Quickpwn modifications

I'm looking to overwrite some particular files on the iphone during jailbreak. I think the quickpwn method is the best, as i'd like to keep all files already on the device that do not need to be modified. So i figured the easiest way was to modify one of the bundles already used in the installation process.

I unpacked the quickpwn packer and modified Data/Cydia.tar.gz to contain a couple dummy files for a test. When i use quickpwn, the process completes fine, but then the device gets stuck in a continuous reboot. My only guess is that there is some checksum somewhere that is causing issues.

so..any ideas on what might be causing this?

also, is there another tool available that uses the quickpwn method to write data to the device?

one more: can i download the quickpwn source somewhere?

i was also considering making my own ipsw adding a bundle and info.plist, then feeding it into quickpwn, but not sure if thats going to work. any thoughts?

Use PwnageTool 2.2.5 this is much earier. You can create additional bundles that users may add.
check the carrier bundle creator mentioned here. Create a bundle and check it out.

thaks volks for the quick reply. unfortuantely i dont have a mac so i cant use pwnagetool.. i was reading many of your previous posts concerning bundle creation, however none seemed to have a full description on how to do it, so im a bit lost.

ideally what i'd like to do is just be able to overwrite those files ONLY and this would have to happen in dfu mode. so i think the quickpwn/jailbreak method is what i should do.

That being said, im guessing that the bundle method is the best way to do it. So i create a ipsw with my changes, create a "\Data\PwnmetheusBundles\iPhone1,2_2.2.1_5H11-TEST.bundle" with a info.plist that matches the ipsw that i created. (this has been super helpful http://www.hackint0sh.org/forum/f146/40063-4.htm).

So am i approaching this correctly? is there an easier way? from what i read i think your carrier bundles are meant to be used either after jailbreak, or during jailbreak where all data is deleted. this method wont work right for me because 1. the data is inaccessible after jailbreak, and 2. the data is destroyed when using options other than quickpwn (remember, only on windows).

i am trying to get a mac shipped to me tomorrow, but its kinda of up in the air as to when it will actually be delivered so i want to try not to rely on that.

I have been playing with bundles for Windows versions a while ago for my carrier bundle creator. For Quickpwn (and Winpwn before) the packages need to be tar archives. Thats not a problem at all of cause. The problem is that owner:group and permissions for each containg file has to be set.
I my case, that had to be done by the webserver, it is not that trivial, but I could manage it.
If you're doing it on your Windows box, you have to make sure they are placed with root:wheel and the propper permissions (755 in most cases).
You have to apply this while using the tar command (while packing). I know how to do this on Mac-OS X (cause it is Unix) and on Linux but I do fail on Windows.
I am more or less a regular user on Windows, sorry.

one more to be added: I know that PwnageTool is made to accept custom bundles, I do know Winpwn was aswell. But I have never looked into Quickpwn how-to get this done.

As Steve would say: One more thing!

to give you a jump-start on how-to get this working on a Mac, check these old threads:

so yup, permissions where the problem. i solved it by

From iphone:

Code:

tar -pcvf Pack.tar /path/to/file/to/copy

copy that from the system via scp

extract quickpwn:

Within Windows, double click the quickpwn.exe once it loads goto
start:run type %TEMP%

copy all data out of the RarSFX1 folder into another folder

Then copy the Data/Cydia.tar.gz and the Pack.tar to a Linux system

From a Linux system (as root):

Code:

mkdir iphone cd iphone tar -pzxvf Cydia.tar.gz tar -pxvf Pack.tar rm Cydia.tar.gz rm Pack.tar tar -pcvf Cydia.tar . gzip Cydia.tar

Copy the new Cydia.tar.gz off the linux system into the Data/ directory

Now my new problem is that quickpwn is too smart. because the phone i want to jailbreak is locked with a passcode, it wont register with quickpwn in the locked state. So i was able to fool quickpwn up to a certain extent by:

1. Put target phone in DFU mode
2. connecting another iphone
3. clicking next in quickpwn up until the "ready to pwn" screen which gives you the DFU instructions
4. when it reaches "Release the Power button and continue to hold Home for 30 seconds", quickly connect the target phone which is in DFU mode already.

unfortunately, this only works up the "uploading exploit bootloader" step.

So is there an app or a copy of quickpwn or any way to write when the device is already in dfu mode, rather then going through all of these semantics?

also the reason i cant use pwnagetool is that it completely reflashes all data on the device. i need to update on the files the need to be updated, and leave the rest alone, as quickpwn does.

I was playing with this a while back (doing something else).

At that point, try removing the cable and plug it back in.

no luck with that, progress bar flashed, but still stuck on uploading exploit
