[Q] Not Your Average Bootloop -- Possible Brick

I searched and searched not only here, but other forums as well and did not find a solution to my problem. I've been a long time lurker and know how things go around here, so I made sure I covered my bases. I've been rooting and flashing phones since 2009 and this is the first time I've had a problem I couldn't fix myself.
The phone:
Verizon Galaxy Nexus -- LiquidSmooth 4.1.2 rom -- Latest Franco Kernel
Here's what happened:
I was getting into my car and my phone didn't pair with my stereo like it usually does. I tried turning BT on and off, but not dice. So I hold the power button and select reboot. It pops up with the Google logo as per usual, then the boot animation for about 10 seconds until the animation freezes, the screen goes blank, then the phone vibrates and displays the Google logo again and the cycle continues until I pull the battery.
What I've tried so far:
I tried restoring a nandroid first, no luck. Then I did a factory reset and wiped the cache, no luck. I tried re-flashing other ROMs I had on the device, no luck. I tried doing a factory reset via the WugFresh ToolKit, but the USB drivers don't see it while it's in recovery. Every time the same, although the boot animation changes depending on the ROM.
Anyone have any ideas? Or is this an excuse for me to order a Nexus 4 once they become available again?
Thank you

Have you tried fastboot? You could try re locking the bootloader to format the device.

Try reloading the factory image. Could repair everything, then you can flash your ROM again. I have one up if you need it in the marketplace. Unless you plan on switching to a gsm carrier, you won't be using the nexus 4 on vzw. Why I recently jumped ship.

How do I format the device if not from a PC? I can't get my computer to recognize it. I did format from recovery for /system, /cache, and /data. Again, no luck.

Luckily I had a factory image on there before this happened, but it didn't work. Same issue.

I had the same issue a while back.
Hold down both volume keys along with the power button (loads up into fastboot.) From there you should be able to use adb to lock/unlock the bootloader.

Did it. No change.
Thanks for the replies.

Well if you've relocked/unlocked the bootloader and it still won't boot up then you could always lock it again and bring it to vzw and have them get you a new one.
Or wait for someone smarter to post

Try this...
Try using the Rootkit from MSKIP- http://forum.xda-developers.com/showthread.php?t=1400871
While you have your phone in FASTBOOT, try to push a file to your phone. Try and push the SUPERWIPE.zip for the Galaxy Nexus.
After you push the file to the phone, try to push the factory rom to your phone.
If that does not work the, simply install CWM from the toolkit. This will allow you to boot up to CWM recovery by holding the Volume up & down at the same time, then push the power. This will allow you to do the superwipe.zip and then try to reinstall the rom you want.

[Q] Unresponsive Screen + Bootloop

I brought my phone in to have the charger port replaced. It worked fine ad then all of a sudden the phone boots up, stays booted for a minute and then reboots. also the screen is unresponsive.
I have used a gnex kit to get into CWM and erase cache and dalvik cache and fix permission and the problem is not resolved.
with out the gnex kit i can't even get into CWM and all i get is a little droid guy with an open stomach hatch with a red mark.
i would erase all data and factory reset as a last option but i have some work photos on the device that are extremely important for me to extract. I should also mention that with the CWM kit I am unable to find the files I wish to pull yet for the few seconds I am able to boot into android my photos are there in the album.
can someone please help me find a way to extract those files so I can try to wipe the device and move on?

With factory reset your sdcard will not be touched. You will have all your files (unless youre in stock recovery I think). You can use adb pull /sdcard/ to get all youre files.

so what you're saying is if I boot into CWM with the kit, do a factory reset, all my photos will be there? can you please elaborate?

Yes that is correct. You can wipe everything as long as you dont wipe /sdcard. I am not a 100% sure since you are on stock but I know sure for 99%. Google is your friend

Alright,
alright, we have 50% success!
I was able to get all the files off that I was looking to get, albeit during 20 second intervals in which the phone would allow me to before rebooting....
which brings me to my next point - Phone is stuck in bootloop after following (successfully) this guide to flash stock and unroot which, needless to say, seems strange to me.
Now I supposedly have a fully formatted i9250 maguro with a fresh flash of stock running and i'm stuck in a boot loop which if i leave sitting long enough will eventually get to the "Welcome" [choose your language] screen with an unresponsive display panel until it reboots after about 30 seconds.
please help.
EDIT: I flashed the Factory Image Android 4.2.2 (JDQ39) and still stuck in bootloop with unresponsive screen. maybe this is better as a paperweight??

