Greenpois0n RC5 To Have Verbose Boot & Custom Boot Logo Support


by casey on February 2, 2011

By now you might be getting fed up of these iOS 4.2.1 untethered jailbreak news but we have more updates for you. The upcoming Greenpois0n untethered iOS 4.2.1 jailbreak tool will have two more features: Verbose boot and Custom boot logo.

What is Verbose Boot & Custom boot Logo?

Let us explain if you are already not familiar with these features. Verbose boot will show everything thats happening while the device boots up.It shows a little low level information happening while booting. On the other hand, custom boot logo is what displays a graphical logo which is by default a white Apple.


The version of Greenpois0n which we are using currently uses GeoHot’s bootrom exploit. The exploit uses injection vector to apply kernel patches to get root access. In the current version Verbose and custom boot logos were not possible because the bootchain was actually not touched. Both verbose and custom bootlogos reuiore a patched iBoot which you do not have doing a userland jailbreak.

Pod2g of Chronic Dev Team has already confirmed that the Greenpois0n RC5 tool will untether jailbreak iPhone 4, 3GS, iPod touch 3G, 4G and iPad running iOS 4.2.1 OOB without any need of saved SHSH blobs for iOS 4.2b3.
