So, my SP3 just bricked, and it wasn't the borked build that got pushed to WU by error.
I was on 16913 (fast ring) and when 16919 came it just failed to update. It wasn't the first time it happened (and I literally had only office and Visual Studio installed, so not sure what caused it wither), and the last time I could fix it by doing a restore (even the keep my files one worked), but now they would fail too.
I thought it could be something in that build and decided to rollback to the previous version (using the builtin windows tool)... Everything seems to be fine, the process completes and when it restarts the screen just flashes a few times and boot to bios. The shortcut to boot in recovery mode won't work, The Surface logo appears, but then it also flashes a few times and go to bios.
No problem, I recall Ms used to provide recovery images for the Surface line. I did it step by step, created a pen drive for recovery, changed the bios setting to boot from usb first. And now the logo apepars as it's reading the pen drive, but after a while it just stops reading and the screen flashes and the subsequent boot to logo repeats.
Edit: I guess it wasn't booting from pen drive due to secure boot. I disable and now it seems like it's going to be able to do something.
Edit2: FUUUUU even when trying to restore from the external media it's giving me an error after staying in the Recovering This PC screen for a while. Recovering from Cloud doesn't work either, neither any of the other options.
I guess now I'm really screwed?
