Getting into the Blackberry 8700v - GSM-Forum

AHeisenberg · 02-03-2007, 12:27

I have a blackberry 8700v from Vodafone UK that's locked. I've allready found a site which can unlock it for 30 pond. But I would like to have it unlocked for free.

As I have been looking around on the internet there isn't yet a way to unlock it. Therefore I would like to try finding a way myself. Isn't it possible to reverse engineer the software of the blackberry? If so, where do I start?

You can start by paying those 30 pounds instead trying do something obviously have no ideea about.

I agree with Hacker.

you gonna spend a lot of time that cost more 30 pounds.

Good Luck...

It's something I would like to learn. Next semester I'm going to have to learn assembly. Later on I will have to learn how devices like a blackberry are programmed. So why wouldn't I start now with unlocking this blackberry?

next semester you begin ASM? well next semester you will find out how hard this will be

in your one college year you will learn < 10% of knowledge needed for reversing any consumer electronic product (i have been there mate).

to start you, you will need the flash file for your phone, or some way to read flash from the device, and a disassembler for the targets CPU type (usually IDA interactive pro disassembler).

there may be an exploit in the phones e2p comunications protocol, so search for documents on that.

you may be able to read, edit and write an eeprom zone. so look for info on that.

see there is many ways, not just one method.

if it was as easy as following a flow chart for everyone who wants to try, then every one would be making unlock boxes!

well, i better give you some advice not going to deep to the wrong end.

start with lpc2106 development board, er........ oO since next semester you just start asm, i guess avr will be a good start or PIC microcontroller.

And just study them well. study them hard. If you are gifted one then you'll soon be a reverse engineer.

Good Luck...

Thanks. I will probably get nowhere but at least I will have learned something more than if I would have bought the unlock code. In the end, learning is the most important thing.
