Yesterday a challenge was set on the XDA Forums to see if any users could manage to get Google Maps Navigation to work on the T-Mobile G1. The thread was opened at 8:32pm last night with an answer to the problem being provided at 3:36am this morning with full instructions how to complete the hack.
Alright… i’ve yet to be able to identify the specific lines yet… but here you go.
I was able to get navigation using the 2 build props attached.
I used SU File Browser and adb to do this. You can do it all with adb but between the 2 i was able to do things faster.
Mount system as rw
delete build.prop and build.trout.prop
(or you may modify yours to match, and skip the next step)
push the new build.prop and build.trout.prop to /system/
delete /system/app/Maps.apk
delete /system/sd/app/com.google.android.maps.apk if present
delete /system/sd/dalvik-cache/data@[email protected]@classes. dex
REBOOT you have to reboot for the phone to re-read the build props
install the new maps.apk — i did adb installif you do not get Success then you missed something. update: after all is working.. you may put your old build props back
