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 ??

BLK_MAKE_REQUEST(9)						   Block Devices					       BLK_MAKE_REQUEST(9)

NAME
blk_make_request - given a bio, allocate a corresponding struct request. SYNOPSIS
struct request * blk_make_request(struct request_queue * q, struct bio * bio, gfp_t gfp_mask); ARGUMENTS
q target request queue bio The bio describing the memory mappings that will be submitted for IO. It may be a chained-bio properly constructed by block/bio layer. gfp_mask gfp flags to be used for memory allocation DESCRIPTION
blk_make_request is the parallel of generic_make_request for BLOCK_PC type commands. Where the struct request needs to be farther initialized by the caller. It is passed a struct bio, which describes the memory info of the I/O transfer. The caller of blk_make_request must make sure that bi_io_vec are set to describe the memory buffers. That bio_data_dir will return the needed direction of the request. (And all bio's in the passed bio-chain are properly set accordingly) If called under none-sleepable conditions, mapped bio buffers must not need bouncing, by calling the appropriate masked or flagged allocator, suitable for the target device. Otherwise the call to blk_queue_bounce will BUG. WARNING
When allocating/cloning a bio-chain, careful consideration should be given to how you allocate bios. In particular, you cannot use __GFP_WAIT for anything but the first bio in the chain. Otherwise you risk waiting for IO completion of a bio that hasn't been submitted yet, thus resulting in a deadlock. Alternatively bios should be allocated using bio_kmalloc instead of bio_alloc, as that avoids the mempool deadlock. If possible a big IO should be split into smaller parts when allocation fails. Partial allocation should not be an error, or you risk a live-lock. COPYRIGHT
