***are you interested in developing boxes & software ***
 

For educational purpose only :

In gsm industry there are many boxes and dongle

we can help you answer the questions as well some tips how to
make your own software & how to protect if you can ..

There are many talended peoples still didnt get chance lack of
some informations we can help you on this



but we want new generation and more people understand how to make so more skilled works can see in furture


example :how u can make one dongle for nokia


here we can start from fun*****tals


from next week lesson starts

***Fundamentals in developing the software in gsm by dits ***
 

For educational purpose only

FAQ:

1. What we need first start in developing gsm software ?

Ans: You should have good patience and you should like it and you
should be aware of phones well .

2. In which languages is this softwares developing?

Ans: Most people in gsm using programming languages is c, vc++ and delphi
( so you be aware of it )

3. What u need make sure when u spend time to make sofware ?

Ans: Protection,If you make a software if you dont know how to
protect it then no point for making software either it will be free
or will be added by others

4. What all more need to know in developing this sofware ?

Ans: You should need some knowledge in ASM (assembly language )
and you should be able do some reverse engineering for this
have many tools but u should have cababilty to understand
from the tools and utilities out put .

5. What all protection methods is using now ?

Ans : There are many ways of protecting the software if we take the
existing market some use (a)server protection plus exe protection
(b) server based protection plus dongle or card
(c) server based + Mcu based interface
(d) Rsa Server + Mcu or Asic based interface + card is the best

6. Can you tell us what all stages in development ?

Ans : One reversing or spy communication, coding & Gui ,
Two communication with interface and hardware
(embedded systems) , Three server part and web support php


Will continue soon only serious people attend here

You can ask more questions as well

Dear Student
 

If you dont know any languages will be hard for this

there many institutes that teaching these languages in the world

U can learn it here the basics HERE

*** Basics 1 for programming from dits ***
 

For educational purpose only:

7. Which are common chipsets that use in mobile phone ?

Ans: TI(texas instruments ), Infeneon , Philips , ADI , MTK , Spectrum ,
New sky

8. Which are this chips platform, is there any other platform ?

Ans: There are 2 platforms ARM and MIPS but now in gsm 95% is
Arm platform


9. Which series from this company use in mobiles phones commonly?

Ans: TI- locosto , calypso ,calypso plus ,omap -DSP

*** What are common methods now people using for reversing a phone **
 

For educational purpose only :


We hope you all know what is reverse engineering
In this gsm field mostly going in this method otherwise you should need
real source either from chipset or manufacturers


Commons methods for revesing :

1. Some use to sniff the box or phone communication
( EG: Ufs supports some phones and mxkey dont have and they dont know how to develop or dont want to waste time they will try to
sniff the box if not good security its easy to sniff the
usb communications if you are good in analysing )

2. Some use to take out the flash Ic and Read full flash and analyse
the Flash contents

( You have some phone that solution dont exist so use this method
and final solution depends on programmer some make patch solutions
some make real solution )
3. Some Use datasheets and sources documents

eg: some documents regarding some cpu if u get it will be easy for
for you make solution instead of other above 2 works

4. Some use jtag and read out full dump and reverse the firmware

5. Most hard job - Analyse cpu and flash communications using jigs
with high speed analysers


next is very very hard that is much expensive solution


lets stop with here

***Are You Ready some small software for one model***
 

For Educational Purpose only :



Let start with one model example nokia one model


First you have to understand every phone have have its own sofware

some companies develop there own flasher some use default chip software


example : nokia phoenix ( owned by nokia ), chinese phones mostly use mtk orginal tools , infenoen based phone other brand like zte and all use fluid


so lets say all these softwares in market can tell is extaction from orginal
format to new format but its not easy


When make a phone first there will be 3 commuication made

1. Uart 2.Jtag 3 USB


will show u some examples of some phones soon
