View Full Version : How to modify the undongle Wlscgen VENDOR ID?

December 10th, 2007, 07:56
First of all , i want to say a big hiiiiiiiiiiiiiiiiiiiii to all members on this great forum , now let's get back to business , i'm newbie in SentinelLM protection and i need some help in changing the vendor id , i readed the wlscen tutorial of mayaputra and i'm stucking at morphid,i used the formula of his :

my vendor id xor 373E4064 =373E4FB2
373E4FB2 xor F774E470 = C04AABC2
VLM_morphid(C04AABC2) = modified patch word(his AE805C04)

HOW COULD I GET THE VLM_morphid , his example in w32dsm is from his value not mine(C04AABC2).

Another stuck it's on the zhanzixin tutorial :

8 Now we return to wlscgen.exe in our d:\mygen ,copy offset 55C8D0 16 bytes data to the undongled wlscgen.exe's corresponding position.The offset 55C8D0 may be difference,but func _computeVendorCode() refs it at the begining so we can find it easily.

9 Now we get the good wlscgen.exe, run it in ollydbg , stop at its _computeVendorCode(),we got 0xafc when it return, which proves the wlscgen is just we want.

wlscgen.exe is the original sdk and doesn't have this offset adress 0055c8d0(ida hex view : 0055C8D0: D01FE812 7346AE6B 776C6F2D AE80C3C4), in undongle version it is.
Now how could i change the vendor in undongled wlscgen.exe,completing the same values of the general register of wlscgen sdk(ida pro 5.0) .

Pls help me,i'm stucking at final and it's drive me crazy.

no one, i need help at VLM_morphId(C04AADEA) = AE805C04 , how he obtain that value , the morphid is 0043D43A , 0043D43A x (C04AADEA) = a huge number, i hate this guy , mayaputra , he didn't explain nothing.

i made it,without his formula,but i changed manualy the last 2bytes(ex. 5C04) IN ULTRAEDIT and changed my desired vendor id(checked in ida pro and it's same with original), now let's made some license.

Though, 2 patches and the wlscgen.exe works without the dongle, vendor ID and what not. Meh!

Dear TheMaster,

I am now having the same problem as you faced in the previous.

I have a software and a licnese file. (valid until next month).

By using slmdec103 , I can extract VENDOR ID from lservrc. (just 4 digit, right?)

By using slmvid2sn, I can find out serial.

By using SLMtoolkit, I can generate cracked Wlscgen.exe.

With obtained serail, I can install SentinelLM 7.2 SDK.

I know that the Wlscgen.exe from SLMtoolkit is just for fixed vendor ID.

I need to change to specific vendor ID in Wlscgen.exe.

Now I have 2 questions:

Q1: Username and password asking in Wlscgen.exe.

How can I change this to blank user name and passwors as mentioned in http://www.woodmann.com/crackz/Tutorials/Wlscgen.htm.

According to http://www.woodmann.com/crackz/Tutorials/Wlscgen.htm , the break point address are not the same with my Wlscgen.exe .

Q2: what is the corrected step to change the specific vendor ID.

Eventhough I read the articles many time, still confused.

TheMaster has not posted or signed in into the board since December last year.
Look at the dates of the posts. . .

And if you actually read the FAQ, you should know that you are supposed to do your own Searching on the Net and here for possible answers to YOUR question and then you are supposed to tell us what you have done to try to help yourself, besides post your question here.

So far you have not shown that you have tried to help yourself or done any searching for information on your topic!!!

Be kind JMI this is a friend of mine from another board, and he's trying to save me work :P) - Edinburgh, I know in the tutorial it lists a single address, the idea here is to scour the tutorial, (AND any other material you can humanly dig up), and see if you can find the corresponding spot in the file that's different. If you accomplish that then it's all downhill from there, as the work has been done for you, but in the mean time you learn a lot!

Hi SiGiNT:

To be technically correct, I was addressing my previous comments about searching specifically to zhjd.

Edinburgh, at least, showed that he had done some work on this own and had both searched, and found some information, and attempted to work out the process he was interested in, before posting.

Kayaker pointed out that the person to whom he had addressed his question was long gone from these Forums and I made no further comment about his posting.

And I'm all in favor of somebody saving you work!

Post by Edinburgh on another forum -


Please kindly be informed that now I can successfully generate the licnese by SLM SDK 7.1

There's something "vaguely" familiar about your avatar, but I just can't bring it up from deep storage.

Welll, I figured I might as well go public - I left out the numbers from the booking photo - you can guess the charges

What YOU need to do is to go actually read the FAQ.

First, we do not have a member named "Maya Putra" and you are asking for that person's help in the wrong Forum.

Second, you need to do your own research on the net on how to use "wlsgen.exe." We do not provide "step by step" instructions, especially to people who have apparently not done any of their own work.
