It may happen with some Android games (and not only) that you see an error like this when trying to hack or simply browse a dll.

When this does happen, it means there's a missing or corrupt metadata version in the dll headers.

I'll be fast and simple. What we will do is replacing these headers using CFF Explorer and HxD (or your favourite HEX EDITOR.. even CFF Explorer if you do prefer) with some working metadata version headers.

If you don't have CFF Explorer installed yet, you can download it from here: CFF Explorer

Now, let's open CFF Explorer and move the affected dll into the left box:

Then, click on .NET Directory and a sub menu will appear. Just select MetaData Header and a table will show at the right.
What you need to do is to copy the offset relative to the VersionString which represent the Version of the Metadata:


As you can see, my Offset for the VersionString is: 00012118. I'll copy this offset.

Now, let's use the Address Converter in CFF Explorer,…

How to get the decrypted DLL , through IDA , GDB or directly decryption. A new gaming platform out of the game (game name omitted), try ida dump the decrypted DLL , (the previous method introduced, as dynamic debugging, you can find information on the Internet) What happen if you load DLL into Reflector, Invalid 'BSJB' Signature in the Metadata header. This error, that is, BSJB this structure there is an error, I do not know .net file header structure, specifically refer to the article, in recent days, will focus on learning under the net file header structure. http://www.cnblogs.com/dwlsxj/p/PE.html

Hello dear community,
Today, i will teach you how to mod x86 libs. x86 is not that hard to understand because the instruction are almost the same as ARM. In this tutorial, i mod the game called The Sandbox 2.
You don't really need to mod x86 at all since I never heard any problem with ARM translating to x86, and it's too hard to change instruction without code caving. Just wanna make tutorial lol
Now let's start modding.
In this tutorial, I'll show you how to mod The Sandbox Evolution very easy in x86.
First of all, you need IDA PRO and Hex Workshop installed on your computer. If you already have them installed, go to next step
Open the APK file with WinRar and extract the lib folder (In case you want to mod both x86 and ARM) Open the x86 .so file in IDA. You will see the dialog box similar to the following:

In x86, you don't need to change anything. MetaPC is fine. Click OK to disassemble the lib file, and let it fully load. After that, press CTRL + F,  search "isEle…
