[Q] Galaxy Nexus won't turn on after attempting a flash stock + Unroot???

So I'm not sure what happened with my girlfriend's Gnex, she updated to 4.2 a couple days ago, then her battery died. So she went to charge it and when it finished charging, she went to turn it on normally, but it went into a reboot loop? So i was talking to someone else on another thread that i saw similar, so i tried to do a flash stock + unroot, it connected i got into recovery menu and everything, went to do it, and then the screen started going staticy, and it said it failed then it said it should take 5-10 minutes or something. So i guess it froze or something, so i took the battery out and the screen was still staticy, and then i unplugged it from the USB, and now it won't turn back on. Did i brick the device? :/ Thanks in advance for future answers.

you cant get into to recovery either? or fastboot mode?

nope, when i went into recovery it went staticy again and then went back into its bootloop :/
but now it just won't turn at all, i've done a battery pull, battery swap, nothing worked.

I'm having a similar issue. I wanted to flash the memory so i relocked the phone using the wugkit, then unlocked and rooted. For some reason, it wouldn't load a new rom. I kept getting the triangle exclamation point android graphic. I pulled the battery and that was it. Black screen. Won't turn on. A cpl of times, it was almost recognized by the computer via USB, but just kept failing. This sucks.

just a thought: are you sure it's charged up enough to boot? i know i've mistakenly thought my phone was messed up when the battery was just dead

Yes the battery is charged. Occassionally, when I plug it into the computer, it makes the new device notification and then fails over and over again. I keep trying to get a glimpse of a lock so i can adb it.

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.

just start with a full reflash , if it doesnt boot up its simply broken

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.

Please help!

Can you access recovery?

updated below

not even the stock recovery?

I can access stock recovery only when the phone is plugged into the charger
Will not work if the phone is plugged into the computer via usb

I'm guessing this means you have a faulty battery. The fact that it works on the charger and not unplugged or plugged in via USB is indicative the phone believes the battery is completely drained.
I would try to following before contacting Amazon for a warranty replacement: Try to factory reset from the Amazon Stock Recovery (assuming you're certain you are on FireOS). I would then let it charge turned off for a couple hours and try to turn on. If it works, great. If not, I'm afraid working with Amazon is your only avenue.

Any update on the case? I had the same situation. My fire phone having endless bootloop. Only if I connect to charger it can work.
Manage to go to recovery, wipe all, problem still persist.

Same thing
Went into stock recovery
Wipe the phone clean and it still gives me the endless loop

Anyone got an fixes for this? How can I pull all my pics off if this if it keeps rebooting

bump for help

Try to charge your phone and turn it on. If can, you can use WiFi file explorer from play store to pull your data. Make sure fire phone and pc or laptop connect to the same WiFi.
Mine will goes to bootloop if direct connect to pc or laptop.

I just started having this problem yesterday, same exact symptoms. Wiping cache took an incredibly long time, factory reset went smoothly, but neither fixed the issue. It went in to another boot loop immediately after the reset completed, and only came out if it when I plugged it in to a charger again.
That said, it told me a little later that it had updated its firmware, congrats yada yada... and so far (fingers crossed) it hasn't acted up again.
It's now on Fire OS 4.6.6.1 (466001420), I couldn't say what it was before. Can anyone still experiencing this report what version you are on right now?
Also, it may or may not be relevant that I allowed the phone to charge for over 12 hours before disconnecting it.

Have you tried booting into stock recovery then pushing amazon update file to the phone via adb (adb sideload)?

Is it possible do to update you fix your issue? I had charge my phone for more than 12 hours but no luck...
I will try to update via sideload adb. If anyone can show me the link for the how to appreciate it.

Update on mine:
The firmware update did not fix the problem. It is still possible that it alleviated the situation for a time, but much more likely it was just coincidental timing.
My Fire Phone behaved itself for most of a day and a half, then suddenly went back to the boot loop. I left it this way overnight to try to deep cycle the battery.
After draining completely, it took several hours on the charger before it began showing a charging screen, which comes and goes in intervals just like the Amazon logo had before. It has not progressed beyond 0% charge since then. I'm assuming a faulty battery at this point, or perhaps a corrupt battery stats file (but that should have cleared with the factory reset correct?)
My sincere apologies for any false hopes I may have given anyone.

+1 for this.
I had this problem and just replaced battery. Fire Phone worked great again !
Can't believe a. faulty battery cause many problems.
Btw, if you replace battery by yourself, please notice the attached glue between battery and case. Try to remove them all gently - can search on YouTube how to replace Fire phone battery.

VS985 died?

Yesterday I was using my LG G3 as normal and I set it down for a little bit. When I picked it back up, the phone wouldn't turn on or even go to a battery dead screen I took the battery out and tried again but it still didn't work. I tried to charge it for a while, but it didn't even go to a battery charging screen. I replaced the battery and it did turn on for a little bit, but it just went into a bootloop. I was able to get it to recovery, but nothing worked. I tried factory resetting it, clearing the cache, booting it to safe mode, and USB debugging all to no avail. I've never even tried to root this phone because I wanted it to be stable. Is my phone dead or is it able to be saved? If it is dead, what happened?

Try reflashing your stock ROM with this method.

You need to burn the emmc with a hair drayer, I fixed my G3 with this méthode.

