[Q] Stuck on "No Command" after trying to update to 4.4 - Nexus 10 Q&A, Help & Troubleshooting

I got a notification that I could install the 4.4 update, so I went ahead with installing it. After downloading the update, I got the android with a red triangle with an exclamation point in it, saying "error." I tried holding down power + volume up + volume down and selected "start." After that, I got a "no command" message with the android with a red triangle and exclamation point. I cannot reboot into recovery; trying to do so just brings me back to the "no command" message. I tried "rebooting bootloader" but that also just brought me back to the "no command" message. Powering down the device and restarting it also just brings me back to the "no command" message... If I just leave it on the "no command" message for a few minutes, it attempts to reboot but always just ends back up on the "no command" message. I don't know what to do.
Other information that may be relevant is that I was unlocked and rooted on 4.2, but updating to 4.3 caused me to lose root. I had TWRP as a custom recovery when I was on 4.2, but honestly am not sure if it stuck when I updated to 4.3.
Can anyone give me ideas for how to fix this and get my N10 back up and running? Thanks in advance.

Use a toolkit or fastest to flash stock image. Flashing recovery might work as well.

the android community would love the factory image you have received

Please get the OTA file for us all.

I'd love to upload the 4.4 factory image, but I cannot even boot up the device. Later I'm going to try using the wugfresh toolkit to flash the 4.3 factor image and see what I can do from there.

If possible could you flash a custom recovery first, and backup the /cache partition? :laugh: :good:

I'm running into this problem as well. It's driving me nuts. I've flashed both the 4.2 and 4.3 factory images and no matter what I do I can't get to recovery. I either get "no command" or just the error Android with no text. Any tips would be hugely appreciated.

I was finally able to fix my N10, so hopefully this can help you, too. I downloaded the latest version of Wugfresh's Nexus toolkit and was able to flash the 4.3 factory image. When I first did it, I still had the red exclamation android with no text, and thought the install failed, even though the tool said it was successful. (I should have been more patient and let it reboot on its own.) So I did the process over again, redownloading everything. After that went through, I still had the red exclamation android with no text, but just let it sit for about 30-60 seconds and it rebooted on its own. FINALLY, it booted up and everything works fine. I'm running stock unrooted at the moment. Now, the problem I have is that I cannot get the 4.4 OTA anymore!!! I guess I will have to keep waiting for the OTA.

Thanks for the follow up. Turns out, I'm just dumb. I was getting the Android with the ! most of the time, and "no command' for a little while, even after using Wugs to flash factory images and even doing it manually. The "no command" was most likely just a bad flash. The rest of the time there was nothing wrong at all. Turns out, to get to stock recovery you just have to tap Power + Vol-Up while at that 'Android with a !' screen. I was expecting it to go straight to recovery. Now I feel foolish.
EDIT: Then I just sideloaded the update from stock recovery. 4.4, woot.

Stuck on "booting recovery kernel image"?

Was fiddling around in the settings, hit check for system update, installed a >20mb update, and now my tab is stuck on the Acer boot screen with the text "booting recovery kernel image" in the upper left corner.
Anyone else had this problem?
Should I leave my tab for a few hours and hope it boots, or force a restart?
update:
held down the power button for about 5 seconds and reset with no problem.
"Update failed" window on reboot.
System update 4.010.13 (14.49) update still available when I go to system update->check now.
Currently running build 4.010.10
Does anyone have info on update 4.010.13? Hesitant to try and install it again.
You have to unroot it then install the update then root again.
Sent from my SPH-D700 using XDA App
how do you want to unroot if you can't restart?
i hope you have an external sd-card
dl one of the stock 3.1 roms and extract the update.zip (eventually you have to use the un encryption tool available in dev).
put the update.zip on your external sd-card
hit volume- and power simultaneously.
if cwm is installed you will see the cwm menu. if it is not installed it will start with the update.zip and reinstall you system, without root and cwm.
My tab is stock and unrooted but ill try the update again.
Tried to install the update a second time.
Tab restarted then displayed the same "booting recovery kernel image" screen again, but this time only for three or four seconds.
Then went to a screen with the green android guy, a bunch of turning gears, and a progress meter for a little while.
Rebooted and displayed a window "apk process installer" and some text. Looks like it worked this time.
Good to hear it worked out. Not many people have had issues with installing these OTA's while rooted and on stock. I'm sure it was just a fluke. Nevertheless...

