前段時間有人玩知名ERP，玩的很嗨，促使大家都學習了一下；

軟件名：GJ ERP（無殼）
軟件版本：T9 Top v20.5
破解方法：爆破（非模擬狗）
所需工具：OD吾愛版

以上所需東西都需要自己網上找

教程開始：

1.思路：破解一款軟件，首先你要了解這個軟件有哪些限制？它是通過什么方法實現的？你要如何處理？當你有了這些思路才能把它辦掉。
2.開整：
2.1軟件打開會提示你服務器端沒找到加密狗，所以我們要把服務器端加密狗類型改成軟狗，所謂軟狗就相當于是個注冊碼，不需要你插硬件狗就行。做完這一步就是開始搞客戶端了。
2.2.1斷點返回法，先讓軟件跑起來彈出注冊框后隨便輸入一串碼后反回OD暫停，一路執行到返回（Ctrl+F9）直到可以點軟件的“確定”按鈕后再一路執行到返回（Ctrl+F9）直到返回程序領空。看是從哪個call中出來的，出來后到哪里做了判斷（判斷是否真碼）……
2.2.2 簡單的方法是有提示“綁定失敗，請稍后重試。”，直接搜這個也行，上面的方法可以不用了，如果你用了說明你看完教程就上了，哈哈~~
直接上代碼：

005CBC90 . /EB 3E jmp short GraspStd.005CBCD0 ；注冊狗關鍵跳，我是jnz改的jmp
005CBC92 . |8D45 D0 lea eax,dword ptr ss:[ebp-0x30]
005CBC95 . |8B55 FC mov edx,dword ptr ss:[ebp-0x4]
005CBC98 . |E8 2357E3FF call <jmp.&rtl150.System::UStrFromWStr>
005CBC9D . |8B45 D0 mov eax,dword ptr ss:[ebp-0x30]
005CBCA0 . |33D2 xor edx,edx ; GraspStd.<ModuleEntryPoint>
005CBCA2 . |E8 3165E3FF call <jmp.&rtl150.Sysutils::SameText>
005CBCA7 . |84C0 test al,al
005CBCA9 . |74 0D je short GraspStd.005CBCB8
005CBCAB . |8D45 FC lea eax,dword ptr ss:[ebp-0x4]
005CBCAE . |BA 9CBE5C00 mov edx,GraspStd.005CBE9C ; 綁定失敗，請稍后重試。
005CBCB3 . |E8 D855E3FF call <jmp.&rtl150.System::WStrLAsg>
005CBCB8 > |8D45 CC lea eax,dword ptr ss:[ebp-0x34]
005CBCBB . |8B55 FC mov edx,dword ptr ss:[ebp-0x4]
005CBCBE . |E8 FD56E3FF call <jmp.&rtl150.System::UStrFromWStr>
005CBCC3 . |8B45 CC mov eax,dword ptr ss:[ebp-0x34]
005CBCC6 . |E8 5D95E3FF call <jmp.&GraspCMRunStd.Udllmessageintf>
005CBCCB . |E9 A6000000 jmp GraspStd.005CBD76
005CBCD0 > \A1 94496F00 mov eax,dword ptr ds:[0x6F4994]

2.2.3上面的也可以跳過，就是檢測加密狗的時候跳，就不會彈注冊框了
可以直接搜軟件啟動時彈出的 “正在檢測加密狗，請稍候...”字符串找到地址（方法看注解）：

006A7FD4 . BA 38856A00 mov edx,GraspStd.006A8538 ; 正在檢測加密狗，請稍候...

至此軟件已基本能夠使用了，但使用插件時仍會提示未注冊不能使用插件
3.于是我們找“----未注冊”如果不知道可以在所有未注冊上下斷，我這里直接上關鍵代碼：
