RE: HowTo - manually decompress PRX's (not for PSP experts ^^)
Excuse, me have asked to tell more in detail, as decompress recovery.prx.

1. Open the PRX with your favourite HexEditor.
If the file starts with ~PSP, the file means is packed.
If in Offset: 0x150 there is an offset 1F 8B, it means archive Gzip.

2. Select the first 150 byte

3. Press key Del (Delete), to delete the selected area.

4. Press in the menu "File » Save As..." and save a file as recovery.prx.gz

5. Open and extract the *.gz-archive with 7-Zip or WinRAR. Now you have the decompressed (decrypted) PRX.

6. If you see ELF characters in the file beginning, means before you - decripted & decompressed a file.
