Is there a pie firmware for the Zenfone 6 in the US I need to downgrade because I unlocked with Android Q on the phone and it's messed up my fingerprint sensor it doesn't work at all please help thank you.


  • The download is available here. https://www.asus.com/Phone/ZenFone-6-ZS630KL/HelpDesk_BIOS/

    In the notes, it says "ASUS ZenFone 6 ZS630KL Software downgrade from WW-17.1810.1910.63 (Android Q) to target Image Version: WW-16.1220.1909.194 (Android P)"

    Based on that, I am unsure if your current version of Android 10 can be downgraded, but it shouldn't hurt to try.

  • Yes but I'm on WW-17.1810.2001.129

    Currently and not sure it will have all of the US bands I need . I want confirmation from someone at Asus before I try anyting like that!

  • I haven't tried to downgrade back to 9 with multiple versions of Android 10, that's why I noted it may not be possible with the most current version.

    You won't lose access to any of the bands, that is a hardware function that doesn't fluctuate with firmware.

    If the only thing you are worried about is the lack of a fingerprint sensor and are otherwise satisfied with Android 10, then I recommend backing up all of your data and performing a factory reset. The upgrade from Android 9 to 10 messed with the fingerprint features for many users, but was easily resolved with a factory reset.

  • Any version of Android 10 is downgraded to Android 9 with the same firmware, even for future Android 10.

    So if this is true why does it say this?

    "Version Android Q downgrade to Android P

    ASUS ZenFone 6 ZS630KL Software downgrade from WW-17.1810.1910.63 (Android Q) to target Image Version: WW-16.1220.1909.194 (Android P) by using MicroSD card for WW SKU only* Please follow step 6 and ensure to backup data before downgrade.

    Steps of Update:

    1. Prepare a MicroSD card.

    2. Check software version of your device**

    3. Only apply to same SKU update, Example: WW->WW, CN->CN, TW->TW, ID->ID.

    4. Software update cannot transfer the software SKU.

    5. Wrong SKU may cause update failure, please update the same SKU version only.

    6. How to manual update firmware please refer to"

    This says downgrade from WW-17.1810.1910.63 To version WW-16.1220.1909.194. don't I need to be on firmware version WW-17.1810.1910.63 for this to work for my phone ?

  • It wasn't the update that did this. It was unlocking the bootloader while on Android Q . Unlocking while on Android Pie does not have this issue . So I need to get back to pie without bricking my phone lol

  • So it won't break my phone to use the downgrade zip on Asus website? Is that what you mean

  • Downgrading will clear the data in the phone. Please make sure the data is copied first.

  • Downgraded firmware can be used in all versions of Android 10 firmware down to Android 9.194, not limited to only .63
