Use kloader to bootstrap patched iBSS/iBEC on A4+ devices
Has anyone tried loading patched iBSS/iBEC on A4+ device ? That way we would be able to load unsigned ramdisk (which could be used to decrypt kbag even on non-limerain devices).
 * It won't work as the AES engine gets disabled when the kernel is booting up. Jumping back into iBoot won't reenable it. --Aker 21:56, 12 September 2014 (GMT+1)
 * Does it make a "call" to coprocessor so that it is disabled on hardware level ? (Are there any details available on how this is done ?). --Danzatt (talk) 21:32, 12 September 2014 (UTC)
 * The IOAESAccelerator chip gets a request to restrict the access to the GID key and disables it until the iPhone/iPad/iPod touch is rebooted. -- Aker 08:54, 13 September 2014 (GMT+1)
 * Yes, I know that. But I thought bootloader just hides it from the kernel. Is there any source that confirms it is disabled per-reboot ? (Also... How was it possible that XPwn's kernel patcher could patch kernel to grant access to GID key ?) --Danzatt (talk) 10:59, 14 September 2014 (UTC)
 * Well, you're right  --Danzatt (talk) 11:14, 14 September 2014 (UTC)

Greenpois0n Method
After GP does its magic and the device boots into the patched iBSS, I cannot get the command to decrypt the KBAG to work. In iRecovery, 'go aes dec [long KBAG string]' gives no output. Commands like bgcolor, reboot, etc. work, but I cannot get any feedback from the device to give me the decrypted KBAG. Has anyone gotten this to work? --Cool name 16:01, 11 November 2010 (UTC)
 * you need a payload or run -s flag on IBSS --liamchat 16:29, 11 November 2010 (UTC)
 * I'm pretty sure the payload is already initialized by running GP, because when opening the iRecovery console with 'sudo ./irecovery -s' it spits out stuff about Greenpois0n initializing, aes_crypto_cmd being patched, etc, and it is an iBSS. My trouble is getting the device to respond to the go aes dec command, I think it may be a problem with iRecovery but not sure --Cool name 17:03, 11 November 2010 (UTC)
 * well what copy of IRecovery do you have i know that the one from User:GreySyntax works also try an IRecovery script like --liamchat 17:43, 11 November 2010 (UTC)

Project
So I'm working on a project for the AES Engine, May I add the info somewhere in this page? AESPayload Syringe --Haifisch 22:38, 13 November 2012 (MST)
 * No. Finish your project and ask again. If it's really useful and used by more than 1000 users, we might add it. --http 05:22, 14 November 2012 (MST)
 * Finished --Haifisch 00:03, 17 November 2012 (MST)
 * Mind explaining exactly how one would use it? --5urd 14:39, 17 November 2012 (MST)
 * New people to the hacking community (iOS hackers) may want to help by finding the keys to such things as kernelcaches and root fs dmgs. Using this tool they can, this may be the easiest way to find it, It does most of the work for you. All one would need to do is get the KBAG key and run the aes decrypt command with the included irecovery tool (Not of my work). I suggest this as a starting point for the new guys jumping into hardware hacking. --Haifisch 16:39, 17 November 2012 (MST)

Finding AES keys.
How can I find the AES keys? I have Haifisch's version but I cant find out to compile. Also I dont get irecovery to work. --iAdam1n (talk) 18:07, 14 November 2012 GMT}}
 * Not being rude, but if you can't compile a simple Makefile project, you need to learn a bit more before delving into things like hacking the device's hardware and software. --5urd 16:34, 14 November 2012 (MST)
 * I made my version as easy as possible (without just handing him a compiled executable). I want him to learn at least to compile a simple project. --Haifisch 19:14, 14 November 2012 (MST)
 * Did you make it for Mac? Also I cannot get the irecovery -s to work. --iAdam1n (talk) 23:20, 15 November 2012 (GMT)
 * What happens if you run ? Is it a Mac Intel executable? If not, that's why. Any yes, it is for Mac. You need   and   though. --5urd 17:45, 15 November 2012 (MST)
 * How do I use the pwnstrap for iOS 6.x? cant use pwnagetool to cook. haifisch what about instructions for your tool? --iAdam1n (talk) 18:13 2 December 2012 (MST)
 * You make me sad... pwnstap is just (really) uploading the custom iBSS file; You cannot simply compile my tool yourself so why not learn how to like we all did? --Haifisch 00:34, 2 December 2012 (MST)
 * I can but half of the commands don't work. --iAdam1n (talk) 5:46, 2 December 2012 (MST)
 * Because you need to set them up and know how to use them --Haifisch 15:46, 2 December 2012 (MST)

 * How would one find these for S5L8900? The greenpois0n method would obviously not work since it did not support S5L8900. --iAdam1n (talk) 16:48, 14 October 2014 (UTC)
