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.

Hey guys
I tried the one-click root toolkit for mac from android rootz.
Something apparently has gone wrong during the root and I got some error messages and it didn't proceed. Next thing I know the nexus is stuck on google X logo and that's it. It won't load. I tried to recover through the recovery mode a couple of times but now I get the red warning sign when I go into recovery mode. This is only the second day I've had the nexus for. I feel like crying. Please Help
When the red sign appears press the volup down buttons and power button randomly until you get into recovery then factory reset
My 7 and 10 both did that. Just hold power until it turns off, then boot a recovery, wipe everything except system and reboot. It'll come up ok.

I'm having the same issue. However, the recovery I have installed is the non-functional CWM. So I can't factory reset. (I managed to once before CWM bombed, but it didn't change anything.)
I've tried several options via the toolkit. After fighting with the app all day it's finally wound up just saying it can't find adb? (I have a growing dislike for this app and have since uninstalled it.) Adb is right where it belongs and seems to run fine from cmd.
I also can't seem to flash anything via fastboot for some reason. The device throws "failinvaild id command" and fastboot immediately crashes on my laptop.
I managed to get it unlocked. However, I'm unable to flash anything to straighten it out...
Any help would be great.

Thanks for the info. My situation wasn't quite the same as my CWM was the real issue, which wouldn't run long enough to allow for the factory reset boot-loop solution. Kept at it and managed to get CWM to finish the individual formats/resets one at a time.
With a now bootable device, I'm off to replace the recovery... Thanks again.

Basically, a bad USB cable was making fastboot operations flakey, and by the time I discovered it, the recovery program was wrecked. Everything else seems to work fine. The Nexus is running 4.2.2, and I have toolkit 4.3.5, running on win7x64.
I've tried reflashing various recovery programs, including the stock one. No error flashing is reported (with the now-good cable), but going into recovery mode fails, showing the android image with a red triangle and exclamation point in it.
[Edit: To be clear, I have NO recovery menu at all - when I select recovery in the bootloader, I get the regular boot "X" in the middle of the screen, then it is replaced with the android lying on its back with the alert notice above it]
The bootloader appears successfully unlocked, and in fact the entire unlock/root process was fine, once the cable was replaced. That is, no errors were reported, everything seems to be ok, but I can't use the recovery option. Note that the unlock wiped all data, so it was as clean as possible.
Should I completely reflash 4.2.2? Will that even matter?
Is there anything else I can try? I'm not keen to try sideloading 4.2.2, but will, if there are instructions some place.
If this is no go, I'm going to have to try restoring everything to the basic original state and asking for a replacement from Amazon. I don't know how that will go, and this was to be a gift due in about a week, that I was setting up for the recipient. I've spent literally 8 hours on this today, before realizing the flakeyness was due to the USB cable being bad. Any help is very appreciated.

