That CCR1009 he's using might be new enough that the latest bugfix
doesn't have the necessary drivers. I don't see any problem trying to
load the version he wants via netinstall. As others have said, you can't
really nuke it. Even if you upgrade the RouterBOOT image and that fails,
there's the factory backup loader. You hold the reset button while
powering on to force the backup loader for that startup sequence.
There's a catch to that too. I had some old 493's running 5.25 and I
wanted to update them to 6.something. Luckily this was all on the bench
because the first one failed to boot. The loader could not find the
kernel. For the rest, I downloaded the latest RouterBOOT image for that
hardware and upgraded it in ROS 5.25 *before* upgrading to 6.x. For that
first one, I think I ended up upgrading the loader via serial which then
had no problem loading the kernel. Now the problem becomes the backup
loader not being able to locate the kernel image. The backup loader
can't be upgraded, but I think there's a special package you can load in
RouterOS (which obviously has to work) to get it upgraded.

I don't think it's wise to downgrade below shipped firmware.

*Subject: *[AFMUG] Can't downgrade mikrotik routeros
Hello all,
We are trying to install our normal mikrotik os version which is
6.32.4 since we have tested and found it the most stable.
The latest ccr router we received has 6.35.2 on it and we're not
having any luck getting it to downgrade to the stable bug fix version.
Some mikrotik forum posts say that you're not able to downgrade the
software below what it shipped with. I find this doesn't make sense
because the os didn't ship with the bug fix release, but rather the
more unstable "current" version.
Any advice how to downgrade when the normal procedure doesn't work? Is
it possible to downgrade to a version lower than what the factory
installed?
If not, would net install work to force the version we want? The way
it is now, there's not even a possible way to install the latest
6.34.6 bug fix release since it's lower than 6.35.2
Any help is appreciated. Thanks
