After 24 hours or so of trying to gain root with a flasher i came across this alternative method.

Directions are here to gain root without a flasher: http://maemo.org/maemowiki/HowDoiBecomeRoot2

1. Install DropBear SSH Server on the 770 http://matt.ucc.asn.au/dropbear/dropbear.html
2. Connect the 770 to your wireless lan.
3. From your home computer open a terminal and type root@00.00.00.00 <the ip adress of the 770.
4. It will ask for a password put in rootme .
At this point you should have gained root access to your device. Now, for the future, unless you want to keep SSH-ing from another machine, a clever move is to add "user" to sudoers: echo "user ALL = PASSWD: /bin/su" >> /etc/sudoers
The user account on the 770 doesnt have a password by default so add one.
5. Type in passwd user then type in a password you want to use between 3 and 8 leters or numbers.
6. Now you can gain root on the 770 using xterm by entering sudo su -
7. Xterm asks for a password, enter the password you created for the user account.

All this just to change an icon sheeeeeeeesh!
Sorry I didn't give a description of my system. I'm running 2006.
