Hello guys, have a big problem. Updated laptop bios to version F23 (hp15-cx0514na) and its after update restarts and looks all good. I shut down it and then try to start again and its not boot anymore. Caps lock is flashing 5long.3short which indicates that BIOS is corupted. I have EEProm programer CH431A and downloaded bios from HP the old one which was working before i done update. Flashed to the Bios chip but still no luck . It is 2 bin files 08477.bin 8 mb and 08478.bin 16mb.I checked the old faulty bios (saved from bios before erase it) is 16MB .So i have used 16MB bin file .Checked and Verified all data match on bios chip. Trying to boot still same .Caps lock blinking.Maybe i missed something .Who can help me to sort this out .Will pay for it guys.Its customer laptop and i need it done ASAP.

Please help !!! Sad
