since you didn't do a Android your basically screwed so all you data is gone you only hope is to transfer a file through fastboot(can you even do that?) Or boot to Odin mode and flash a stock image

GSM or LTE Gnex? What ROM were you running?

Golden rule: Do a backup before doing anything to your phone!
Now all you can do is to download EXACTLY same ROM as you were using by now, wipe cache/dalvik-cache, flash this ROM once again and hope that i'll boot. If it won't you'll have to wipe /data is well.

ouch... softbrick.
put your phone down.
take a deep breath or two.
If you are old enough, grab a beer and relax for a bit. Think calming thoughts.
Now, start learning about how to mod your GNex. We can help.
Here's your First assignment:
find out if you still have a bootloader by booting into fastboot mode. Report back with your findings and a screenshot!

Still have a bootloader? Are you serious? You need to learn how to use an android device as well.
To the OP: Do a factory reset in Clockwork and go to mounts
and format /system. Flash the ROM zip. Profit.

Absolutely serious. Have you been reading this thread? The OP needs to start at ground zero and stop just trying every tool he/she sees. My purpose was to get this person to do some research and I was establishing a knowledge baseline. One plan I was considering was to help the OP install the GNex toolkit then locate stock images and obtain a working build. Your cryptic one liner bit should prove vastly more useful to this guy though. I'll let you have at it and go back to my dev work. lol at least this post was a good way to make sure gapps/root capabilities are properly cooked into my latest test build ....

U r right i am not good in android but i tried to be and this happens, meanwhile nothing shows after i start the device it shows the !!!! mark with device the PC logo,this happens due to ODin actually the SUMSUNG ADB interface shows ! mark because i cant debug from device even no bootloader works any more thnkz for replying

*facepalm*
OP, you are holding it wrong.
I can think of at least 2 ways to recover from a situation like this. Both are well described in these forums (search works 99% of the time).
....
Oh come on, you don't have the zip of the last rom you flashed, get another one, hey, its free right? **** we dont know nothing about but we'll flash it anyways!
Man...If you have cwm recovery, you're safe. No need to go messing with fastboot (forget odin) just yet. Now stop wasting everybody's time and learn to help yourself.
Here's a few tags to get you started:
cwm, recovery, adb, bootloader, fastboot

i tried more than one day on this issue its only starts with !!! mark on it nothing else, i have attached the pic i cant access any bootloader or any cwm or any thing all i did with Odin and stuck to attached pic even i start the device its shows the same pic.
http://www.youtube.com/watch?v=WdM2M8Nz6QQ this I used on Odin
thnkzz

As I suspected earlier, it appears that the OP may have trashed his bootloader partition when he tried using Odin to flash the 4.0.2 factory image (which includes a bootloader). At one point he had CWM but not any more since he can't boot to the recovery partition.
Another possibility is that the Odin tool itself places the device in this mode and it can't be manually reverted by starting up in fastboot mode. Looking at the picture, it literally appears that the phone is saying that a flashing operation is half finished but the phone has lost the PC connection... This would be a lot like what I've experienced with iPhones.
In either case, I can deduce that Odin is the tool to use to clear this softbrick.
Hopefully, it'll be flame-off now Sdobron. Perhaps you might want to help out here since I'm not up to speed on the Odin tool myself and would like to learn more about it.
@salym: I know this may be redundant but I need to establish your problem baseline empirically. Once again, can you verify that when you hold vol down/vol up then press power that you get the image you posted?

Use Fastboot!
Dude, it looks like your problem is with crappy boot sector.
While turning on your phone, hold both volume up and volume down buttons, and long press power button untill you feel single vibrate feedback.
Then connect your phone to the computer via USB, and if it doesn't detect drivers, google "samsung android usb driver". Additionally you can install PDANet application (X64 or x86 depending on you system).
THen download Fastboot - there are plenty of instructions how to flash it, and flash stock images (that come with radio, boot sector, rom itself, etc) - there are also plenty of discussions about how to do it. PM if you have any other questions!

