Hello to all, iam Henry and from Germany
me and my wife own two Lenovo X1 Carbon Gen 6 Notebooks (20KH). One has working thunderbolt 3 port, the second one thunderbolt doesnt work and can only power on USB-C Port will charge the battery. The working device has a mfg date from 19/04, the machine with the not working Thunderbolt port was manufactured in 18/4.
Both units do have the same Winbond 25Q80DVNIG chip on the MoBo.
The Unit with the faulty Thunderbolt chip works normal, when i go to bios and disable the Thunderbolt device in the security section.
After reading a lot about that problem, i registered hin this forum, to inform myself, if there is a simple step-by-step solution in the meantime.
As far as i understand the writtings from forum members, this Winbond Chip was possible destroyed by reaching the end of life beause of a wrong microcode in the SPI EEPROM.update from Intel
I would give the faulty device a try for repairing it by soldering a new 25Q80DVNIG onto the mainboard and try to store the dumped Firmware from the working device and transfer to the faulty X1
Unforunately i am not very familiar with using such programmers, and would like to ask, if there is a detailed explanation for doing such a transfer in the new 25X80DVNIG available.. means which programmer would work and is able to support this SPI?. Are there possible other problems? Whats about the 2 small ICs right from the EEPROM.
I have read, the 25Q80DVNIG should filled with Zero before writting the firmware.
Is it possible to programming the new ordered chips outside the mainboard or do i have to soldering first the IC and then reflash the IC.
As you can see, there are lots of questions and i ask for a helping advice.
Kindly regards
Henry
