The only way to get back into your phone is if you Hard Reset your phone.

WARNING
If you Hard Reset your phone, you will lose all your data, contacts, photos, videos, documents, text messages, phone call logs, etc.

After resetting the device, it will be as if you just taken it out of the box. Nothing will be on the phone and you will have to re enter all your contacts, settings, applications, etc again.

Acer P3250 will not acccept password

Hello
Your projector is in security lock Enabled condition. If you have forgot the pascode . You can change the password by
Use the Menu'UP'/'Down' '<'/'>' buttons to enter the four digit pascode. The default password is "ENTER,ENTER,ENTER, ENTER". After this is entered, you can put in a new pasword. Therefore when you use this function for the first time, pleas input "ENTER" four times.
To cancel the security lock, press the Menu key, then turn OFF the "Security Lock" setting on the INSTALL SETTING menu.
If you call the customer service center because you have forgotten the password, you will need to be able to veryfy the projectors' serial number and your identity. The process may differ in other countries/regions. Once your identity has been confirmed, they will provide you a password. OK.

The projector is automatically detected by laptop and then included in the secondary graphics or display as a second display component. This means that for the projector to display, you need to control it from the laptop's graphics options, i.e.
>Connect projector to laptop
> Right click on desktop and choose Graphic options.
> Choose desired option say Notebook + Display or Display alone..whichever you prefer.
It should be displaying now. Did it? Vote to let me know.

Read some Acer manual and it says:

Administrator Password

The "Administrator Password" can be used in both the "Enter
Administrator Password" and "Enter Password" dialog boxes.
• Press "Play" to change the "Administrator Password".

If you forgot your administrator password, do the following to
retrieve the administrator password:
• An unique 6-digit "Universal Password" which is printed on
the Security Card (please check accessory in the box). This
unique password is the number which will be accepted by
projector anytime no matter what the Administrator
Password is.
• If losing this security card and number, please contact with an
Acer service center.