So you've tried using fastboot to flash a custom recovery image? The command fastboot is a part of the Android SDK.
fastboot flash recovery <name of recovery .img>
There's plenty of stickies and information in this forum, which I won't re-hash here.
The stock recovery WILL show the android with the red triangle. To get into recovery from there, I believe you need to hold the up volume key. Other recoveries shouldn't do this though. Perhaps you should try using ROM Manager or Goomanager to flash a recovery from within android.
It took several attempts - flashing stock, then cwm, from the toolkit, before cwm finally "took". It's all working now.
Nexus 7 (2012)
4.4.4 Stock
KTU84P
HW Version - ER3
Bootloader Version - 4.23
Locked Bootloader
Not Rooted
I have a Nexus 7 sitting in front of me that was dropped off by my aunt in hopes that I could repair it for her. It doesn't look too promising, but I thought I'd consult the mighty fine people here on XDA before I give her the bad news. Here's what she says happened. Yesterday, while preforming day to day activities on it (browsing internet, Skyping, Facebook, etc), the device completely froze. After holding down the Power Button and forcing it to shutdown, she booted it back up. Everything seemed to functioned properly for about 30s - 1min when, at that time, the device turned off and rebooted on its own. After booting back up, it started to repeat this cycle. Basically getting stuck in a bootloop. I personally have never witnessed a bootloop like this before, where the device successfully boots up completely into the OS before turning off and repeating. I'm more used to dealing with ones where it might go as far as the manufacturer logo and then repeats. So anway, as I stated, I only have a 30s - 1min window where I can make changes in order to troubleshoot. The first thing I figured I should do was to go into "About Device", turn Developer Mode on and get USB Debugging enabled. I was able to do this and used "adb devices" to confirm its connection to my computer before it looped again. After its next bootloop I headed back into settings because I wanted to take note of the Android version she was running. As I was navigating there, I noticed that the Developer Options were no longer active. Basically as if I hadn't enabled them yet. This made me start thinking that changes being made on the device weren't sticking. I decided to make a few visual changes to the home screen and see if they were still there after the next bootloop. I uninstalled an app, rearranged icon placement, and changed the wallpaper. Once it shutdown and booted back up again, everything was back to the way it was before the changes had been made. The app I had uninstalled was still there, the wallpaper reverted back, and the icons were back in their original location. At this point I decided to see if I could reboot into Safe Mode. Unfortunately, this doesn't work. I am able to get the reboot to Safe Mode confirmation box and tap "Ok" but it remains in Normal mode when it boots back up. I eventually tried to boot into recovery and preform a Factory Reset. I was able to get into recovery and reset the Nexus. Or so I thought. Instead of seeing a Device Setup screen after it wiped, like I assumed I would, it booted up and still had all the data on it. There were no errors during the wipe and it was confirmed with "Data wipe complete." afterwards.
I am absolutely lost. I've never dealt with such an unusual issue before. Especially with it not even reacting to a complete data wipe. So, just to recap . . . I only have 30s - 1min available to interact with the OS before it reboots itself, any changes made during that time don't stick, Device is successful booting into Stock Recovery, and I can successfully get a Fastboot connection when booting to the Bootloader.
Luckily she has come to terms that this might not get fixed and has decided to go a head an order a newer 2013 model. I'd still like to try any solutions that you all might have. Just in case there is a slight glimmer of hope.
Oh, and one last thing I should mention. I tried to see if I could get the bootloader unlocked but it didn't work. This is the first Nexus I've ever had in my possesion, so I'm not really familiar with the tools available for it. I found WugFresh's Root Toolkit and attempted to Unlock with it. The process seemed to go as it should and I didn't receive any errors on the tablet or in the software. However, in the end, it didn't make any changes to the bootloader.
same problem
I have the same problem as you.
Did you find a solution?
Can anybody help us?
Thanks.
I have a similar problem, but I think mine is related to the bootloader.
I'm stuck on 3.34 and that's where it fails ever time I try Wug's Nexus Tool Kit.
Have you tried Nexus Tool Kit yet?

I have tried factory reset from recovery, no errors while wiping but when device restarts nothing has happened: I only have a 30s-1min of old system with all my data and apps or directly bootloop.
Also I have tried flash factory images with Nexus Tool Kit and directly from bootloader. No errors while flashing, apparently has flashed new image system. When device restarts nothing has happened: bootloop or my old system with data and apps for 30s before restart.
Myself and a few others are having the same problem... please keep us updated if you find anything out.

Hi, my wife got an Asus Zenpad 10 (Z300 series) tablet not too long ago, and recently it seemed to be acting up. It didn't seem to know what its battery level was so it'd suddenly shut down and would rarely stay on for a few hours if that.
I've been reading these forums and Google searching every evening for days now to no avail.
The the other day when i turned it on, it was in a bootloop. I had this happen on my own tablet so I was aware of using ADB and the recovery menu to wipe the davlik cache.
Except, that this Asus tablet only has fastboot screen (which I'd not seen before - my Samsung went to a different recovery mode), so I've been researching that more recently.
I got ADB and Fastboot working, erased the cache via Fastboot which stopped the bootloop, but it would only go as far as the logo with the little spinner circle. After messing around with fastboot trying to do a factory reset and put a custom recovery on it (TWRP) it now will only boot to the Asus logo and not even have a spinner anymore!
The flashing of anything - recovery, stock rom from ASUS (this file as I found elsewhere on these forums: UL-P01M-WW-3.3.8.0-user.zip -- although I'm not entirely sure i'm flashing correctly).
Anyway, I'm stuck with only an Asus logo or fastboot mode screen and am not that good with fastboot/adb since I only had to delve into it once to fix my own tablet over a year ago.
If anyone can help that'd be very much appreciated! :good:
[update]
OK so after failing to flash any zips (or anything!) to the device, I left it on in fastboot mode while I went to work. Now upon coming home the tablet is just a black screen! The laptop recognises it because Windows makes that chime sound when its plugged in via USB. But other than that, I can't get a response out of it Button combinations don't seem to help so now I'm not sure what to do!
Can anyone help me please? :crying:
Unless the bootloader is locked, you may have made a mistake trying to flash the ROM and trying to install a custom recovery. Anyways, if you hadn't made any changes yet to the system, I would have said check the battery first because it may be malfunctioning and not the phone it's self. I know from experience that it may have been the battery considering the way you said it was not reading the battery percentage right and shutting down. And that "bootloop", this was probably happening because it didn't have any power to start up the device as this is exactly what my device did when I had a faulty battery. My best bet is to 1 try to get a new battery, and then 2 see if your system is still intact otherwise try and reflash with the stock ROM (through adb or any computer to android debugger) and then reinstalling the right recovery that goes with the device or that of which is c-o-m-p-a-t-a-b-l-e.
Using CM12.1 on my SGH-T999
I exactly got the same issue, nothing I particularly have done as far I know, my tablet suddenly rebooted and now is stuck on Asus logo with the little circle that keeps turning.
I tried to let it go till my tablet get completely discharged and also tried to charge it completely, nothing change.
And when I wanna access to the recovery, I just get the green android mascot with the message "ERROR!". So I can't even access the recovery to reset my tablet :crying:
Edit: Tried a fastboot erase userdata and an erase cache, still bootlooping
Sorted
The only way I fixed this was by returning it to the shop and having the device replaced! Not the ideal solution, but it worked. :good:

