Firmware upgrade issues with 6.48.5 and 6.49

Hi guys

I never had issues with any device new or old performing upgrades and i’ve done it across multiple platforms from CCR to RB750, csr, etc
I even jumped from really old ROS and no issue whatsoever even on devices i actually prayed to fail so we can replace them with newer models.

But lately i had at least 3 devices which broke after the firmware upgrade.

So the procedure i always used:

  1. Upgrade ROS to the long term or stable (6.58 or 49 in this case)
    No device crashed after the RROS upgrade … all worked without a problem
  2. system routerboard upgrade to also upgrade the firmware, no error here, but after the reboot i had 3 devices that remained stuck in a rebooting loop
    I had one old RB750GL - the update worked from 5.14 - > 6.40 flawlessly even the firmare. Update to ROS 6.49 was fine, but the firmware upgrade broke it
    Same happened to other 2x RB2011 these were on Ros 6.47.x and 6.48.1. Worked after ROS and got bricked after firmware upgrade.
    We tried to keep the reset button and plug in the power, but that did not help
    Since those 3 failures (2 were clients and we had to replace with better devices on our dime) i am really reluctant to try upgrades on clients who have CCR1009 or other expensive devices
    model: CCR1009-8G-1S
    serial-number: 66C30589331B
    firmware-type: tilegx
    factory-firmware: 3.27
    current-firmware: 6.48.1
    upgrade-firmware: 6.48.5
    Should we stop doing the firmware upgrade? Only update ROS?
    What is the official position with these upgrade and how well are these actually tested?

Thank you

Hi,
I allways update firmware the moment ROS updates with a second reboot.
So, the jump in firmware is never bigger than the jump in ROS.
I upgraded about 20 devices without any problems,
lots of mipsbe (RB750, RB951, RB962, CRS125, RB2011)
some ARM devices (RB1100, waprac)
1 tile (CCR1009)
no problems seen.

I would generally advise upgrading the firmware at the same time, but just be careful about the release. Even if it is a new long term or new stable, do not assume it is working properly - wait at least a few weeks for the early reports from users before pulling the trigger, and do some tests in a lab and with some pilot locations at first.

There are two known issues with the new firmware in 6.49 (the second also impacts 6.48.5):

  • CCR1xxx very slow boots - up to 10 minutes
  • Upgrade from ancient 6.41.4 RouterBOOT firmware causes reboot loop - if RouterBOOT firmware is newer than 6.41.4 prior to upgrade, this supposedly does not happen.

Thank you mducharme

Probably why it happened.
