Hi
I rooted my nexus 10 some months ago. All worked fine until yesterday. I wanted to go back to original firmware and used the WUGs nexus root toolkit to download 4.4.3 version and flash it. But afterwards the tablet doesnt boot anymore. Google logo appears and then the circle thing never goes away. I searched many threads, and all base on going into fastboot and flash again, but thats the problem. I cant get into fastboot. The usual combination (Power and vol+ and vol-) doesnt work! I tried many other combinations with different timings, longer press only vol+ and power ...., I always get to google logo after it vibrates.
Is there any other way to get into the fastboot mode ?
Can I connect it to the computer and interrupt the boot process when I switch it on via the PC?
thanks in advance
regards
Erich
Try to connect it to PC with original usb cable and run "adb devices".
If you see Nexus device, you can try "adb reboot recovery" and upload a ROM to /sdcard with "adb push" for flash it.
Hi
Thanks for your relpy.
But thats the problem, even if I could upload a file with adb, which is not working, how would I flash it if I cant get into fastboot or recovery mode ???
thanks anyway
regards
Erich
I think what patzzz is saying is that it depends on your bootloop, often is the case that when someone is in a bootloop the kernel does initiate and adb is functional. Not always but at times for sure.
So if so you can attempt
adb reboot recovery
Or
adb reboot bootloader
If the above doesn't work than you will have to continue trying to boot to bootloader manually with key presses (which I believe is power on while holding volume down)
Best of luck!
Hi
Thanks for the tip. Unfortunately it doesnt work. It made a batch file which calls adb devices and adb reboot bootloader in a loop, so it can send it to the device if it is found, but the tablet isnt regonized, tried some reboots and no luck, adb cant find it )))-:

It seems a brick, but you can try using fastboot command instead of adb:
Code:
fastboot devices
fastboot reboot-bootloader

I suggest you do a factory reset from the stock. You have gone back to stock firmware so you should have stock recovery. I had this happen once and this work for me.
Hi
I will try it with fastboot too, maybe it works....
How can I do a factory reset without recovery mode ?
thanks

1.If your tablet is on, turn it off.
2.Press & hold the Power, Volume Up, and Volume Down buttons at the same time for several seconds. You'll see the word "Start" with an arrow drawn around it.
3.Press the Volume Down button twice to highlight Recovery mode.
4.Press the Power button to start Recovery mode. You'll see an image of an Android robot with a red exclamation point and the words "No command."
5.While holding down the Power button, press the Volume Up button.
6.Use the volume buttons to scroll to "Wipe data/factory reset," then press the Power button to select it.
7.Scroll down to "Yes - erase all user data," then press the Power button to select it.
>>2.Press & hold the Power, Volume Up, and Volume Down buttons at the same time for several seconds. You'll see the word "Start" with an arrow drawn around it.
Thats the problem, it doesnt work! Tried it a dozent times, only Google logo appears.....

I unlocked the bootloader and flashed a custom recovery. I then rebooted the device. Now it is stuck at the bootloader (white Google logo on black background) and I can't get it to do anything else. I've rebooted it a bunch of times including with the vol + and vol - buttons held down to no avail. I've also let the battery run out and then tried to boot it up again and the same thing happens. adb nor fastboot see the device and it doesn't show up in the logs on my machine (Mint 13) as coming online at any time.
Most of the times I reboot it with the power switch it reboots to the Google logo even without me letting go of the power button. Sometimes I can get it to fully power off but I haven't figured out what combination of vol keys and reboot does that.
Anyone have any ideas what could be wrong? Any help would be much appreciated!
You are not bricked if you can still get into the bootloader.
Download the factory image from here, and flash it with fastboot. If you don't know how to do that, read this thread.
I wish I could get fastboot to see it then I could definitively flash that img.
I can't get into the bootloader and can't get fastboot or adb to see it. It's stuck at the Google logo now and when i hold the power key it reboots back to the Google logo with the unlock logo at the bottom.
Thanks for the help
You've tried holding volume down+power for 10+ seconds? That should power off the device, then hold both vol up+down down and power up
Ya I've tried to hold vol + and power for 10+ seconds and it reboots back to the Google logo even if I don't off the power key. Same happens with all the other combinations of keys being held with the power button. I can't get it to turn off now unless I let the battery die
Press and hold power till screen goes black. Then quickly press power+volume down and HOLD.

