Thread: [602] Struggle deobbing and decompiling client (wtf?)

Hey guys,

I've been trying to make a 602 deob using various tools like RSGD and AlterRS but I just can't seem to get it working... The deobbers work but when I decompile the classes I get weird code with labels and breaks and it's not compilable. All downloadable deobs on here don't have those weird statements. What am I doing wrong?! I've tried JODE, Fernflower, CFR decompilers, I tried playing around with transformers, even tried other deobfuscators from Github ([Only registered and activated users can see links. ]). Tf am I doing wrong? I'm frustrating and feel like people on here are like super human beings that pull deobs out of their sleeves lmao and I can't get this fucking shit to work.


Example code (602 login class):

Code:

                     label499: {
                        Class44_Sub1.aClass88_3936.method680(0, aClass44_Sub15_Sub2_4126.aByteArray4316, var0 + -75, 8);
                        aClass44_Sub15_Sub2_4126.anInt4325 = 0;
                        Class37.aLong605 = aClass44_Sub15_Sub2_4126.method1883(true);
                        Class44_Sub15 var27 = new Class44_Sub15(70);
                        var6 = new int[]{(int)(9.9999999E7D * Math.random()), (int)(9.9999999E7D * Math.random()), (int)(Class37.aLong605 >> 32), (int)Class37.aLong605};
                        var27.method1913(10, (byte)97);
                        var27.method1880((byte)-65, var6[0]);
                        var27.method1880((byte)-65, var6[1]);
                        var27.method1880((byte)-65, var6[2]);
                        var27.method1880((byte)-65, var6[3]);
                        var27.method1917(Class51.method382(var0 ^ -68, Class44_Sub39_Sub32.aString7249), (byte)-125);
                        var27.method1875(Class228.aString3275, (byte)-14);
                        var27.method1919(Class44_Sub17_Sub13.aBigInteger7178, Class44_Sub41.aBigInteger5978, 65);
                        var26 = Class169.aClass44_Sub15_Sub2_2676;
                        var26.anInt4325 = 0;
                        if (~Class103_Sub1.anInt4811 != -3 && ~Class103_Sub1.anInt4811 != -4) {
                           var26.method1913(Class44_Sub30.aClass207_5089.anInt3072, (byte)105);
                           var26.method1896(0, true);
                           var7 = var26.anInt4325;
                           var26.method1880((byte)-65, 602);
                           var26.method1913(Class194_Sub3_Sub2.aClass195_6857.anInt2958, (byte)112);
                           var26.method1913(Class44_Sub2.anInt4029, (byte)126);
                           Class36.method283(var26, (byte)-107);
                           var26.method1875(Class265.aString3800, (byte)-14);
                           var26.method1880((byte)-65, Class44_Sub17_Sub4_Sub1.anInt7738);
                           Class194_Sub4_Sub3.method2886(var0 ^ -51);
                           var26.method1887(var27.anInt4325, (byte)76, 0, var27.aByteArray4316);
                           var26.method1914(-var7 + var26.anInt4325, 2);
                           if (!var1) {
                              break label499;
                           }
                        }

                        label450: {
                           if (Class219.anInt3180 == 12) {
                              var26.method1913(Class44_Sub30.aClass207_5088.anInt3072, (byte)83);
                              if (!var1) {
                                 break label450;
                              }
                           }

                           var26.method1913(Class44_Sub30.aClass207_5086.anInt3072, (byte)91);
                        }

Is that control flow obfuscation? It's definitely not in the right order (trying to do 602 lobby login).


I'd appreciate any help or any pointings in the correct direction...
