thinkbook 14,15 g4 iap bios bin NEED

[mferna14]

I matched the BIN before programming... Header was 100% same on both but in the middle the DATA was different. You did it very well & the BIOS even was read perfectly. For where did you get the FF FF photo, in the start it was all yy on both???? We are using the RT809H programmer, the program gives the right match for the chip with voltage. This is a 1.8V chip 256KB. Thanks

I used Neoprogramer 2.2.0.10. and CH341 flasher I2C protocol socket. Just 2 days ago I ordered SOP8 DIP8 connectors and 1,8V adapter, hoping that I would flash the BIOS chip of this laptop, thinking that the BIOS chip is 1,8V supplied. According to boardview the BIOS chip was supplied with 3,3 V, I also measured with multimeter right on the motherboard and the supply voltage was 3,3V, datasheet says supply voltage 1,8 - 5,5V. The same is with the U15 chip, I checked datasheet and range is 1,8 - 5,5V. On boardview the supply voltage for PD controller memory is 3,3 Volts. Neoprogrammer recognized the chip as 3,3V so I proceded with that voltage. Anyways, I am happy for You, that the laptop is ON again.
