Edit your message and remove your device DeviceSerialNumber and DeviceUniqueID, please.
I'm rather sure when you follow Lemonfish his tutorial everything must be OK.
Most important is that all files and maps or folders are in the same root of your device.
If you use a SD card clear the internal memory.
Are you sure about the bootloader 1.00012 ? In that case it's not possible to upgrade, only SD cards up to 2GB is possible for you.
The next file, folders and maps must be on your SD card.
Any map you wish which will fit the SD card and which have a meta code available.
Now start FastActivate with the options #1 #2 and #3, #1 to update the meta.txt file, #3 just to be sure your Navcore is patched too.
Look if you see any errors on the screen, when not found, go into the map folder to see if there is a .dct file
When there's no .dct file your maps is not patched the rght way and won't work.
