Okay, it took me some trying and stuff but I finally found a way!
Okay, this is going to be simple step-by-step
First: Copy this to the root of your SD card: http://forum.xda-developers.com/atta...7&d=1300751790
Second: Go into HBOOT and click yes when it asks you to update (note: Please make sure your SD card is FAT32 and not FAT, it must be FAT32 for this step to work.
Third: Remove the img file from your SD card and add this file: http://downloads.noshufou.netdna-cdn...arm-signed.zip
Fourth: Go into HBOOT and click Recovery!
Fifth: Click install zip from sdcard (or some thing like that) (Protip: Navigate in the recovery with the trackpad, not the power button!)
Sixth: Click choose zip from sdcard
Seventh Locate your zip and let it update.
AND YOU'RE DONE!
Have fun being free!
If you're having problems with the HBOOT not detecting the .zip update, please check if you SD card is FAT32.
