I am not able to flash my Nexus 4 with Cyanogenmod 11 anymore. The installation does not successfully finish, which is probably why it gets stuck in a boot loop after restarting the phone.

During the initial installation by sideloading the Cyanogenmod 11 zip, the process stops at the step Installing update..

It never says update finished. So I just restarted the phone manually afterwards. But it does not boot Cyanogenmod successfully.

The phone either...

  • ...gets stuck at the Cyanogenmod boot splash indefinetely
  • ...gets stuck at the window Android is upgrading.. / Starting apps.

I have formatted the following partitions beforehand to perform a clean install: /system, /cache, /data, /persist, /firmware

    When it gets stuck at boot splash, does the cyanogenmod logo appears, so is just blank? – Anoop K P Dec 13 '13 at 8:29

    @AnoopKP The cyanogenmod logo appears 100% working. The blue arrow keeps spinning indefinitely. – king_julien Dec 13 '13 at 9:08
  • How did you did you flash CM? Did you use CWM? If yes, what version? – geffchang Dec 13 '13 at 9:28
  • Did you verify the MD5 sum of the ROM first? It could be a corrupted / incomplete zip file. What recovery are you using? I would do a full wipe of all partitions again, redownload the firmware and try it again. Also I would get another ROM to try (even if you don't intend to use it). Can you restore a nandroid even? Also, ensure you are flashing the correct ROM for your version and that you are flashing the correct gapps! (I've been here a few times before!) – RossC Dec 13 '13 at 13:02
  • @geffchang I flashed CM by manually by entering recovery mode, wiping partitions and sideloading the installer zip. – king_julien Dec 13 '13 at 15:12

I had suspected that formatting additional partitions like /firmware and /persist might be somehow related my boot loop - but I have no educated confirmation of this! Any CM aftermarket firmware that I tried would get stuck at the boot though.

The following solved my problem:

  1. Install the (latest) Google Stock Android - this is just as easy as installing Cyanogenmod
  2. Install ClockworkMod Recovery
  3. Install Cyanogenmod Rom
