first, everything is done using clockworks.
heres what I had done, full format of everything, all partitions, etc. systemm was as clean as I could make it.
install froyo from link here on DF (latest one) then 125-1000 p3 kernel, then installed 1041. maps work but market shows the install error. I then installed launcher pro (NO theme, stock lp) and still market shows map error.
I then applied market fix from first post here and no change. I then fix maps using adb cmds below as they are only ones that ever worked for me.
adb kill-server
adb root
adb remount
adb shell rm /system/app/Maps.apk
exit
adb uninstall com.google.android.apps.maps
ok everything working and am on 1041 at this point.
I then applied 105 direct over this and maps issue is back. I did not fix using abd as I wanted to see if rolling back to 1041 through backup done just before 105 fixed it, and it did.
reapply 105 and same issue, so i just rolled back again to wait and see.
edit: forgot to add I can fix using adb if you think that would help narrow it down.
as always, whatever I can do to help I will try to do
edit 2: I also tried bugless beast earlier in that day and maps were broken right from the start.
I wonder if different phones have some sort of revision differences internally affecting this.
