    I got the update ota… i tried to install it… it reboots and enters recovery… i go to install… however i can’t find the zip file to install…
    PS: i have rooted my phone…

    • Junaid Akbani

      Better to download full ota then use stock recovery and follow my procedure…ota will be stored in temporary files on internal sd.


      When you receive recovery option you choose apply update then choose internal storage then go to android folder , go to data , then go to , com.cyng.fota ,then select cache
      After that you see cm signs cm select it and install

  • ajit

    cant i update this manually ?? with 128 mb of update

  • Saurabh Suman

    I have already flashed the 650 mb cm12 zip file for s1k0 update. I have the 122mb update zip file as well. Do I need to update it or is it already included in the current OTA.
    Because, when I’m trying to update the 122mb, it fails in recovery mode after a minute.

    • It may be because you are rooted! Make sure that your not a root users and if your rooted then unroot your device and try to update it
