I flashed 20180729 on a pico blx after being prompted to do so. On the last step (reapply settings) it went into a loop where it was unable to reboot the board (I had a battery attached - possible suspect.) I pulled the battery, and rebooted it by unplugging the usb key.
Now when I power the board back up, it seems to be in a boot loop on the firmware page; it appears to load firmware, and then immediately die, in a continual loop.
I can rescue and flash it successfully, but it's still looping on the firmware page. (Have also tried clearing board settings.)
Any ideas? Is it toast?
