N7 stuck at loading screen, fastboot doesn't work, recovery mode doesn't boot.

I was running ParanoidAndroid perfectly until it crashed and not it gets stuck at the loading screen of the ROM (not the Google logo). I'm able to turn it off and get into Bootloader. From there if I choose Recovery mode, it gets stuck at Google logo.
If I plug it into the PC while in booatloader, it gets detected as "Android" but no driver (I'm sure I installed it before with the Toolkit). Toolkit just won't detect the device anymore, keeps getting stuck at the <waiting for device> command.
If I plug it into the PC while stuck at the ParanoidAndroid loading screen, I see MTP and Nexus in Device Manager but w/o drivers.
What can I do now? Any input is appreciated.
Thanks.

Bump.

Have you tried fastboot from the bootloader? Try this(assuming Windows):
-copy your recovery image of choice to your fastboot folder on your PC.
-boot to the bootloader with usb connected.
-open cmd window and navigate to fastboot folder
-type: fastboot boot insertrecoverynamehere.img
It should boot into the recovery from there. Make sure it's the same recovery you used for your latest backup.
Edit: I just read the subject line saying fastboot didn't work. Odd that it would just stop working from the bootloader like that. Have you tried manually updating the driver? Or maybe adb when it recognizes the device as MTP?

Thanks for the suggestion, but I figured out the problem. I'm such a dumbass. I forgot that last time I did this on a friend's computer. Apparently, the toolkit doesn't work properly on Windows 8 64-bit... (at least not on mine). I plugged it into a friend's laptop running W7 and was able to flash recovery again. Smooth sailing from there. Wonder what corrupted recovery.

I've never been able to cold boot my recovery - only through the goomanager app(for TWRP). I believe it's a known bug. I can only boot recovery from the bootloader when my N7 is plugged into my laptop via usb. Power or another laptop don't count. Oddly enough, It also works if I plug it into my Galaxy Nexus via USB+OTG.

Hm, perhaps that was the problem? But I was able to cold boot into recovery after reflashing TWRP... Anyhow, I'm glad I didn't have to restore a recovery image as I haven't made a backup since the last PA update

It worked for me only once after reflashing the recovery. Never again after that. Hopefully it gets fixed soon, but until then, I carry my USB cables with me if I'm flashing new roms

[Q] Help with bricked Nexus 10

I am trying to root my Nexus 10. This is what I did, but it ended up bricked!
I installed the Android SDK on my Windows 7 computer, and downloaded the Android USB drivers and tools.
I turned on USB debugging, and checked I could see the device with adb list devices.
I downloaded recovery-clockwork-touch-6.0.4.3-manta.img, booted the tablet into bootloader, and flashed it
Code:
fastboot oem unlock
fastboot flash recovery recovery-clockwork-touch-6.0.4.3-manta.img
That seemed to work, so I went into recovery, but recovery had all sorts of errors - it couldn't find the sdcard, or mount most of the partitions.
Rebooting stops in the animated logo, apparently for ever.
I have since tried to reload the factory image, but the computer no longer recognises the device - fastboot devices returns nothing.
Help!!!
[Later] The tablet was running the latest O/S (if I could boot it, I could tell you the number!)
Things have got worse. Now, when I go into bootloader mode, the volume keys don't do anything any more, so I can't even turn it off now

Make sure fastboot is set up properly, may need to reinstall drivers or try another computer or try another USB
http://forum.xda-developers.com/showthread.php?t=2277112
I have a feeling the recovery you flashed was corrupt in some way, did you by chance check the md5sum of the image first?
If your able to get fastboot to recognize tab
fastboot erase recovery
fastboot erase system -w
fastboot erase boot
Download latest twrp recovery
Check md5sum
fastboot flash recovery nameofrecovery.img
Then you will either need to flash stock system.img from fastboot or boot to new recovery and adb sideload a ROM
Hopefully your emmc is not to severely corrupt to all this, best of luck!

Thanks, that was pretty much what I did. The trick was to get it working in boot loader mode. I kept trying to reboot it, and in the end holding down power plus both volume up and down all at the same time for 2 beeps made it work.

I have the same problem, however I can't access my Nexus 10, fastboot devices and adb devices gives back an empty line, so I can't access the N10 with fastboot or adb, to lash a ROM. Factory reset from CWM doesn't work, ˛internal card can't be accessed from CWM ("E: Can't mount /sdcard).
How can I get out of this trouble? (Solutions in forums usually involve reflashing with fastboot or formatting the external SD card. These solutions don't work here...
Any idea would be highly appreciated...

