  • Hi yusufarifin532

    Thank you for providing me the info. After investigating by the tech team, they found out that your device had unlocked once in February. Did you perform the unlock movement before or did you purchased the device from second-hand resource? Have you change the motherboard before?

  • In my case, I performed the unlock when I first purchased the phone in 2018, but it went into an unbootable (soft brick) state, so I had to use the firehose to restore a factory image. I was able to unlock again at that point; but recently, I wanted to update the software version and it wouldn't let me, so I ran the firehose process again, updated to the latest software, and tried unlocking to no avail.

    hi agent,

    I am also having the same problem. But as you said, i unlocked it long back. and never relocked it.but recently i ve changed the mother board from ASUS Authoraised service centre. since then i am getting the same error. My model is ASus 6z,bought in july2019 india. I ve titanium backup of my old apps and data. so i nee desperately need root.

    pls help

    So what I understood is, when u've already unlocked once it's registered in Asus Database. And when they changed motherboard it came with locked bootloaders. But now when I try to unlock it again,it's checking in the database n found that the device is already unlocked n hence its giving the error.

    But what is the solution to this problem?are we struck up with locked bootloaders for ever? Or is there someone who can help us? I think the programmer has not seen this condition coming. I.e out of repair at service centre.. getting the unlocked to locked state.

    One final doubt,if the service centre can lock the unlocked bootloaders,

    can they unlock the locked bootloaders? Pls tell me if so I LL get it done there.

    Else I don't have any option other than to sell this n buy a phone which is rootable. Becoz Root is must for me as I ve huge data n apps backed up with Titanium Backup.

    Pls help




  • I'm not sure this solution will work.


    Try downgrading to older firmware like 2018 or 2019 version of firmware and then use that app to unlock bootloader.

  • yes i unlock february but . my phone get brick and get flash raw file WW_ZE620KL_15.0610.1801.42_M3.5.11.6-ASUS_1.1.7_Phone-user.raw 

    my phone get normal again but bootloader get relocked again :)

    change motherboard nope 😶

    Hello,

    I bought this Asus phone this morning, but Unlock App doesn't work.

    Please tell us some basic information before asking for help:

    1. Model Name: Zenfone Max Pro M2 ASUS_X01BDA (ZB631KL-4D103TW)
    2. Firmware Version: OPM1.WW_Phone-15.2016.1902.192-20190226 (this is build number...where is the firmware version?)
    3. Rooted or not: NOT
    4. Frequency of Occurrence: Always
    5. APP Name & APP Version (If your issue relates to the app): Unlock Device App version 9.1.0.7_180912

    Error message in the Unlock Device App:

    "An unknown error occurs, which may be a network connection issue, please wait and try again."


    It seems many people are having this problem :/

  • Yes, many people are having this problem; and judging by the fact that your device is brand new, it's not an issue with our devices having been unlocked before. It is probably an issue with the unlock server again like it was back in 2012.

    See this thread on XDA-Developers: https://www.xda-developers.com/asus-unlocker-tool-broken-asus-claims-rma-is-the-answer/

    Hopefully, whoever controls it can fix this issue again.

  • Hi elias888

    Thank you for your asking. Based on your device is brand new, like AgentTechnoman said, your issue should be different from theirs.

    Yet because your model is ZB631KL, please refer to the link below as Max Pro Series, and open a new thread there

    https://zentalk.asus.com/en/categories/ww_zenfone-max-pro-series

    Please provide me the screenshot of your error message and your issue in your new thread. Then check on your inbox and PM me your SN. I will forward the information to the relevant department.