[HELP] Failed 4.4.3 OTA Update

Just received the 4.4.3 OTA Update, downloaded it and then followed instructions that required me to reboot in order to install the update. After rebooting, I got onto the screen where the green android Logo was there and the update was getting installed. The progress bar indicated that most of the installation was done when suddenly the progress was replaced with an "Error!" message just below the green Android alien. I tried to switch off the phone and switch it on again, but now the phone doesn't start, the Google Logo shows up but after that the screen is just blank. Would appreciate any help on get this to work. My phone is not rooted and I don't have any custom ROM's installed on my phone just FYI.
I've also been able to take it to the screen where you have the green alien and then a few options that we have to select with the volume buttons ("Start", "Restart Bootloader", "Recovery Mode" and "Power Off" ). Selecting Start from here has the same effect as before the screen stays blank.
Also tried getting into Recovery Mode, but that just gives me the robot with "No Command" being displayed on screen.
Would appreciate any help on getting my phone working again!

Flash the 4.4.3 factory image in fastboot. If you're worried about losing data then flash each piece individually and don't flash userdata.img

Can I still do that even if USB debugging is not enabled? What would be the best way of doing this? Not worried about data, as I had everything backed up and I've already tried a factory reset and that didn't do anything.

[Q] Nexus 4 doesn't switch off. Keeps starting again.

I was running Android 4.4.4 on a rooted Nexus 4. I wanted to upgrade to Lollipop. The only way I could think of doing it using the WugFresh toolkit was to unroot + flas stock option and choosing lollipop. It kept throwing an error saying "Unable to allocate 890.... bytes". It suggested to enable force flashing and try again. I tried that and since then it kept getting stuck at load screen. I couldn't even boot into recovery (The dead android with red exclamation mark). I then tried to unlock the bootloader again but for that, the first step needs me to be in bootloader mode. I am trying to switch off my phone but keeps getting powered up again. I a unable to switch it off.
Any help would be appreciated. This is my first post on xda so unsure about the standards to follow for posts. Let me know if more details are needed on this or this is the wrong place to ask etc...
This is solved
I pressed power button for 15 seconds and then I could get into bootloader so I am good

5.0 bricked my phone

Saturday evening I got a notification saying 5.0 lollipop was available for my s5 so I eagerly downloaded the update. During the update my phone froze and crashed (had this happen twice earlier in the day) and it rebooted to the update screen. Once the update finished installing the phone rebooted like normal and sat at the verizon screen for about 2 minutes before crashing again. This caused the phone to enter a boot loop that ended up making an open padlock symbol appear on the start screen. After this appeared it took me to a screen that said "System software not authorized by Verizon has been found on your phone". After getting this error I tried using Odin and Kies to reinstall 4.4 on my device. The install was successful but after the phone booted it was freeze and crash again leading to another boot loop and a "recovery booting" message in the top left screen. It now either boots back to the System software screen or loops until it hits the recovery menu. Is there any way to fix this or did Verizon brick my phone?

Still boots with the custom rom padlock and freezes on the verizon screen
Try pulling the battery. I've read where that's helped some people get it to boot.

Ok, so I am safe now. I was able to flash a stock NK2 Kernal.
Pull the battery on the phone. Hold down Vol. Down, Home, and Power and go to download mode. Plug in the phone, and open Odin. Flash the kernal.
Reboot and you should be ok. This just worked for me.

If Kies doesn't work, try Verizon Update Tool. It also has a repair tab and may help you get back to stock.

Instead of flashing only the kernel, flash a stock, unrooted retail version of KK 4.4.4.

This worked for me as well, thanks! For anyone that wants to know, I used "NK2_Stock_Restore.tar.md5" specifically. You can get it from this thread labeled as "NK2 Stock Restore".
