version4.1 model mc jailbreak greenpois0n rc5 loader is not opening
On the iPod touch 1g and 2g with iOS 4.1 and 4.2.1, there have been many times where Greenpois0n has failed to jailbreak and resulted in an iBrick (the famous expensive paperweight). And, when it actually does work, Loader refuses to open or download Cydia. When this happens, the device becomes extremely slow, so slow that you can even make it go to sleep easily. These problems are usually caused be an overload in your iPod's data. To fix this, I would recommend that you either clear up your device's memory or restore it, so you have a clean space for the jailbreak. Also, although I'm not a big fan of this, you could also try to rejailbreak it with Black ra1n. Not sure it'll work though.
