Ive been looking into the way the update service works with a view to finding some way of fooling it into thinking you have a generic unbranded k750i.

I've written a program which intercepts the communication between the flasher program and the ericsson servers.

What I need now is a few K750i users who would be willing to run this piece of software and send me the results. A few users from each network and a mixture of branded/unbranded phones.

With any luck it should be possible to identify enough about the protocol to fool it into updating our branded phones.

I am attaching images of the initial query and response packets sent from the flasher software when I attempt to flash my orange branded phone to demonstrate the sincerity of this post.





Send me a private message if you are interested in helping out, stating your network, branded/unbranded, the current version of your firmware and a contact email address.

What about starting the update service with a unbranded phone attached to the cable and then swap it during the download

Are you saying that you are reverse engineering a piece of proprietary software and then posting that you are doing this in a public area? Is this what you are doing?

reverse engineering isnt illegal as far as I know. if it were then all emulators would be illegal.

Open office also reverse engineered the microsoft office file formats and they have all the information they acquired publicly available.

Reverse engineering is not illegal?

Whatever dude. Think what you want. Good luck. I am bailing on this entirely lame thread.

I refer you to EU directive 31991L0250 (Council Directive 91/250/EEC of 14 May 1991 on the legal protection of computer programs)

http://europa.eu.int/eur-lex/[....]o?uri=CELEX:31991L0250:EN:HTML

and specifically the text

"Whereas a person having a right to use a computer program should not be prevented from performing acts necessary to observe, study or test the functioning of the program, provided that these acts do not infringe the copyright in the program;"

To me that means its ok to look under the cover to see how it works.

Why don't you go to SE and get the info if it is free for the reverse engineering?

Its a loophole. Like many sites who hack programs, like iTunes to improve them.

They're for educational purposes only, and since they dont infringe on the copyrights of the program, they havent harmed anyone.
