My instructions for flashing TWRP don't work on my computer in Petaluma. One problem was that SP Flash Tool couldn't connect to /dev/ttyACM0, so in one xterm I ran for i in $(seq 0 300); do echo try $i; ls -l /dev/ttyACM0; sleep 1; done while following the steps. It showed me that the tty's group owner was dialout, so I added myself to the group using sudo usermod -a -G dialout jcomeau, logged that xterm out, and started a new one (because I know of no way to refresh groups once you're logged in).
Anyway, that didn't fix it, because the tty stays open only until Android starts booting, about 3 seconds later. Not enough time I guess. I wonder why that didn't happen in Mexico last January.