Bricked in the 12 hours I had this phone? :S

Just got this phone less than 12 hour ago.
I have searched everywhere but cannot find any answers.
So first of all, I have rooted, and unlocked my bootloader. I then proceeded to install CM 10.1. Install went perfectly, but when I restart the phone, the LG splash comes on for less than a second and goes straight to a backlit black screen. No matter how many roms I try to install, they all do this..
I have installed LGNPST but when it recognizes my phone, it goes into emergency mode and under DEVICE it says "Unknown"
I have all of the drivers for my phone
If anyone could help me and say what is going on I would greatly appreciate it. I have looked on these forums for atleast an hour before I decided to post this thread.
I have the E971.
Thanks all

Download the Rogers 10d from here: http://lg-phone-firmware.com/index.php?id_mod=20#rogers
LG Optimus G E971/3/5

Thanks guys. For some reason, the KDZ updater wont let me choose the file to update/ Instead of the yellow folder to locate the file, the text box is empty and the button to find it is no where to be found...

try a different computer. i'm surprised that i even have to say that.

On the other computer the program crashes :S

In that KDZ updater folder, there is another executable msi file I believe that you may need to install first.
LG Optimus G E971/3/5

Yup use the KDZ method to fix. If you're on rogers (e971) you need to get the kdz from
lg-phone-firmware.com then scroll down and download version 10d.
You can also download direct from LG if you can get the link.
This post links to the original NEW JB update http://forum.xda-developers.com/showthread.php?t=2196742
ALWAYS FLASH CUSTOM ROMS FROM 10D
Run the msxml.msi or get the microsoft xml pack from microsoft.
Run the LG Software from the website to install ADB access for windows.
Put your phone into download mode and run the KDZ updater program.
Wait. If you get a bootloop do a factory reset.
Better tutorials are available on here you just have to look around. This is where I got my info:
http://forum.xda-developers.com/showthread.php?t=2010624

I on the other hand have lost the ability to downgrade. Phone stuck on boot animation after first reboot during flashing with KDZ. I only have download mode available. Looks like from now on the MTP driver simply will not load. Sheesh.
Edit: I got Factory Reset option finally! All is good again. I really had to KDZ this thing like 30+ times.

Exact same thing happened to mine. After 5 days of literally trying everything I went to sprint and they replaced it with a new one.

[Q] Galaxy Note 2 i317 Won’t Boot After Update

Issue
1. Phone won’t boot beyond the Samsung Logo.
2. It won’t boot into recovery (download mode works).
3. Can flash rom using Odin but phone still won't boot.
Type of Phone
Type: AT&T Samsung Galaxy Note 2
Model: i317
Ownership: Bought in Nov 2012 brand new. Warranty is up but it is insured through AT&T.
History: Rooted and then un-rooted and returned to stock in January 2014.
Actions leading up to Issue
Updated to Samsung’s newest firmware Android 4.3 but didn’t like it. I rooted my phone and tried a custom rom but wasn’t happy. Un-rooted by flashing original stock rom via Odin 3.07. Worked great and I was back in business. But then the phone went through an update and never booted back up.
Detail
I’ve rooted all my other phones but never felt the need to root this one until I updated to Samsung’s new Android 4.3. I wasn’t happy with the decreased battery life and poor performance. So I used the method at http://forum.xda-developers.com/showthread.php?t=2004650 to root my phone using “root66_ATT_I317UCALJ2.tar.md5” with Odin 3.07 and it worked. I then tried a custom Cyanogen Mod rom but it still left something to be desired.
After more research I flashed the original stock rom “KIES_HOME_I317UCALJ2_I317ATTALJ2_215287_REV04_user_low_ship.tar.md5” via Odin 3.07 and my phone worked beautifully, at least for a day. Then I started getting the AT&T update window for Android 4.3 and the only way to get rid of it was to pull my battery. It was happening so much that I couldn’t even make a phone call. Out of pure frustration I decided to accept the update.
After the update installed it rebooted and never made it past the Samsung logo. So I figured I would just go into recovery and perform a factory reset as well as wipe the cache. The problem here is that it won’t boot into recovery. Only download mode works. I’m also seeing a red LED which I’ve read is a sign of SDS.
I’ve tried re-flashing the original stock rom again. Every time I do I get the green “Pass” display but my phone still won’t boot. The binary count is now at 21 since I’ve tried flashing so many times. I’ve been working on this and researching for 3 weeks. I’ve never had an issue that I couldn’t resolve when it comes to any of my past phones but this is beyond my skill or understanding. I also tried Samsung keys but it says my device is not supported.
Short of digging a hole in my back yard and burying it, is there anything I can do to fix this?
(Note) My wife has the same phone and also didn’t like the update so I flashed the same original stock rom to her phone via Odin and it has been working just fine. Only difference is I never rooted hers. I should have gone that route with mine.

