Nexus not booting after system upgrade

Hi. I am a newbie on the forum so pardon me if I have posted in the wrong section.
I have a Samsung Galaxy Nexus i9250 that I purchased under a 3 year agreement with Bell not too long ago, perhaps in May. One day I left my phone connected to my PC so I could transfer some video and picture files that were on there. After the transfer finished, I then proceeded to remove my Nexus from my PC. After a while, I noticed it restarted because the screen went blank and I heard it vibrate because it was on my desk.
My phone is encrypted, so when the phone restarts, or you turn the phone off, and on again, you need to enter a PIN to decrypt the storage. When I entered the PIN, the Nexus froze and then restarted, leading me to the exact same screen I was at previously. Now, I attempted to enter the boot-loader and go into recovery mode, but each time I went into recovery mode, the phone restarted normally. There were a few times I would see the android guy with what looks like a globe sticking out of his chest and a bar below him which probably meant recovery, but my screen would flash back and forth and eventually stick.
I took the phone in only to be told that the system image in the Nexus is corrupted and that it wouldn't be covered under the warranty. At that same time, I decided to go back home and see if I could work with anything. I attempted to use ODIN to put ICS 4.0.4 back on the Nexus, but in between the process, ODIN failed, and now I am left with a phone that can not turn on, go into recovery, or anything else it should.
I'm at a loss here and I'm wondering if anyone else would have any suggestions at this point. If I have to send it in, I'm okay with that, but if there is something that can be done from my PC, I would like to attempt that first. Thank you for your help.

Does anyone think they may have a solution?

Give this a try if it is truly bricked. Apparently it works wonders though I'm not sure if it will work in your case.

Thank you so much for your help. By using that program, I was able to boot back into ODIN mode and upload ICS 4.0.4 back on it!

[Q] Nexus 7 suddenly bricked ?

Hello all, so yesterday I went on my tablet (Nexus 7 2013 WIFI ver.) and browsed the net a bit and went to sleep. I recall having around 30% battery power. This morning I wake up to an apparently flat battery (power button didn't turn on anything) so I just plugged it in and did something else. After a while, I took my tablet and started it with the power button. However, it got stuck on the Google logo and never fired up anything. I've rooted the tablet quite some time ago (months) so the cause is not from there.
Things I haven't recently done:
Installing an app.
Rooting or flashing anything.
Updating an app.
Things I have tried doing to fix the problem:
Booting into FASTBOOT then trying the recovery mode = still stuck on the Google logo.
Booting a custom recovery image using Wug's toolkit = frozen at the team logo (TWRP) / black screen (CWM).
Flash Stock + Unroot (Soft-Bricked/Bootloop) = FAILED (flash write failure).
So now I'm really stuck and desperate to make the device work again. I've been reading all day long and trying all sorts of solutions to no avail. And it seems far-fetched to me for a device like this to just instantly brick itself without any reason at all.
Can anyone help me with this case ? Or does anyone has any idea what just happened to my tablet ? :crying:
EDIT: I'm afraid that warranty might not work as the device was unlocked and rooted so it's the last solution for me.

Bumpity bump
No one has any idea what happened to the tablet and how to fix it ? I've tried doing some more flashing but to no avail. It just refuses to flash and keeps failing to write the files.

I think you need to leave out on the charger for 1/2hr without doing anything with it. You are probably using what little power it has charged by trying to reboot it, etc.
I had to do that once and it did the trick.

There is no reason you should not be able to get in to recovery (power and volume down).
You could call Motorola. They have good tech support.

The exact same thing happened to me. I rooted it months ago and haven't changed a thing since then. It just froze up a few days ago. I restarted and it just gets stuck on the google screen. I can get into the bootloader, but when I try to go to recovery, the google screen comes up and won't go away. I've tried every method I can find for flashing the stock image and absolutely nothing is working. I just get stuck on the google screen.
Please update this if you find a solution!

Do u guys have the most up to date version of whatever particular recovery that you're on?

Yep. I've flashed the stock recovery multiple times to no avail. :/

If you can't get into recovery or flash any images it sounds to me like a hardware failure. Bad memory maybe? If you've tried everything then RMA to Asus before the one year warranty runs out.
Have you tried to see if your computer sees your N7 by typing fastboot devices if you have the sdk installed?

I was to slow with my update. Does your computer see your N7 with fastboot?

Yes, I can get into the bootloader just fine and I can use fastboot. I go through the flashing process and the command prompt says everything flashed successfully, but when I restart the device, it hangs on the google logo. The same thing happens when I try to boot into recovery.

If you fastboot flashed the factory image and can't boot up then it sounds like a hardware problem. Out of ideas, sorry.

I'm not sure what happened, but I just ran this little utility again (I've done it many times over the last week or so to no avail) and it actually worked. Hopefully it keeps working!
Thanks for your help!

HELP: Can't boot/enter recovery

Hi all, hopefully someone can help, I was using my phone fine earlier when all of a sudden it just switched off, wouldn't turn back on at all. After trying for a while I've gotten into fastboot. I've tried booting into recovery but no luck.
I've since tried wiping cache - no effect. Flashing recovery - 'FAILED (remote: image update error)'. Boot recovery image - reports success, does nothing.
I'm S-ON, was on a custom ROM. Anyone offer any advice?
Thanks.

Also, the phone doesn't seem to stay turned off now, keeps booting itself into fastboot.

What the model of the phone

It's a UK One M8.

After a couple of hours of messing around with no luck it's now just turned on. No idea what that was about. Afraid to turn it off now!
If anyone sees this and does have advice I'd still appreciate it, feel like I'm probably on borrowed time...

have you had custom rom, recovery or root installed before?

