SOURCE: i have macbook osx an im locked out , i have no info

By not being more specific, when you note that you are locked out of your Macbook, I would have to presume you are referring to your User Administrator account or you have a FileVault password which is prompted for, upon booting up and you have forgotten that password.

Not sure which could be the case, so I will 1st provide you steps for resetting your Administrator password with your Mac OS X installation disc and 2nd, provide you, a key Apple support link, for fixing the forgotten FileVault password (just in case this is the culprit, which is locking you out of your Macbook).

• Place your installation Disk (Tiger or Leopard I presume) into your drive and
allow it to load.
• Restart your Mac
• As soon as you hear the Apple Chime, press the "C" key on your keyboard
and hold it.
• You will see a White Screen, Grey Apple first, do not release the C key until you
see a Spinning gear.
• Once you see that Spinning gear, release your C key and allow the disc to
continue loading

(Works for both Mac OS X 10.4 (Tiger) and Mac OS X 10.5 (Leopard))

• When the booting to the Mac OS X disc is completed, you will now be in the
Installer environment
• Enter to next page, look up on upper left corner you should see "Installer" near
the Apple menu.

• Two spaces over you should see Utilities. Click Utilities>Reset Password.
• Select your user name from the drop down list and reset your password.
• When you are done, simply exit the Reset Password and Installer and reboot.

• At the Login window, enter your new password and you should be back into your home User Administrator account.

I have forgotten the password of my alcatel lucent ip touch phone, how can i unlock it again


1. Enter the last four digits of your phone number on your cell phone PIN screen.

2. Enter 9999, and if that doesn't work try 1111, and if that doesn't work try other four-digit numbers you may have entered.

3. Shut off your cell phone, take off the back of your phone and pull out the battery. Record the IMEI number which is under the battery. Re-insert the battery and power on the phone. Enter the last four digits of the IMEI number on the PIN entry screen.

4. Call your service provider and request the unlock PIN if none of your attempts so far have worked. You will have to prove you are a customer by stating your cell phone number, address and Social Security number.

5. Turn off your phone. Hold the keys "3," "*" and "Call" and switch the phone on. Hold the three buttons down until the word "Formatting..." appears on the screen. This should reset the phone lock code.

6. Go the links in the Resources section and have your IMEI number ready. These websites will ask for your phone model and IMEI number and then charge you a set fee for the unlock code.

Sony ericson xperia i10 I want to know how to unlock my phone? when i inset the simcard it asking for pin no, and i don't know with with provider my phone is lock?

You need to get a PUK code from your service provider. Since it's the sim card that locks not the phone they are the only ones who can provide it. Enter the wrong pin code 3 tiimes and the phone will lock. Then enter the PUK code and this will unlock it. You'll then be asked to enter a new pin code which will become your new pin number.

Subsidy Unlock code for att lg gr500

Make sure the phone is on so that you can enter the appropriate code. The unlock code is *#865625#.
  • Entering the code

The phone needs to be on for you to enter the appropriate code. You will need to keep the SIM card in the phone so that it recognizes the phone's unlock code. Enter *#865625#. The screen will then ask you if you want to continue. Select yes.

  • Second code

You need to enter the code a second time. So basically, just repeat the first steps mentioned to enter the unlock code given above. Once the code has been entered a second time the screen should read that the 'Network Unlock is Deactivated'. The code and the unlock work for the GSM network, meaning that if you want to use the phone with a different service provider you are now able to.

  • Other unlock

Sometimes one does not want to unlock the phone for GSM network use, but because the keypad is locked. If you have locked the keypad and this is what you want to unlock try the last four digits of the phone number. This is often the default code for the number pad. If that number is unsuccessful consider what you might have personally used as a four digit pin. Most of us use the same number that belongs to our ATM or other device that requires a four digit pin.

If the code provided in the first steps is not the correct one, you may want to look for a sixteen digit code on the back of your phone. It may be on the battery or just behind the battery. It tends to look like a barcode. Sometimes companies use this code as the locking mechanism for the GSM network. Tolearn more you can see our unlock-any-lg
