Nexus 10 Forgotten Pattern - Nexus 10 Q&A, Help & Troubleshooting

Hi All,
I've got an old nexus 10 which I have forgotten the pattern to.
Originally it had 2 users set up (The Administrator (me) and a Music user for my uni house). Over the holidays I have forgotten the pattern used to sercure the admin account. As the tablet is only used for music now (Google Music) i'm not bothered about resetting it or losing its content etc but was unable to trigger a factory reset from the Music user account.
I've since tried forcing a reset from Android Device Manager but received an error as the Admin account wasn't active and multiple users had been created. To try and rectify this I deleted the Music user and Android DM still didn't work (I also now have a device which I can't use at all as the user without a password has been removed).
I've attempted putting it into recovery to reset it from there but receive a "No Command" error and attempts at using ADB have failed as it is classed as "Unauthorised".
Any ideas on how to reset/remove the pattern. I don't mind erasing all content or attempting to flash a new rom etc but just a tad stuck at the moment.
My google account is active on the device (I can locate it but haven't been able to trigger a ring or reset).
Regards

Since you do not mind losing all data I suggest reset via recovery.
Hold volume up and down and press the power button. Keep all three buttons pressed until you feel a vibration.
You should now boot to bootloader.
Press volume up until the top left of the screen says recovery mode. Press power button to enter recovery mode.
The tablet should now reboot to recovery mode.
Depending on what recovery you have installed, the reset process is different.
On stock recovery (that is id you have not changed) scroll down to factory reset using the volume buttons, select using the power button.
Hope this helps.

When I try to do this I end up with a "No Command" error.

Once I'm in recovery I can easily select the wipe option, but I don't know how to move to the recovery from this error screen?

Was able to fix the "No Command" error by repeatidly pressing the power button and the volume down key.
This got me into recovery properly where I was able to reset the device successfully.

Lovely. ☺

Unlock the "muster"

Hello
i forgot the unlock "muster" not the password this other thing to unlock dont know in english sorry ...and i forgot my google account and now i cant unlock my phone...got any1 a idea?
greetz
Spini
Every idea consists of knowing your google account. Could be possible to retrieve things with adb from 2nt-intit.
and how i do this ? or root it ? but i cant install usb driver or so...
First google how to get/use adb.
Then search how to disable the lock u have.
f.i. sim lock: http://forum.xda-developers.com/showthread.php?t=1409304
Then go to 2nt-init (blue let on startup => vol down) => something with adb
....
....
Could always flash your sbf again check before you flash, should clear it up, or normally you can call your provider if you've forgotten your pin code ask them for a PUK (its basically the back up pin)
Good luck

I think he means the unlock pattern. If you are on stock rom, your only option is to do a factory reset. (see all in defy beginners guide how to wipe data). But then you lose ALL your data.
If you're on CM7, I think you can do it without loosing a thing.
its the pattern...i try to get into the recovery modus yeah i am on the stock rom...but when i try to get into the recovery modus i get a bad symbole..i cant enter it :/
Do you mean the android and the triangle? Volume + and volume - at same time should get you the options,
Having just tried everything I can think of, data wipe and restore for contacts ect, your stuck with a factory reset
teamwork makes the dream work
yeah this..u are right..but how i factory reset it when i cant enter the recovery and i cant enter into the phone ?
From the All-in-one Defy Beginners guide:
How do I enter Recovery Mode?!: With the Phone off press VOLUME DOWN then, while still pressed, power up the phone and leave VOL key pressed until you see a Yellow triangle, once you see this you are in Recovery now press Vol Up and Vol Down at the same time (if you are in Froyo) and the menu will appear, if you are on Éclair the menu should appear without having to press anything.
Turn the phone off, hold volume - and then press the pwr button keep volume - held until you see the

awesome..thank you some much....;-)

