building an image
 

Hi,

How is it possible to modify a firmware image please?

For example, how can I open or unpack or mount the image
"DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_001-OEM1-958_ARM.bin" ?

And then replace some files, and in the end rebuild a new image for flashing?

TIA for any hints, Peter

no, please don't do it. everything you can do without flashing.

Unpacking goes with old flasher 3.5 (N900), parameter -u or --unpack.
But getting it together not.

This might be possible with pali's open flasher 0xffff, but I am not sure now. Just go ahead.

BUT you know how to deal with AEGIS?

You mean a cfw :eek:
coderus was on of the kingpins !

Therein lies the main difference between Symbian/Android and Harmattan. You don't need to jump thru hoops to change some system files by unpacking firmware then flashing a cfw.

No, it seems Aegis is something very complicated. It seems to be difficult to build a cfw for the n9, and I don't want to take the risk to brick it.
I just had a little hope, that there would be something as easy as "make" for building a cfw. (I'm used to OpenWrt.)

(When I bought the N9, I thought, that it would be possible to build a cfw from source ("make world"), just some files would be "binary blobs" from Nokia.)

Thanks for your help, Peter

Re: building an image
 

Once I had modified (not creating from scratch) harmattan firmware and built a new slightly modified kernel; and you can find the tools to unpack/re-pack firmware in this forum. However, as being said, it's usually better to not do it; unless you are required to.

But, building a firmware from source could have lots of issues that you should deal with yourself, as nobody has done it (at least, publicly!).

Hi,

Probably the least risky way is flashing original firmware and then modifying individual files step by step. So I only need backups of modified files.

But it seems, that there are dozens of original firmwares and there is no more official download location? I have the firmware for product code 059J228. But can I use it for an N9 with another code?
Or should I buy only a model with same product code?

TIA for any hints, Peter

There seems to be problem: I still rely on downloads.maemo.nokia.com to get the developer-mode. What happens, when this site disappears?

Or am I missing something?

Here in detail how I would like to prepare a new N9 (even some years in the future, when there is no more nokia.com):
- flash device with original firmware (I have flasher and the firmware)
- enable developer-mode (here it seems, that nokia.com is needed)
- copy packages and other files from my backups to device with ssh

(Perhaps I really need to switch to uniboot, but I would like to keep it as basic as possible...)

Ok, I've one idea: simulating downloads.maemo.nokia.com on a local server. But other (probably better) ideas are very welcome!

TIA for your efforts, Peter
