but you have to root before you can install a custom recovery; I'm stuck at trying to get the chainfire root installed.
I'm still stuck, anyone have any other advice?

If you bothered to follow that guide i included you would see that too. But ok...

Hi, sorry for reviving an old thread but I had this issue last night and wanted to share how I resolved it
I have the same T320UES1AQA2 model but couldn't get the CF autoroot to work either. I ended up going into recovery (Power + Vol Up + Home) wiping data and then flashing CF-Auto-Root-mondrianwifi-mondrianwifixx-smt320.zip which worked perfectly.
I know this is super late but hope it helps and anyone else who stumbles across this
