Hello, i got a Sony Vaio laptop SVP132A1CM (nothing to find, another possible model-number seems to be SVP1321C5E or SVP1321S1EBI). After bios-update (AMI Aptio 4) with manual and UBU-modified bios, it seems to work, but has blackscreen and no output on HDMI-port. I guess something goes wrong with the vga-bios or gop. I have a copy before updating bios. What was modified: -manual replacing latest microcode and adjusting the _FIT_-table with UEFI-tool and hexeditor -manual replacing vga-bios (haswell mobile) from 2171 to 2175 with MMTool, settings transfered with Intel BMP utility -GOP-driver updated with UBU, from 5.0.1025 to 5.0.1034 -flashed with DOS-tool AFUDOS with /GAN-command because of secureflash -flash memory is Winbond W25Q64 1,8V SPIFLASH, EF4017 in VSCC-table Any idea for restoring or repairing the bios? Or only reprogramming with spiflasher? Thanks!