Thats strange. But you have your files and you are on completely stock unrooted. If you still have warranty you can send it back. Maybe you can try this: http://xda-university.com/as-a-user/how-to-recover-from-a-bootloop

Strange Fix reveals deeper issue
good news and bad news
Alright, so I have swapped the motherboard with an old gnex i had laying around that has a broken screen that wouldn't turn on at all..
I found out that the motherboard on the old phone must be dead because it won't work in the newer phone so I put the guts of the newer on into the broken screen phone and it worked perfectly - albeit with a huge crack in it. so i then thought maybe the issue was solved and put the guts that worked back into the original phone and it is unresponsive and reboots... I've come to the conclusion that the screen is the issue on that device.
but is this fixable??? i have taken the whole thing apart and can't see how that screen could be shorting the device and cause it to reboot nor can i understand why it wouldn't be responsive to the touch for no reason.
anybody have a clue how i can fix that?

[Q] Hardbricked? do not reboot HELP!!!

hi everybody,
I'm usually more active on auto forums but I need your help.
wanting to install a custom rom, I'm a but lost in the manipulations. Last night when I wanted to turn on the tab (only with the power button), I had the google logo that was displayed at the top right and the small rectangle of recovery menu (start, recovery, reboot bootloader and poweroff). With buttons I could choose one of four functions. I had access to the recovery menu, when I choosen restart bootloader, it well reboot and poweroff worked well too. By when I clicked start I had a small line at the top left telling me "boot failed"
I try to flash everything thanks to a tutorial.
So I'm DL the original elements but still the same issue. Having struggled until 3am I give up. This morning when I tried to turn on the tab, I did even more than what I have explained below whatsoever with the power button or volume down + power nothing happens the screen stays black.
Any Ideas?
PS sorry for the language I'm french

If you bought it from a local store or if a local store carries it, I'd recommend just retuning for a new one. Haven't seen anyone having your problem. If it won't even turn on, then any store should exchange it, or return it, with no questions ask once they see how your tablet is behaving!!

I'm seriously thinking of this solution but I'm afraid before they give me a new one they send it to their after sales service. If they find out I have rooted it and unlock the bootloader they will make nothing for me

Have you tried returning it to stock to see if it'll boot then? It could just be a bad flash.

I tried every thing.I downloaded nakasig-jwr66v-factory-aebc7b11 and I flash everything but nothing happens. Yesterday evening I was able to boot it (even if it was a bad bood I had only access to recovery mode), but from this morning I tried everything but nothing happens. Even if I plug it to my PC impossible to boot it. The PC do not recognize it (I checked in ADB mode and fastboot mode but the PC do not recognize it)

Good English friend. Can you boot into TWRP? If yes, install any custom ROM after a thorough wipe in recovery. Good luck!

Thank you .
No it doesn't works. For the time being my first to issue is to succeed to boot it at least as yesterday evening.

So if I'm understanding you correctly the Nexus 7 won't even turn on at all now, right? Try holding the power button down for at least 30 seconds and see if it will turn on.
Also, the Nakasig image is for the 2012 version of the Nexus 7 and won't work with the new one. The new 2013 version is named Flo but Google hasn't released the factory images for it yet. However, if you can get the device to power on and back into bootloader mode you should be ok as there are a few unofficial versions of the Flo image on the forum.
One last thing, to quickly boot into bootloader mode hold the Volume Down button while pressing the power button. But try just the power button for at least 30 seconds first to see if you can get it to turn on at all.

+1 Try plugging it in for awhile too. You want to get to the bootloader - the screen with the Android where you go through the options with the volume buttons. Once there,you can use fastboot to flash TWRP and fix from there. Again, stay away from the OLD Nexus files.

I tried to keep on the power button during 1 min with and without charger and pluged to PC : nothing happens. I tried the same thing with volume down + power and nothing happens either

I'm not sure what might help next. Perhaps someone with more experience will come along with advice. If it were me I would probably return it and tell them the power button stopped working.

So you flashed everything from the file nakasig-jwr66v-factory-aebc7b11.tgz? It's for the 1st gen Nexus 7 Mobile version. It would also flash the bootloader and radio. I am guessing that flashing the wrong bootloader might have bricked your device. Someone please correct me if i am wrong.

