Here is the Recovery File:

For those who dont know what this is, it is the eboot that recover the CFW back to 1.50 and it is also used to recover for semi-brick. (This thing was created before the Pandora, and I am not sure if it works on the slim because i dont have one)

yeah it is still useful because you dont need the battery but pandora does load fw higher than 1.5 and that saves alot of steps.
