SOURCE: samsung galaxy android unlock..cannot unlock my

Hi, I have a couple of idea for you to try.
1) Log in to your google account on your pc, the same account you registered for your phone

2) After logging in look at the top right corner of your inbox/email page, it would say your google username. Like say if you name is John, and you have a google id thats registered to your galaxy s as , john123@gmail.com. Now this google id on the top right corner of the page would be displayed as john123@googlemail.com

3) Type in the google id, thats visible on the right hand top corner of your page (like john123@googlemail.com) into your galaxy s handset locked page, and type in the password.

TADA AND YOUR ON TO THE NEW SCREEN TELLING YOU TO PUT IN ANOTHER PATTERN.

or theres this one:
Take out the battery, the sim card, and the SD card leave the phone for 2 to 3 hours like that.. Put everything back in and boot up the phone.. This should work.
You could try this instead of waiting 3 hours, just remove battery and press power on switch for 20 seconds but this may not work.

or if you've tried everything, the only other way would be to take it to a Samsung mobile phone shop.
or do a factory reset:
THIS WILL ERASE ALL YOUR DATA THOUGH
Go into recovery mode - vol up & home & power. Once in the menu, select factory reset.It may take you a couple of attempts to get to the recovery mode but it does work, just keep trying.

Regards
Mike

SOURCE: Need to 'hard reset' my Samsung Galaxy Europa

I attempted the above in order to hard reset my Europa i5500. However, it didn't work, and instead just went back to the "enter address/password" screen. I've attempted to connect to Kies, but to no avail, Kies doesn't register that the product is plugged in. I can get the phone onto download mode and emergency download mode, however neither are helping me much. Any suggestions?

How to take screenshot with Panttech Sky Vega Lte


Try to push the power button and the home button at the same time! (not actually holding it, just try to do it rather quickly) If you are running IceCreamSandwich it should work (my case).

Hope it helps mate!
