Tutorial [Working on iOS 9] How to get LLDB Working on Windows!

Rook · October 26, 2017

This tutorial may still work, but using the native lldb for iOS is suggested:

This tutorial was originally made by caoyin and I got his permission to post it here.

What is lldb?
LLDB is a next generation, high-performance debugger. It is built as a set of reusable components which highly leverage existing libraries in the larger LLVM Project, such as the Clang expression parser and LLVM disassembler.

Homepage: http://lldb.llvm.org/

LLDB on Mac OSX Tutorial: http://iosgods.com/topic/5391-tutorial-memory-debugging-with-lldb-on-mac-osx/

Requirements:
- Jailbreak
- OpenSSH from Cydia
- PuTTY or iFunBox or any other Terminal clients.
- LLDB.rar: https://www.dropbox.com/s/cvr0kf3jt6yraem/LLDB.rar
- debugserver: https://www.dropbox.com/s/501sg030hhpiuxi/debugserver?dl=0

Instructions:
Step 1: Download debugserver from the link above and using iFile, place it in /usr/bin/ then set permissions to 6755.

Step 2: Connect you iDevice to your computer via USB cable.

Step 3: Download and unzip LLDB.rar and rub lldb.cmd.

Update: itunnel_mux.exe does not seem to be working on Windows 10 as it seems. It is suggested you use iFunBox's Quick Toolbox option to create a new USB Tunnel on port 23.

Step 4: Open PuTTY or iFunBox and type in this command:

debugserver 127.0.0.1:23 --attach=PID or BINARYNAME

PID is the Process ID of the app and Binary Name is the Binary Name of the app. You can get PID & Binary Name from iGameGuardian or Binary Name from iFile/Filza.

Note: The app needs to be running on your iDevice in order for lldb to attach.

Example:

PID:

debugserver 127.0.0.1:23 --attach=28437

Binary Name:

debugserver 127.0.0.1:23 --attach=Asphalt8

Replace 127.0.0.1 with your PC IP if you can't connect.

debugserver is now waiting for the connection request from lldb.exe

Step 5: Switch to the lldb window and type in the command below and press enter:

process connect connect://127.0.0.1:23

Replace 127.0.0.1 with your device IP if you can't connect.

Step 6: Press CTRL + C to interrupt the process and type C to continue.

That's it!

Some popular lldb commands compared with gdb:
http://lldb.llvm.org/lldb-gdb.html

GDB LLDB
i r $pc register read $pc or reg re $pc
break *0xaddress b s -a 0xaddress
watch 0xaddress w s e -- 0xaddress
x/dw 0x111 x/dw 0x111 or memory read -s 4 0x1111 or mem re -s 4 0x1111 4 means 4 byte & -s = size
x/i 0x11111 ?x/i 0x11111
set *0x1111=0x11111 memory write -s 4 0x1111 0x1111 or mem wr -s 0x1111 0x1111
set $r1=0x1 register write $r1 0x1

What's in your hosts file (Windows/system32/drivers/etc/hosts)?

Have you also tried this on another app to see if it's only x process?

Here is HOSTAGE FILE....

# Copyright © 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host

# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
127.0.0.1 licensing.ultraedit.com
127.0.0.1 licensing2.ultraedit.com
