You need Boot2 3.1.

Check your hardware revision code - it's the last letter in the P-0000X code on the back on the right of your serial.
For example, here is a hardware revision 'J':

If your hardware revision is 'I' or lower, you can reflash Boot2 3.1 using an external USB/TTL interface.

If your hardware revision is 'J' or greater, you can't. You need to replace the calculator or at least its motherboard by older revisions.
Older motherboard revisions can be bought from China: https://tiplanet.org/forum/viewtopic.ph ... 21&lang=en
