By the way, the way I get into Fastboot mode reliably is adb reboot bootloader. No combination of buttons ever gets me there except by accident, and I'm not absolutely sure it's ever worked.
I might have gotten my phone back. I had already downloaded a system image off the web (firmwarefile.com), so I did adb push ../Blu_D110L_MT6580_V22_GENERIC/Firmware/recovery.img /tmp/, and from TWRP, Install | Flash image | /tmp/recovery.img | swipe. It seems to have worked, but I seem to have a factory image, nothing installed. Let's see if I can get it working again before heading south for the winter.
