Save the previous version to the U3 chip before the new upgrade download starts. If it fails for any reason then restore from the U3 chip previous version.
Maybe the firmware upgrade cant always do the auto recovery as it doesn't necessarily know it is broke; this actual use case in this thread is a good example of that.
But to recover then you could have some ring-fenced code that could recover from U3. then to initiate the restore retrospectively you just set a Boolean at a memory address X and reset the system and it auto recovers.
That's my suggestion anyway.

The EEPROM fitted is only 32KB.
