Last I seen, it's not possible to install 1.5 firmware on Slims UNLESS you use Time Machine. (Might be new ways now, I dunno.)
You can use your battery that is Pandorized as a normal battery. 2 ways:
1 - Use Booster's Multi-IPL Bootloader. In simple terms, it will have your PSP boot normally as if the battery was normal. You install the program on your memory stick and it's like a 22 kb file. I use it myself and works wonderfully. (I cut the pin.)
2 - WHILE you were or are cutting the pin on the battery's motherboard, instead of cutting the pin, cut the gold/copper line that is near the number "19" that is near the IC04 chip. Now get a pencil and simply color in the part you cut. What this does is have the electricity re-flow through the battery and act normal. (I didn't use this method but it works from what I seen.)
I used a thumbtack to cut the pin and it worked well.