Keep trying to reboot into bootloader mode, until it works. Hold down power and both volume buttons at the same time until it beeps twice. If the volume buttons then work to change the option on the left, but fastboot devices on the pc shows nothing, try reinstalling the Google drivers on the pc (via Device Manager, update drivers, have disk). (may have missed out a step in device manager instructions, but there are plenty of Google hits on installing add drivers if you don't already know how).

Sorry, I don't understand what you mean.
I can get into into bootloader mode after keeping the 3 buttons (power+volume up+volume down) pushed together (after two beeps). From there I can't boot the device. (Boot gets into the Google animation forever), so as factory reset.
Also device manager doesn't see the N10, so I can't update the drivers on my PC.

After some repeated turning off and on, now I can see the N10 from the PC (also updated the USB drivers to be on the safe side).
If I enter the bootloader, fastboot sees the N10 in a normal form, if from there I go into recovery mode, adb sees the N10 in recovery mode. Should I proceed from here by using fastboot, or rather adb?
Csaba

You should just use volume up + power (or the whatever the volume rocker button closer to power key) never had it beep to get there
To both of you, follow the steps from above, so long as it isn't a hardware issue this will get you working

Glad you have managed to make the device visible again (it's really scary when you can't, I know from yesterday!).
Go into bootloader mode (not recovery), and follow the fastboot instructions demkantor gave earlier in the thread.
Get your factory image from https://developers.google.com/android/nexus/images#mantaray.
Get TWRP recovery from http://teamw.in/project/twrp2/128.
At least, that's how I did it.

Thank you very much. Tablet is up and running again. :good:
Now, my next question, after being unsuccessful with CWM, I tried using TWRP for rooting the tablet, however it wouldnt start.
When I go from the bootloader into recovery mode only a laying android figure is displayed with a red triangle with an exclamation mark inside.
I have USB debugging enabled. What can be the problem?

[Q] Boot doesn't go beyond rotating circles. Help!!

I tried to search, but in vain.
Hardware: Nexus 4
Software : Android 4.4.4
For reasons that are not clear to me the machine restarted and is stuck in those 4 rotating circles, and doesnt go beyond it. Tried multiple things such rebooting, rebooting into recovery and booting again, tried adb to see if it can see the machine in recovery mode, but to no avail.
Can someone please help? Thanks in advance.

Did you do anything, flash anything to get the boot loop? Boot loop can usually be cleared by doing a factory reset. But you'll have to reset up your phone afterwards

This is a stock android and have no changes whatsoever except automatic update to 4.4.4. Only thing that is different is it is unlocked.
For last one week the phone kept complaining that it was unable to back up photos and videos. So I kept the wifi on over the night, and next morning I saw what i thought was it was trying to reboot but unable to do.
Is it possible to connect to machine while it is in recovery mode? My ADB can't discover the device either in recovery mode or while it is trying to boot. Is there a way to press some button and hard reset it?

I can get into bootloader - if you mean by pressing down volume button and powering on - so you see a few options such as 'Start', 'Restart Bootloader' et al.'
If I can get into this, what option do I have? How I can I some custom recovery such as TWRP?
Also, I saw a youtube video where a gentleman shows how to completely reset from Recovery mode (hold power button and press up volume key), but that doesn't seem to work for me.

Yes, that's the bootloader. Google 15 second adb install xda and install that. Then download the latest version of this http://techerrata.com/browse/twrp2/mako
Rename it recovery and put it in the same directory as fastboot.exe which will be installed with the 15 second adb install
Open a Windows command prompt in the same directory as fastboot and then with your phone connected to the pc and in the bootloader type the command in the command window
fastboot flash recovery recovery.img
This will instal twrp to your phone

My Biggest concern right now is not TWRP. I need to somehow get the machine to boot. It is stuck in those 4 circling things, and I need to somehow get the OS to work (or re-install if needed).
I am able to get to recovery where I see options to 'apply aupdate from ADB,' 'wipe data' and 'wipe partition'. I have wiped off everything, now I need to somehow get OS to install, and I don't know how. I tried using 'adb sideload 'image-occam-ktu84l.zip', but it fails.That file was extracted from occam-ktu84l-factory-0d3fd624.tgz from Android site.
Update: Great, now TWRP is installed. What next? I don't want CM at this point. Just stock Os. How do I get on to the machine?

I installed both TWRP and CWM alternatively, installed factory images using flash-all.bat, install CM11. But in both cases, 1. factory image : The system get stuck in boot mode where those 4 circles keep rotating around each other, 2. In CM11, the arrow keep rotating indefinitely.
I don't know what else I can do.
Any pointers? Thanks in advance.
I am beginning to suspect hardware malfunction. In which case, is there a log somehow I can see?
As an Aside: 1. Adb refuses to see the device in fastboot mode. Not sure if this is an expected behavior. Fastboot can.
2. Stock Android USB Drivers never work. I had to get the WugFresh Development drivers.
This is Windows 8 environment.

