A suggestion for an entry.
It seems it may be possible to allow downgrading n9 (N950?) firmware, by inserting old certs, extracted from mtd partition. At least @feuerplatz seems to have succeeded in doing so.

It would be cool to have an application developed, which could extract all older certs from mtd, store them, and the write (from user choice) a desired older cert to cal area in mtd partition. Thus allowing those who accedentially flashed Chinese SW to 'downgrade' and reflash other region firmware.

I could try, but believe we have more skilled devs here on the N9 than myself.

As a side-note. I will personally try to dig up a good reward (besides those devices already promised) to anyone who successfully completes such a task. Idea for price Jolla phone or perhaps another N900 ? let me know.
