Flashing new firmware... can it be done?


  • I have tried flashing meshtastic 2.7.15 via both Bluetooth and Serial and "404 cannot connect/download."

    Is this device "locked" or only stable with the outdated FW? 



  • nvm, figured it out in another forum.


  • got a link ?   Was this a special firmware for the Spec5 ? 


  • @John we use standard Meshtastic Firmware


  • I can't get my device into DFU mode to save my life...  I've tried all the "tricks"... did you struggle in any way to flash it ? 

     

    The console log on https://flasher.meshtastic.org/ shows the following.

    the screen is blank, AFAIK this means its in DFU mode, but still unable to flash it