Yes, after locking (fastboot oem lock), bootloader the status says locked and I no longer see that unlocked icon when booting.
- At the moment I have CWM, and I see advanced options to format different folders which I have already done. But what I am not able to do is to use adb to copy the image-occam-ktu84l.zip to sdcard. Only way I have been able to install any zip is using sideload. Is that normal? I wonder if I am following right steps to begin with.
- Also, are there tools that can run and check if emmc has no bad sectors etc?
- In CWM I formatted whole log of folders, and now when CWM boots, it can't find /cache/recovery/* files. Which I take as a good sign - since old stuff is now gone. From here I don't know how to proceed. Any help - very thanful.

You have to be in recovery to run adb commands. The bootloader is only for fastboot commands. Try pushing while you're in recovery, not the bootloader.

Fastboot mode issue in MiA1

Hi.
Recently I decided to flash lineage os 15.1 on my MiA1
For that I have downgrade to Android nougat.
After downgrading I booted my device.
After setting up device I booted device in fastboot mode to follow further steps like flashing TWRP and all but the problem is my device goes in fastboot mode and it is not identified by abd and after that it is automatically getting restarted and is not holding in fastboot mode.
Please help??

Odd issue. What are you using to flash? If you are using XiaoMiFlash.exe, you'll want to try the (THIS WILL REMOVE ALL YOUR DATA) "clean all" option. Please note that this removes all your data.

I have used MiFlash tool for this and now My device automatically reboot from fastboot mode so I am not able to use adb as well to flash rom or twrp also Now MiFlash tool is not recognising the device.

It should boot if you've fully flashed it and cleaned the user data partition. If it still isn't, you'll want to wait for other members with more experience in bricks to chime in.

My device is booting up without any problems.
But the problem is bootloader is still unlocked. So i am not able to update via OTA.
And as the device does not holds in fastboot mode so I am not able to do other flash work.
Is there any way I can share a video of my problem with you?

Oh. If it's booting up fine, then you shouldn't be worried too much.
If it keeps restarting in Fastboot mode, it could be a driver issue which is preventing your PC from recognizing your device and vice versa. I'm on Windows 10 which installs drivers automatically so I've never had experience with it.

If i boot in fastboot mode the device should be in fastboot mode till power button is not pressed for at least 10 seconds.
But in this case it gets switched off.
I have not connected the USB to pc and nothing else.

I think that's expected behavior? If it doesn't recognize itself being connected to a device, it'll exit fastboot mode.
I think you need to connect it to the USB cable and into your PC for it to not restart/power off.

No when I connect it to pc at that time also same happens.
Previously when booted in fastboot mode it will stay ther by the time juice is out.

Yup. I just tested it out. It looks like you're right.

So do you know how can I help myself out?

wait.. what exacly did you do when you booted into fastboot? did you type "adb devices" or "fastboot devices"? also, try rebooting into fastboot mode by typing "adb reboot bootloader" in cmd, with your phone plugged into your pc, and with the proper platform-tools installed. it shouldn't really go away from fastboot mode like that.

Hy man, I know basic of adb and I use cmd "adb devices"
My device is recognised when it is on.
I can also give various cmd like boot in recovery or fastboot mode or reboot and the device follow the instructions.
Please see the video that I've shared.
Once fastboot mode is on the device is automatically restarted in about 10 to 15 sec and within this time MiFlash tool or adb cmd prompt bot does not recognise my device.
I have tried to flash OTA via adb side load but it is showing error.
Help me with your input!

Your device doesn't get detected in your CMD prompt when it's in fastboot AND you type "fastboot devices"?
If it doesnt then you might have flashed something incorrectly.
Also, make sure to have your android drivers up to date in your pc. It's very, very likely that you don't have them installed on your PC, or they are outdated. See this: https://developer.android.com/studio/run/oem-usb.html

I have faced this issue. Yesterday i dirty flashed a custom rom. but i forgot how to dirty flash. i just simply flashed the rom and restarted the phone. it was mandatory to flash custom recovery and gapps after flashing a rom dirtily or normally. but i didn't. After the reboot completed, i remembered that i didn't flashed the twrp and gapps. So, i go back recovery mod, guessed i could flash twrp now. But i didn't see any custom recovery on my phone. But the phone boots, and i can use the phone. Still, i'm on that phone, while i'm typing this comment. i didn't lost my data cause i flashed dirtily. But the problem is, as i didn't flashed gapps or magisk (for root access), now i can't use google apps like, play store, and more. As i don't have root access on my phone so, i can't run flasify, to flash custom recovery. neither i can run other apps that need root. As i didn't flash custom recovery, now i can't flash gapps, magisk and whatever that needs a custom recovery.
I told some rom porter about the matter. They told me to flash stock rom. So, i was trying to flash stock rom. but flashing stock rom requires a fastboot mode. But my fastboot logo doesn't appear and it's blank. I told this to a rom porter. But he said, He doesn't know about that and he can't help.

