Not possible; search before creating new duplicate threads...

Not possible is the default answer for marcaurell.

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)

Another option would be to deploy a 1.2 rootfs backup, and flash the kernel using a dd-made backup.

Not the brightest of ideas, as I still don't know why people would want to downgrade, but hey, at least it's an idea.

I think someone did it by using hexedit to change the version number in the older image.

Re: Firmware downgrade from 1.3 to 1.2 possible
 

that will never work, since if you edit any bit on the image, then signature checksums will fail.

But anyways there really is not valid reasons to downgrade, other than sometimes you might want to go on PR1.1 if your ovi store application entry happens to fail the QA (and even then you can use RDA), but if your not ovi store app developer then there really is no reason.

IICR nemomobile requieres pr1.2 to be flashed

but i am curious about those downgrade hacks ...

Thank at All for answers and suggestions.

Re: Firmware downgrade from 1.3 to 1.2 possible
 

well I have runned nemomobile on PR1.3 so I don't think that there is any limitations, all the instructions are just for PR1.2.

Perhaps people might want an email client which shows unread counts reliably or a web browser which doesn't aggravatingly blank the address bar when it fails to load a page, two major regressions in what was supposed to be a bugfix release.
