How to unlock at89s52

Hi,

I want to unlock one of my at89s52 as unfortunately I have lost my code. I had made all three lock bits LB1,LB2Lb3 programmed due to security concern.
Can anybody tell me how can I retrieve the binary out of it.

Thanks in advance.

Forget about it and don't waste your time ..
If you know how it suppose to work - write the code from the beginning ..
And don't trust charlatans who claim that they can read the code ..

Is it illegal to retrieve your own code ?

It may Your's or Not. It may also be an attempt to open one of my chips containing my code. Who is gonna prove and what? But if you are the real author and the owner, it is your duty to keep a backup of all your work. Anyways..Yes..it is illeagal to open your own code coz once locked, no one can prove its yours or mine.

Would you send your money up front before they give you the code?
I would NEVER trust a company that operates like that.

You can learn how to do it yourself, or even easier, (and faster) just re-write the code since it is yours to begin with, you should have the knowledge on how to do it.

Technically, it is ILLEGAL, however if you are a very large corporation with endless amounts of $$$$ and you can afford the highest payed lawyers, YOU CAN DO WHATEVER YOU WANT, reverse engineering small companies products is nothing new. All the large company would do is use their power to run the small company's legal bill through the roof, therefore bankrupting the small company.
