[Q] Nexus 10 UnRoot Problem - Nexus 10 Q&A, Help & Troubleshooting

I am using Nexus Root kit to unroot my device. However I totaly forgot that I rooted it and tried to update to 4.4 kitkat. I got the error and when I try to boot up, it says no command. THere is no way past that screen. So in the toolkit i flash stocked and unrooted the device, but then i have to relock it. But to do so I need usb debugging enabled which is impossible to do without being able to boot up device. Now when I boot it up it has the android figure laying down with red triangle saying nothing. What do I do?

That Android guy lying down is fastboot. In fastboot mode you give this command: fastboot oem lock. This will re lock your bootloader. I think you will lose all your data. But I cant remember if it was with unlocking or locking the bootloader.
But why do you want to lock the bootloader?

WOW, I fixed this problem 1 2 3. My nexus has been broken like this for weeks and I went to this link, went to the first step and downloaded from that link. I clicked on the file in there, it was a .exe and it ran something in command promt and the nothing happened. I thought nothing of it. Then after a few minutes I unplugged and gave up. Two seconds later I felt a vibration and the Nexus 10 set up came up and I was sooooo happy. Here is the link, I have no idea what it did, but it fixed it and my boot-loader is still unlocked!!!!! I broke up the URL so I could input the link.

Stuck on "Warning Bootloader Unlocked" Screen after OTA

I bought my first phone from Swappa a couple days ago, and figured I would go ahead and by a rooted/unlocked RAZR M and start messing with ROMS.
When I booted the phone, and got connected to my WiFi network it said I had an OTA, so I went ahead and installed it, (now I know that one should avoid OTAs on rooted phones), but now its stuck on the Warning Bootloader Unlocked screen. I do a hard reset (power + volume up/down), it boots, its done, I unlock the screen, it shuts down, repeat. I can't get it unstuck.
This is my first experience with any sort of unlocked or rooted phone, so I have no idea what I'm doing.
Please help

Which option am I supposed to choose (1-6)? I can't boot into it normally, its stuck on the Warning Bootloader Unlocked screen.

You need to be in fastboot, before connecting the phone to the computer and starting the utility. Brandon gave you the key combo to do it.
I got it fixed, and it upgraded to 4.1.2, then went to install Eclipse ROM, the install failed so I hit ++++ back+++++ and then rebooted from the recovery menu, and now it's stuck in the Warning Bootloader Unlocked screen again. Hard reset doesn't work, it reboots back into the Warning screen, and the utility that was posted earlier isn't connecting to recover the device.
What now?

Boot back into fastboot and use the utility again. The utility won't work unless you're in fastboot, and for heaven's sake, make a backup of your stock ROM, before flashing anything new. If you had a saved ROM, this would be easy. After Eclipse failed to install (it has been well documented that a straight install of Eclipse through TWRP or CWM usually won't install), you could have easily gone to the main menu in recovery and clicked "restore" and restored with zero issues.

always make a backup man, safe yourself some time.
I can get it to boot into Fastboot no problem, but when I go to run the script its not recognizing that the phone is connected. The phone says "Connect USB
Data Cable" even when its connected. I'm not sure which side is failing to see the connection, the phone or computer.

hi, can you tell me how did you get out from the stuck mode, i am in the stuck mode now..

locked bootloader wont unlock

Hi everyone. Here is the deal im having with my nexus 7 (not the 2013 model) with jop40d.zip. The person I purchased from didnt tell me it was soft bricked. It seems as though he tried to root it but failed while at the same time relocked the bootloader. So I've tried almost everything in my mind to get it back to normal. It wont let me adb sideload the stock rom it says "installation aborted" or any other rom. Also when i boot up it goes directly to the bootloader which gives me the options start, restart bootloader, recovery mode, power off. start obviously does nothing. restart bootloader just for some reason turns the device off, recovery mode takes me the caution sign where i can adb sideload or factory restore. factory restore hangs and doesn't do anything then shuts off. adb sideload always fails when loading up the zip files. i factory restored the cache. I'm not sure what to do anymore. I spent a fair amount of money on this device but now it all seems like a mistake. Can anyone who has fixed this issue help me out? I would deeply and greatfully appreciate it.
-Cheers

also I wanted to add. I have the android sdk installed and all drivers installed properly. as well as adb/fastboot.
Stop trying to use adb, follow the sticky at the top that says flashing a factory rom using fastboot/return to stock. If you can't type fastboot devices and get a serial number return then the drivers are not installed properly.