Asus has the firmware (Nougat) for this Z300M but I've no idea how you would get this loaded. Something to learn but as long as the OS is available you should be able to get back stock, latest OS............

So I think my Nexus 6P is hard bricked, but I just want to be sure before I issue an RMA.
I was on a plane flying over the Pyrenees and opened the camera to take a picture. The phone froze and started rebooting, which I found strange really strange as it never happened before. Since then, it wasn't able to boot again. The phone is completely stock, running 7.0, apart from the unlocked bootloader that I had unlocked the day I bought it (March/April this year). The phone shows the unlocked bootloader warning, goes to the white Google logo with the padlock below, and then goes back to the unlocked bootloader.
From here I can Power + Vol down and get to bootloader, which I thought would leave me to recover the phone somehow. I know my way around nexus devices so the first thing I tried was scrolling in the bootloader menu and boot into stock recovery. No luck, unlocked bootloader warning, white Google logo and loop. Tried "Factory" in the menu and the same thing happens.
So then I've gained access to a computer and tried downloading a twrp recovery and boot into it. Ran fastboot boot twrp.img, the phone tries to boot again, and the same thing happens. Boot loop. After that, I've downloaded the latest stock Google images and I've run a different set of things, all with no luck. Booting directly from fastboot into stock recovery doesn't work. Flashing stock recovery and trying to enter stock recovery via bootloader menu doesn't work. I've erased and flashed bootloader, radio, and all other partitions (system, boot, recovery, vendor and cache), without any luck. The fastboot commands return "OKAY" but it seems like it's doing nothing.
I am out of ideas, I always thought I would be able to recover a Nexus phone as long as I could reach bootloader mode, but I guess I'm wrong. Should I RMA, or is there anything else I should try?
Thank you.
You say you "Ran fastboot boot twrp.img." Try to do fastboot flash recovery twrp.img from fastboot and see if you can get twrp working. Then try to flash a ROM

Done both, actually. Tried to boot directly from a fastboot command and then tried flashing the actual recovery image to the phone. No luck in both. Never able to get into twrp.
I had the same thing happening to me. I was also using stock 7.0 with an unlocked bootloader. My screen froze during webbrowsing and had to restart the phone. Once booting up, it never came past the Google logo. Getting into recovery didn't work either, just started looping again. Tried to flash twrp, got in there after many tries. Tried flashing all kind of android versions but nothing helped. After that I decided to just use my warrenty and send the phone to the store. They replaced the motherboard and are now sending it back.

Yep, I gave up already. Tried all different sort of thing, and was never able to get into any kind of recovery, let alone Android itself.
Called Google support yesterday evening, a replacement is on its way already.

Needed the RMA anyways. If you had an unlocked bootloader and formatted each partition and then flashed each partition with the corresponding image file from the latest factory image, it was shot. It happens from time to time. Happened to mine as well. 2 or 3 days after I finally got it (pre ordered on launch) I rebooted the phone at some point 2 or 3 days later and it just never turned back on. 100% bone stock. Not even an unlocked bootloader. Nothing would happen when I plugged it into a PC, left it on AC power for hours and hours and still nothing. Holding power 10-15 seconds, nada. RMA'd and luckily this one's been perfect ever since. Good luck with the new device!
