Downgrade

RouterOS Beginner Basics

Hay all.

I try to downgrade firmware. Procedure looks very simple but i’m unseccessful in it.

My device:

/system resource> print
uptime: 3d10m52s
version: 6.40 (stable)
build-time: Jul/21/2017 08:45:31
factory-software: 6.35.4
free-memory: 41.4MiB
total-memory: 64.0MiB
cpu: MIPS 24Kc V7.4
cpu-count: 1
cpu-frequency: 650MHz
cpu-load: 2%
free-hdd-space: 5.0MiB
total-hdd-space: 16.0MiB
write-sect-since-reboot: 102289
write-sect-total: 103681
bad-blocks: 0%
architecture-name: mipsbe
board-name: hEX PoE lite
platform: MikroTik

As you can see my current version is 6.40.
I want to downgrade it to 6.29.1

Step-by-step

  1. From official website I downloaded "routeros-mipsbe-6.29.1.npk
  2. Using winbox i copy this file to /file>
  3. Go to /system package downgrade
  4. Reboot device
  5. Version doesn’t change. Stil 6.40

What I do wrong? Any ideas?

You can see that minimal supported RouterOS version is “factory-software: 6.35.4”. You can not downgrade router below this version.

even with netinstall?

I don’t have any ways to downgrade it, do I?
I found out that certificate scep client doesn’t work with other vendor CAs in new versions (after 6.3).
Now I’m in situation when it’s impossible to get certificate in 6.40 and at the same time with no possibility to downgrade to working version.
What I can do? Perhaps I need wait new version of software?

Yes, of course. Device can not be downgraded to older version than factory version since it would not work 100% reliably (for example, no drivers for memory installed, etc.).

If there is some software level issue which requires downgrade in order to work as suspected, then please contact support@mikrotik.com and report the problem. We will try to fix the issue if there will be any so you could use latest version.