Tried that and still stuck at the Google logo. I have to go to work for a couple hours and then will hack on it when I'm back. Hope I don't have to deal with Googles rma process seeing how disorganized the rest of that company is

No luck with any button combos but the vol + and power actually turned it off. All out of ideas over here. I'm thinking it really is bricked
I'm in the same spot. I can get it into recovery occasionally but once there it locks up after trying to flash or clear the cache.
I'm wondering if a contributing issue is CMR v6.0.0.6? I updated it from 6.0.0.4 that was running fine. But no fastboot or adb so that is doubtful.
This is frustrating and not a great start with this N7.
thank you

this worked. you have to be fast. as soon as screen goes black release power button then quickly, very quickly repress along with vol up and down.
You will still be able to get into the bootloader! Force kill the tablet by holding the power button for ages. Then hold volume up and volume down and the power button together, which will boot to fastboot.
It looks like a CWM bug as I feared. Anyone in the same boat try here - http://forum.xda-developers.com/showthread.php?t=1782932
Nothing has worked and I've literally tried everything that those three buttons can do. Thanks again for all the help guys. Had a great time trying to resurrect it but guess it's time for it to go back home
Just as I suspected. Google puts out buggy junk once again.
I just wanted to report a similarly event. I have a rooted, unlocked Nexus 7, with TWRP recovery. I have previously rebooted without issue. Tonight I booted into bootloader mode to check something and the hit power button to choose start. I got stuck on the boot logo. After finding this thread, I started with the simplest combination and held power button until screen went dark, then added volume down and once again in bootloader. This time choosing start led to a regular system boot. It's as if the device froze and needed a hard reboot.

I was attempting to boot into recovery and kept getting the 'Google' logo (I am unlocked/rooted with twrp recovery). I wasn't aware that one had to be plugged in via usb in order to *not* hang....
Any way around this?
Once I plugged it in and attempted to boot into recovery it worked fine.
I had a similar issue after using the Nexus Root Toolkit to flash to nakasi 4.2 with CWM recovery - just got stuck on the nexus boot screen, flashing in a loop for over 15 minutes.
I ended up powering down the device, holding power for about 5-10 seconds - then QUICKLY holding both the power and volume up+down keys, it then went into the fastboot screen.
After it was there, plugged it into my PC.
Now, this should work for you - assuming you have all the fastboot/usb driver stuff installed.
I extracted the contents of nakasi-jop40c-factory-6aabb391.tgz into the same directory as the fastboot.exe provided by WugFresh with his Nexus Root Toolkit (google search or xda search for this if you dont have it, i dont think i can post links due to my low postcount) - typical filepath: C:\Program Files (x86)\WugFresh Development\data
By the files in there, I mean drilling down inside the tgz to where the image files were inside so that files like bootloader-grouper-4.13.img, image-nakasi-jop40c.zip etc were extracted into the directory and sitting alongside the fastboot.exe - NOT in a subfolder.
Once its all here, running flash-all.bat (this is provided by google in the nakasi-jop40c-factory-6aabb391.tgz) from the command line or by double clicking on it from explorer should kick off the process. After about 2-3 minutes, it was complete, and my Nexus then booted up within about 3 minutes after that.
Also worth noting, device remained unlocked, but I lost root/root binary
After unlocking the N 10 and pressing start it is stuck on the "cross".
I go back to the bootloader and I see the following message :
" downloading - do not turn off the target" either connected or disconnected from the pc.
In this case there is no up or down arrows the only choice is "start"
From here to go back to the bootloader without the message I have to press power and both volume.
Then I can select recovery. Once in recovery I cannot get into the recovery menu no matter the way I press power and volume.
If I leave the N 10 on recovery after a while it goes back to the screen with the "cross".
Of course in this configuration I cannot access adb and fastboot.
I would really appreciate the help of the forum members.

You're in a bootloop. While in recovery (without options) you need to press all 3 buttons on top at the same time. Don't hold them, just press them and release. Once or twice should be enough to pull up the recovery options. Once there, do a factory reset and you'll be all set.
Mine got pretty hosed when unlocking too. Couldn't even get into recovery. Had to use fastboot to flash recovery.img, then I could get into recovery and do a factory reset.

Thank you very much (I also press the right button).
At first I wanted to reply that even this option did not work though I tried it more than once. Instead of replying to your post I decided to give a final try and it worked. In my previous attempts I was obviously taking a nap on the 3 buttons.
Yes, I know, everyone knows how to enter safe mode, bootloader, and recovery.
I found there are some inconsistencies to entering and using recovery depending on your which software you are running. In addition there are multiple ways of entering stock recovery.
Also I always see people asking this question because somehow the keypress order is not intuitive.
Entering Safe Mode
Tablet booted and running Android
Press/Hold Power button until power menu shows up
Tap/Hold Power off option
Choose OK to reboot in safe mode
Tablet powered down
Press/Hold Power button until Google screen shows up, RELEASE Power button
Press/Hold VolDn until Android has booted up
If successful, you will see Safe mode overlayed on bottom left of screen.
Entering Bootloader (ie fastboot mode)
Tablet booted and running Android
From adb
adb reboot bootloader
can also choose recovery from menu after bootloader comes up
From app
Use Quick Boot from Google Play
Tablet powered down
Power+VolDn while booting to enter bootloader
Release buttons after you see bootloader screen
Entering Stock Recovery
Tablet booted and running Android
From adb
adb reboot recovery
From app
Use Quick Boot from Google Play
Tablet powered down
Power+VolUp while booting to enter recovery
You can release buttons after you see Google on screen
When Stock Recovery starts you will see the Android fallen down screen
To bring up the Recovery menu
Power+VolUp to show recovery menu
Must be this sequence Press/Hold Power, THEN Press/Release VolUp, release Power
Within menu
VolUp to move up
VolDn to move down
Power to select
In addition, I found an inconsistency with JSS15J stock recovery that wasn't in the JWR66N recovery
While at the Android fallen down screen if you mistakenly press
VolUp
instead of
Power+VolUp
you will still get the Recovery menu.
However, VolUp will no longer function. It will instead become a toggle for switching between the Recovery menu and the Android fallen down screen
Android fallen down screen
VolUp to toggle recovery menu
Within menu
VolUp does not work since it toggles recovery menu
VolDn to move down
Power to select

