Cisco 7940/7960 “Configuring IP” problem (FreePBX/Asterisk 1.4)

I was recently programming our new ip phones, and was upset to find that they couldn’t get past the “Configuring IP” part of the boot-up phase. Googling only turns up suggestions to do a factory reset. So I followed the instructions, but they didn’t help. Here’s how you do it anyway:
1.) Power the phone off
2.) Power the phone on, then immediately press and hold the ‘#’ button.
3.) The boot up light sequence will commence, after which the screen will prompt ‘Reset key sequence detected.’ You can release the ‘#’ key now
4.) You now have 60 seconds to input this sequence: ‘123456789*0#’ (the whole keypad, left to right, top to bottom)
5.) Choose whether to keep the network config or not (since it is a reset after all, I’d recommend not keeping it)
6.) The phone should then reboot.
Okay, from a bit of experimenting, I was finally able to get past that annoying ‘Configuring IP’ part, turns out in our case the phone didn’t detect our tftpboot server. Here’s what I did:
1.) Press the Settings button.
2.) Go to Network Configuration.
3.) Scroll down to Alternate TFTP (which by default should say: NO)
4.) Unlock it (press **#), then change it to YES.
5.) Scroll back up to TFTP Server 1, Unlock it (using code above) and enter in your tftpboot servers’ IP.
6.) Push ‘Save’. The phone should reboot and now continue on
