but that doesn't require you to downgrade, if you want to run some older versions of applications, you can just extract the binaries from older firmwares, and use inception or other exploits to install them over the new binaries in PR1.3.

A reason to downgrade in Pr 1.2: to have a usable autocorrection for French
Fortunately, we have the Swype keyboard but it's a sad situation.

However it is possible if:
a) you have R&D certificate in your device (which only Nokia employees have)
b) you use software downgrade exploit (which is not publicly available)
It's not even possible in the Nokia factory , so i don't think, it will never happened. Been there done that... I think there could be some software to do so, but it's only available for Maemo/Meego team.

design problem

you need be in normal mode (not open mode) and clean/erase the cert-sw..., and you can downgrade the APE side (not the CMT side)

Can you share the guide to do that?

In normal mode you have read&write access to CAL. So I think downgrade can be done with writing some old cert to CAL, then rebooting & flashing old version of fiasco.

I have Dev environment, but I have not libcal-dev and I am not so experienced with C. Do you have binary of cal_write_block?
