Details on getting this running, now that it was finally released!
The instructions & system.img can be accessed in XDA: [A13] Pixel Experience GSI for Surface Duo.
I chose to flash the system.img versus the DSU Sideloader method. It’s been a little while since I’ve played around with Android & custom ROM’s so it took longer than usual to figure it out, but i did get it working. I’m making note of the process mainly for myself, but also in case anyone else needs a hint or two.
adb reboot bootloader
fastboot reboot fastboot
# fastboot getvar all # Don't need to do this really.
fastboot erase system_ext_a
fastboot erase system_ext_b
fastboot erase product_a
fastboot erase product_b
fastboot delete-logical-partition product_a
fastboot delete-logical-partition product_b
fastboot flash system system.img
There are some of the erase commands that you don’t need to run; it should only be the current partition ones you need, but i didn’t run into any problems by running them for both partitions.
Then, voila! You have your Surface Duo running Android 13, & the Pixel Experience ROM!
