Can you help me ?

History :

Wanted to update to MM

- unrooted

- try recovery mode and install from asus support new firmware with adb, problem was that i had a custom recovery, i think this is what failed and i had black screen after the update.

- followed your tutorial

- stuck at asus boot logo after having the error i pasted above.

Edit : Seems the archive is corrupted, 7zip throw following error when i extract : Data error : system.img

Gonna try raw file from there : http://xdaforums.com/zenfone2/general/guide-fix-bricked-ze550ml-ze551ml-usb-t3405840

May be i had a problem while downloading the previous one, but i prefer to test another one.
