Since you're rooted within CM, its a matter of doing the following, provided you have read the following:
The Jellybean leaked apks are signed with the signature key used to generate the signed leaked ROM of JB, however, it may clash with CM's own signature key which is, and I'll guarantee, different, so may not work at all!
You are on your own from there onwards.
- remounting the
/system rewriteable as in
adb remount to make it writeable
- replace the apk's concerned within
/system/app by adb pushing the appropriate apks taken from JB, as in
adb push name_of_jb_apk.apk /system/app (Repeat for each apk concerned) - this will overwrite the apk's already residing in
- remount the
/system as read-only as in
Reboot, and go into clockworkmod recovery and clear the data/cache, the reason being is to remove the old cached data that was in use by the old apk's, and thus, minimize the chances of force closes within the relevant apks in question.
I will list the actual filenames for the apk's concerned:
- Sms, the filename is
- Contacts, there's two apks involved,
- Dialler, name is
Phone.apk, now, beware, this may have a dependency on
Whilst I have mentioned the actual apk's, I am therefore disclaiming any responsibility for anything that may happen on your handset as a result of replacing system apps.
