Why is it not accepting your gmail account? Dont you remember which Gmail account you used to start using the Android phone? As far as I know, there is no "reset" to this. You will have to reinstall the OS. Connect your phone to the PC and look for update of Android version. If there is no update, you will have to "ROOT" your android phone. There are many many tutorials online on how to do that. But it is risky and if you mess anything up it might BRICK YOUR PHONE. Meaning, your phone will become nothing more than a paper weight.

Best thing is to remember the gmail account that was used and follow the steps. I have done this and it was pretty straight forward.

I found the following on another website. I don't know if it's true.
One thing unique about Android phones is their pattern unlocking system. However, after a number of unsuccessful tries, it will lock you out permanently. This happened to my brother, and it wouldn't accept his gmail username and password (the only other login method). He was looking at a reset and loss of all his data not stored in his Google account. Luckily, he found a work around. If you enter your gmail account name, and use "null" as the password, it will enable the pattern unlock again. This may give you a chance to try different patterns until you find the one you set.

Hi,

Step to setup an email account on Samsung wave:
1. Press Menu
2. Select My Accounts
3. Choose the type of email account you want to configure . For Gmail, select "Google "
4. Enter your e - mail address and password and click " Next "
5. A new window pops up. Select apply without making any changes.

You will need to configure your Gmail for IMAP or POP pushing first before authorization is given to your Wave to accept the pushed mail.

Login to Gmail -> Setting (top right hand corner) -> Forwarding and POP/IMAP -> Check Enable POP for all mail arriving from now on and check Enable IMAP.

You are done with configuring GMail side.

Now, add your google mail account under "My Account".

Enter your email (username will be filled up automatically), then your password.

Next, when you hit the next screen, DO NOT CONFIGURE ANYTHING. Simply "Set".

Make sure u have POP and SMTP enabled in your mail account before you try this and yahoo users make sure u enter your mail address as that of your domain
example : [email protected]
where xx can be something like uk or us or in etc
