Is there any way a Nexus 7 can be bricked to the point where it needs to be sent in for repair by flashing things other than by erasing the bootloader and rebooting?
I just want to make sure there aren't any gotchas before getting started.
Looks like I did. I accidentally flashed the nakasig factory rom(my n7 is wifi not gsm) and my userdata partition is broken. I can't format it or erase it. Rom's doesn't boot. Screen is jamming after using recovery for 5 minutes and boot animation shows up for 30-40 seconds and then jamming. Also bootloader jamms too when I stay too much. Its needed to hold about 30 seconds to turn it on. And I still couldn't find a solution to this. And yes I tried to flash nakasi factory image but it doesn't work.

Hey,
I need some help with my Nexus 10, it's stuck at the moment.
I ran fastboot oem unlock via the Samsung Google Nexus 10 ToolKit 1.3.0 (updated for 4.2.2) and as soon as it was done it rebooted and was stuck...
Booting normally it gets to the bootlogo and just sits there forever, going round and round and round.
If I try to boot into fastboot it shows that it's unlocked but I can't change change to recovery using the volume rocker it's just a solid static screen, only choice is to start which boots back into the normal boot logo.
I have no way to use adb or fastboot... it's just stuck :/ How do I recover/unbrick this?
Any help would be much appreciated.

Reboot holding Power and both volume buttons and you should be able to get to recovery

I'm on the xda-devs irc at the moment and we've got so far... but still its messed up.
- Recovery is dead (can't get into it atm, orange triangle guy every time)
- Flashed stock via fastboot and unrooted, but on reboot I get the triangle guy.
- I can boot into unsecure roms (temporary)
- I can boot into temporary recoverys, clearing cache works but davlik cache and factory reset doesn't work both say "failed"
I'm currently awaiting the guy whos been helping me get back from the shops.
From what I remember you need to either install something or run a command after "oem unlock" for security reasons. Android wont let you boot back into the OS until you have wiped all the data after the unlock.
The orange guy means it's working. There's a button combo to hit at that screen to get the recovery to boot. Once there do a factory reset and your done.
That's why toolkits sick, they teach you nothing and when they break your stuck

Can you flash a factory image to it via fastboot?

The pressing 3 buttons at once; cycling to recovery... method wasnt working because there was no recovery accessable what so ever and temporary recoveries weren't working.
That's what a few guys in IRC said too about the toolkits haha
Thankfully some guy by the name of YellowGTO spent some time helping me out and we finally got there in the end, he's awesome and extremely patient

Okay, updates for everyone just incase someone else gets the problem.
- Factory Images via fastboot flashed fine but never stuck, just kept returning me to triangle dude.
- Fix permissions, did nothing
- Restoring stock recovery did nothing, I still couldn't get to a recovery.
- Temporary recoveries only had limited functionality.
I decided to unlock an already unlocked phone again
I flashed stock, Ran file permissions
Used the temporary recovery to clear the cache/davlik (previously didn't work)
I re-rooted, Installed TWRP 2.4.4.0, this finally stuck.
I double checked that it had stuck by booting the system, rebooting into recovery, powering device of and powering it on to Android. It was all working perfectly.
I then made my backup and put a custom rom and kernel on, it's working lovely now.
It seems that somewhere during the oem unlock it messed up some partitions or something resulting in recoveries and flashing not to work/stick.
Good to hear it's working for you. The issue is that the stock N10 bootloader does not wipe the data partitions correctly as it should. So after an unlock you need to go into the stock recovery and wipe it. Boot once, then go and flash all your flasheys

That's the thing, the recovery wasn't available in any way shape or form and temporary recoveries wouldn't wipe the cache... the oem unlock went wrong somehow even though it had full power, wasn't interrupted or anything.
I'm glad it's all working now, I thought the device was completely dead at one stage.
I think you had the problem almost everyone runs into:
As you can see in the video, you just have to try for a bit to actually get the recovery menu to open - My heart dropped a little before I knew that as well

I think you are right and that was his problem..... The toolkit actually told him how to handle this ... but who reads all the that text anyway
A friend has given me his N4 in an attempt to fix it, seemingly the problem was caused with him doing a factory reset. It's possible the battery went flat during.
The phone gets stuck at the boot logo and will not factory reset from recovery mode. I can unlock the phone but any attempt to flash the stock image will result in the phone re-locking itself a few seconds later and the flash then begins to fail. Very odd.
Any ideas where to go next?
Thanks
Sounds like it could be faulty motherboard, bootloader not unlocking properly is a common symptom.
Sounds like bad emmc, hardware issues. You will have to replace the device.

