I try to downgrade firmware. Procedure looks very simple but i'm unseccessful in it.
/system resource> print
version: 6.40 (stable)
build-time: Jul/21/2017 08:45:31
cpu: MIPS 24Kc V7.4
board-name: hEX PoE lite
As you can see my current version is 6.40.
I want to downgrade it to 6.29.1
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?
