EDIT: No need to rename it now, just download and put on sdcard.
Edited because some people could not get it to work because renaming it was the hardest thing in the world :banghead:
All credits to Madmaxx for this great recovery....
Download PB99IMG.zip and put it on the root of ur sdcard (not in a folder) and then with ur phone off hold volume down + power. ur bootloader will look for the PB99IMG then ask u if u want to update recovery, volume up for YES, it will then ask you to reboot device, volume down for NO. Once its finished u now have 4ext recovery and just use volume buttons to navigate to recovery then press power button to enter recovery. I have tried it myself and it works, its the exact same method to install as Alpharev's hboots via PB99IMG.
Dont forget u must be S-OFF lol
Dont forget to delete it off sdcard once ur done or u will get asked to update everytime u enter bootloader

(Also u can extract the PB99IMG.zip file and flash recovery.img via fastboot commands or android flasher)
