Is there a location on the site where I can download previous versions of firmware for routerboards along with x86 systems ? Also is it possible to downgrade from 6.12 to another version for example ?
Thanks,
Firmware for x86 system???
You intend BIOS or RouterOS?
Leave installed 6.12 and contact support@mikrotik.com if you encounter some problems,
or install 5.26.
