Hello

I want to flash FW on my 4010p EU v2.3, it's working and can be queried normally :

I can re-flash currently installed firmware with plcboot But when i try anything newer i'm getting message :

What that Minor Version Mismatch exactly means? There's some version checking during nvm flash? What can be done to flash it finally?

Thanks in advance

As far as I can tell, this message comes from incompatible PIB files. I get the same error when trying to flash from a MAC-QCA7500-2.0.0.367-02-20140711-CS firmware on QCA7500 to anything later like MAC-QCA7550-2.2.3.32-00-20161104-CS (or MAC-QCA7550-2.10.0.32-01-20200626-CS just recently). When extracting the pib file in my case, the old file is 20888 while newer fw's pib file length is 22344.
