[Q] Unbelievable Galaxy Nexus problem.

This is my first post on the XDA forum. I registered only 2 try 2 have a reply 2 a problem that in my language (italian) is impossible to find out.
This is the best place for everything concerning android world so I hope to be lucky.
This morning my galaxy nexus, while I was playing @ paradise island, freezed and started to play several times a sound that was like an emergency (almost like the overheat processor beep in the computer cases - never heard that before). After this emergency beep the phone shutted off.
When I turned it on the Google logo appears but it start having gliches and reboot. This infinite times until the battery is removed. Sometimes it arrives to the colorful background but that times also it freeze (without gliches) and reboot.
Tryin 2 find out the problem I had a soft reset (battery off for 10 mins) but nothing.
I tried also an hard reset. The phone anyway after having selected RECOVERY MODE from the apposite menu start the google logo and when reaches the "red alert signal droid" the droid is gliched and the phone freeze and reboot. And start another time infinite reboots.
Someone know what kind of problem the phone have? It enters without problems in odin mode and the (I kind is called) bootload mode but don't start the recovery mode. I'm totally n00b, the phone is in fact stock, and I don't want 2 wait 1 month of assistance time if is a problem that can be resolved also @ home.
Please help me if you can and thanks for gifting me with your time.

Sorry to ask but I don't understand gliched, can you get in Stock Recovery (the "red alert signal droid" as you call it), push volume up and power at the same time and enter the recovery menu? Or not?

no I can't. The droid is gliched so the volume up + power combo doesn't work. The phone reboot some times. Some others times (like the trying I had now) the phone freezes.

Try flash the google stock images through fastboot, there are threads with instructions and links to everything you will need.
You should be able to fix whatever is wrong.

If doing it I can loose warranty?

No, you can re-lock your bootloader when you are done.

And the problem for sure is going 2 be solved? Seems super!

It MAY solve your problems, if they are software related.
If its a hardware problem it won't.
Give it a try anyway.

He is better off using fastboot and learning something.
Tool kits are the wrong way to do things, it is better to know what is actually happening when you pick an option in a toolkit.

the problem is that I don't know anything of this stuff. I don't know how to start.
The toolkit guide is huge and I think i should do only 2 or 3 of the all listed operation...
For now i took only the kit, the pdanet for win 64 and the yakju 4.0.4 from the google page. I don't know how 2 put them on and in which order.

.....

Oh, phone of my colleague has the same issue. We don't know what to do cause we can't connect Nexus to computer. When trying to do this Fastboot 2147483647 error occurs. Adb devices gives empty list.

Sounds like a hardware problem to me

Not sure if this is different on other phones but for me to get to recovery its not Volume up + Power. Its Volume up + volume down + power (i.e. hold both volume buttons then hold power button until it vibrates or the google logo shows up)

[Q] Non-working, rooted and still under warrenty. Nothing I can do?

I've got a dilemma. My rooted Verizon GNex just stopped working today. Yesterday, it was working fine. I plugged it up at night before bed and about an hour ago, I grab it off the charge. Nothing happened when I hit the power button which was strange because I never turn it off and I didn't let the battery die. I pressed and held and "Google" and the little lock on the bottom came up so I set the phone down while it powered on. 5 minutes later, it's still in that state, then a few seconds later, the screen goes black and nothing happened. I took the battery out and put it back in twice and nothing happens. I can't remember downloading any apps other than Zagat and a guide for Ingress in the last few days. A PDF online or two. What do I do with a rooted phone that's still under warranty (just barely so time is a factor)? Can they really check if the phone won't even turn on?

My old roommate sent her unlocked/rooted Gnex back to VZW when her charging port stopped working. They never charged her for it or anything, but it did say something like "you would be responsible to pay $X if rooted blah blah.." Either they are bluffing or she slipped in.
Did you try clearing data, factory reset?

How can I do a factor reset if it won't turn on? All I know is pulling the battery or holding the power and volume buttons at once.

I don't think a factory reset wipes root.
If you hold volume (-) and power from a powered off state can you boot to fastboot mode and is it still recognized by your PC?

Unless it's different on the VZW than a GSM phone you need to hold volume up & volume down + power to get to the bootloader (fastboot mode)

With the phone off hold both volume buttons and the power button, then use the down volume key to navigate to recovery, and power to select the option. Once in recovery you will see wipe data/ factory reset option.
Also if you have a backup you can restore it from recovery.

No a factory reset wont wipe root, but if it solves his problem and the phone is functional again he wont need to exchange it through warranty, so no need to unroot.

Holy crud that worked! It's on and it shows the green start arrow pointing toward the power button which does nothing when I press it (I hear some Samsungs have issues with the power button not working). Under the Android bot it says, "Downloading... Do not turn off target!" but my PC (W7) couldn't download whatever driver it needed. And I just realized I do have the Wugs toolkit. Can I unroot if I'm unable to get critical buttons on my phone top act properly?

Try the factory reset first. If that works you get to keep the phone like WiredPirate said. Check out this guide to install drivers and flash stock Google images if you have to.
http://forum.xda-developers.com/showthread.php?p=25477039
Edit: sorry I have been up for a while. Power off the phone. Pull battery if you need to. Power + BOTH volume buttons at the same time. Use the volume keys to navigate to recovery mode and power to select it. If the phone will boot to recovery try a factory reset and reboot. If that works, awesome. If not follow the guide above to flash the phone to stock.