I don't remember if there are two images one with and one without the triangle. I think I've only seen the image with the red exclamation point.
I've never seen anything to indicate the red exclamation mark is something you need to pay attention to.
Now if you apply an update and there is an error, then that is something I would pay attention to.

It doesn't load the stuff you added.
It is similar to safe mode on a PC, used to diagnose whether the issue is in the stock ROM or is in something you introduced by installing some app.
I Have a probleme
since a bought TAB 3 10.1 and it's boot into safe mode i'v restart it and turrn it off the back on but it didn't go what should i do ?

Bootloader
If none of that works, try the command with a dash "adb reboot-bootloader" Depends on your device sometimes, sometimes unplugging your device right after you enter this command will keep it from getting stuck at the boot logo screen. If that doesn't work, hold the power button to power device down and then boot it into recovery instead using the button combo. Then you can wipe cache & start all over again.
I'm not even able to get into Recovery. I can get to the bootloader, then I select "Recovery mode" and it shows the Google logo, but it never goes into recovery. I have let it sit at the Google logo for a couple of hours, and end up just holding down the power button to shut it down.
I have tried Skipsofts toolkit, as well as Wug's, to try to unlock the bootloader. This ends up with the device hanging at the "Unlock bootloader" screen after selecting "Yes". Again, I have left it in this state for well over an hour with no change.
Here's some info on my 2013 Nexus 7:
KitKat 4.4.4
Never rooted
Never unlocked bootloader
HW version rev-e
Bootloader version FLO-04.02
I suspect my Nexus knew I was supposed to go on travel next week and is faking sick.
Any help would be appreciated. Thanks.
Hi guys i have a google nexus 5 and it is locked state. It is getting booted again and again but it jiust reaches google logo and again restarts. Safe boot is also enabled so i cant enter in recovery mode also. Please help me ASAP.
Update: I was able to get it recognized via fastboot and used NRT to flash back to stock under the bootloop option.
Now rooted with factory 5.0.1 !
The way I got it to recognize the tablet was to press the middle part of the volume switch (effectively pressing up AND down volume) and the power button and then the bootloader loaded and I could use fastboot but not adb. I read in another thread about pressing the middle of the sound button. Never heard of that before.
Hopefully someone can help me out.
i updated via abd using the flash all script. Now when it boots up it's stuck on the logo of flying color dots. (yes, I waited 15-20 min at least)
Anyway, now I can boot into fastbboot mode but the computer doesn't recognize it.
If I try to boot into recovery (which I think got corrupted) then I just get the android icon with a red exclamation point.
I have no way to clean anything up cause I can't communicate with it.
Edit: I'm stuck in a boot loop also. If I just let it boot it stays on the logo forever. When I try to turn it off it just reboots to the logo.
If I use the keys to boot to fastboot it just sits there and now I can't even change the option at that point and there's no way to completely shut it down!
Thanks for any assistance you might have.
Pressing both volume buttons and the power button will get you into fastboot mode. It's always the last fallback position and I've never known it to fail. I had the same with a bad flash on Tuesday when trying to solve my wifi problems.
Glad you got it sorted
Thanks.
I was getting to the bootloader screen but couldn't get the PC to see it. I always used to use power/vol down combo to boot into bootloader and didn't even know u could press both vol up and down at the same time.
Or maybe I'm imagining it all.

Hey guys. I just got LG G6 H870 model. Unlocked bootloader without much problems, but issues came later. While being in bootloader I can't do anything, hardware buttons seem to not work. The only way to get out of bootloader is to use "fastboot reboot" command, but that prevents me from getting into custom recovery after flashing it. Only entering download mode works (holding volume up and plugin in usb cable). Non other key combination work until I boot into system.
Can this issue be somehow resolved?
I had similar problem myself with entering recovery more and the reason behind it was that I didn't press the button combo in proper way. what you actually have to do is while you in fastboot mode you press down and hold power button and volume down button. phone reboots after a moment and you should still be holding these keys and when lg logo appears you let go of power button for brief second and then press it back again and then when a prompt on white screen appears just go yes two times and phone shall boot in recovery mode . I had watch a tutorial movie to figure that out. other easy way is just to have adb enabled and reboot it with adb reboot recovery command via USB cable

No, because I had G5 and I know the proper way to do that. Problem is I can hold the power button as long as I live and the phone won't reboot, regardless of pressed combination or power button solo.
and the adb command way ?
Well... Nevermind, turns out vol down button isn't working at all.
still good way around is adb reboot recovery
