- TWRP image: twrp.img
- Parted: parted
- Platform Tools from Google (ADB and Fastboot)
- A PC.
THIS WILL WIPE ALL YOUR ANDROID AND WINDOWS DATA
We don't take any responsibility for any damage done to your phone. By following this guide, you agree to take full responsibility of your actions. We have done some testing, but this is AN EARLY PREVIEW and things can go wrong.
PLEASE READ AND BE SURE TO UNDERSTAND THE ENTIRE GUIDE BEFORE STARTING
A normal Surface Duo, with Android only. Just like you had it before installing Windows. If you haven't broke anything else in the meantime.
Android will have access to the whole memory back again.
- Reboot your phone to the Duo Bootloader: Press Volume Down + Power until the Microsoft logo appears on the left, then release the power button and keep pressing the volume down button until the bootloader appears.
- Plug your phone to your PC, open a command prompt and run the following command:
fastboot boot twrp.img
You will now boot to TWRP. Reminder that touch doesn't work on TWRP for now, so you'll have to work through your PC.
- Let's copy and run parted:
adb push <path to parted> /sdcard/
adb shell "cp /sdcard/parted /sbin/ && chmod 755 /sbin/parted"
adb shell
parted /dev/block/sda
print
You'll get a list of partitions.
- Make sure that partitions 6, 7 and 8 are your ESP, Windows and userdata partitions. We'll assume they are for this guide. If they aren't, take note of these numbers and use them in the next steps. Please make sure these are right, or you'll end up bricking your Duo.

rm 7
