oy, sorry to hear about the trouble – we haven’t heard any similar reports, but you can still access all of your files by inserting your sd card into your computer and looking at the rootfs drive under /home/we/.
if you need to get up and running quickly, i’d suggest grabbing the files you need and doing a fresh flash. if you can, please keep maiden open when you do the next update so you can catch any errors – please keep us updated!