I'm seriously thinking of this solution. I'm just worry if asus find out everything I made

the old nexus 7 or the new 2013 model with a camera on the back? is yours wifi only or 3g capable?
The only thing i can think of is to plug into your pc's usb port and hold the power button for 30sec.
Then unplug from PC and press power button for about 15sec and you should see the google logo - if not, i think your bootloader is bricked from flashing the wrong one.
If you do see the google logo, keep holding power and also press vol down as soon as you see the logo - should get you into the bootloader.
Messing up the bootloader is the only way you can brick a nexus, feel sorry for ya man

noob question: so you are using a Nexus 7 (2013) and you flashed an old-nexus-7 ROM on your device? If you're using the new one, here is the ROM for the new one http://forum.xda-developers.com/showthread.php?p=44054613.
I have just had the same problem. Flash the old nexus 7 kernel on the new one, luckily I fixed it

There is a different forum for the 2012 Nexus 7 here. This forum is for the 2013 version.

[Q] Help! Stock Nexus 7 (2013) bricked?

Ok, so I have a 32gb 2013 Nexus 7 which is now bricked and i didn't do anything to brick it! Really!
It's stock, not even rooted... nothing. Never got around to doing anything to it... just left it alone.
So last night it was having trouble connecting to my home wifi so I rebooted it. When it came back up, it got stuck at the white "Google" logo, and ... nothing... no animation, no nothing.
I left it for the day and came back, and it's still doing that.
So - dug a little and decided I'd do a hard reset.... i can get into recovery (stock), i cleared the cache... but now when I try to wipe data/factory reset... it gets stuck there too.
I've got the Android guy with "Erasing..." below him. A blue progress bar that is NOT MOVING and text ...
-- Wiping data...
Formatting /data...
and that's it just sits there.
have tried it twice already and nothing.
Any suggestions?

You can use it to restore to stock without using recovery mode. As you open it you have to download some packages(just accept).
I will attach an image below to show you what it should look like.
Secondly you need to enter bootloader mode as shown in this video: https://www.youtube.com/watch?v=VV1ffMCXRg4 (Skip to 2:30)
Basically you make sure the tab is off then press the volume up button then press the power button and hold both.
Back to the Nexus Root Toolkit. Click Flash Stock+ Unroot while having the Status as: Soft Bricked/Bootloop just like in the picture below.
Just accept all the request made by the program and you should be fine.

@kenrothman don't worry, your N7 will be fine. Our device has a bit "nervous" /data partition. The method from the post above should work.
Alternatively, you could also do some other methods with price of data lost but try this first.

can't seem to do this because my bootloader is locked.
100% stock, this one is.
i tried to unlock the bootloader, because at this point it's ok if i have to wipe everything...
but it just hangs on the "yes" "no" page after i select "yes" and hit the power button.
ugh.

Did you ever use ADB / fastboot? I prefer to do such things manually as the tools might do something else than I want.
If you didn't use it yet, there is an excellent guide by comminus for N7 2012 how to flash factory image with fastboot.
Find it and in the beginning is the part with installing drivers, SDK etc. That part is identic for the N7, also bootloader unlocking.

Any updates yet? In the bootloader (if you can get to it) does the line "LOCK STATE" say locked or unlocked?

Why not use it to fix your device.
Heres the link: http://www.wugfresh.com/

sorry, didn't have much time over the weekend.
i had previously tried to use 'fasboot oem unlock' on my mac, but that hangs as well.
i'm beginning to think this may be a hardware issue... i did a support chat session with google who basically told me i had done everything they could think of and they sent me to Asus. I haven't tried with them yet.
I'm willing to completely wipe the thing to bone stock at this point... i mean, i hadn't even rooted it... never felt the need to.
The "factory reset" from recovery really should just stomp on it, but that hangs too.
I will probably give Asus support a shot... esp if it's hardware and needs to be replaced or whatever.

Touch responsive issue

My partner just bought a brand new 5X, 16gb white. Serial no. 602.
She was booted up the phone today, fine, started syncing stuff what have you. Started updating to the Jan update etc until the latest March update installed. Now, the touch screen doesn't respond. You have to turn the screen off and on a few times for you to be able to use the screen for a few seconds before it does it again.
I have;
1. Gone into settings to ensure magnification gesture or something is turned off, and it was.
2. Wiped cache in bootloader, factory reset
What's causing the issue? Is it hardware? It was fine before the March update.
