That is the firmware that is yielding the message:
Device xiaomi,mir3g-v2 not supported by this image
Supported devices: xiaomi,mir3g-v2 - Image version mismatch: image 1.1, device 1.0. Please wipe config during upgrade (force required) or reinstall. Reason: Config cannot be migrated from swconfig to DSA
Is there something I'm missing?
Edit: some guys have told me here that the wiki links are not working, and that I should use this image with the force flag. I'm going to try.