I've only had this phone a month or so, rooted it pretty much straight away and installed Viper ROM. Left it alone since then waiting for Lollipop.
If you just mean experience wise, I've rooted all my phones for years, never had one randomly turn off for no reason and refuse to enter recovery though (thankfully), usually when I have issues its cos I did something daft!

Half way through Christmas day the phone froze up, completely unresponsive. Once the battery had died and I could turn it on again I was back to where I was, can't boot up, can't get to recovery, fastboot won't flash a new recovery, get the same failed message as last time.
Anyone got any ideas?

Thanks clsA. I'll take a look at the link...
The phone started working again late last night though, again no reason, just did. I took the opportunity to update the recovery, do a full wipe and install a new ROM. Hopefully I won't see the same issue again, if I do I'll try out that fix.
Thanks!

Random bootloop, Can't find a fix

Good morning guys,
Last night, i was just using my phone like normal when it froze, crashed, and began to bootloop.
I've tried battery pulls, I've tried to factory reset using the volume down + power combo, I've tried to wipe cache and enter safe mode but none of this worked
I was on 10b firmware but since none of the above worked, I tried to KDZ to a stock 11a which still keeps my phone at a bootloop. All I see if the LG logo at startup and a crash.
do you have any suggestions on how I can try to fix this? according to reddit this random bootloop has been happening to multiple people
thanks in advance for your help

It started happening to me, as well, over the weekend. My phone crashed and started bootlooping, stuck at the LG startup screen where it stalls for a few seconds and then goes black. Every now and then it will boot up properly, but the phone crashes after about two minutes and starts bootlooping again. I cannot manage to wipe the phone because it so seldom boots properly. I noticed that the phone gets very hot. I suppose that I will need to return it to Verizon for warranty replacement, but I hate having so much data on the phone when I return it. I was doing nothing unusual with the phone when this started happening.

yeah it's definitely weird. I was rooted on 10b holding out for a bootloader exploit down the line.
I called up verizon and theyre shipping me a new g4 since it was still under the 1 year warranty. I hope it's still rootable with the firmware it'll ship with

Same here
Hey guys! I thought I'd reply instead of making a new post because I think I'm in the same boat. My dads phone has just started doing this, but the weird thing is he wasn't rooted! I was able to get it to the recovery and tried the wipe cache and safe mode options, it didn't do anything.. I then tried flashing the kdz but no luck..
Hope some of the smart folks here can help us!

I was fortunate to get it into download mode so I kdz it back to 11a stock so as to wipe all data, thankfully. The stock reset made no difference, as it still would rarely boot, and even when it did boot it would crash fairy quickly. My warranty replacement should arrive tomorrow.

yup, i kdzed up to 11a and it went from modified status to official so hopefully that wiped everything on my phone too. My new one will be coming in tomorrow

I just received my warranty replacement, and it is an 11a factory refurb device that looks like new. No noticeable screen lag thus far, but it is running awfully warm as it restores all my apps and some data from the Verizon Cloud.

Is there any downside to refurbished devices?

I think not, and I actually prefer buying factory refurbs in most cases when possible because you are assured of the product being carefully inspected. In this case, my phone looks brand new and is performing just fine. The initial heat concern has gone away as the phone has settled in.

Please Help!!!!!
I'm trying to help my sister out who is in Ecuador right now. Her phone was a little slow today and kept going to the red verizon sign - so she turned it off and took the battery out.... when she turned it on it said the SD card is blank. She has 800 pics on it from her trip and is wondering if there is anything to get them back???? Please help!!!! Any suggestions would be helpful!

weird i had the same thing happen a few days ago also...using new phone now.

This issue happened to me out of no where last week and had a replaement sent. Wasn't rooted

same problem here ...
rooted device. nothing special today .. and then: bootloops.
When i remove the battery for a longer time, sometimes the g4 boots properly. But after a few minutes it'll bootloop again.
Any ideas?

What's the manufacturing date of the phone that failed? I'm trying to figure out if it's just a matter of time (the May ones failed first, then June), or if it's only May boards with the issue.

Phone always crashing, even on stock firmware?

Hello all,
This is just the continuation of my last post - http://forum.xda-developers.com/galaxy-s4-tmobile/help/s4-acting-buggy-using-roms-t3306395
I was recommended to use Odin to flash the original 4.4.4 firmware, so I did just that and my phone worked for a few hours. But then, it would freeze again and force reboot. Then it would get stuck in bootloop and I would have to take the battery out to reset it. When this finally loaded, I wouldn't get any service and told me to insert an SIM card even though there was one already inserted. A few moments later it would crash again.
After this, I flashed the 4.4.2 firmware through Odin, and the same things kept happening. I'd only be able to use my phone normally for about an hour or so and then the cycle of crashing and bootlooping would start again.
I noticed that whenever I did a factory reset and wiped all data, the phone would work normally for a short period of time. But as usual, a bit later it will freeze.
Is this just a hardware problem with my phone and practically unsolvable, or is there a fix to this?
Any help will be appreciated, thank you.

Did you restore any data or apps after flashing the fresh firmware?

Nope, I just went to the store to get a couple of my most used apps like WhatsApp, Twitter, and Soundcloud. I didn't restore anything else

Did you take out the micro SD card as well? Do you get messages when the device crashes?

Yup, I tried rebooting without my SD card as well, same problem occurs. And usually what happens is it'll boot up, but becomes unresponsive as soon as I touch it. It will then reboot by itself and go into a bootloop. In the rare occasion I am able to bypass my lock screen after booting, I get a com.process is not responding and my background is all black. This too will eventually freeze and enter a bootloop.