Have you tried flashing, via Odin, just a custom recovery?
If that works, you may be able to follow this guide, starting at post #2.
http://forum.xda-developers.com/showthread.php?t=2618447
If that doesn't work, it is possible you have an emmc issue.... Your symptoms are similar to what others have reported here recently. You might be able to get a repair covered if you can get them to look past the custom counter ... You are running stock firmware... Maybe kies tripped the counter... Stranger things have happened...

Here's the link to TWRP (you want the Odin link toward the bottom):
http://teamw.in/project/twrp2/124
Here's the direct link to the latest philz cwm (you want the md5 file):
http://goo.im/devs/philz_touch/CWM_Advanced_Edition/t0lteatt
I prefer philz, but you will likely need TWRP to follow the dicksteele guide. You should also track down a CWM flashable recovery package for MH3 recovery to flash back should you need to return the phone for repairs. You can get this by following the i317 link in my sig.
If flashing this in Odin doesn't work that would tend to support the emmc fail scenario. (i.e. you flash it, Odin behaves as if it flashed ok, you power off, attempt to boot recovery with home-VolUp-power and it still doesn't boot). If it does boot recovery, you can try the guide as I mentioned before. Good luck!

I tried each of those just now and they both flashed fine however there is no change. I guess before I break out the shovel I'll try to see if AT&T will fix it since I do pay for the insurance. Thanks for the help that was good stuff. I wish it could have worked.

About needing a battery pull to remove pp note, I have been just reboot and it
Goes away until next data use/net access. When my 8 hrs is up I turn data on

another 8 hrs. Im sorry to hear they wore you down with the note- im going to

You flashed LJ2 Stock ROM from ODIN?
And you are back to the Samsung Logo that flashing/pulsing blue???
If so .....
Pull the battery and let the phone sit for a few seconds, pop the battery in and boot into stock recovery (HOLD VOL UP+HOME+POWER) and do a FACTORY RESET then reboot.
I had to do the same thing an hour ago....

I can't believed it worked. Flashed this and suddenly I have recovery. Then I re-flashed the original stock rom, did a reset and wiped the cache and I'm back up and running. Brilliant I say. Genius! Thank you for the great post and thanks everyone for your help. Seems like there should be a like button or something so that you get credit but I don't see one. This was my first time ever posting on any forum so I'm a little ignorant.

OUTSTANDING !!!
Glad you're back among the living.
This will get you back to 4.1.2
http://forum.xda-developers.com/showpost.php?p=49616718&postcount=2
EDIT:
I just did this and it worked perfectly .....
I'm actually doing that step right now also. I flashed back to stock testing the ATT update server.
EDIT #2:
At this step when the phone reboots the script will run. When it completes you want to boot to system. The next prompt will be do you want to install ROOT. If you do the swipe it will install ROOT, there is a DO NOT INSTALL button on the middle of the screen. Just a heads up, don't know if you are turning your phone back in or not now.
- Second step is:
You will need to download TWRP 2.6.3.1 and flash it in ODIN.
http://goo.im/devs/OpenRecovery/t0lt...lteatt.img.tar
This is necessary for an openrecovery script to run that is stored in the /cache directory from the update.
- Put your Note 2 in Download Mode.
- Open ODIN, put openrecovery-twrp-2.6.3.1-t0lteatt.img.tar in PDA slot. Click Start and let the phone reset.
- Your phone will reboot in TWRP. If not, pull battery and enter recovery mode boot into TWRP recovery (HOLD VOL UP+HOME+POWER). The script will run by itself.

sgh-i317 EFS seems like its gone
could anybody help me out with my note 2. ive tried just about everything i can think of. im getting pretty desperate. i can get everything to work fine (recovery,download mode,) but something is keeping it from booting up to the main screen, it will just hand at the boot animation, or the att logo. in twrp it tells me failed to mount efs. ive looked around in the file folders and its like it got wiped out? im not sure how though. could that be why its not booting up?
any ideas??

