Xposed Installer Help

[pops1368]

Hi guys

Apologies if this has been posted in the wrong section.

I have recently inherited a Galaxy S2 (GT-I9100) running the CyanogenMod 12.1, Android Version 5.1.1

I have spent the last two day trying to and failing miserably to install Xposed Installer V3.0 Alpha 2, I have searched Google and read through numerous forums on how to resolve this, but the more I read the more confusing it becomes. I would really appreciate any help/assistance in helping me fix the problem, so that I can run the app without any issues. When I access the app's log it states:

data/data/de.robv,android,xposed.installer/log/error.logpen failed. ENOENT (No such file or directory)

Also, when I try to run Titanium Backup 6.1.0, I get an error stating:

Sorry, I could not acquire root privileges. This application will *not* work! Please very that your ROM is rooted, and try again.
This attempt was made using the "/system/xbin/su" command.

I have gone into Developer Options and set Root Access to Apps and ADB.

As I new to Android my understanding (please correct me if I am wrong) that the CyanogenMod 12.1 was actually a ROM and therefore Titanium Backup should work. FYI SD Maid not working.

Any help on both of these issues would be most appreciate, please bear in mind I am a noob where Android and Galaxy S2 are concerned.

Thanks in advance.

The forum for the i9100 is located here, but because it's so close to the i777 we can probably help a bit.

Sounds to me like your phone isn't rooted, as none of the apps you mention will work without root privileges. Install the latest SuperSU; you should be getting access prompts if you're correctly rooted.

If you are not prompted for root access when opening apps such as Titanium Backup, you'll need to install Framaroot and use the Aragorn exploit in order to easily root your device. Let us know if either of these work for you.

Hi Steve

Thanks for the reply.

I should have mentioned that I already have Super SU installed and for certain apps it does ask me to grant access. If open Super SU it displays the following apps:

Titanium Backup
Root Explorer

Strange. In that case have you tried doing a complete wipe in recovery, then reinstalling the ROM? In your case you would boot into recovery, wipe /system and dalvik cache, then install ROM and gapps. Just make absolutely certain you're running a custom recovery before doing this, such as CWM (ClockworkMOD) or TWRP (TeamWin), or you could damage your device if you're on stock recovery. And, of course, make sure you have the ROM/gapps already on your device before wiping everything!

Because you inherited the device the best method would normally be to flash back to stock and start all over - if for nothing else it's a good learning experience. Hope this helps.

Hi Steve

Thanks for the reply and your advice/information, very informativinformativ.

I was trying to avoid a complete wipe and reinstalling the ROM again, as Android is new to me and I don't want to mess up the installation and wreck the phone, even it was free. However, I think I have no choice and will have to bite the bullet and do it.

Thanks once again.

As long as you have a custom recovery there's very little that can go wrong with a full wipe. I would suggest booting into recovery first (power button + both volume keys, then release at the Samsung logo) and make sure you're running either CWM or TWRP. While in recovery do a backup first, as a "just in case". You can always restore your device fully from a backup.

The next thing to remember is to make sure your ROM/gapps are compatible with one another. For instance, if you're installing a CM12 (Android 5.0+) ROM make sure your gapps are also 5.0+.

Best of luck!

When I attempt to go into Recovery Mode it does so, but opens a CyanogenMod screeb, it dies not show any options to backup/restore, it foes however have the complete wipe option. When I run ROM Manager I have done the following Recovery Setup, which now shows Recovery Already Installed:

ClockworkMod Recovery
TWRP

But I don't understand what I'm doing wrong, for neither option to be available in Recovery Mode?

Best option for you is to go to the i9100 forum and download a kernel for your phone that is compatible with the OS version you want to install (CM12, which is 5.1. in your case). With your device (as well as our i777), the kernel and recovery are fused together, so you cannot use ROM Manager to install a recovery to a separate partition.

Once you have an i9100 5.1 kernel downloaded on your phone you can flash it through the current recovery you have, then immediately reboot back into recovery. You'll then have the correct recovery and can proceed as normal with the ROM installation.

CWM absolutely has a backup/restore option, but it's hidden in a sub menu. My personal recommendation is to use TWRP recovery, as it's still being developed and is more robust/user friendly.

So as a general rule stay away from ROM Manager for system specific changes.
