Who cares about closed mode?
Just flash open mode, downgrade and the flash anew PR1.3 and you are back to stock
So, to test. I flashed closed, stock FW.
Anyways. chown root:root /dev/mtd1 solved that.
Now, "Service is under maintainance, try later" when I try to DL "DFL61_HARMATTAN_10.2011.34-1_PR_LEGACY_001-OEM1-958_ARM.bin"

Hmm no luck in closed mode
(devel-su and develsh before issuing cal-writer command)
Code:Debug: 2: cal_init() called Error: open(/dev/mtd1): Permission denied Couldn't open CAL for writing

IIRC there is no exploit for downgrading CMT part of firmware... Also no way for N900!

This needs not only closed mode, but it has to be installed using elevated rights (what's the modern replacement for Inception? aegis-install as I recall). It should be installed with com.nokia.maemo origin.

I did (with my cert in /root/cert.bin)
devel-su
develsh
chown root:root /dev/mtd1
cal-writer
And it did write the 'old' cert from cert.bin
then, of course, I did
chown cal:cal /dev/mtd1
to restore org permissions
Will try, if / when, Nokia servers allow download of FW again (says service under maintainance)

So you've been able to downgrade? Please report.
