Help/Support LLDB crashes phone after setting watchpoint

[LLDB Novice 1 10 8.3.0]

Hello, I'm on a jailbroken iphone 6+ running 8.3

I'm kinda new to this whole debugging thing, but I can usually follow tutorials, and had some success with GDB/GNU in the past. (ios 6 jb)

I now have a LLDB debugger setup using putty and LLDB (windows), and I'm able to attach to a process and set a watchpoint and get the value of the variable (in this instance, it's ammo)..however, when I shoot the gun to trigger the watchpoint, the phone restarts itself.

 

I can't figure out what I'm doing wrong.  Sometimes the debugger will break at the watchpoint, but usually just crashes on the first attempt.  Are there other types of packages I need to download or remove in cydia?

Also, is GDB/GNU obsolete now?  Or is LLDB just a better debugger?

 

Thanks in advance for any help!

GDB still works great for breakpoints, I use LLB for watchpoints.

Somehow I'm unable to use GDB on iOS 8.3, any tips on getting it running?

I believe the restarts are because of the debugserver you're using.

 

Can you try the one from this topic: http://iosgods.com/topic/5380-tutorial-how-to-get-lldb-working-on-windows/

 

Set the permissions properly and remove the old one.

That's exactly the one I was using, its the only one I ever installed.

 

What do you suppose I'm doing wrong?

I'm not sure really.

 

You can try re-applying it.

 

There was a member who had the same problem you did and he fixed it by using devugserver from that post.

Ok, I just downloaded it again...

in filza, the info for the file is as follows:

Ownership: 
-Owner: mobile
-Group: mobile

 

Access permissions: 

-Mask: 06755

 

Sticky:

-Set UID: checked
-Set GID: checked

-Restricted Delete: unchecked

 

Owner: 

-Read: Checked

-Write: Checked

-Execute: Checked

 

Group: 

-Read: checked

-Write: unchecked

-Execute: checked

 

Others:

-Read:: Checked

-Write: unchecked

-Execute: Checked 

 

are those the correct permissions?

the debug server that's in my bin folder right now has the same access permissions, but the ownership is Owner: root, and group: wheel..is that incorrect?

I noticed everything else in that folder has Root/wheel as the ownership, which is why it was changed to that..should i have left it as mobile/mobile?

Try both as root/wheel and mobile/mobile

I did, tried mobile/mobile, root/wheel, and even root/staff (that's what gdb has)

 

Always crashes once I set a watchpoint and try to shoot the gun to change the value..with the original file (from that link, downloaded from PC, transferred with filza) as well as another downloaded copy from the same link (downloaded directly from/to phone)
