Hi all.

Please can help me.
After external reprograming BIOS and EC, notebook not work.
After connect power cord, keyboard backlight ON, power LED ON, all others LED is ON and nothing on display.
Fan is full speed.
CapsLock LED flash 5 times (General system board failure)
If I long push power button notebook is normal off.
I dont know where is problem.
This problem I have only on HP 840 G3.
With others notebook I don't have problem Lenovo, Apple, HP G0-G2 etc.
All contacts on the FLASH is OK.

Thanks

It is possible that during flash removal you have affected the components around the flash such as: the resistor is damaged or lost
I have met many of the above.
BTW, during flash loading you should pay attention to the right kind of flash support:
For example:
GD25B128C [SOP8-200] (QuadSPI)
GD25B128C [SOP8-200] (Quad I / O)
GD25B128C [SOP8-200] (DualSPI)
GD25B128C [SOP8-200] (Dual I / O)
This line, if used with Flash Gigabyte, is QuadSPI
