The following shows how to disable the power gobbling but useless phone apk's on the scroll (mine's the Capacitative one running Android 2.3.1) without rooting it. It relies on the fact that access through the USB debugging interface has root privileges from the start without relying on exploits - as such I'm guessing that this won't invalidate your warranty (no liability accepted if it does!)? This amalgamates several snippets from other posts on here - my thanks to those giants upon whose shoulders I stand!
On Windows 7 (other, much better operating systems whose names end in an x are also available
):1) Download and install the SDK from http://developer.android.com/sdk/index.html.
2) In SDK Manager, Install the USB drivers from Available packages/Third party Add-ons/Google Inc.
3) On the PC, edit the android_winusb.inf file in Program Files/Android/android-sdk/extras/google/usb_driver and add:
- Code: Select all
; Scroll - recovery
%SingleAdbInterface% = USB_Install, USB\VID_18D1&PID_DEED
%CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_DEED&MI_01
;
; Scroll - bootloader (fastboot)
%SingleBootLoaderInterface% = USB_Install, USB\VID_18D1&PID_D00D
;
after [Google.NTx86] and again after [Google.NTamd64] (yes, I know only one of these is necessary depending on your Windows architecture - I'm just covering the bases here).
4) Edit the PATH environment variable to include the location of adb.exe.
5) Plug in the Scroll USB lead with USB debugging enabled on the Scroll.
6) From a Windows command prompt type
- Code: Select all
adb devices
adb shell
You should now have a # root prompt in your Windows command window
7) At the # prompt type:
- Code: Select all
mount -o rw,remount -t yaffs2 /dev/block/mtdblock2 /system
to make the system directory structure writable and then type:
- Code: Select all
mv /system/app/Phone.apk /system/app/Phone.old
8) Reboot your scroll.
9) Repeat Stages 6 & 7 above.
10) At the # prompt type:
- Code: Select all
mv /system/app/Mms.apk /system/app/Mms.old
mv /system/app/TelephonyProvider.apk /system/app/TelephonyProvider.old
ls -la /system/app/*.old
You should see something similar to:
- Code: Select all
-rw-r--r-- root root 885995 2011-04-28 15:12 Mms.old
-rw-r--r-- root root 1672701 2011-04-28 15:12 Phone.old
-rw-r--r-- root root 57880 2011-04-28 15:12 TelephonyProvider.old
Job done. Reboot your Scroll and your battery drain should now be a fraction of its former self.
Hope there aren't too many typos in the above. Please point them out where they exist.
