Now that the bootloader is unlocked, I can boot TWRP simply with fastboot boot blutwrp.img, avoiding the potential of a bricked phone. Wish I'd done this a long time ago. I'm now using TWRP and adb pull to backup partitions on the phone and save them to my laptop. Then I'll try removing some more of the bloatware.
