Did I just BRICK my G Nexus?

So, last night I was out and about - just having a good time. Noticed that the battery on my GSM Galaxy Nexus was getting low. Went "Meh, wasn't the first time it's died." It got to 1% battery power and shut-off, like it normally does. Me being who I am, I turned it back on to see just how much more juice I could get out of it.
Phone booted up alright. Finished the boot animation, and then a couple seconds later turned off.. not a big deal. I get home, plug it in, and the charge screens cycle..... and then they cycle again. And again. And again. Basically just looping. I turn the phone ON, finishes the boot animation and... turns off again riight away? Goes back to the charge screen loop.
I'm not talking about the regular charge screen. After the battery gets 'filled' twice, it completely restarts. Black screen for 2 or so seconds, and then it goes through the charge animations as it would if you had just pluggied it in. I CAN get into bootloader, but that's about it. I'm just curious.. has anyone seen this before? Or know what my problem might be?
I'm unable to turn USB Debugging on in the system settings, so I'm at a loss as to how I can fix this issue WITHOUT bringing it into Bell.

Try going into recovery and wiping cache and dalvik. If that doesn't work reflash your rom

My phone is completely stock (I reflashed it to to the stock yakju? I believe it was when I found out Samsung had screwed people off the google update path.. so I can't get into recovery mode. It just shows the broken android. It's all been re-locked, and since then, my laptop has died. So I no longer have the ABD/Samsung drivers setup. Which was a pain to get going the first time..

The "Broken android" IS stock recovery. I believe that when you push Volume Up seeing that image it takes you to the stock recovery menu. But you can always reflash Yakju or any other ROM through fastboot mode (see the tutorials here on the forum).

Turn it off. Leave it charging for a few hours before turning it on.

You do not need to have USB debugging enabled to use fastboot.

It doesn't take long at all to install the drivers. Look for a thread with "universal" in the title. I think it is in GN General. Once you do install the fastboot driver, download the fastboot.exe file and reflash the stock ROM.

The problem I have is that the charge animation doesn't change... i.e. It'll constantly refill the battery and all, but it always starts from the bottom (While when a phone is say... half charged, the little battery is half filled and the animation continues.
I'm not sure it's even charging at all.

Update time!
Got it into the stock recovery. Wiped the cache and all of my data. Rebooted, and.... it turns on! No longer reboots on regular startup. That's the good news. So at least it's somewhat useable now..
Now for the BAD news.
-It still does that retarded charging bootloop that doesn't seem to get me anywhere
-....When it's on. Like, running, it doesn't charge. Nadda. Zip. Zilch. Computer, wall charger, android dock, nothing. It just won't charge when it's on. However when I got it to power on, it said I had 14% remaining - which means it was likely charging inside the Bootloader, as I had it on that for quite a bit.
I think this just went from a software to a hardware issue. Thoughts?

Power down phone, do a long battery pull, place it inside again, let it charge for a few hours without powering it on, when it is fully charged (or after a few hours) pull battery again and then take charger out the phone. After a few minutes, place battery inside phone again and start it up without the charger.
Hope that works.

And that might fix this charging bootloop? Because the LCD doesn't even turn off..

You could always try a new battery

+1 for the new battery thought.

Battery test
I am having a similar problem, I get the boot loop.
Difference is that I had started with a new battery so that could be your problem or unrelated. I went to a mobile shop yesterday and they let me use a new battery to see if the loop would start. It did not so there seems to be at least one other failure path. I have avoided a factory reset as I was hoping to pull some pictures but coming to the realization that I will have to try factory reset as a last resort
I posted to this thread #192
http://forum.xda-developers.com/showthread.php?t=1490815
My Galaxy Nexus phone from WIND went into a reboot loop yesterday. It had been charged to 98%, used to make a call and then put away. Wireless was enabled. Noticed vibration periodically and say it was rebooting every 6 - 7 seconds. Pulled battery to stop reboot. Saw references to fully charged battery via USB stops reboot loop so tried that. Battery voltage was 4.17V and still went into reboot loop.
Tried to boot into safe mode but still goes into a loop
I went into recovery mode and tried all options but factory reset because I am hoping to recover some pictures
reboot system now
apply update from cache (but did not have an update to install as only options were ../ lost+found/ recovery and when I selected these was in a loop as well)
wipe cache partition
Can't tell what version of Andorid I have as the phone never finishes booting.
Boot console gives the following information
Product Name – tuna
Variant – maguro
HW version – 9
Bootloader version – PRIMEKK14
Baseband version – I9250UGKL1
Have installed SMS backup because I was planning to do a backup after a trip. Also have two GPS tracker apps installed.

