wings are the devil

version heading appears like this when I run GDB: GNU gdb 6.3.50-20050815 (Apple version gdb-1708 + reverse.put.as patches v0.4) (Mon Apr 16 00:53:47 UTC 2012)

iPhone 5S ios 9.3.3 Win 7 I have not been able to get either GDB or LLDB/debugserver working with 9.3.3 What are some other methods or tools to determine the IDA offset location from the GamePlayer memory location? -M

Thanks

Nope that doesn't do it. What I'm looking for is something that will trigger a breakpoint or watchpoint when register $r0 is equal to a certain value. -M

In GDB I was able to put a conditional watchpoint on a register: watch $r0 == 0x01234567 Is there an equivalent for LLDB ? -M

I was able to setup LLDB in Win7 however I'm still being returned all my debugging information in relation to _mh_execute_header () Let me be perfectly clear -- I was able to debug perfectly fine using GDB on iOS 8.4 through a Win7 machine as of Nov 19 2015 <sample output from Nov 19 2015 07:20 PM> 0x00677150 in m_QuestSummary_GetPercentCompelete () 6: $r4 = 354180160 5: $r3 = 1110881504 4: $r2 = 84215400 3: $r1 = 16 2: $r0 = 1 1: x/i $pc 0x677150: 00 00 50 e3 cmp r0, #0 ; 0x0 However by 12 December 2015 all my debugging started to look like this 0x001f000c in _mh_execute_header () 4: $r2 = 2041261 3: $r1 = 1 2: $r0 = 19582444 1: x/i $pc 0x1f000c: 78 44 00 68 stmdavs r0, {r3, r4, r5, r6, r10, lr} <snip> 0x000a3b38 <_mh_execute_header+248632>: 00 68 90 f8 undefined instruction 0xf8906800 0x000a3b3c <_mh_execute_header+248636>: ad 10 11 f0 undefined instruction 0xf01110ad 0x000a3b40 <_mh_execute_header+248640>: 01 0f 05 d0 andle r0, r5, r1, lsl #30 0x000a3b44 <_mh_execute_header+248644>: 01 6e 19 b9 ldmdblt r9, {r0, r9, r10, r11, sp, lr} 0x000a3b48 <_mh_execute_header+248648>: 03 21 08 91 tstls r8, r3, lsl #2 0x000a3b4c <_mh_execute_header+248652>: 6a f3 bc d2 adcsle pc, r12, #-1476395007 ; 0xa8000001 0x000a3b50 <_mh_execute_header+248656>: 02 98 00 f1 undefined instruction 0xf1009802 </snip> At first I believed that this was due to some patch of my Taig iOS 8.4 Jailbreak. So I used Cydia Impactor and restored my phone to a clean jailbreak state. After reinstalling GDB and a few other bare bones tools I got the same results -- only _mh_execute_header () returns. I have been racking my brain and so I figured it had to do with the interface between the iOS and my Win7 debugging machine. If this is not the case I'm completely at a loss. Can anyone confirm if they are able to use iOS8.4 with either GDB or LLDB and NOT get all returns in relation to _mh_execute_header () ? If so please post a code snippet of any available iStore app along with version etc. I would like to compare my output to a known sample. Thank You, -M

I've been discouraged by the issues surrounding iOS 8.4 and debugging on a Win7 machine. I've looked into making an OSX VM on my Win7 box and am guessing I'll encounter different issues that will still prevent me from using it properly. What would be the cheapest used mac machine I could buy that would still do a great job as a debugger? What version of OS X needs to be supported ? What are some min recommended specs for such a box? Thanks -M

Thanks ITz_kser ! I was able to get the LLDB debugserver running and I'm trying out the various commands. Woo! -M

I'm still using Win7. But GDB worked perfectly fine 2 months ago with my same Windows PC setup at that time. ( there have been a couple of monthly updates since then ... ). I downgraded the GNU Debugger install from cydia.radare.org back to version 1518-12 hoping that would fix it ... but now I get the "Illegal instruction: 4" error. It's very frustrating as I was able to use this in October and now it doesn't work @ITz_kser I would love to use LLDB however I have not been able to figure out how to use it with a Windows PC. Can you point me to a correct setup instruction? -M
