SRX

Hi All,

I ran into a problem while trying to upgrade to junos-srxsme-12.1X46-D30.2-domestic.tgz.

After upgrading, when I performed the reboot; the firewall went into the u-boot and asked me to issue nand_format.

After formatting, it showed up as:

can't load '/kernel'
can't load '/kernel.old'
Press Enter to stop auto bootsequencing and to enter loader prompt.

I saw this problem reported earlier and tried a number of things:

1. I formatted a USB, copied the upgrade file onto it and tried to install from it but it didn't work.

Note: I formatted the USB from DOS prompt, though not as a bootable media. Just a plain format.

2. Somewhere I saw the following commands, just tried my luck:

=> setenv oct.net.init
=> saveenv
=> reset

Didn't work as well.

3. Tried to install with the install source file:/// command, didn't work as well.

4. Finally I tried another solution found somewhere

=> setenv boot.current alternate
=> boot

Now the reboot ends with a prompt like this:

Memory: 512MB
Un-Protected 1 sectors
writing to flash...
Protected 1 sectors
No bootable media found. Entering loader prompt.

Type '?' for a list of commands, 'help' for more detailed help.

Any suggestions would be helpful.

hello ,

I see that you have tried the possible proceedures , so now to recover the device , kindly do the snapshot method of taking the snapshot from one device and boot the non-working one from it .

So if you have any other device running upgraded or old version , please take the snapshot from that device and make this faulty device boot from it .

1) Connect USB to working device and run :

> request system snapshot media USB

2) once the snapshot is taken , conenct the USB to faulty device and reboot .

3) once it boots from the UBS copy the snapshot to faulty device :

> request system snapshot media internal

Then try to upgrade again

 Shyamraj,

Now try the install via the command;

If that does not work , you could try to reload the device from a usb after you take a snapshot from a working device onto a usb.

Another thing you could try is issuing a reload/boot from the loader prompt and see if the device comes up.

Hi Joses and ssn,

I tried to upgrade from TFTP and it worked fine (unexpectedly).

Here's the article I followed, for reference:

Thank you for the support !
