    • You can try it on rooted phone…if not work then you have to flash full stock lollipop firmware, flash it from adb and then flash the Marshmallow file

  1. My question is, if this way is safe or has more risks then the one that is coming through OTA?

    I live in Romania, i just want to know if i have more to wait or if i can update manually, and there are no problems (like losing the original state of the device – from stock)/

    Thank you.

    • This is the official stock firmware so its completely safe…and its the same update which you will get via OTA. And you remain on stock firmware either you update via OTA or manually.

  2. The program send me “Cannot read”

    What can I do?

    • Did you execute the command correctly? and make sure you placed zip file in right place

  3. I followed all the steps correctly, but I get this error while installing the update:

    system partition has unexpected content
    error in /sideload/ (status 7)

    is there anyway I could fix this?

    • status 7 showed if you are not using completely stock firmware. Are you using custom ROM, recovery or disable any stock apps? or are you using rooted phone or unlock bootloader?

      • i disabled stock apps. will try to enable them all and try to update again, thanks.

      • update: the error still pops up, even after factory resetting.

        my phone has never been rooted and not been bootloaded since I just got it recently.

        • If you still facing the error then I suggest you to download and flash stock lollipop again and then try

    • Its already available I forgot to add it…Thanks, the post is now updated with ZE550KL link.

  4.

  5. Im stuck with version. Which one should i download is it and so on? I had difficulties updating as i am skipping my previous update so i really had a hard time on this. Any advice would be better. (Ze550kl non rooted)
