Yes, of course, I was missing this option:

"Applications -> Installations -> Allow installations from non-Store sources"

Sorry about the noise, Peter

Or should I buy only a model with same product code?

TIA for any hints, Peter
Well legally speaking it would be nice to be able to make a pure floss image and make it available for hackers ....

Do you have the name of the file for 059J228 ? is this the code in SIM tray mine is 059K117 ...

Yes, on the SIM tray. I have 2 N9s (one for using, one for repairing...):
- 059J228 is DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_006-OEM1-958_ARM.bin
- 059M8W9 is DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_001-OEM1-958_ARM.bin

Greetings to Rennes, Peter

Yes you cannot unpack, modify and repack firmware image as flasher checks that .bin is signed with nokia master key. (And that key is safely stored in some Nokia vault that nobody has access to).

So if you want to be able to update 'offline' or when official repository dies then procedure is to flash original firmware. Then enable developer mode, which can be a bit tricky if you dont have network or terminal access. But there are couple options:
- use serial cable to ttl serial pins that are located under sim to gain access to getty shell
- use mass-storage-mode to drop in couple debian packages for terminal, allow unknown sources, install terminal package. Use some dpkg exploit (like inception) to gain com.nokia.maemo privileges so you can install developer mode .deb and/or change repository url to your own custom one. And your ready to rock.

So don't worry if someday official repository dies, there are still multiple ways to flash and setup your favourity N9 device.

I did not try it, but shouldn't it be possible to install the original developer-mode.deb (and other original packages) without any exploit?
This is what I understand from the N9-user-guide...

Ok, thanks. I'm just a bit worried, because there are so many dead links to nokia web-sites. I've already downloaded several GB to my hard-disk, just to be sure, to be able to set up a N9 in the future.

With sparsify you can of course create fiasco's but when you flash the binaries, you will note that the device defaults to Open Mode. There's no easy way to fool the flasher to revert the device into Closed Mode without Nokia-signed binaries.

I'd go a bit farther even. I am fairly sure the original signing keys were destroyed with rest of the build infrastructure when the production line was decomissioned. A pity, though. It would not have harmed anyone now later, if some of the more closely guarded stuff would have leaked out...

Yes, it goes into open mode. I just wanted to make it clear that it is possible to flash an unsigned firmware into phone. But you're right, it'll be in open mode.

No, you are wrong, original developer-mode.deb needs to have active valid pgp signature on server side, so you cannot install it from commandline, or you can but if you install it with commandline, then its missing the developer-mode capabilities. Thats why system needs to be incepted before devel-mode can be installed from commandline.

To have flashed an open-mode kernel in advance may also be helpful!
