Dead (?) 5500 [solved], Flash working, Diag working, not booting Options

[RoVeR_Orna]

I've got "small" problem with my SL-5500 - it's not booting. It don't even try to boot. Battery and AC are working well, I can start diag menu or flash zaurus (it takes about 3 minutes). It was working, and once after inserting battery it just won't start. I've already tryed flashing with OZ 3.5.4, and Sharp Ospack 2.37, 3.13 and 3.1. Everytime the same - don't boot, screen is off, no light, no sound, nothing. Is there any chance to repair it??

In diag menu when I press "v" I see something like that:

CODE

CPU      : SA1110 B5
ROM      : USA 3.10
Board    : 01
ROM C.S. : 9f6d
Model    : 0002

BOOTSHP2 : 20020126 785a
CF       : 20020126 fd5d
COLLIE   : 20020221 e44d
ZIMAGE   : 20030509 97ed
ROMDISK  : 20030426 ad7c

This one is for Sharp OS 3.1, but BOOTSHP2, CF and COLLIE checksums aren't changeing after flash, so I think that there can be something wrong with them.
Could anybody send checksums from working SL5500??


-----EDIT-----

PROBLEM SOLVED
I flashed with Sharp's ROM 1.02, and in my diag menu new (4th) page appeared. On that page I get to Flash Tools -> Erase Factory Default. After that I flashed it with OZ - and it works
