So if I want my GPS to work (or possibly improve) my steps should be:
d/l DI18
Lock my GPS
Make a nandroid and wipe data/cache 3 times and flash the stock rom and reboot
reboot, go back into clockwork and flash the update.zip for 2.2.1 - which is DK28 update
then install TulyEpic via:
1) Put the zip file of the ROM on your SD card
2) Boot into Clockwork, go to "backup and restore" and then "Restore" (now you have a backup of your phone just in case).
3) Go to and execute "wipe data/factory reset". Then go to and execute "wipe cache partition".
4) Go to "install zip from SD card" then to "choose zip from SD card", find the zip of your ROM and select and install it.
5) Reboot and done!
Hopefully my GPS will lock.