Instead of plugging it up to your computer before/after it boots, can you press the volume down key twice for it to display "recovery" on that green arrow?.. Then hit the power button to boot into recovery. No USB, no toolkit or computer. Then do a factory reset and/or restore a backup and see if the phone boots normal.

It wasn't working working without being plugged up to the computer and now the phone is on the lock screen. What I'm going to do is unroot, backup, and decide whether or not to take it to Verizon. I want to but if I can't actually show them anything, I wonder what they'll do. Looks like everything seemss normal for now. Thanks for the help!

Oh okay, well good deal.. Glad everything is back to a more stable state now. :good:

Hey!
I have got the same Problem (though GSM version)! I cant boot up my system. When I turn the device on the Google screen appears along with the unlocked lock.

Delete the drivers you see for the phone inside of device manager. Now go back to that topic, scroll all the way up to the very beginning and follow the steps. It tells you exactly how to correctly install the drivers to get your phone recognized.

[Q] Hard brick

Woke up this morning and my N7 wouldn't turn on. Plugged it in and the charging indicator came up showing at nearly full charge. Holding the power button then turned it on. Went away for an hour or two, came back and it was off. When I turned it back on it was stuck on the X screen. Forcing a reboot with power+vol just led to the tablet turning off. And now I just plugged it into my computer and QHSUSB_DLOAD came up.
Just got the damn thing a couple days ago and it was 100% stock. Any ideas as to what may have caused this?

Just unplugged it and it turned on but is again stuck on the X. Is QHSUSB_DLOAD no longer indicative of a hard brick?

I'm a newbie here, but let's try.
If you can get to the X one, then I think it's not brick yet.
Maybe your should try to press pwer button and volume down to get to fastboot. You press this combination when your Nexus is turned off.

once I turn it off the whole cycle starts over again. It's sporadically deciding whether or not it wants to boot but I'll keep trying to get into fastboot

In doing a little googling it looks to be possibly caused by the update. If you look up the error, you will see a common problem where HTC bricked a bunch of different phones when they pushed an ota a while back. I would say just return it and get a new one . You could do some research and try it yourself. Are you able to get into your bootloader ( vol+ and Vol - when you trun it on)?

I was able to get into it this morning and I wiped my cache. The next time it decides to turn on/I can get it into the bootloader I'll try a factory reset

Well something got corrupted, but if its booting its not hard bricked (that's good news). Luckily for you as well the aosp images are up so if you want to do a restore you can snag your images, and just do a fastboot install. I hope this isn't indicative of another problem with the device itself, I still maintain that you should probably exchange your device for a new one if you did indeed do nothing to the device. It would be a shame if the same problem happened again because of a faulty component.

Yeah, I most likely will. It'll boot to the X probably once every 25 tries so there's something weird going on and it's probably safer just to return it then find a fix and have it happen again.

Just out of curiosity, where did you purchase it from? Does the seller recognize a lemon as returnable, would you possibly have to tell them you just didn't like it?

Mine is just stuck on Google...... I got into fastboot and flashes stock image but it still will not get past google. I can not boot it to recovery or anything other than fastboot.

What happens when you do vol down and power to try and get into the bootloader? Nothing at all?

Stuck at Google means /system is corrupted or erased (fastboot to restore system.img)
Stuck at X means something wrong with userdata/cache (factory restore from recovery)
Won't start at all with USB identifying as QHSUSB_DLOAD means either bootloader corrupted or raw partitions corrupted
I suggest you reflash again.

Please help - I fear my Nexus is bricked

Hi,
I'm sorry to trouble you all, but I fear that my lovely new tablet is bricked
I unlocked/rooted 6 days ago using Wug's tool and everything has been fine. Turned the tablet on today and all i get is the white google logo and the unlocked symbol at the bottom.
I can't get to bootloader or recovery by the power/volume buttons. If i hold down power and vol down for long enough I get a picture of a dead android with a red warning triangle over his chest
There is a windows sound when the device is plugged in via USB, but nothing appears in device manager.
As such, I am at a bit of a loss as to what to do, can anyone help please?

Close to impossible to brick a nexus device.
Recommend downloading the factory image, unzip and run the flash all batch file.

Shut down nexus 7. Now hold volume down and power. When you see the next screen you will press up until the you see recovery mode. Now press power and you will see the Android guy and the red exclamation point. Hold the power and the volume up. You should now be in recovery mode. Use fastboot commands to restore.

My nexus 7 had this issue and my friend told me your eMMC chip is wasted. I gave my little nephew my tablet to play with and i started using it like a mousepad. Just one day i tried pressing these keys at random and my device booted up.
I flashed it so many times unknowgingly this was issue.
Can i ask, why this even happens ?

I have it as well, after I shut it down I have to wait several minutes, then I can plug it to the AC and it will respond. Happened after unlocking. Will try to lock it back and let's hope it fix.
EDIT: additional info: if I try access fastboot, it won't work. Let's hope I can fix it.
EDIT2: additional info/2: after flashing stock, I could turn the tablet on normally. It fails when trying to enter fastboot with hardware keys.
EDIT3: I noticed that this actually happens only when I try to enter bootloader with power+vol up + vol down. with only power + vol down I have no problems.
EDIT4: solved by multiple stock ROM flashing and lockink the bootloader. Now I redid the unlock and flashed a cROM, we will see...

After the 4.3 upgrade. I reseted N7, but with unlocked bootloader and rooted. I'll try reset again, lock the bootloader and unroot to see.
For me just the power button when N7 is unplugged doesnt work.
