ohh great I just did something bad...

I think I screwed big time on my tomtom go 720 a few hours ago. Last year I did managed to install the maps and did the required stuff to get it running then I decided to refresh the maps with new once today and I thought it would be a simple download this and install it there....nope it just messed things up. Now I want to do it again from scratch and just went through the pages and I cannot seem to find the steps I did to get it working again. Can anybody point me to the right direction on what needs to be done. So basically I want to wipe clean the internal and sd card and reload everything again but my peanut brain is not working right now and I am just confused.

1. delete everything on internal except ttgo.bif
2. run http://www.tomtom.com/updates/clear_flash/clear_flash.exe on internal
3. install the right navcore for your device -> http://www.navitotal.com/viewtopic.php?f=124&t=907
4. copy latest Fastactivate on internal -> http://www.navitotal.com/viewtopic.php?f=127&t=19452
5. choose map you need and copy the map on internal (map needs to be inside a folder)
6. optional copy speedcams, voices, etc
7. run Fastactivate and choose options 1, 2, 3, 4
8. unplug device and start up
9. plug device on pc and run tomtom home for extra updates like mapshare
10. check if your voice is ok, else download a voice

Thanks! Got it working again. I just noticed that I need to repatch the navicore again and again everytime I place a new map before activating the maps. Was it always like that?