Nasty Bootloop after Flash on Sprint G2

Last night I installed geefree on my phone from the app store and used it to install TWRP. I downloaded a nightly CM11 and an appropriate gapps. Using geefree I rebooted to recovery (never figured out the button combination to boot to recovery "naturally") and installed both of the zips. This could be where I made my mistake, I installed both at the same time.
Now my phone loops, displaying the LG logo for a few seconds, then shutting off and rebooting before repeating the process. I can't seem to get it to go into download mode or the recovery menu. I've tried power+up, power+down, down+up and each of those while plugging the device in, etc. I can get the device to a hardware key control mode, though it doesn't seem too useful.
How can I save my phone? This forum has been a great resource in the past and I'm very grateful for the many tutorials I've followed rooting other devices. Hopefully you guys can save the day once again!

Volume up plus power is how to access recovery on sprint.
What stock sw version were you on before you flashed cm?
Did you wipe data before flashing?
Sent from my LG-LS970 using xda app-developers app

I was using stock 4.2.2, I believe. I didn't wipe the data (shame on me), a bad habit that I picked up from my first rooted device, the Samsung Moment. It didn't ever matter on that one, afaik. Thanks for the reply!
Edit: Volume up and power whether plugged in or not takes me to the hardware key control mode screen.
Second Edit: http://forum.xda-developers.com/showthread.php?t=2432476&page=35 I also found this thread where someone seems to be experiencing similar issues and they fix it with "LG Utility." Is that a PC application? It's a little vague to google, but I've been trying!

I have a bootloop issue every time i flash a rom i have to wipe all but sd flash roms and gapps the i do a restore from twrp and oly restore my boot image only and they boot no prob

I'm kind of starting to suspect my power button doesn't work at all for whatever reason. I have a lot of difficulty getting the phone to shut down, then it doesn't seem to easily power up. It's a strange collection of problems. Would a Sprint repair place be able to fix this?

If they have parts on hand if not either a swap out or a sendoff

Same problem here - bootloop and no download mode - CWM works! - urgently need help
I guess I have the same problem as InlineFourPower (apart from that my power-button has no problem).
I am stuck in bootloop since I tried to upgrade to Kitkat a few days ago. Now I can´t get into download mode any more, nor into fastboot or anything else. Only CWM works.
From within CWM I can successfully flash ROMs but that doesn´t help, since afterwards I am still stuck in bootloop. It is possible, however, to push files via adb-commands while I am in CWM.
Does anybody have an idea how to go from here or how to get download-mode back?

Device is recognized but can´t be mounted - bricked forever?

I tried a few things on Linux.
After terminal-command "ls /dev/sd*" when the device is unplugged from the computer I get "/dev/sda".
When the device is connected via USB, I get: "/dev/sda /dev/sdb"
So sdb is my LG G2.
So I went on to the next command: "gdisk -l /dev/sdb"
As a result I get: "Problem opening /dev/sdb for reading! Error is 123."
Does it mean that the phone isn´t mounted or what? Now I´ve connected my phone to another Linux machine with the same result. It is recognised (p.e. as sdd), but there is no sdd1. Seems as if it is recognized, but can´t be mounted. Does that mean my device is bricked for good? That´s it?

to get the phone into download mode you have to plug the usb cord in and hold VOL+, so to get this right as I have a case on mine, plug the usb into the phone first then hold VOL+ and plug into usb port on the computer.
it does take a loooong time to power down the phone with the button when stuck in a boot loop, just keep holding it until it shuts off, it will shut off eventually!!
plug the phone in while in download mode to install drivers and set com ports, then unplug before you begin your flash with LGFlashTool, hope this helps you out.

Thanks Cronic2009 for your advice.
There are, however, szenarios where download-mode is not accessible any more. Neither by using the hardware-keys, nor by using the adb-command.
After four days of resarch and a lot of trial and error, I finally unbricked my F320L using the two adb-commands outlined at the beginning of that thread: http://forum.xda-developers.com/showthread.php?t=2451696
Worked like a charm.
Thanks everyone for your advice.

no problem buddy, glad you got it figured out, good luck to you from here on out!
FYI, that link doesn't work
I just wanted to ask anyone who might know, since the bootloader of the LS980 is locked, we cannot "break" this correct, so no matter what commands we decide to run through root, we cant touch the true bootloader there for LS980 fail safe? (Besides Acts of God, EMP, ect)

Thanks for letting me know. I corrected the link in my previous post.

Be sure if you use a aosp based rom to flash the ZV8 modem. Your can use dr87 or furnance kernals after you flash the zva modem althought i have encountered soft brick due to this.

so i'm having this exact issue and i don't know how to get out of it. i just need to transfer the radio to my phone somehow but nothing shows up under adb devices. i'm trying to the lg mobile support tool now. its downloading the software. but if it doesn't work does any one have any fixes?

