As you know I bricked my nav. But on the bright side I now have time to dig into the firmware more. Don't tell my wife she is real mad about the brick.
Anyway I have looked at the links above and was already using IDA PRO and kunix ldw. But I still don't know how you guys are breaking the fw_all.bin into regions.
I have put fw_all into rgn_tools and all I get is fw_all. Sorry for being so thick but I real want to understand and play with this firmware. If I can get a handle
on how to mod the nag out then hopefully I/we will be able to do it to all versions. Just as you know a lot of people would benefit from the NT hack I know a
lot of people would like to get around the nag screen. Also I have no interest in defeating the speed lockout. If we can get around the nag there is no good/safe
use in defeating the lockout. But if I can get a handle on this firmware I would try to fix the poi search.