[GUIDE] How to get into RECOVERY & Download Mode

I couldn't find any information about how to get into download mode using any method other than using ADB and thougth to myself, "There has to be a key combination" so I had a play around and there is.
DOWNLOAD MODE:
1) Power down the camera.
2) Whilst holding down the Shutter Button press an hold the power button.
You will then see the following screen.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Then just follow the on screen instructions.
In fact, you can do it using the zoom rocker too.
Now, I have been trying to find a combo to get into recovery, I have got it to flash up, but not stay, so it has to be in there, just a case of figuring it out.
UPDATE:
I've figured it out!
To get into RECOVERY MODE:
Make sure the camera is off first.
1) Press the shutter button HALF WAY IN and keep it held in that position.
2) Press the power button until you see it turn on then let it go, but keep the shutter button in the half way position.
You will then enter Recovery.
I keep doing this accidentally, so it wasn't hard for me to find . Must be something about the way I'm holding the camera sometimes when powering up.
I've figured out the combination to get into recovery, first post updated.

nice.. have been trying to figure this out myself,,,
Thanks for this! I'm trying to help someone recover from a bad stock update and we could find the info anywhere on how to get to recovery mode.
Ok guys. I tried all your suggestions and none work. I will tell you which one does. Download quickboot from play store and it allows you to tap on option to go into recovery. Works like a charm. none of this other nonsense.

You actually need to hold longer and it will enter the mode you want.

Galaxy S4 GT-I9500 acts weird

Hi, I have a Galaxy S4 GT-I9500, Not rooted but custom recovery installed, and sometimes I get the SDCard Menu (UP Key - Normal Booting, Down Key - Download Mode) and sometimes it takes me to the CWM recovery mode and Now I was able to remove the cwm recovery mode completely but at random times there are weird black lines on my screen (just like when the tube of a TV bursts) and then my phone turns off. {I am adding the URL of the SDCARD MENU picture and the weird black lines Picture}

Hardware failure. It either the lcd or the gpu that's failing.

Inability to proceed beyond meta mode screen.

I have been trying to hard reset my Lenovo Vibe K5 Note as I have forgotten the login password.
Despite many futile attempts to do it, I am unable to succeed.
While I press and hold on to the power on button and volume down button, screen displays the message
"Have been in meta mode, long press the power button and the normal boot"
After this, I release only the power button while holding on to the volume down button and wait for the next menu to appear.
But nothing happens next. Phone only displays the "Have been in meta mode, long press the power button and the normal boot" and does not proceed beyond.
Kindly someone help me to reset my Lenovo Vibe K5 Note.

Boot Lenovo K5 Note (A7020a48) into Recovery Mode & HARD-RESET
1. First of all, POWER OFF the device. (Keep Pressing Power button. If you stuck on meta mode)
2. Press and hold Volume UP & Volume DOWN and Power buttons together for few seconds.
3. Release the Power button only after vibration and keep pressing Volume UP & Volume DOWN keys until Stock Recovery Mode (in English) appears.
4. Select Clear Data
5. Select Clear User Data. (WARNING : This is a FACTORY RESET. So it wipes Everything. Also maybe your IMEI, MAC ID, Wireless ID can be null or invalid.. DO IT AT YOUR OWN RISK !!)
6. After the wipe, reboot phone and have a nice day.. :good:

Been stuck on this screen for the last 6/7 hours. Pressing power plus volume down restarts the phone then rapidly goes into this screen and starts loading the update. After 100% it stays, nothing happens. The recovery menu never comes. Mine is SM-A205U Full Stock ROM

Restart the phone using volume down and the power button.
After the screen turns off but before it turns back on, let go of volume down and hold volume up instead along with your power button.
Either wipe your phone or format data from there. (Either option will leave you factory fresh in this case)
Unless you wanna use odin to push the update instead of relying on the inbuilt updater.
In which case you hold volume up and down along with the power button before using a computer to do your update.

So it should revert back to its original firmware?
Always wondered about this situation on unrooted phones. It can happen too easily with auto flashing.

It'll clear any data on the partition that may be interfering.