After using tot and flash tool to get back to stock, did you try going into stock recovery and do a factory data reset? I know it sounds stupid especially after a tot but try it. Couldn't hurt

Borderline noob here, so please bear with me...
I have been using TWRP 2.7.0.0 to do all my work, and I was able to get the Lego ROM installed with ZVA. I got into too big of a hurry and forgot to make a backup of stock. I've also been unsuccessful in trying to install ZVC modem and firmware. Thankfully ZVA works as does the LEGO ROM, but I'd like to have stock there to access as well. The stockZVC that's on the Android Development page has been getting stuck (bootloop?) on the Sprint Spark logo. I've done TWRP's factory reset with no success. Any help would be great.
Thanks in advance!

Yes sir I've tried that and more to no avail is there anything I can do through adb I'm on stock recovery phone doesn't stay on long enough to install anything

You ever get her fixed?

Anyone have a boot loop issue?

Earlier this evening, after texting a friend, my phone rebooted itself.
It appears to be in a boot loop. It will only reboot into rebooting. Never loads Android. I pulled the battery, let it sit for a few minutes, and tried again with no results.
I've not done modding to the phone (mainly because its locked), and will be returning it to my local AT&T store tomorrow. Thankfully I have insurance on my phone, so I shouldn't have an issue getting a new one.
Anybody else had this issue, however? It's really strange.

Read a guide on flashing back to stock. Use ODiN and flash the stock file of your choice in the ATT note 4 forum from Download mode. Google how to boot into download mode. Hold those buttons until phone powers off then keep holding until you see download mode. You will need to install samsung drivers and for ODiN on Windows go to Devices coms and ports and change port to 3 in advanced tab.

I updated my post to add in a missing word. I havn't done any modding. I do not intend to do any flashing to the device.
I'll be returning it to AT&T tomorrow and getting a new one. My question was if anyone has had this issue before. Thanks for your response. Unfortunately, does not address my question.

I have had my share of boot looping experiences, never from not doing any type of experiments with my devices. nonetheless myself and I'm sure many other people just do what was mentioned in the quote to alleviate that problem.
i know you (OP) mentioned you don't plan on doing any flashing, but i would do that before using insurance personally, even if there was no deductible

This process is not dangerous if your phone is in a bootloop. Hell AT&T or whatever carrier probably does this themselves if a phone is in this kind of situation. If not rooted or any mods you will still have OTA updates. If you are worried about carrier recognizing if you modded it or something and they wont take it back dont worry just flash it using ODiN. I've rooted many devices hacked compiled roms flashed them and kernels s-offed etc. You can always get back to stock remove flags and your carrier will take it back no matter what just dont return a device with the actual mods on it.

Why not just try to reset the device from the recovery menu? If it's a stock phone it should fix the bootloop.

It won't fix what sounds like a missing or corrupted boot file, had to deal with it on a LG g3.. restoring a full back up or a plain reset had no effect.. it was either doing a full flash or flashing the boot files
for that phone it would randomly happen when the OTA tried to upgrade the device while it was rooted, took me 3 times of dealing with it before I realized OTA was still live

Small update. My local AT&T store has a replacement being sent to me. I'm unhappy, however, since its apparently a refurbished device. I pay for insurance that covers a new device if something, anything, happens. They're refusing to send me a new one for some reason that they won't explicitly state to me.
My loyalty with AT&T has wavered, and I will probably be on another network in coming months. I'm thinking Sprint so that I can least have an unlocked Note 4.
Regardless, since this device is being sent back, I decided to try and Odin flash it anyways. It did not work. Still boot loops at the Note 4/Android screen. Doesn't even load the AT&T logo. I'm fairly certain something is fundamentally broken with the device. Probably a factory error. It's never been dropped, and has been inside a hard case since day one.
Being that it is a manufacturing error, I'm not to angry about that. These things do happen. AT&T's treatment of me, however, is just unacceptable. I've been a customer for about eight years, and have been on Android since the Motorola Backflip. I upgraded to a Samsung Captivate and never looked at another manufacturor.

Are you able boot to the recovery menu?

Try downloading one of sunderwares stock firmwares in a newer 3.10 odin after extracting the zip with contained files. I recommend latest OC4 just re flash it a different one or try again
