  1. Start with the calculator OFF
  2. Connect Erase (J36, lower left) to Vcc (J31, upper right) and leave it connected.
  3. Press ON. Calculator will turn on.
  4. Press RESET. Calculator will turn off.
  5. Disconnect the Erase connection.
  6. Press ON. Calc will look dead but it is really ON.

You are now ready to flash with MySamBa.

When the file transfer is complete, press RESET to turn the calculator off.

It worked! I just flashed a new 20b to become a 34s. :-)

Just to be sure: is it possible to use the standard update procedure (ON+D D, ON+S S) to turn a 34s into a 31s and vice versa? I am asking because I wonder what happens to the saved settings that are usually restored after an update. The backup included all programs and data registers, but all this (resp. only a few data registers) is not supported by the 31s.

BTW1: I do not see a significant difference between the 30b and 20b displays.
BTW2: Yes, IMHO the 30b keyboard is by far the better one.
