    Hi Joseph

     

    I believe its due to middle of upgrade or improper power down cause loader file to corrupt,

    you need to upgrade the loader file and U-boot via TFTP.

    Do you get a prompt where you an interupt the loop before it repeats?

    If so what prompt are you at?

     

    Do you have another SRX240 you can use to create a bootable usb for recovery?

    You can insert a usb and run a snap shot to the usb.

    then boot this device from that usb and run a install with format to the internal drive from there

    so when i turn it on it gets to 


    U-Boot 1.1.6-JNPR-2.4 (Build time: Aug 31 2012 - 12:15:03)

    SRX_240H2 board revision major:2, minor:9, serial #: ACKV4878
    OCTEON CN5230R-SCP pass 2.0, Core clock: 600 MHz, DDR clock: 333 MHz (666 Mhz data rate)
    DRAM: 2048 MB
    Starting Memory POST...
    Checking datalines... OK
    Checking address lines... OK
    Checking 512K memory for U-Boot... OK.

     

    it hangs here and loops 

     

    but no prompt is shown, i do have another srx240 which works, how do i use create a bootable usb and snapshot from the other srx240
