  2. Hi,
    Yes, of cource. different issues, i'm afraid:
    -"adb reboot boot-loader" should be "adb reboot bootloader". (minor issue but nevertheless....)
    When I've made all three "adb steps" for the ZE551ML Zenphone version and then rebooted the phone and copied the WW SKU img file to the internal memory root.:
    1) the phone didn't recognize the img file and did not start to update the system. Nothing happened.
    2) in the bootloader menu i can read version Z008 (instead of (Z00A) for ZE551ML. i tryed to load the files for ZE550ML and then i got Z00A version but still no system update using ZE551ML WW img file..
    3) when trying to enter recovery mode (both with adb software and with pow.on+vol.up from boot loader menue) the phone starts to update the system before it enters recovery menu, but after 1 sec i see a dead android and the message "fel!" (=failure! in Swedish). recovery menu is impossible to enter since the phone gets stuck with the dead android. a 10 sec push on power button reboots the phone.

    Before I made these trials I updated the phone with the latest CN version .For your information the phone worked from the begining with google applications such as play etc even if it was a CN SKU, after the update to the latest CN SKU all Google apps where gone and replaced with some Chines apps that you don't want.. according to ASUS support t e phone software must have been manipulated by a third party since no CN version have Google apps working with original SW. Soo maybe this is the reason why your instruction does not work with my phone. The phone is not rooted.

    Hope thsi helps! Any ideas?

      I did manage to copy the file than I removed but the update did not happen.
      And I have found that the Icons of the interface became reduced too making it more difficult.

    5. I have copied the firmware to the phone and removed the cable,as you have instructed in point no 14.
      Isn't this what you mean to manually install.
      If not, please can you explain more.