Stuck in fastboot

Hi, everyone!
Yesterday I wanted to update my rooted Nexus (2012, Wifi) to 4.3 Android. So I tried a "Back to stock" using Nexus Root Toolkit. After that the Nexus is stuck in fastboot mode, if I turn it on I see the Google logo, but green square with the START appears and the only option that works (other that POWER OFF) is Restart bootloader.
I tried many of the methods (hard reset, fastbooting an img using commands) I found but nothing seems to work, it's just stuck
Cheers
Try with you nexus toolkit to unlock first. This worked for me.

[Bricked?] Can't get to bootloader after trying to unlock with NRT

So I have a nexus 10 32gb that I got yesterday that I updated to 4.4.4 and I wanted to root it so I could get some apps that I love to use. Here's what happened:
Everything was going smoothly with nexus root toolkit. I set up adb and all of the drivers. Everything with that was working and I made sure to check nexus 10 with 4.4.4 in the drop down. I press the unlock bootloader button and the device says it's going into bootloader mode, but it just goes to a black screen. Then a message pops up saying I have to factory reset if i'm on 4.4.4, but that never shows up on the tablet, so I just hit OK. Then the device supposedly reboots, but now it's stuck in a bootloop and whenever I hold down the buttons to go into the bootloader the screen will turn black and the device will vibrate once after I hold the buttons for a while, then it tries to reboot again and gets stuck bootlooping. Then I try the factory reset method through the nexus root toolkit, but fastboot fails to see the device since I can't get it into the bootloader! It also doesn't show up as the correct device when it is bootlooping and connected to my computer.
Am I scewed if i can't get to the bootloader? I don't know what went wrong. I just got it yesterday and assumed it would be super easy to root since it's a nexus device. :'(
Any help/ suggestions would be great.
You are correct, nexus devices are super easy to root especially without a toolkit, most rooting issues I've seen on any nexus device has been due to the use of a toolkit so I would advise not to use it.
Currently you need to get into bootloader so you can flash a custom recovery with fastboot and then flash ROM of choice from there
Try adb reboot bootloader while in bootloop but I have a feeling this won't work. So if not try powering on holding volume down, even try with volume up, just keep trying button combos to get it to boot into bootloader.

Try power and both volume buttons at the same time if you haven't already.

I have actually been trying that. I just let it die while it was bootlooping, so hopefully when it gets a little charge I can try to get it to go into the bootloader again. I have a feeling there's a bigger issue than that though.

Bootloop and cannot boot into recovery

Hi Guys,
My nexus 6p is running stock firmware with no root or any custom rom or recovery.
Suddenly, while i was browsing the internet on my phone, it restarted and went into bootloop through the google logo.
I tried to boot into bootloader and then tried to go to recovery mode from the bootloader but it went again into bootloop.
I then tried to download the latest image and tried to flash it but was surprised that i cannot unlock the bootloader except from inside phone settings (if it was working) which is very inconvenient.
Any thoughts as recovery mode is not working to be able to reset to factory settings and cannot flash any rom or original firmware as it's locked.
Are you saying that you did not have OEM Unlock turned on or have USB debugging enabled in developer options? Is your phone recognized by ADB when you are connected to your PC? When you enter the Bootloader, can you select ADB Sideload with bootlooping? I have been trying to help a couple of people with this issue for the past few days Also, when you enter the Bootloader does your 6P show DOWNLOAD MODE is Disabled?

Try this:
Press and hold the POWER BUTTON + VOLUME UP and continue to hold them. Watch the screen. Does it still continue to bootloop or does a screen show up that says "NO COMMAND"? If the NO COMMAND screen is displayed, let your device sit without doing anything. There are some devices that have sat at this screen, rebooted on its own and booted back into the OS. Let me know what happens.