LG G3 D855 blackscreen right after booting logo

Okay, so i have an LG G3 D855, few months ago it worked like a charm.. But then shortly after i started noticing random reboots everytime during using apps. Then it went in bootloop. I tried to turn it on again, entered recovery screen, choosed factory reset and it did, but then it went through the same process, random restart. Eventually stuck up in factory resetting screen. However i think i made mistake when the phone freezed in reset screen : pulling out the battery. later it lost its IMEI & kept heating up (probably tried to find its cellular framework of some sort).
Days passed, several factory resets has been done. Now the phone's at its worst state. It refused to get past the boot logo. everytime it finishes booting, the display just goes black, tried to plug usb charger, chargin indicator doesn't want to turn on, neither after i pulled out the battery. I have to leave it a few days to get it working again, but it keeps persisting.
Addition : The phone's also feels warm post the blackscreen.
Any thoughts whether can this be fixed or i have to replace something inside the phone's board?
thanks in advance.

Reflash with lgup.

Remove the SIM card and the memory card. try again. Full wipe system data ...
I've had the same problem. I've tried. Worked
found the problem. memory card

EDIT: Some kind of voodoo happened right now! I was about to unbrick again and wanted to give the phone a try to boot before. And it did! So no problem at the moment, but still a strong feeling of uncertainty...
EDIT: Phone is still randomly rebooting and gets stuck in bootloops
-----
Hej guys, I really need your advice,
but first things first: Thank you very much for all of your wonderful work on custom roms and further support of older devices. I've been reading here for a few years now and was more or less happy to have up-to-date-roms for some of my phones.
Now I'm facing quite the same problem like OP did / does. Everything started with me, following this guide to root my D855 (coming from stock rom) and flash TWRP: you tube.com/watch?v=8VOgM3jLas4 (Note: The guide told me to flash "3__HacerPermisivo.zip" for updating the kernel, which I did.)
Next, I flashed a newer version of TWRP ("twrp-3.2.3-0-d855.img") than the one provided in "2__AutoRecMMD855.apk" by the guide above. I wiped dalvik and cache and after that, I flashed "lineage-15.1-20190410-nightly-d855-signed.zip", wiped dalvik and cache again and flashed "open_gapps-arm-8.1-pico-20190411.zip". I wiped dalvik and cache again and told TWRP to reboot.
Here is, where problems began to occur. The phone got into a bootloop, showing up the LG splash screen again and again instead of booting into LOS correctly and set it up. At some point I decided to remove the battery. When I did, at the same time LOS was just going to load, which I saw because of its beginning boot animation. So I screwed it up right at the wrong moment, I guess.
From here, the phone bootlooped every time, I wanted it to start. No battery acrobatics helped and on top I couldn't get it into recovery mode. Any attempts ended in bootloops. I think, this might be what is called a brick / to brick your device, isn't it? I found this guide to unbrick a D855 and followed its steps: open -freax.fr/guide-unbrick-your-lg-g3/
Believe me, it was a real pain in the ass! Because of me, messing up something or the phone getting stuck into a bootloop during the unbrick process, I had to do it 4 to 5 times until success... I have to say: I didn't follow the last steps beginning from "Root". Instead, I followed the guide from the beginning of my post.
Finally, I got "lineage-15.1-20190410-nightly-d855-signed.zip" and "open_gapps-arm-8.1-pico-20190411.zip" to run. I set it up and began to load some of my apps of my Play Store collection. While downloading, the phone froze, crashed and began to bootloop, from here unable to boot normally or to get into recovery mode. So I unbricked and flashed again (again several times because of bootloops before LOS first set up). When I got it to work again, I was able to install my apps without being trolled by the phone again. But scrolling through the eBay app froze the phone and it began bootlooping again...
You can believe me, I was about to throw the D855 against the hardest piece of wall, I could possibly find in my rage. The reason why I didn't give up at this point is, that I LOS-rommed two other D855s just a few days before. Those were my mom's and my girlfriend's and they work fine until today. I bought this third one for myself, because I was impressed, how good LOS worked on the D855s. On top I wanted to get rid of my Samsung Galaxy S4 (GT-I9515), because LOS kinda sucks on it, but this is another story...
So I figuered that the earlier LOS version I used for the women's phones, could solve the problem. So I unbricked again and flashed "lineage-15.1-20190327-nightly-d855-signed.zip" and "open_gapps-arm-8.1-pico-20190329.zip". And hell yeah, that did work! No bootloops, eBay worked fine, just everything was as I loved it on the other phones, I flashed. Until tonight. I've been lucky for almost two days, but tonight this happened: I plotted a route in Google Maps and saved it as a shortcut on my homescreen. I closed Maps and tapped the route icon. Freeze - crash - bootloop - no recovery mode! I wanted to start crying, because Maps has already worked fine yesterday. And it still does on the other two phones, which run exactly the same rom...
So now, I'm sitting here, not knowing what can be done further. I'm not a programmer / developper or any of those cracks providing us the newest software for old phones. So I just can do wild guesses. Maybe the moment I removed the battery the very first time after flashing messed something up very deep inside the phones internals and it can not be cured any more. Maybe some of you guys have experienced similar things and know a tweak or a simple step, I forgot. Anyway, I hope I can use my phone on LOS some day which I bought especially for this case.
Keep up the great work, folks!

I ordered a new mainboard. It should arrive within 3 weeks. I'll keep you updated.
