qosmio f50-freeze when trying to update bios-black screen

Hi! I own a Qosmio f50 laptop and today i download the file from toshiba to update my bios. Everything went well until installer reaches block 16 when system freezes. I left it half an hour and then tried to power-off the pc with the button, but it dont. I unplug the ac-adaptor and the battery and it closes, but when i power it on again I get a black screen..
What should i do? I read something about phoenix crisis disk with which i can get the bios work again.

After hours of forum-searching i give it a try:
First, i dont have usb floppy so wincris.exe didn't help me. Is possible this to be done with usb stick? and if yes what usb port should i use?

I tried an application which i found on a forum called 268076.exe with which i put inside a fat16 formatted usb drive 3 files. After i didnt know where to find my bios. I went to toshiba site and download BIOS update and unzip it and use the skaa240a.rom file. I rename it to BIOS.WPH and pull the stick into laptop. Followed some instructions to put laptop in crisis recovery mode (Fn+b during powering it on, i think i did it because no led light up) and let it about 20 minutes. Nothing happens.

Also using hp usb disk storage format tool create another bootable usb with the same bios but i get nothing again. i used this guide Bios Recovery Procedures .

Any help please ??

BIO_ALLOC_BIOSET(9)						   The Linux VFS					       BIO_ALLOC_BIOSET(9)

NAME
bio_alloc_bioset - allocate a bio for I/O SYNOPSIS
struct bio * bio_alloc_bioset(gfp_t gfp_mask, int nr_iovecs, struct bio_set * bs); ARGUMENTS
gfp_mask the GFP_ mask given to the slab allocator nr_iovecs number of iovecs to pre-allocate bs the bio_set to allocate from. DESCRIPTION
If bs is NULL, uses kmalloc to allocate the bio; else the allocation is backed by the bs's mempool. When bs is not NULL, if __GFP_WAIT is set then bio_alloc will always be able to allocate a bio. This is due to the mempool guarantees. To make this work, callers must never allocate more than 1 bio at a time from this pool. Callers that need to allocate more than 1 bio must always submit the previously allocated bio for IO before attempting to allocate a new one. Failure to do so can cause deadlocks under memory pressure. Note that when running under generic_make_request (i.e. any block driver), bios are not submitted until after you return - see the code in generic_make_request that converts recursion into iteration, to prevent stack overflows. This would normally mean allocating multiple bios under generic_make_request would be susceptible to deadlocks, but we have deadlock avoidance code that resubmits any blocked bios from a rescuer thread. However, we do not guarantee forward progress for allocations from other mempools. Doing multiple allocations from the same mempool under generic_make_request should be avoided - instead, use bio_set's front_pad for per bio allocations. RETURNS
Pointer to new bio on success, NULL on failure. COPYRIGHT
