Redsn0w Jailbreak Stuck at Uploading Ramdisk iPhone 4 4.2.1

I was trying to jailbreak my iPhone 4 firmware 4.2.1 with latest version of Redns0w but it keeps getting stuck at "Uploading Ramdisk" stage. After that I get an error that Redns0w is not working properly and will shutdown.

Please help me to resolve this issue, so I could JB my iPhone 4 on iOS 4.2.1?
Question asked by Jhon

MuscleNerd, iPhone Dev-Team member has practically responded to your question. He has confirmed that untethered iOS 4.2.1 jailbreak is around the corner, moreover, the next version of Redsn0w will take care of Ramdisk issue. Updated Redns0w will be capable of handling much bigger files than 25MB Ramdisk limit, so no crucial data and tweeks installed from Cydia would be lost. Last but not the least, it should not require a complete restore for those who already have done tethered jailbreak, just another redsn0w run will be required to enjoy the untethered jailbreak.

Coming back to your query regrading Ramdisk, here are few possible solutions:

1. If you are on Windows XP, try running running in compatibility mode, it may resolve the issue. Moreover, you should run the software with an administrative account or rights.

2. Set Redsn0w process affinity to CPU1.
a. Go to task manager (CTRL+ALT+DEL).
b. Right click redsn0w.exe process and set process affinity to CPU1 only.
