Utility originally designed for Asus P527 but it was modified to work with Asus P526.
It will NOT overwrite IPL and BOOT so it's safe to use it.


Address space of P526.PIM file: 
0x0 - 0x1000 - technical information used by P526UU.exe utility (not XORed) 
0x1000 - 0x3201000 - ROM file ROMGalaxy.nb0 (XORed) 
0x3201000 - 0x3701000 - Radio firmware - GSMFFS W8.6.64UK (XORed) 

You need to XOR the whole file using base of 23 to restore original file
("XorByte p526.pim 23" in cmd.exe). After that you can extract any part you need by unsplitting the source file.
