If you get a prompt, you can send a reset and then save.
The strings at the beginning are at the wrong baud rate.
The rtc mem data means it can read the last time from flash, but it sounds like there are other issues.
Best bet is to use the flash tool, with the erase option. This will blank out everything, then reflash and it should be fine.
