How do I unlock my homescreen where it doesn't need a pin code?

Sorry but the only thing to do is do a hard reset. You will loose all data, it will revert back to "out of the box" Google the model number of the phone to find out how to do the hard reset or call your cell phone service provider.

try this pin....81343830...let me kno if it works

• To restore your N97 factory setting you need to Press *#7380# - then enter 12345. This is for soft reset.
• To hard reset the phone, dial *#7370# from the homescreen and enter Lock Code 12345.
• If the code does not work, maybe the code was previously replaced.
• Or you may try generating code here though this is not a guarantee that it will work : http://www.mobile-unlocker.com/unlock-your-phone/rs2wp2/

Hi,

PUK code doesn't belongs to any mobile handsets its for a Sim card which you are using.
Contact your Sim card Operator at costumer call center and ask for PUK they will Provide you easily.

try to input these codes on the homescreen of your phone:
**#2640# Displays phone security code in use

*#7328748263373738# resets security code.
Default security code is 12345

Hello, what sim network in your phones? Are you still used t-mobile sim card? Or you have change that sim card before? it seems you phones unlocked and you need HTC Touch HD2 unlock code so you can access your phones again. Try call T-mobile customer service and requested HTC unlock code for your phones, this process needs 1-2 weeks before you get that unlock code and don't forget to prepare some money to pay charge from t-mobile. If you need that code immediately you also can buy unlock code from third party sites with lower price and just need to wait a couple minutes.

i can't unlock my mobile homescreen because of too many pattern attempts so i need to sign in my google account to unlock it but i don't know my username and password what should i do?

Your phone’s four-digit unlock code is originally set to 1234 or to the last four digits of your phone number.
The six-digit security code is originally set to 000000.
Your service provider may reset these codes before you get your phone.
If your service provider didn’t change these codes, you should change them to prevent others from accessing your personal information. The unlock code must contain four digits. The security code must contain six digits.
To change a code or password:
Find it: Settings > Security > New Passwords
You can also change your SIM PIN codes or callbarring password.
Select the type of code you want to change, enter the old code when prompted, and then enter the new code.
If you forget your unlock code: At the Enter Unlock Code: prompt, try entering 1234 or the last four digits of your phone number. If that doesn’t work, contact your service provider.
If you forget other codes: If you forget your security code, SIM PIN code, PIN2 code, or call barring password, contact your service provider.

This phone is locked with one wireless provider only (Centenniel Wireless).

If you still have the SIM package, check for PUK1 or PUK2. Those are the SIM pin codes.

If you don't have a SIM package anymore, then you need to bring the phone in any local phone repair shop, because most of them has a software they use to unlock the phone.

Good luck!

I think this will help....
