Mikrotik LDF-5ND Upgrade Issue
Hey all,
I have an LDF-5nd "(ath79/mikrotik) mikrotik (routerboard-ldf-5nd)" that has faithfully been in service for years, and has been up for 182 days.  However, it has been unable to upgrade past 3.25.2.0.I've tried the intermediate releases as they came out, as well as the current 3.25.8.0.  It just says 'error' and doesn't update.  It downloads the firmware listing, but just errors out when you click 'fetch and update' saying "ERROR: Unknown error".  All other nodes are upgrading perfectly via this method.  I also tried the manual download to computer and upload to the node, and it just silently fails, no error message.  The node is sitting a almost no load, and has free ram and flash.  I have pulled the support data, but don't know what to do with it.  Should I just upload it here, or email it to someone.

The node name is KV3T-5G-LDF5. 

Thanks in advance for the help.

Mikrotik LDF-5ND Upgrade Issue
Hi, Casey:

Another way is to SCP the sysupgrade.bin file to the /tmp folder on your ldf.
Then ssh into the node and enter
sysupgrade /tmp/aredn-20250827-ffa4b3ee-ath79-mikrotik-mikrotik_routerboard-ldf-5nd-squashfs-sysupgrade.bin

From there you should see success or an error message.

root@NC8Q-R2H7:~# sysupgrade --help
Usage: /sbin/sysupgrade [<upgrade-option>...] <image file or URL>
       /sbin/sysupgrade [-q] [-i] [-c] [-u] [-o] [-k] <backup-command> <file>

upgrade-option:
    -f <config>  restore configuration from .tar.gz (file or url)
    -i           interactive mode
    -c           attempt to preserve all changed files in /etc/
    -o           attempt to preserve all changed files in /, except those
                 from packages but including changed confs.
    -u           skip from backup files that are equal to those in /rom
    -n           do not save configuration over reflash
    -p           do not attempt to restore the partition table after flash.
    -k           include in backup a list of current installed packages at
                 /etc/backup/installed_packages.txt
    -T | --test
                 Verify image and config .tar.gz but do not actually flash.
    -F | --force
                 Flash image even if image checks fail, this is dangerous!
    --ignore-minor-compat-version
             Flash image even if the minor compat version is incompatible.
    -q           less verbose
    -v           more verbose
    -h | --help  display this help

backup-command:
    -b | --create-backup <file>
                 create .tar.gz of files specified in sysupgrade.conf
                 then exit. Does not flash an image. If file is '-',
                 i.e. stdout, verbosity is set to 0 (i.e. quiet).
    -r | --restore-backup <file>
                 restore a .tar.gz created with sysupgrade -b
                 then exit. Does not flash an image. If file is '-',
                 the archive is read from stdin.
    -l | --list-backup
                 list the files that would be backed up when calling
                 sysupgrade -b. Does not create a backup file.

Thanks Chuck.  This worked. 
Thanks Chuck.  This worked.  Not sure why, but it upgraded.  I have a few more that are having a similar issue, so I'll go do this same procedure with them.  One question, of course the log that I got was:

... performing upgrade, shutting down all connections...
[broken pipe]

For my own education, If I did run into an error, where would I go to see the error message?

Thanks again!

Hi, Casey:

Using the sysupgrade command in OpenWRT is now contra-indicated.
Use the sideload method.

Simply browse to the folder containing the sysupgrade firmware and enter:
scp -P2222 aredn-20250902-251de847-ath79-mikrotik-mikrotik_routerboard-lhg-5hpnd-xl-squashfs-sysupgrade.bin root@nc8q-mvhs-kettering.local.mesh:/tmp/local_firmware
Then browse to the remote node and click: Fetch and Update.

3s, Chuck

Interesting that your LDF-5nD
Interesting that your LDF-5nD is having issues.  My LHG-5nD has given me upgrade fits for years.  Even if I select the option for dangerous upgrade, it often fails.  Sometimes it is more reliable if using a linix computer vs a Windows computer, and sometime I have to use the sideload procedure Chuck mentioned.
It's the only one of my nodes that has that issue.
