    Is it possible to upgrade BIOS in SRX300, I tried to execute:

    root@rudn> request system firmware upgrade re bios
    ^
    syntax error, expecting <command>.

     

    root@rudn> request system firmware upgrade ?
    Possible completions:
    fpc Upgrade FPC ROM monitor
    pic Upgrade PIC firmware
    vcpu Upgrade VCPU ROM monitor

     

    As for SRX550 i see:

    junoadmin@srx550> request system firmware upgrade ?
    Possible completions:
    fpc Upgrade FPC ROM monitor
    pic Upgrade PIC firmware
    re Upgrade baseboard BIOS/FPGA
    vcpu Upgrade VCPU ROM monitor

     

    Also I suppose that there is no Backup BIOS in SRX300:

    show system firmware compatibility
    Part Type Tag Current Available Status version version
    Routing Engine 0 RE BIOS 0 3.1 2.9 OK
    Routing Engine 0 RE BIOS Backup 1 0.0 2.9 OK

     

    May be the reason is that Current BIOS 3.1 > Available BIOS 2.9

    I didn't upgrade anything in srx300, the device was unpacked some days ago.

    You need to upgrade your Junos to a later version where a newer firmware for the bios is available.

     

    Example from a SRX300 where I upgraded the bios from 3.3 to 3.6:

     

    --- JUNOS 18.4R1.8 built 2018-12-17 03:29:17 UTC
    user@fw> show system firmware compatibility
    Part             Type              Tag Current   Available Status
                                           version   version
    Routing Engine 0 RE BIOS           0   3.3       3.6       OK
    Routing Engine 0 RE BIOS Backup    1   3.1       3.6       OK
    
    user@fw> request system firmware upgrade re bios
    Part             Type              Tag Current   Available Status
                                           version   version
    Routing Engine 0 RE BIOS           0   3.3       3.6       OK
    Routing Engine 0 RE BIOS Backup    1   3.1       3.6       OK
    Perform indicated firmware upgrade ? [yes,no] (no) yes
    
    On successful completion of the upgrade, the new bios will take effect after the box is rebooted.

    Routing Engine 0 RE BIOS           0   3.3       3.6       UPGRADED SUCCESSFULLY
    Routing Engine 0 RE BIOS Backup    1   3.1       3.6       OK

    Dear Jonas, thank you very much! Could you give me advise on the problem in topic 

    https://forums.juniper.net/t5/SRX-Services-Gateway/SRX-550HM-and-JunOS-15-1X49D150-J-Web-has-broken-interface/td-p/458726

    Before JunOS 15.1X49D150 I tested JunOS 18.1R1.9 on this device and have other problem with J-Web.

    https://forums.juniper.net/t5/SRX-Services-Gateway/SRX-550-upgraded-to-HM-and-JunOS-18-1R1-9-J-Web-doesn-t-work/m-p/368071#M51107

    18.1 is not recommended by JTAC for SRX I mentioned this just for information.

    I see that current JunOS wasn't tested well on old devices. I hope that this bug will be fixed in next release, I've send this info to support@juniper.com, but no feedback yet. 

    So I shall try previous versions, for example D110 is the minimal version with necessary features.

    Another way is:

    1. Make a snapshot of D150 to USB,

    2. USB: Copy classic theme CSS to classis theme folder

    3. Recovering from modified USB partition

    I've just upgraded to 15.1X49-D150.2 and BIOS became upgradable as well as Backup BIOS appeared. So it was a software issue.
