Pandora Battery + Memory Stick: PSP Slim vs. Fat CFW Install Differences

You cannot use a PSP Slim Pandora Battery + Memory Stick to install CFW on an original PSP (Phat/1000).

Why They're Incompatible

• Pandora Battery: Hardware-modified battery (ID 0xFFFF) triggers Service Mode only on Slim (2000/3000) motherboards with TA-085v2/TA-088v3+ CPUs.
• Phat (1000) Uses Different Exploit: Requires Magic Memory Stick + original battery + specific firmware (3.52 M33, 5.00 M33, 6.60 PRO/ME). No Pandora needed.
• Memory Stick Format: The IPL (Initial Program Loader) on the stick is compiled for the target motherboard CPU revision.

Correct Phat CFW Path (2024)

1. Identify motherboard (TA-079, TA-081, TA-082, TA-086).
2. Ensure OFW ≤ 6.61 (all Phats support permanent CFW).
3. Create Magic Memory Stick using PSP CFW Tool or EasyInstaller on PC.
4. Run installer from Game menu → Install 6.61 PRO-C2 / ME-2.3 / LME.

Warning: 3000/Go/Street models cannot run permanent CFW (only temporary HEN). Pandora works only on hackable 2000/early 3000.