If you can boot into recovery, you may be able to get your pictures off your device.
1) Make sure you have the drivers for your device properly installed on your computer.
2) Download the attachment and unzip it to a directory on your computer.
3) Open a command prompt in the same directory.
4) Reboot your device into recovery and plug into your computer.
5) Make sure your computer sees your device by typing: adb devices
6) Pull the data off your device by typing: adb pull /data/media
Note: depending on how much data you had on /sdcard, this could take a while, so be patient.

[Q] Galaxy note II bootloop problem. worst i have faced!

Hey guys....im new on xda i had a problem. recently my phones in a bootloop.i did not drop it or try to flash a custom rom. it was in a bag for 2 hours after which it just starts up to the white logo and not even the animated one and keeps repeating that. i have tried pulling out the battery for long times and letting the charge drain out thing but in vain. worst part is i caannot get into recovery or donwload mode. download mode flashes for a few seconds but just reboots. recovery mode doesnt work at all. i however managed to boot into download mode. once the download mode warning appeared i pulled out the battery with the usb cable in it. but thats as far as i got. i cannot flash a rom on to it either becasue it needs to restart i guess and wihtout a battery thats not possible..........i thought of trying out cwm becasue that had usb debugging turned on as default and then using abd command line to retrieve my data but for that i need to get into download mode. even checked out the power button problem but the button was fine.....im running out of options....my phone is not rooted.....any suggestions guys?....really need help saved up a lot to buy this :crying::crying:

Your battery is faulty. All those things you mentioned are signs of a dyeing battery. Get it replaced or borrow a battery from your friend to check it out.

[Q] My Phone wont boot up! HELP

Problem SOLVED!
Thank you all!

Hi ClarkOwen, would you care to share what happened and how to solve it? My Optimus G won't boot with red flashing led.

What rom are you using?
I tried to boot into safemode by turning on with power button + volume down button and holding it till it boot up then I uninstalled framework and gravity box as i think they are preventing my phone to boot up and then I rebooted my phone and it worked
What exactly did you do with your phone? What caused it not to boot up anymore?

There are senarios where you do get to restoer your phone using kdz but then it still wont boot up with red led blinking which basically means the battery needs to be hardware reset - taken out of the phone which would require you to open up your phone which is difficult. Thats why I need to know first what happened which prevents your phone to boot up.

Thanks for your reply. I run stock ROM and was preparing for flashing with CM11. I installed ROM Manager and updated my clockmodwork recovery. Then I boot to recovery when this disaster began. The phone just wont boot.
I followed the instruction found in this forum to unbrick using kdz updater and LGNPST and yes I needed to disconnect the battery first. Open up the battery cover was difficult but I managed to to it. After numerous attempts I managed to complete the step for both kdz updater and LGNPST but that still wouldn't boot the phone. Not even into recovery. I could get to the download mode though.
The last successful attempt with KDZ updater (successful means completed steps) has caused my phone totally dead. Now it won't respond in anyway. No flashing led, nothing. I suspect the battery could be dead.
Is it true that we can't charge the battery when the phone is (soft)-bricked?
Anyone knows how to charge LG Optimus G battery in the case of emergency? Ie. not through the phone? I read post about charging using stripped-out USB cable but I don't know where is the +/- of the battery.

[Q] Boot loop then restore upgrade error fail

Here's what happened to my (not rooted) G3
The phone has been weird for a couple of days, rebooting randomly once in a while, but working fine whenever plugged onto a power source. Google told me it could be a battery related issue, so I bought a new battery online (and I didn't get it yet).
This morning the phone entered a boot loop, even when plugged in to any power source. Google this time told me I could put the phone in "download mode", then restore upgrade errors via LG PC Suite. I try to do that, and the phone actually goes into download mode, but I'm not able to restore upgrade errors with that ugly piece of software because it keeps "losing" my phone usb connection. I unplug and plug it back in several times, the phone seems to make progress on the firmware upgrade screen but I see a red ASSERT error on my phone at around 15% of recovery.
Now whenever I turn on my phone and try to put it on download mode keeping the volume up button pressed, the screen will just go straight into firmware update, warning me not to unplug the usb connection, even if the phone isn't plugged. I'm able to start a restore but again the usb issue comes up and the phone is totally frozen and stuck to that firmware update screen. If I want to turn it off I need to remove the battery.
I'm doing this because I would love to recover some data from my phone, otherwise I would have done a hard reset or a flash of some kind
Please someone help me before i throw this piece of junk out of the window

Nobody able to help me in any way?

bump =(

Contact LG in this case. Might be faulty NAND memory. If it is then it will probably be impossible to get those files back...but they will replace it and fix the phone. (if it is under warranty that is...)
BTW if you take out the battery during flashing...you may hard brick the phone...then you're technically more fked

