Hello, I have Sony Vaio SVF1521A4E and wont to reinstall the recovery BIOS because I installed wrong BIOS update from other Sony Vaio so the laptop will not start is just on and off every few sec, I did everything with trying to recovery Bios but no luck. Sure, I used wincrisis and its going fine but when inserting the USB 4GB the laptop won’t read the BIOS.
My question is there any special name for BIOS its original name R0250DA.ROM and changed to BIOS.WPS to let wincrisis works. But no luck at the laptop won’t read it I test all this buttons FN + B, FN + R, FN + ESC, WIN + B, Win + R, WIN + ESC!!!
