Cant flash on shelly 1pm plus with fw 1.4.0

Open breakingflower opened this issue 6 months ago • 1 comments

Hi

Following the guide, I have updated a shelly 1 plus pm to latest shelly firmware image Tried flashing with latest zip from releases. Getting error

  {
    "ts": 1722589187.248,
    "level": 0,
    "data": "shelly_ota.cpp:261      Aborting update: backend error while processing data: -1 (-11: PT update is req'd but unsupported by the new fw)",
    "fd": 1
  },

Full logs diagnostics-shelly-plus1pm-debug-log.txt

I've tried the following:

  • downgrade (does not work, variety of errors with OTA and zip)
  • reset to factory and try again
  • OTA

I could not find any related articles, any advice is welcome.
