in FE, you need to enable "root explorer" in settings, and also when in the system folder, u have to "mount" as read/write, by default it is read only, that's why it failed.
to push manually (this is funner):
-if u don't have HTC Sync installed, download & install the
drivers
-if u don't have SDK installed, download & extract
these files to a folder (ie, c:\sdktools)
-copy
SystemUI.apk to the same folder (ie, c:\sdktools)
-reboot phone into recovery
-connect phone to pc via usb cable
-open a command window to that folder (in W7, hold shift, then right click the folder, then choose open cmd window)
-in the cmd window type,
adb devices, it should look something like this:
Code:
c:\SDKtools>adb devices
List of devices attached
HT16JHX***** recovery
-now type,
adb shell mount /system
-then,
adb push SystemUI.apk /system/app
-then
adb reboot
verify u have the new icons
