Yesterday i got a customer with CELKON CT1 TAB running on android 4.0.4, locked out asking for Google user login (resulted in multiple wrong patterns entered to unlock). I searched the web and was able to figure out what to do when this happens. Well USB debugging mode was disabled too. Only way was the RECOVERY mode.
1. NOTE: Apps and app data will be formatted. But data on SD card will be safe.
2. This tab does not have hard volume buttons.
3. Switch off the tab and then hold BOTH VOLUME SOFT BUTTONS and the POWER BUTTON.
4. When you see the android logo. keep on holding both the volume buttons and release the power button.
5. A screen pops up saying something abt encryption and you need to reset to factory settings.
6. Click on OK. The tab does its work and restarts with factory settings and apps.
7. Done. Use your google account to setup the device.
I hope this would be helpful. I spent a lot of time pressing the reset button near the mic, with a paper clip. It simply wont get into recovery mode. Its just like a reset button on a PC.

Hi,
I turned off my phone yesterday and then when I tried to turn it on again it got stuck at the white screen that appears at first - it shows the HTC logo and the information about the software in red letters. I waited for a few minutes but nothing happened, then I reset it from the button under the back cover and still the same thing happened - it stuck at the same point. Any ideas how to fix it? Thanks so much in advance!
Sounds strange, i would try to do a hard reset, but you´ll lose all your data on the device if you do this!
Any other ideas?

To hard reset your phone which means to delete ALL personal data and settings and have the phone in factory default conditions as if you turned on the phone for the first time after purchasing, press the following buttons:
1. With the device turned off, press and hold the VOLUME UP and VOLUME DOWN buttons, then briefly press the POWER button.
2. Continue pressing the VOLUME UP and VOLUME DOWN buttons until you see this message on the screen:
"This operation will delete all your personal data, and reset all settings to the manufacturer default settings. Press VolUp to restore manufacturer defaults, or press other keys to cancel."
3. Release the VOLUME UP and VOLUME DOWN buttons.
4. Press the VOLUME UP button to perform the hard reset, or press any other button to cancel the reset.
You can also use Clear Storage to reset your device back to factory default settings.
1. On the Home screen, slide to the Settings tab and then tap All Settings.
2. On the System tab, tap Clear Storage.
3. Enter “1234” and then tap Yes.
If you have HSPL applied, you could be able to use MTTY method and upload new ROM.
Mtty tool recovery is nothing to mess with, it is a last resort. If you don't know what you are doing, you can easily kill your phone.
Do a hard reset, if that doesn't work, ( I anm assuming that since this is your first post, you do not have a custom rom ) find a copy of your rom and re flash it. But try severral hart resets first.
Thanks to all of you guys. The hard reset did the trick. I had my data backed up on the SD card so I will restore it from there. Thanks for the help.
hi guys,
i just god nexus from a second hand store. i want to hard reset it but it does't.
it is stuck in the screen where the little green guy with the triangle with an exclamation mark next to it. please help.
is there a way to load the factory rom manually?
(i know how to jailbrake and downgrade an iphone so this should not be so hard)
Hold volume down and press on once you see menu with recovery
press volume again and you will see option for clear storage - thats what you want
that is what i have done already. but why is the mobile preventing me from hard reset ?
I have been hanging around the XDA forums (as well as every other forum I could think of) and have been unable to solve my re-set problem.
I got my Nexus S about a week ago and decided to unlock it. That went well, no problem. Then I decided to root using Superboot - that did not go well. Now my phone is unresponsive, just sits on the Google name with an unlocked padlock on a black screen. I can get into fastboot mode by using the volume up and power button if I do this right after replacing the battery. I cannot seem to go anywhere else. Once I got into a menu that would let me install from sd card, but none of the options would install. I followed the following directions to see if I could do a hard reset:
Hard reset Nexus S using hardware buttons
This option is recommended if you are unable to access the options via the Android OS.
1. Turn the phone off by pressing and holding the Power button for about 2 seconds, the tapping Power off. Alternately, you can pull the and replace the battery.
2. Press and hold the Volume Down button while pressing and releasing the Power button.
3. Continue to hold the Volume Down button until you see a menu appear.
4. Now tap the Volume Down button to scroll down to the Clear Storage option.
5. Press the Power button to select Clear storage.
6. Press Volume Up to select Yes.
After a few minutes the hard reset process will be completed and you can reboot your phone to factory default settings.
I never get to the clear storage option, although I have tried data/factory reset and wipe cache. I can get to the android with the triangle and exclamation point but that will just sit for ever, and removing the battery at that point and then rebooting does not work. It just takes me back to the Google and the unlocked padlock. FWIW - my phone updated right before I unlocked it. I don't think it is bricked, but I sure can't get passed the Google name or the Triangle/android.
Thanks for any help.

