Packard Bell EN-TJ76 dump bios

[TangoSX]

Good afternoon, I desperately ask for your help.
I have a packard Bell Easy note TJ76, model TJ76-JO-433SP whit motherboard SJV50-CP
In an attempt to update bios by usb from cmd, I noticed that it took almost an hour, I let it finish, and after restarting it, now when I put the power plug, it starts up only and does not give an image, black screen.
I have a usb programmer for bios, but when disassembling the pc, I have seen that the board has two bios!
I don't know which of the two I have to flash and which files to put.
I need the dump of both bios.
Thank you for your attention.

write U20 with PV50126.ROM and U17 with W05GW320, but before writing make copies of both bios and check them with the HxD program.

It doesn't matter, make a copy of the contents of both chips, then program the main bios chip file first and test, if there is no result then program the second chip.

Peel off the white stickers on both chips, and write their markings here.

U20= 25X32VSIG 0938
U17= MX12G (or 6?) 25L100S(or 5?)MI
These are.
And many thanks already!

OK, so Peste was right, as he has already said first program the file PV50126.ROM.bin on a chip U20 and test.
If the laptop works - OK, if not program the second file W05GW320.bin to U17.

If both files are right for this particular model (and you program them to the chips correctly), everything should work.