Unable to enter fastboot mode after flashing

I have unlocked my phone, hoping to find a fix to USB external camera not being recognized. As a consequence, I am not able to update my system through OTA. Moreover, I am no longer able to enter fastboot mode. Whatever key combination I tried, my phone will do a normal boot. When I power up or I press volume - I only end up doing a normal boot or powering off. If I press all 3 keys together I get into the e-recovery boot, which fails. I have only been able to boot into TWRP after downloading a system update and choosing to install it. With this procedure, the update will not be installed, but I will boot into TWRP. From here, if I choose recovery, I do boot into fastboot, but my fastboot is not recognized by my computer, as it was before. Running either ADB or Fastboot will not reveal any device connected.

When you use key combinations, you must shutdown your phone first, not reboot or you can boot into system, make sure that usb debugging is turned on, open adb and type "adb reboot bootloader".

Thanks, I followed your instructions but with no success. As soon as I plug into USB it will power on and go on with a normal system boot, no matter how quick I am in typing the command "adb reboot bootloader", which invariably returns "no devices/emulators found", or whether I press the volume - button or not. This also happens when I am in the charging screen (not sure whether this also equals power off).

No, you need to boot to Android to use adb.
Is your device bricked or stuck in a bootloop or something?

I wouldn’t call it properly bricked, inasmuch as it is actually doing its job. However, It does some strange things: it gets the OTA updates, but when I click on Download and Install, it restarts in the TWRP menu (which I cannot otherwise access. I have 2 TWRP apps installed, which don’t seem to be of any use: official TWRP App and TWRP Manager). When I am in the TWRP menu, I can choose to restart in the bootloader. However, once there, with the green window telling me that my phone is flashed, the phone is still not detected by ADB or Fastboot commands. I don’t know when the bootloader started to be unaccessible because I left the tinkering a couple of months ago, when I realized that nobody so far has had any success in getting a P10 Lite to work with a USB Endoscope.

Thats normal behaviour, when you have a custom recovery installed and do anything in the stock recovery then it boots you into the custom recovery, it should also boot to TWRP when you do factory reset in the stock recovery. And when your phone isn't detected by fastboot then its probably a adb and fastboot installation issue on your PC, type "fastboot devices" to see if it detects your device. And what do you even want to do in fastboot?
Also are you in Nougat or Oreo?

I am not too sure to have any working recovery at all, right now. If I press all 3 buttons, I get into the Huawei recovery mode, which fails. I am on EMUI 5.1.1 (Nougat) and would like to install a stock recovery to Oreo. If I am able to get to a working bootloader mode, I would like to install this file which seems to be a stock recovery with Oreo (WARSAW L21C432B182_EU_SERVICE_ANDROIDHOST.RU.RAR). Otherwise, I will buy a MicroSD card reader and try copying this installation to the card, which, according to this video (https://www.youtube.com/watch?v=0vDgDXePAR4&feature=youtu.be) should be the last resort, if everything else fails. I would be perfectly happy to return to a working and updated standard EMUI. I'm told that if I installed the OTA version this would not be working correctly on my my phone. According to an app called Rootchecker, my phone is not properly rooted either, but there are a lot of crappy apps out there, so I don't know what to believe.
BTW: I don't believe there is any problem with my adb fastboot installation (on MacOS). It was working earlier on. When I type "fastboot devices", it returns: "waiting for any device"

I still can't uderstand you. Can you boot into Android or not? And Does TWRP work? When you device is softbricked, what did you do to brick it?
At one point you say that you can access fastboot by choosing reboot to bootloader in TWRP and then you say that you have no working recovery at all.
Anyway I can't help you with the fastboot thing then and that file isn't Oreo it's an old version of Nougat, B360 and up is Oreo and also B321 witch is Oreo Beta. You can only flash image files in fastboot anyway as that file needs to be unpacked and put on the dload folder on your sd card.
When you want to get to Oreo you can either use service roms from this thread https://forum.xda-developers.com/p10-lite/development/service-rom-b362-c432-upgrade-o-o-n-o-t3813946, you need to copy the two zip files into the dload folder in your SD card. You can also use HWOTA but that wouldn't work since fastboot isn't working for whatever reason. Or when your custom recovery is working you can use HuRUpdater. But you need to be on the newest version of Nougat B210 or B209 to update as otherwise you may brick your phone.
