  1. I have a Zenfon 8 mobile phone
    I tried this new e/OS, it was good, but somehow the bootloader got locked! Now I would have to unlock because I only see the green start and the other menu items! in adb I only have one connection in fastboot!
    But I would really like to switch back to the original Asus, does that even work?
    with best regards from Austria!
