Any idea about ZTE SP Calculation from ESN/MEID? - GSM-Forum

[Shadab_M] · 02-23-2012, 09:33

Hi!

Can anyone help me with ZTE SP ALGO used to unprotect phone.

We cant send phone to Download mode, or write any NV Item without first sending it. Its is based on ESN/MEID.

AFAIK, there are three types of code calculaton, 2 are 6 digit decimal and one is 6 byte HEX.

Someone already gave me clue, but i am not so good in reversing

Any help will be appreciated.

Yes Bro! I know it.

But my current condition does not allow me to pay a big $$$.

A nice person gave me some hint, but I am not so experienced with Olly or IDA so still unable to figure out.

Lets see what happens.

Learn Delphi if you want to be a serious programmer.

Once you will start with VB or .NET, and will develop a good tool, then you will have no time to learn Delphi or rewrite codes in it.

So better start with the thing, which will be suitable for future too.
