How to recover Pysense 2.0X Flashed with Firmware for Pysense 1?

Re: I flashed old firmware to Pysense 2.0 boards

In my haste to update firmware for my Pysense 2.0X board, I also flashed the firmware for the v1 Pysense board. My Pysense 2.0X board is now not functional. I have downloaded v15 of the Pysense 2.0X firmware referenced in the thread above, but dfu-util is unable to apply this and my Pysense board appears to be bricked.

Any suggestions?

I must have totally missed your message. I posted the firmwares on the forum some time ago for a different user in your situation, but now we have the latest firmwares published in the documentation: https://docs.pycom.io/updatefirmware/expansionboard/

Best,

I read that with the help of MD5 the sums of the NCK code itself, but how to find it out I don’t know any program, when I tried to enter the issued MD5 to say ERROR, I changed the firmware. AT ^ CARDLOCK? answer ^ pimion CARDLOCK: 3,0,0 .