Before replacing anything I would suggest to update your recovery and try flashing again
And don't forget to wipe the system partition.
Hoping someone can help that has run into this issue before...
Was browsing the web on Chrome today when my Nexus 10 locked up as it sometimes does. I rebooted it and it stuck at the four bouncing circles for a good 30 minutes. Did a hard reset and then nothing. Holding the power button down for any amount of time didn't help at all. I can get into Fastboot and have tried loading stock firmware, custom ROMs, TWRP and nothing seems to help.
The power button now does absolutely nothing. Screen just stays black and doesn't vibrate. I can still get into Fastboot. I know it's hard to brick one of these but this has to be a software issue as the screen still works in Fastboot and all the keys still work to get me there.
Any ideas?
Did you try a full wipe from fastboot?
fastboot erase system -w
fastboot erase boot
fastboot erase recovery
Then use fastboot to flash the factory firmware/software?
Tip: if you use the flash-all.bat everything will be erased and installed automatically

Wife's phone got stuck in a bootloop last night, just stayed on the moto logo. Tried wiping cache and then data from recovery. phone now boots to moto then a black screen. I can see the device in fastboot, but not in recovery. I want to unlock the phone so that I can reflash the OS either from a custom recovery or from fastboot, but since I cant fully boot, I cant get to the developer options. This phone has never been unlocked/rooted or anything.
Is there a way to unlock the bootloader without going into the developer options and enabling it?

No there is no way to unlock bootloader without allowing OEM unlock, you're gonna wanna flash the latest version of stock available for your phone. Unfortunately I'm not very familiar with the commands so maybe another user can chime in here!

You cannot unlock BL without "allow oem unlock" enabled.
Usb debugging you can't enable with fastboot.
You can try to erase with commands:
fastboot erase userdata
fastboot erase cache
fastboot erase customize
fastboot reboot
Give it some time.
How long are you waiting for it to boot after a factory reset? This can take 30 minutes... sometimes more.

I've waited at least 20 mins (not really timing it.) but with the black screen (screen on, not displaying anything) after the boot screen, how can I be sure its actually doing anything?
Honestly... Locked and stock there isn't much you can do. If we had the latest firmware image, maybe, but we are a release behind with no way knowing when, or if, we will ever get the current one.
There are two likely cases here for the cause of this problem... Actually, the cause is corruption of data on the internal emmc chip, the reason behind that corruption is the issue. It is either a faulty emmc chip or a fluke from cosmic radiation, static electricity, or who knows what. Either way, there since a factory reset isn't fixing it and we don't have a current firmware image your only option is send it in to Moto or replace it.
I replaced my GNEX10 battery last january. Aside from the battery calibration being off... (which eventually corrected itself!) it's been working fine. As of late it had rebooted itself while I was using it a few times. A few days ago, it had enough battery such that I left it on overnight. I picked it up the next morning and the notification lamp was flashing so I knew it was still on. I tried to wake it up without success. Usually a quick tap on the power button should do it. Nothing. So I rebooted... and on the google logo it stuck. I knew that a factory reset was probably in order since I didn't do it when I replaced the batter... I got it into the recovery screen... but I could not get the menu. I likely didn't press the right volume rocker. Then I tried again... booted to the bootloader, and selected recovery. This time, and since, only the google logo comes up. No andy on his back with "no command". It just tries to boot into something. I can't do a factory reset this way.
I tried the Nexus Root Toolkit. I can only get it to recognize the device if it's in the bootloader... when I try to use it to boot to recovery, same thing and the NRT says waiting for device... and gets no further. I tried to use it to flash (stock?) recovery but the N10 just sits there on the twrp logo screen and nothing more after temporarily booting into twrp. Just keeps saying "waiting for device"
Anyone have any suggestions! Getting seriously bummed!
So one more data point... I manually rebooted into the bootloader after trying to flash the stock recovery using the NRT. Then it appeared to flash the recovery image.... here is the bit of the log where it ended up:
Checking Fastboot Connectivity
fastboot devices
R32CB04GHGT fastboot
+ Fastboot Device Connected
Flashing Stock Recovery to RECOVERY partition...
fastboot flash recovery "C:\usr\NRT\data\Recovery_Stock\recovery_stock_mantaray_5.1.1_LMY49J.img"
Temporarily Booting TWRP...
fastboot boot "C:\usr\NRT\data\Recovery_Custom\TWRP\twrp-3.0.2-0-manta.img"
Flashing 'undo-perm-recovery-signed.zip'...
Waiting for your device...
That's where it ended up... not getting any further. Once again, attempting to boot into recovery gets it stuck on the Google logo.
How screwed am I? Is there a thread somewhere in the forum anyone can point me at?
Well, in spite of the crickets... I understand. I've managed to resurrect my Nexus 10. Alas there are no good contemporary replacements. The last so-called nexus table google put out there was too damn expensive in the first place and they seem to have abandoned the tablet market to others.
So the key question here: So long as I can get this tablet into the bootloader is it generally possible to reflash a stock image? I'd like to know of any types of caveats etc. The mystery I have still though is: How or why did my N10 get into this state (of of only being able to get to the Google screen) in the first place? I didn't have any questionable apps installed etc. I was totally on stock. One thing that did happen a week or two prior to my tablet going belly up... was somehow the thing lost my google account info and gmail had none of my accounts in place... it was very odd.
I did have to wipe the system because evidently you can't flash anything onto a locked bootloader (the Nexus Root Toolkit by wugfresh is up to date so far as the N10 is concerned at least). I know I could have resorted to using fastboot.exe and the adb directly but this was a touch easier. Alas the backup options for it say you need an unlocked bootloader which seems to be a chicken/egg issue if you've always been on stock.... so it goes.
