Who Can Give Us Some Info About Unlocking Methods In General ?!

I like to know some real info about how programmers deal with phones
like i see they can deal with bin files and read simlock code from it and so on

all i need is general info not to make unlocking program but just to add it to my personal info

so if anyone can explain here some general info that will be great

few things which i know i can tell.

to unlock or communicate to phone

you need to know platform. that's the first thing.

you need to know how to deal with phone to repair something . that's the protocol of communication.

you need to know phone will work with calculated code or stored code at some where at phone. that's the algo third step.

you need to know that if phones commands which its accept crc / check sum which need to send with commands without it no reply you can get.

to unlock some phones its really easy in developing like reading code in stored area. and typing code at phone.

to unlock high security base phones like sagem which use calculation method. to unlock this type of secure platform need to calculate correct code which is not not easy at all.

to unlock some phone which have firmware read protected need to learn about there bootloader and unlocking at boot mode/flash mode.

but there are many things its depend.

Take some light reading:

If you can read and understand that bad boy, your are on a first step of the ladder

ho ho how can i forget.

copy
paste
usb and serial sniffer

this are tools many guys are using this days. inserted of doing there brain work.

hehehehe

The central of unlocking software developement is cracking (reverse engineering), you must to know how to develop first.

Indeed It is not Easy and that is something I know long time ago
but what is very interesting here is the the methods u explained here they are many and i am sure there are more and more as each single day we got new things in programming

so I like it so much to get this great info

thanks to all who posted here bro

It seems to me that the base start point to work with unlocking is to understand Assembly 100% then u can start look here and there for other things
as CPUs understand only this way ( Assembly ) so u have to give and take from it only by this way

or i am wrong in this?!?!

Probably the best way to start is to learn a programming language (higher level) from beginner level.

The reason is, if you analyze the phone ASeMbly code, find a solution- how can you implement this if you dont know how to write your program?

Also it will help you get into the "programming mind set", analytical and logical ways of thinking.

where can one learn all this? i need to learn from a good programmer.

Dave.W · 03-12-2009, 10:07

You can learn on your own, in your spare time. No need for a teacher.

Choose a language, something like VB .NET is a nice choice. The tools for making programs is free to download http://www.microsoft.com/Express/VB/ and you will be making nice looking applications in no time.

Then do a google search for forums (if you search google for "VB .NET forum" you will et many hits). Probably better is to buy a nice book and work through the chapters in your spare time.

Good luck!