Yes. i left it as you mentioned and it went into bootloop. Even the one time i managed to get it in recovery mode and made factory reset and wipe cache partition. I did not get it to be detected by ADB as debugging was not enabled in the setting menu.
This recovery mode is really useless if you cannot start the phone. Its supposed to be RECOVERY mode but its completely useless.
Previously, you could just unlock the bootloader and flash new image. Now it must be enabled in the setting in a phone that does not even work.
The only option you have with a locked Bootloader is to attempt to ADB sideload a zip or OTA and that's only if you could select adb sideload from recovery. When you open the Bootloader does your device show that DOWNLOAD MODE is DISABLED? Also, have you checked to see if you can issue any fastboot commands while in the Bootloader?
Sorry, I asked about the Download Mode showing disabled again. I've read so much about this and so many threads I forgot. Try this for me:
Open the Bootloader
Type this fastboot command:
Fastboot oem ramdump enable
Fastboot reboot Bootloader
Power down
Power up to the Bootloader
Try selecting adb sideload again and see what it does.

You are asking the same questions again. YES, download mode is disabled.
after the first command, it tells me "locked device to enable ramdump"
I tried adb sideload but did not work because its not enabled in the phone settings as i already mentioned before.
I apologize for asking the same questions. I got confused on which thread I was posting in. I have been trying to help someone else with the same issue.
Sent from my Nexus 6 using XDA-Developers mobile app
Adb sideload won't work in bootloader mode, only in recovery. The only thing that will work in bootloader mode is fastboot but seeing as the bootloader is locked (with no way to unlock it) you can't use fastboot. If you can't get into recovery there's nothing you can do except send the phone for repair.
But how can anyone troubleshoot any phone if the OS is not working. This new way of security is simply impossible.
So if the OS fails like my case, i am screwed.

I'm not sure what you mean by new security, this has been standard fare for some time now. I'm sure if your phone was stolen you'd be thanking this security feature because it'd mean that the thief couldn't possibly access your data.
People in the know usually go into the settings menu and tick the "allow oem unlocking" box even if they don't plan on unlocking the bootloader at that time, there's a slight security risk but it's insurance against situations like this.
And what you're saying isn't entirely true; even if the OS fails the phone can usually still boot into recovery which would mean being able to revive it via adb sideload. What you're experiencing is relatively unusual, not being able to boot into the recovery as well as the OS means you're basically screwed.
If there's anything to take away from this it's that electronic devices fail sometimes. If you can handle the security risk it's worth ticking that box in the settings menu, or even completely unlocking the bootloader, to give yourself some insurance against these rare situations.

My phone just did the same thing yesterday morning. I'm currently waiting for Hauwei support to get online because Google wont do anything for me since it's been about 13 months (Google only offers a 12 month warranty). Hoping for the best, but without being able to access Recovery makes me very doubtful.

You both might want to take a read of http://forum.xda-developers.com/nexus-6p/help/figure-brick-t3450921 - it has many people who have experienced the issue you both have. tl;dr - you'll probably need to contact goog/huwaei for a replacement.
Had the exactly same issue the day before yesterday, tried every possible way to flash different versions of images, none worked. My warranty expired 2 weeks ago, so both google and huawei told me that I am on my own for this.
Wow.. I feel for you all. I've had the exact same thing happen some weeks ago, phone freezing, then reboot, then couple of days later bootloop, then able to flash and reinstall, then after one final bootloop with the phone unable to 'take' the flashing through recovery, etc, etc. I've been playing with xda since the days of Froyo and that was the first time I had to send a phone back under warranty.
I was just about to try to manually rebuild the whole partition system at the block level but I'm glad I could send it for repairs. You might have a chance if you go as low as that. Good luck
* edit * I got the TWRP to stick by flashing it in Fastboot a couple of times in a row at that time, then I was adapting a Linux guide on reformatting and repairing drives partitions and all that through an adb shell.I did not get it to work yet before sending it, though.
