If you have any questions or suggestions related to this post, feel free to leave that in the comment section below 🙂


  1. why downloading the file goes down to 10 kilo bite per second which makes it taking more then 20 hours download is no one capable of uploading it to a torrent or some other fast server ??

  2. what about Greece? also, does anybody know when the update will be available in general? great phone, poor service and accessories cannot be found almost anywhere online…unless someone knows an e-shop….

  3. The link in the article refers to the Spain updates (the list can be found here – – worked for me in Ukraine.
    There are 3 updates – V1.0.0B11, the latest Marshmallow; V1.2.0B05 – Nougat update and the third is to revert back from Nougat to Marshmallow:
    – V1.0.0B11 –
    – V1.2.0B05 –
    – V1.0.0B11(SD rm_userdata)N rollback M –

    Official upgrade guide (also found in the zip files) also says to remove the SIM card before the update
    And you need an external micro SD card (I used 16 GB card)

    I had the V1.0.0B04 installed initially and it is necessary to update to latest Marshmallow first (V1.0.0B11):
    – unzip the downloaded
    – get the SD card, insert into Axon
    – go to settings, format the card
    – Note: it is important to format it, on the first try I got “can’t mount /sdcard/” (and “sorry you can’t sdcard upgrade” in manual mode from recovery) – formatting helped
    – put to the root of the SD card
    – open settings – update, it should show the update
    – press “update” button, the phone will reboot and install the update

    Now Install V1.2.0B05 – this is Nougat – use the – repeat the process above.
    Note: after installation the phone switched off; had to turn it on manually.
    Put back the SIM card.

    One more note regarding the second update method (manual update from recovery): it is not necessary to enable developer option and USB debugging for it, the update can be applied from the system recovery (power off and hold volume up + power to enter recovery, select “apply update from sd card”
