On Ledgers support page for upgrading the firmware (
https://support.ledger.com/hc/en-us/articles/360002731113) it states:
Firmware versions below 1.3.1 cannot be updated with Ledger Live. Please submit a support request to get a replacement device.

There is also a general recommendation by Ledger to update the firmware regularly (see
