CyanogenMod 10.1 bootloop fix

Update (2013-07-22): The file location has been updated. You can now download it from here

After updating my Samsung Galaxy S2 (SGSII, GT-I9100) to the latest CyanogenMod 10.1 nightly (20130228), I got stuck in a boot loop where it would constantly show the CyanogenMod boot logo spinning!

After some searching, I came across this post in the nightlies forum of xda developers.

So, without further ado – let’s get to fixing this bootloop!

First up, you need to have adb available:

Next, download the file as linked to from the forum thread: – 1.36 MB

Boot your device into recovery mode. For the SGSII, you do this by pressing and holding + + until the “Samsung Galaxy S II” boot screen appears.

Once in the Recovery Menu, you need to mount the /system partition:

  • Use to go to “mounts and storage”
  • Press to select
  • Use to go to “mount /system”
  • Press to select

Now, on your PC, you need to send the file to the device using your newly setup ADB:

  • Plug the device in via USB
  • Check he device is detected by running adb devices which should say something like:
    List of devices attached
    0123456789ABCDEF recovery
  • Send the file to your device:
    adb push ~/path/to/ /system/lib

Finally, you need to reboot your device:

  • Use to go to “+++++Go Back+++++”
  • Press to select
  • With “reboot system now” selected, Press to reboot

The CyanogentMod 10.1 bootloop should now be fixed 🙂

    Dear Jess,

    I have the same problem with my Xperia P installing CyanogenMod 10.1 . I tried to follow your protocol but the file needed is no longer available. Could you reupload it anywhere or do you have any other link where to find?!

    Thanks a lot in advance

    I followed your instructions. As soon as I press to reboot the typically “Samsung Galaxy SII” bootlogo is shown, but when the Cyanogenmod rotating logo should appear I get a black screen instead. It is like logo was just replace by a white picture.

    I followed the procedure the best I could. I wasn’t exactly sure what I needed to do for drivers/and rules but adb had seen my phone and pushing the file seemed to work. Now when I reboot my phone I just get a white screen. Any suggestions?
