Anybody knows if something's up with the Unlock Device Tool? I get "Unknown errors..." after I click on the last confirm button. Has worked before.

    Which firmware version are you trying on?

    If you are trying on the last 119, it is possible that the tool is not yet adapted for this version.

  • When I look at my build number, that ends with 194-0. Not sure we are talking about the same thing

  • Yes, we are. So you have the latest version of Android 9.

    Android 9:









    Android 10:






  • Thanks for the clarification.

    Any info that the Unlock Device Tool wouldn't work with WW_16.1220.1909.194_0?

  • Have you ever unlocked the bootloader and do you have the experience of phone rooting?

    I don't want to bother, but why do you really need it?

  • Yes. As I said I used this tool before on this same phone. But a while after that the phone crashed because faulty motherboard. Now after Asus replaced the motherboard this tool no longer works.

    Is it working for everybody else?

  • Hi, it has been verified as working from our internal test.

    But suspect it can be a database mismatch causing it to not work, I've sent you a PM asking for your device details - we will use them to check back.

    Did they replace it under warranty without any problems?

  • Hello,

    Would there be no problems upgrading from

    WW_16.1220.1908.189_0 (stock version) to 16.1220.1909.194 (FOTA update i received)

    I have read that a certain version upgrade bricked some phones. I'm from the Philippines but my phone is from Taiwan. The phone is yet to be released here so I doubt if i can have my phone fixed here should it encounter any problem. Thanks in advance!

  • I have read that a certain version upgrade bricked some phones.

    That's not true, it's not that any version is causing problems. If you have a defective motherboard, any stress on the motherboard can cause it to fail, of course performing a firmware update is stress, the Antutu test is stress, playing challenging games is stress.

    If all this is ever done and the phone is OK, then there is a high probability that your motherboard will not suffer from this issue.