I've the same problem now - did you ever resolve yours?
Here is how
Power off by removing battery
Hold vol up not down and power,
release power and you get Fastboot mode
vol down to recovery and click power
You get the screen with Android + triangle
Click up and Power again for few seconds
you will get the 'Android Sys recovery'
However if you have my problem 'error in loading the built in SDcard memory this wont help.
The only way i managed to get it to work some times although not now, is to reboot the mobile while it is connected to a PC, and load the PC at the same time.
However this time i am stuck at Google screen

Hi
Is there any way to remove a screen lock om this phone?
My son wishes to make one, but cant remember the code
Do i have to drop the phone into the garbage?
No good phone after all.
Hope some one can help me, or my son, with this.

You can factory reset the phone. I'm not sure, but I think if you keep guessing wrong, you'll get an option of logging in to the Google account associated with the phone, and.... well, actually, I don't know what happens then, since I've never done it or seen it.

Have to ask my son, if he has got that message about resetting.
Thanks
Gaasen
He hasent got that option.
Other options, to unlock ?
Gaasen
Try this:
Hardware key Reset:
1. Press the Power button to turn off the unit.
2. Press and hold down the Volume Down button located on the side of the device, then press the Power button and release it.
3. The phone should start with a menu present a list of options.
4. Use the Volume Down button and navigate to the Clear Storage option.
5. Then press on the Power button.
6. Select Yes to confirm your choice of selection.
Your Samsung Galaxy Xtreme S5690 will now reset back to factory default settings and all your data will be erased.
Hmmm...
The phone just start up, and wants the code
No list as you told.
Any other things to try out?
Gaasen
Make sure you hold down the Volume down button long enough. If still nothing, try other key combinations to get boot into factory recovery.
Cant get the "meny" to reset the phone.
If i push and holds the voloume down, press power for 2 sec, release power and still holding the voloume down, the phone loads until the screen lock appears.
I also tryed the other buttons, but just load until screen lock.
Is there any other way to reset the phone, with USB or so?

I have a infinity 700, and my son did the pattern attempts and locked it. I have been unable to use my google account to unlock it (maybe due to i'm traveling and not on my saved wi-fi)
I have tried a soft rest and hard reset. Both only reboot and go to the username/password screen.
The functions that I have tried, power and volume down or up, I get a vibration after 5-10 sec and then standard boot.
Reset button on side both while holding the power buttons and volume buttons....no success.

Wow, so you can't even wipe data/factory reset? Don't hold down the power button too long when trying to access the recovery, for it will initiate a reboot then, ; ) Do you have WiFi access *somewhere*?

Yes I went somewhere that had open WiFi, however I'm guessing it won't connect because I have never registered on it before.
If you have a custom recovery or adb enabled, you could try this:

If you have a USB to ethernet adapter (or know somebody who's got one) you could use it with the dock (if you have one) and connect to reset it.
I see a lot of you saying you've rebooted your watch. Can someone please tell me how that's done. Cuz i'm not seeing where that's possible.
I can't get any apps to install because i'm getting the gear2 not connected message. I've rebooted the phone but that didn't fix the problem.
THANK YOU.
ALSO, how do i check for and download the latest rom for the s2? If there's an update.
Press and hold the bottom right button
Assuming you wore the watch on your left hand, there are two buttons on the right side - towards the fingers of your left hand.
Press and hold the button on the bottom, and it will show you a menu to power off.
Repeat to start again.

From Tmobile support :
A master reset restores the original factory settings and may delete your personal data on the internal storage, such as downloads, ringtones, images, apps, contacts, and Visual Voicemail.
If the device menus are frozen or unresponsive, you can master reset using hardware keys. To perform a master reset, follow these steps:
Make sure that the Gear is powered off.
Press and hold the Power key until you see Galaxy Gear rebooting.
Release the Power key and then repeatedly press the Power key until you see the Reboot Select Mode screen.
Press the Power key to highlight the recovery option.
Long press the Power key (5-8 sec.) to select it. The device will reset and return to the factory initialization screen.
You can also directly reboot by simply holding the power/home button a bit longer -- about 10 seconds.
Press and hold, and when you see the "power menu" with the Power Off option, just keep holding the button until it appears to power off / go blank. Then, let go of the button. It will shortly display, "Rebooting...", and reboot.
Now, for those compsci folk out there, I don't know if this will cause any problems with caches/etc., leaving behind corrupt file system data structures or corrupting actual data, because it's not a proper shutdown of the linux kernel on the watch.
Yet, it is much simpler than the shutdown/restart method, and easier on the button (one press vs. two).
I'm not too worried, though, for a whole bunch of reasons about how linux is implemented on small and embedded devices like this with NV storage.
