Help ! I've disabled superuser, but now (as I always don't manage to install SuperSU) superuser has disappeared from settings so I can't reactivate it by this way. I've reinstalled your rom, but superuser is always not visible (and I've lost root rights). How can I get superuser back ?
Thank's

Manage Apps -> clear Settings app's data.

Thank's for your quick answer !
I've made that, but it makes the developer option disappear without getting back the superuser one !

OK. Try to delete /data/data/com.android.settings/ folder and then reboot.
It should completely remove all settings data. But I'm not sure if there's any side effect or not. So remember to backup your ROM data before doing it.

Hé hé ! To do that, it seems I need root rights, that I no more have after disabling superuser...

You can run it using adb on Windows or Linux.

adb shell rm -rf /data/data/com.android.settings/
adb shell reboot

I've tried this, as my HD2 has rebooted after the second command I assume the first one (no error message) was OK, but superuser is still desactivated and unvisible in settings.

Are you trying to use the superuser that's built in to the ROM or SuperSu or Superuser .apk? If you're trying to use a version other than what's included already in cyanogenmod then you need to flash it from recovery or else you won't be able to overwrite the default binary already in /system/xbin. You can manage the included su from system settings, but there won't be any applet unless you install one of the other versions from the market and overwrite by flashing as previously mentioned. If you choose to go this route I highly recommend SuperSu as It's still being actively developed where as superuser isn't anymore.

I hope this helps.

Ciao

Maybe the permission of /system/xbin/su is incorrect.

Code: Select all

adb shell chmod 6755 /system/xbin/su
adb shell ls -l /system/xbin/su


If not, then I'm out of idea since I didn't see any logcat.

As Odysseus said, maybe to flash SuperSu is quicker for you since you cannot see Settings -> Superuser option.

flashing supersu to nativesd rom is more difficult no?
maybe put in zip file and install rom again?

You don't need to flash the whole ROM.
Download any flashable updater file, e.g., HD2_HW_video_decoding_and_encoding_for_CM-10.1_updater.zip, remove all files in the system path in the zip file and add SuperSu.apk to system/app/ path.
