Problems with IDA Pro
Hi ppl !
Hope anyone can help me.
I´ve some problems by using IDA Pro to crack apps for Nokia 3650 / 7650.
No panic, I´m no beginner in asm and cracking, but I´ve never used IDA Pro before.
I´m using IDA Pro V4.15 , but also have IDA Pro V4.30.
Okay, I already got two tutos for cracking s60 software from atzplzw (18plus2) and Phantasm. (Great work guys!)
I read them again and again but there´s nothing that would fix my problems.
In the tutos they are using IDA Pro 4.04, so perhaps that could already be the main problem?
But let me explain what are these problems I have :
For testing I took the .app from Stacker V3.0
Opened it with a hexeditor and looked for the offset of the "" message.
Okay, found it on 0000BCA6.
Closed the hexeditor and opened IDA Pro.
Selected Stacker.app and marked "Load resources" in the following window.

After click on "ok" IDA began to read the file.
But if you look in the status window you see that there appear many errors while loading the .app.

Okay, set Options => General => Auto comments ON and browsed to offset 1000BCA6, but somehow the message isn´t there. But hey, after browsing a little bit higher I found the text on offset 1000BC2C.

Hmm... what happend ?
Okay, never mind. I found the text.
Right-click on "0x6E0055" and selecting "undefine" from contextmenu and I could read the message.

Now I jumped to XREF 10008664 and landed here...

Alright, up to this point all like discribed in the tutos. But there´s no second XREF jump at this position. Well, if there isn´t anymore XREF, I guess I AM already in the code.
But after switching into code-view, it looks like this...

Sorry, but I don´t anderstand this. 
Anything I did was wrong.
Does anyone of you know what I have to do? Perhaps atzplzw or Phantasm?
Sorry to ask such stupid questions.
Many thanx in advance !
Regards
Leon
