Default Fatal HIT 3 while booting WP

Guys, whenever i flash a WP rom i get a FATAL HIT3 error in MAGLDR
Android roms on nand and Stock Roms work perfect.

Earlier i had the same issue and i flash the LEO70 rom, which opened the key to it and booted WP, after that i could boot any WP

Then i installed WM for some reasons and now wen i try to flash WP back , it wont boot.

None of the roms work..i tried LEO70 , stock WP based roms, custom 7.8 roms..none!

but if i flash WM stock, it works perfectly..

can anyone help?
Iv tried posting to different places, but no one has an answer..

EDIT : I found a solution
