Xcode 4.2: Error 0xC002 when trying to use a jailbroken iPhone 3G for development

Question

I have this jailbroken iPhone 3G with iOS version 4.2.1 (the latest supported version). When I connect it to Xcode 4.2, Xcode starts copying the debug symbols. It stops copy

Answer 1

I fixed this bug in![enter image description here][1] this way:

I duplicate the 5.1.1(9B206), rename it to 5.1.1(9A405)[my ios device is this version], then the error is gone.

Answer 2

The answer above (https://stackoverflow.com/a/9944892/1390251) works, basically, but for newer versions of Xcode you probably need to rename the files as follows, having them end with '7' instead of '6':

touch .copied_dyld_shared_cache_armv7
touch .processed_dyld_shared_cache_armv7
touch dyld_shared_cache_armv7

If not sure, you can keep both sets of files (...6 and ...7) in the relevant folder (can also be 5.1.1 for that matter) and it should work. (have tested it on iPhone 4 with iOS v5.1.1 genuine)

Answer 3

Error in Xcode getting debugging info from 5.0.1 iphone solved, see the link to archive with iOS5.0.1 debug info download & unpack to "~/Library/Developer/xCode/iOS DeviceSupport/" & be happy =)

Answer 4

Alright, after a lot of testing and digging up the filesystem... I solved it. It turns out that there are just a few files that are not downloaded from the device (for reasons still unknown). They are related to the dyld cache (don't really know what this is and what it's for). Here are the steps to make your 4.2.1 device debuggable in XCode 4.2 and 4.3.x:

1. Close Xcode
2. Go to: ~/Library/Developer/Xcode/iOS DeviceSupport/4.2.1 (8C148)/Symbols/System/Library/Caches/com.apple.dyld/
   Note: if you don't have this folder, run Xcode, connect your device, and wait until the error 0xC002 appears in Organizer - the folder should be created by that time.
3. Create 3 empty files there called:
   • .copied_dyld_shared_cache_armv6
   • .processed_dyld_shared_cache_armv6
   • dyld_shared_cache_armv6
4. Run Xcode and enjoy the light next to your device eventually go green:)

Or, for the terminal lovers:

cd ~/Library/Developer/Xcode/iOS\ DeviceSupport/4.2.1\ \(8C148\)/Symbols/System/Library/Caches/com.apple.dyld/
touch .copied_dyld_shared_cache_armv6
touch .processed_dyld_shared_cache_armv6
touch dyld_shared_cache_armv6

This is obviously a hack but it works perfectly for debugging and I haven't noticed any side-effects so far.
Enjoy!

Small update:
I tested it on my snow leopard hackintosh, with the Xcode 4.2 (most recent to date) and although the device is active in the organizer and it is possible to run the app on the device, i get black screen on launch. It gets installed but apparently debugger cannot get attached. I had the same problem with 4.0.2, when the 0xC002 problem didn't yet occur so I think it's unrelated and might even not happen to others. Nevertheless, 0xC002 is still solved.
On my main development machine with Lion and Xcode 4.3.2, device is perfectly debuggable.

Answer 5

It seems that you cannot debug apps on iOS 4.2.1. I tried several restores to iOS 4.2.1 with same effect. Downgrading to iOS 4.0 was the only thing that worked.

The reason for whole problem is that iOS 4.2.1 is not supported in XCode, according to this website.