D855 Stuck in Bootloop-- Light Sensor and Vibration Still Work

I'm having a weird problem. Yesterday I was using my phone as I normally do-- texting, playing simple puzzle games, etc.-- when I noticed the battery was at about 2%. I wasn't very concerned so I tried to send one last text before it died. Shortly afterward it died with the usual "Powering Down" alert. I thought absolutely nothing of it and once I had access to a charger, I did what I normally do: I turn on my phone, wait for it to get past the LG splash screen, and I plug it in once it gets to the boot animation. I do this so my phone will turn on instead of going into charge only mode. Also, like usual, my phone's screen dimmed seconds after the boot animation began (I assume from my automatic light sensor settings), and I could feel it vibrating a little (also something it typically does upon boot).
However this is as far as it got. I was very confused when about an hour later, the phone still hadn't completed boot. I removed the battery, inserted it again, and tried once more telling myself that I would wait as long as I could instead of just an hour. Booting the second time gave me identical results-- everything is normal (light sensor response and vibration indicating the phone is powering on) yet it gets stuck. The only difference is that this time I got to see the entire bootloop.
After the boot animation screen has run for a while, I get the usual "Android is starting.... Optimizing app ## of ##" (#= actual numbers). Once it finishes, instead of booting my phone, it begins the boot animation again. If left alone it will cycle between the boot animation and the "Android is Starting" screen indefinitely.
TL;DR:
1. ) Caught in bootloop between boot animation screen and "Android is Starting... Optimizing app ## of ##" screen.
2. ) The screen still dims and there are little vibrations that usually tell me the phone is about to turn on.
I have tried:
- a hard reset- this yields only a slightly stronger vibration and it starts the bootloop again.
- Download mode- this does the same as the hard reset
- Removing battery for a while- no results
- Full charge to completely dead to full charge again on charge only mode- no results
I am running CM13 Nightlies from late February (not completely sure which exact date). Which I flashed without issue about a month ago. I do have Xposed and run various modules, but I was using nothing at the time and hadn't for about a month. My computer recognizes my phone as an LG G3 Device, but refuses to access any files.
Any help would be greatly appreciated!!

Phone not starting.
First remove phone battery, insert it again, do not start phone. Connect your phone to original charger and charge it, while charging with the charger start your phone. Your phone should start if yes/no report me immediately. Your phone battery is failing to start your phone (Due to Low Voltage in battery). Replace with original battery.

Alright, I removed the battery, reinserted it (without turning the phone on) plugged it into the wall charger (seeing the charge only battery animation), and attempted to turn it on. Whenever I try to turn my phone on after plugging it in, I get the LG splash screen followed by the battery charging animation. It never reaches the boot animation. I'll let it charge for a while and try again.
Thank you for the advice!

Okay, I let the phone charge completely and attempted to turn it on whilst plugged into the wall charger again. Unfortunately I had the same issue. The phone shows the LG splash screen and then the battery charging animation again-- no boot animation.

Yeah, I'm trying to avoid a full reflash/data wipe. Since I haven't messed around with any Xposed modules or root apps, I also haven't backed up anything for quite a while. No abnormal apps were running before the battery died, which leads me to believe this can be solved somehow without a full wipe.
Also, I tried to use my boyfriend's battery to boot up my phone. I thought it might be a bad battery-- as some people on-line have mentioned. Unfortunately, it still refused to boot and it produced the same bootloop.

You see , if and not and this and that dont help . te only way to save files is to get acces by recovery or boot, you cant boot but possible you have recovery so start saving your files you need. when you have or dont have your files . you stil need your system to boot for that to happen, it needs to work. so flashing a default rom with wipe sould work if it doesnt you flash original if that doesnt work its dead

I think I forgot to mention, I cannot access recovery mode. I have the latest TWRP installed, but attempting to boot into recovery gives me the same results-- endless bootanimation/ "Android is Starting" bootloop.

So no acces at all . so what do you do ? Read above! Anyway good luck

Solved
I fixed my problem. It turns out I was being an idiot and got the method of entering recovery mode on the LG G3 confused with my Samsung tablet. I should be able to fix the bootloop on my own now. Thanks everyone for your help! Cheers to idiocy.

Hey, I have the exact same issue right now. Did you solve your problem, and how? I tried removing the battery and charging with original charger to 100%. I connected it to my PC, went into Download mode and clicked "Restore Upgrade Errors" in LG PC Suite. It successfully flashed the firmware update, then it said "Android is starting.... Optimizing app ## of ##". But after that it restarted into bootlop again. Also I noticed that sometimes it vibrates, and my LED (light sensor) doesn't light up anymore.
Any advice? I haven't tried replacing the battery yet.
