I thought I would post here with a warning that auc looks to be delivering non-working SNAPSHOTs requiring uboot recovery to get the router working again, at least for me. I am flashing a GL.iNet GL-MT6000.
Luckily, accessing the MT6000's uboot recovery is just a matter of powering up the router while holding down the reset button for 30 seconds, and I can re-flash a working image.
For now, I am using a current pre-built base sysupgrade image to update.
This started yesterday when updating to SNAPSHOT r25215 and again today when updating to r25219. Not sure if this is happening to anyone else?
