(Resolved) RAK4361 RAK 4360 Bootloop: LFS assert: head >= 2 && head <= lfs->cfg->block_count

Hi, I have an issue with the RAK4631 running Meshtastic FW.
At some stage the remote site went down and I finally got to taking a look. Seems there is some error preventing it to boot.
I re-flashed firmware and same issue.
Any advise?

Boot log:

Resolved:

Factory erase then re-flash fixed the bad firmware.
This is for the RAK4630 and RAK4631

  1. Download:
    https://github.com/meshtastic/firmware/releases/download/v2.4.0.46d7b82/firmware-2.4.0.46d7b82.zip

  2. double tap the reset button on board

  3. extract: Meshtastic_nRF52_factory_erase_v2.uf2

  4. drag and drop it as per normal firmware update

  5. open a terminal and hit any key to accept the “press any key to flash”

  6. upload new firmware and done.
