I'm still having the same problem, I updated but it doesn't work, look at the screenshots.
Mi Box 3 (MDZ-16-AB) downgrade Android 9 Pie to Android 8 oreo
- Thread starter deep00007
- Start date
I'm currently not near my Mi Box but if you are sure that your are using the last firmware, try this:
1) Restart your box
2) If that doesn't work, log out of your account and sign-in again.
3) If that doesn't work, clear app data of Netflix app.
That's what Netflix suggests to try first
If all this doesn't work, you have to factory reset the box.
Settings -> Storage & reset -> Factory data reset.
I've done this, and also using the back button control + ok button on the booting screen
Hello. I've downgraded my Mibox 3 to Android 8 last year (from the first built of Android 9 I think), but today I found my device updated to the latest build of Android 9 (3934). Can I dowgrade once again using the original tutorial or do I have to to something different this time? Is there a new tutorial? Thank you!
Edit: managed to downgrade using the tutorial in post #62. Thank you all!

Aida64 results this is unfortunately a known problem with the firmware of mibox, or the 8th android and the clock frequency 2000 or the 9th android and the the clock frequency 1500. so if you just update the firmware from the 8th android to the 9th, you get a 25% performance decrease.
I can't enter in security mode on Pie 9 build pi.3934
Does anyone have the same problem
Edit: Got it, clicking back button twice.

7This method will not work if the device is updated to 3617 version. To downgrade from Android 9 3617 to Android 8, first you need to half brick your Mi Box.
1. To do that you need to install Android 8 2562 update through recovery. Download the android 8 2562 update from following link (https://disk.yandex.com/d/RnN2hz_IUEMOSg?w=1) and copy the update.zip and xiaomi_update files to root of your FAT32 USB drive.
2. Turn off the Mi Box, connect the USB drive to Mi Box and power on the box using BACK+OK buttons and don't release it until you see installing update screen with big circle.
3. It will try install the update and will restart the device. After restart it will be half bricked and will be stuck at Mi screensaver page.
4. Power off the device, connect the Mi Box and computer using USB male to male cable. Open AMlogic burning tool load the mdz16ab.img file in burning tool, uncheck the erase boot loader and in erase flash select Normal erase and click on start.
5. Power on the device by holding BACK+OK buttons, you will see in burning tool that flashing process will start and it will take around 4 min 25 sec to flash the image.
6. After the flash is 100% completed, click on stop in the burning tool and disconnect the USB cable and power off the device.
7. Insert the USB drive with update android 8 2562 which we have created in the first step. and turn on the device by holding BACK+OK buttons until you see installing update screen with big circle. That's it your device is downgraded to android 8.
8. Device will restart 3-4 times during the installing update process and do not remove the USB drive until you see rotating android logo.
Note:
The moment you connect the device to internet it will download & install android 9. So before that you need to fill the internal store till it has below 400MB. I left 1GB space in the box and connected to internet after 5 mins it said preparing for installing update, then i turned off the device and did a factory reset from settings and filled the space below 300MB for safety and connected to internet. Through ADB install any file explorer and through USB drive fill the device internal memory. There is no other option left.

Happy Flashing.4My English is very poor, I use Chinese, with the original Chinese tutorial. Use GOOGLE Translate to English to share the downgrade process. The process is very simple. I hope to help people who want to downgrade from pie to oreo without losing the DRM copyright, WIFI, Bluetooth, and Netflix SN.

Happy Flashing.
With the last update build 3934, I can't install apps from the external HDD, I have permissions but says there's an error in the analysis of the package. And I can't write content to the HDD either. This version also added extra apps, ACR and a bunch of useless crap.
So, I followed the downgrade tutorial one more time BUT in step 7, I used an usb drive with Android 9 build 2926 (the first one for Android 9, at least available, can be downloaded from the thread in this site). And everything went great too. I successfully downgraded my MiBox from Android 9 build 3934 to build 2926.
