I see a real problem with the iPhone hacking community. Most of the knowledge about the iPhone is somewhere within the dev team

The 3G bootloader is sig checked by the bootrom. So even removing the NOR and patching the bootloader(to remove main fw sig checks) and main firmware doesn’t work for an unlock. Big thanks to TA_Mobile for dumping the NOR and confirming this.

Congrats to the dev team for finding the ultimate exploit in the S5L. We may not agree on many things, but I certainly respect your skills.

In the KBAG section of the img3 files, you’ll find 0×20 bytes after the section header. De crypt them with the hardware AES engine and get IV: 29681F625D1F61271EC3116601B8BCDE KEY: 850AFC271132D15AE6989565567E65BF (this is the 2.0 ramdisk)

So I read this on gizmodo. Here’s the truth… Post beta 4, the ramdisk hack stopped working.
