Downgrade Android 13 to Android 12

Rising Star I

Model Name: ZenFone 8
Firmware Version: WW_33.0210.0210.210 (TKQ1.220807.001.33.0210.0210.210)
Rooted or not: No

I would like to downgrade my ZenFone 8 to Android 12. I downloaded the firmware from the support webpage. I put the file in internal memory (root directory). I also removed the Google account.

Unfortunately, no pop up message about the update appeared. I have restarted the phone, but the downgrade firmware is still not detected. The AppUpdateService and SystemUpdateService services are running in the background.

How can I initiate the downgrade procedure?


Hi InteRadek,

Can you please share the link of the firmware?  Thanks so much.

hello all,

Do you still have a copy the firmware for android 12, it seems that the website where you can download is no longer available.

Hi inteRadek, do you still have a copy of the firmware?  Can you share it?  I can't find it anymore from Asus' support page, thanks in advance.

Hi @Gregg , I provided the link to the firmware file hosted on in this thread 3 weeks ago and the link is active, so you can download it anytime.

Hi InteRadek, my apologies, I can't find the link in the thread you mentioned, can you share it again here please?  Thanks so much
