I have always entered bootloader by holding power + volume down + camera button. Didn't realize there was another way!
For GB recovery its a little different. To get into stock recovery power on with power+home button, then when you are at the Exclamation point hold both volume buttons. From there select wipe data factory reset, then reboot device and see if that helps. If not then you may have to sbf.
Try powering off and pressing home and power and then search when android image shows and do factory reset.. sounds like you didn't wipe data before installing... there has been issues without doing a wipe.
Did you activate it? SBF'ing basically restores it to how it is when you open it out of the box. You have to activate it via the *611 or w/e it is. If you have the triangle where your reception should be then it isn't activated. And what do you mean ask for your name or phone number? When mine rebooted I had to activate it then add my gmail account then it asked if I wanted to add any other accounts.
